    Appeal from the United States District Court
    for the Northern District of Georgia
    ________________________
    (February 2, 2012)
    Before HULL, MARCUS and BLACK, Circuit Judges.
    PER CURIAM:
    Following a jury trial, Walter Sanders, Jr., appeals his convictions for
    conspiring to possess with intent to distribute five kilograms or more of cocaine in
    violation of 21 U.S.C. §§ 841 and 846, and for aiding and abetting possession with
    intent to distribute five kilograms or more of cocaine in violation of 18 U.S.C. § 2
    and 21 U.S.C. § 841. After review of the record and oral argument, we affirm.
    I. PROCEDURAL BACKGROUND
    A. Sanders’s Arrest
    In June 2006, Immigration and Customs Enforcement (“ICE”), a division of
    the U.S. Department of Homeland Security, began investigating Gracie Priscilla
    Medina for distributing cocaine on behalf of two drug cartels. Through a
    confidential informant, ICE learned that a commercial tractor–trailer carrying a
    concealed load of cocaine was bound for one of Medina’s distribution centers in
    Fayetteville, Georgia.
    On May 7, 2007, ICE alerted the Georgia State Patrol (“GSP”) to look out
    for the tractor–trailer. An officer with the GSP stopped the tractor–trailer, which
    was driven by Defendant Sanders, for various traffic and equipment violations.
    The video camera in the GSP vehicle recorded what happened during the traffic
    stop, which led to Sanders’s arrest. After obtaining Sanders’s consent, GSP
    officers searched both the tractor and the trailer. They discovered 153 kilograms of
    cocaine hidden in a pallet of cabbages, which were rotting because the refrigeration
    unit in the trailer was inoperable. Sanders was arrested on state charges.
    2
    B. Sanders’s Indictment on Federal Charges
    In 2008, a federal grand jury indicted Sanders on the present drug charges.
    Specifically, the superseding indictment charges that (1) Sanders, Medina, and two
    others—Daniel Marillo, Jr., and Salvador Marillo—conspired to possess with
    intent to distribute five kilograms or more of cocaine and (2) Sanders and Salvador
    Marillo aided and abetted others to possess with intent to distribute five kilograms
    or more of cocaine.1
    Daniel and Salvador Marillo pled guilty to the drug conspiracy charged in
    the indictment. Medina pled guilty to a conspiracy charged in a separate
    indictment. All three cooperated with the government. Sanders proceeded to trial.
    C. Motions to Suppress and Other Pretrial Matters
    Before Sanders’s trial, the government submitted both a “Sentencing
    Information Establishing Prior Conviction for the Purpose of Increased
    Punishment” and a notice that the government intended to introduce Sanders’s
    1988 conviction for selling marijuana. Sanders moved in limine to exclude
    evidence of his 22-year-old marijuana conviction as too remote and dissimilar
    from the present offense. Sanders also moved to suppress (1) his statements
    1
    The indictment also includes a forfeiture provision, which applies only to Medina and is
    not at issue in this appeal. Before this federal indictment, the state charges against Sanders were
    dismissed.
    3
    during the traffic stop and (2) the cocaine seized from his tractor–trailer.2
    At a suppression hearing on the eve of trial, the district court heard
    testimony from Sanders and the GSP officer who stopped the tractor–trailer. The
    government played an hour-long video of the traffic stop shot from the GSP
    vehicle. The district court found that the video clearly showed that Sanders
    consented to the search of both the tractor and the trailer. The district court denied
    the motion to suppress (1) the cocaine seized during the traffic stop and (2) his
    statements during the traffic stop. As to his prior marijuana conviction, the district
    court denied Sanders’s motion in limine without prejudice to renewal during trial.
    II. TRIAL EVIDENCE
    At trial, several law-enforcement witnesses testified about both what
    occurred at the traffic stop and the background of the government’s investigation.
    Sanders’s co-conspirators testified about both the load of cocaine charged in the
    indictment and a previous load of 7,700 pounds of marijuana that Sanders
    transported from Texas to North Carolina.
    A. Federal Investigation of Medina
    The government’s first witness was Agent Andre Kenneybrew, a special
    2
    Sanders’s motion also sought to exclude statements at his re-arrest on federal charges,
    but there were no such statements.
    4
    agent with ICE. Agent Kenneybrew testified that in 2006 he began investigating
    drug activity by Gracie Priscilla Medina. Through confidential informants, Agent
    Kenneybrew learned that Medina worked for a drug-trafficking organization run
    by Dimas Gonzalez (the “Gonzalez organization”) and that Medina was
    responsible for collecting money and acquiring warehouses in the Atlanta area.
    Medina was instructed to lease the warehouses and “make it appear as if it was a
    legitimate business. The organization would then send drugs concealed in
    legitimate loads of merchandise from Mexico to Atlanta.”
    When a tractor–trailer was arriving in the Atlanta area, Medina was
    responsible for coordinating the delivery. Medina kept a separate cellular phone
    only for calls from the drivers of the delivery trucks. She was “instructed to
    answer the phone professionally with the business name and give the driver
    instructions on how to get to the warehouse and set up a time for delivery.”
    Although electronic surveillance and wiretaps were used in the Medina
    investigation, Agent Kenneybrew was never able to intercept conversations
    between Medina and the truck drivers. Medina used a separate phone to talk to
    the truck drivers and the agents were unable to intercept the phone numbers.
    Medina dated a man named Roberto Garcia, who belonged to a separate
    drug-trafficking organization run by Daniel Marillo, Jr., and Salvador Marillo (the
    5
    “Marillo organization”). Garcia eventually went to jail, and Garcia asked Medina
    to collect money for the Marillos. Medina was thus involved in two separate drug-
    trafficking organizations.
    On cross-examination, Agent Kenneybrew testified that, as with the
    Gonzalez organization, the truck drivers for the Marillo organization were
    unaware that they were transporting drugs and believed that they were transporting
    legitimate loads. Although ICE was monitoring phones of the Gonzalez
    organization, ICE was not monitoring the phones of the Marillo organization.
    Medina pled guilty to money laundering and trafficking marijuana, agreed
    to cooperate with the government, and also testified at Sanders’s trial. Medina’s
    testimony largely corroborated Agent Kenneybrew’s. As explained later, Medina
    testified that she had two phone conversations with Sanders but otherwise did not
    know who he was.
    B. The Day of the Traffic Stop
    In May 2007, Agent Kenneybrew learned from a confidential source that a
    tractor–trailer was scheduled to arrive at a warehouse in Fayetteville, Georgia.
    Agent Kenneybrew contacted local police, who surveilled the warehouse
    beginning on May 7, 2007. Around noon, the local police informed Agent
    Kenneybrew that the tractor–trailer had arrived at the warehouse. Before Agent
    6
    Kenneybrew arrived on the scene, the local police called back and said that the
    tractor–trailer was leaving the warehouse without unloading anything.
    One of the police officers surveilling the warehouse testified that the
    tractor–trailer was at the warehouse for no more than ten or fifteen minutes. The
    surveillance officer watched Sanders exit the tractor and Salvador Marillo exit his
    vehicle, and “[f]rom their hand gestures and body language [the officer] could tell
    that [Marillo] was trying to show [Sanders] how to negotiate his truck to back it up
    to the loading bay.” A confidential source told Agent Kenneybrew that Sanders
    had refused to unload because he “did not like the location of the warehouse and
    wasn’t comfortable unloading there.”
    During her testimony, Medina confirmed that, on May 7, 2007, she received
    a call from the truck driver asking for directions, and she gave the truck driver
    directions to the Fayetteville warehouse. Medina testified that she did not answer
    this phone call by identifying herself—she simply answered the phone and gave
    the driver directions to the warehouse. Later that day, Medina received another
    call from the truck driver, who stated that he did not want to unload at the
    warehouse because “he was uncomfortable,” the location was “too narrow” to
    make a delivery, and he was upset that no one was there when he arrived. Medina
    had never received any similar complaints about the warehouse, and she told the
    7
    truck driver to talk to Marillo. Salvador Marillo subsequently told Medina that the
    delivery would occur at another location.
    In any event, the local police followed Sanders’s tractor–trailer—which was
    following a red Volkswagen belonging to Salvador Marillo—to a nearby truck
    stop. At the truck stop, Sanders exited the tractor and joined Salvador Marillo in
    the red Volkswagen, and they drove away. That afternoon, Agent Kenneybrew
    contacted GSP and asked them to prepare a “whisper stop,” in which ICE tells a
    local law enforcement agency that a vehicle contains drugs or other contraband but
    asks the local agency to develop its own probable cause for the stop to avoid
    compromising the federal investigation. Around 8:00 p.m., the red Volkswagen
    returned to the truck stop, and Sanders returned to the tractor–trailer and followed
    the red Volkswagen out of the parking lot. Agent Kenneybrew notified GSP,
    which subsequently stopped the tractor–trailer for traffic and equipment
    violations.
    C. The Traffic Stop and Seizure of Cocaine
    The government also called Officer James Lamar Thompson, the GSP
    officer who stopped Sanders’s tractor–trailer on May 7, 2007. Although ICE
    notified him to look out for the vehicle, Officer Thompson stopped Sanders’s
    tractor–trailer because he saw Sanders illegally cross three or four lanes of traffic
    8
    and noticed several equipment violations on the tractor–trailer. When Officer
    Thompson activated the blue lights to notify Sanders to stop the tractor–trailer, a
    dash-mounted camera began recording video of the events in front of the police
    vehicle. A microphone attached to Officer Thompson’s uniform made an audio
    recording of the traffic stop.
    The government played for the jury the hour-long video of the traffic stop
    while Officer Thompson narrated the events shown on the video. During the
    traffic stop, Sanders verbally consented to a search of both the tractor and the
    trailer, and he also signed two consent-to-search forms. Officer Thompson wrote
    Sanders citations for the traffic violation and various equipment violations while
    another officer, Dallas VanScoten, searched the trailer for narcotics.
    After the video played, Officer Thompson authenticated several documents
    provided by Sanders during the traffic stop. Sanders provided (1) a commercial
    driver’s license, (2) several registration cards showing that the tractor was
    registered to Kelvin Snead but reporting different license numbers, (3) a certificate
    of insurance, (4) a “cab card” for the tractor, (5) an inspection report dated January
    12, 2007, and (6) a bill of lading, which indicated that Sanders’s load of cabbages
    was scheduled for delivery at 5:00 a.m. the next morning in Raleigh, North
    Carolina. Officer Thompson testified that the registration cards raised a red flag
    9
    because Sanders presented two registration cards for the same vehicle. Officer
    Thompson obtained the second consent-to-search form so that the consent form
    showed either of the two possible registration numbers.
    Additionally, the bill of lading concerned Officer Thompson because
    Sanders personally signed the bill of lading, the phone number for the shipper
    contained too many digits (11 digits instead of 10), and the loading date was May
    4, 2007, in Edinburg, Texas. Officer Thompson testified that this was odd because
    (1) he stopped Sanders three days later on May 7, 2007, (2) Edinburg, Texas, was
    only 18 to 20 hours away, and (3) Sanders was carrying perishable cabbages and
    knew that the trailer’s refrigeration unit was broken. A line on the bill of lading,
    titled “Special Instructions to Trucker,” stated, “Drivers must maint. temperature
    at 36 F at all times.” Officer Thompson testified that a legitimate truck driver
    would be more concerned with the integrity of the load because he would have to
    deliver the load before being paid.
    Sanders also provided Officer Thompson with two receipts for repair work
    performed on the tractor–trailer. The first receipt, dated April 25, 2007, showed
    work done to other parts of the tractor and trailer but no work on the refrigeration
    unit. The second receipt, dated May 6, 2007, which was the day before the stop,
    showed that a fan belt was replaced but showed no work performed on the
    10
    refrigeration unit.
    The government then called Officer Dallas VanScoten, another GSP officer.
    Officer VanScoten testified that Sanders’s trailer did not appear professionally
    loaded because many of the boxes of cabbages were tilted or crushed. Sanders
    told Officer VanScoten that he had stayed in a motel, which was unusual because
    truck drivers typically sleep in their tractors to save money. After Sanders
    consented, Officer VanScoten searched the trailer by crawling from the back to the
    front on top of the rows of pallets full of rotten cabbages. Officer VanScoten
    could search only the top row of pallets and failed to find any drugs. Officer
    VanScoten then exited the trailer and used a trained narcotics-detection dog, who
    alerted several times to the odor of narcotics coming from the trailer.
    Around 9:30 p.m., the GSP officers moved the tractor–trailer to a nearby
    parking lot to search the trailer. Agent Kenneybrew participated in unloading the
    trailer, which contained pallets of rotting cabbages. The government showed
    several photographs of the trailer and the cargo as it was being unloaded. In one
    of the pallets in the second row from the front (i.e., the tractor side) of the trailer,
    the agents discovered 153 kilograms of cocaine under a pile of rotting cabbages.
    At the time, each kilogram of cocaine had a street value of approximately
    11
    $28,000.00.3
    D. Co-conspirator Reyes’s Testimony About an Earlier Load of Marijuana
    The government also presented the testimony of co-conspirator Eric Adrian
    Reyes, who was currently serving a prison sentence after pleading guilty to
    conspiracy to distribute cocaine.4
    At age twelve, Reyes met Eddie Snead, who got Reyes involved in selling
    crack cocaine. Before turning 21 years old, Reyes had three state drug convictions
    and served 35 months in prison. While in prison, Reyes met Manuel Sanchez,
    who had connections to drug traffickers in Texas.
    About six months after Reyes was released from prison, Sanchez introduced
    Reyes to Mario Cavazos, another drug trafficker. Sanchez and Cavazos were
    looking for vehicles to transport drugs, and Reyes sold them two vehicles in
    exchange for drugs. Shortly afterward, Reyes re-entered the drug business and
    began working with Cavazos to import large amounts of marijuana and cocaine
    from Texas to North Carolina.
    3
    Sanders was arrested on state charges because ICE was not ready to indict all the
    co-conspirators in the federal investigation. Because the federal investigation remained ongoing
    when the state charges had to be resolved, Agent Kenneybrew instructed the state officials to
    release Sanders and drop the state charges to allow ICE to include the charges in a forthcoming
    federal indictment.
    4
    Reyes was charged in North Carolina, pled guilty to conspiracy to distribute five
    kilograms or more of cocaine, and agreed to cooperate with the government.
    12
    Reyes was responsible for coordinating deliveries of narcotics, but he also
    had his own list of customers to whom he sold. One customer was Kelvin Snead,
    who amassed a drug debt of more than $100,000.00 and was Eddie Snead’s
    cousin. Reyes knew that Kelvin Snead had a hauling business and that Cavazos
    was looking for a tractor–trailer. Kelvin Snead agreed to provide the tractor if
    Reyes purchased a refrigerated trailer. Reyes purchased the trailer in Kelvin
    Snead’s name for approximately $7,500.00 cash. The refrigeration unit was
    working when he purchased the trailer. Reyes testified that the “sole purpose” of
    purchasing the trailer was to traffic narcotics from Texas to North Carolina.
    According to Reyes, the tractor–trailer would be driven to Texas, where
    someone would arrange for a load of produce—called a cover load—in which to
    hide the narcotics. The drugs would be placed near the front of the trailer, and the
    rest of the trailer would be filled with produce. Although Reyes had the truck and
    the trailer, Kelvin Snead was responsible for hiring a driver, and his main driver
    was Sanders.5
    In March 2007, Reyes, Cavazos, Kelvin Snead, and Sanders participated in
    the first trip using the newly purchased trailer. Reyes, Cavazos, and Kelvin Snead
    5
    On cross-examination, Reyes admitted that Kelvin Snead also ran a legitimate business
    hauling gravel and that Sanders had driven legitimate loads for Kelvin Snead in the past.
    13
    met to plan the trip, but Sanders was not present at the meeting. Sanders
    subsequently drove the tractor–trailer from North Carolina to Texas and waited for
    Reyes and Cavazos to prepare the load, and then Sanders drove the tractor–trailer
    to the loading dock in Texas. Only Reyes and Cavazos organized the load;
    Sanders waited at a truck stop until the load was ready. For this trip, 7,700 pounds
    of marijuana were loaded on the truck, hidden in a cover load of cabbages.
    Sanders did not help load the trailer.
    For the return trip to North Carolina, Cavazos led a caravan in his own car,
    followed by Sanders in the tractor–trailer, followed by Reyes driving his own car.
    Reyes testified that they drove in this order to “take care of the load” and to watch
    for law enforcement. If the trailer had contained only cabbages, Reyes and
    Cavazos would not have traveled along with Sanders. At a checkpoint in Texas,
    Reyes was stopped by law enforcement, who searched his vehicle. Reyes was
    relieved to see that Sanders made it through the checkpoint undetected. Sanders
    then pulled over to wait for Reyes, and Reyes had to call Sanders to tell him to go
    ahead without him. Before leaving Texas, the caravan stopped in Houston to
    unload 4,400 pounds of marijuana. Sanders was present while the marijuana was
    being unloaded but did not help unload the trailer.
    The rest of the return trip was uneventful until Sanders was driving through
    14
    South Carolina and jack-knifed the tractor–trailer trying to avoid a car merging on
    to the interstate. Although law enforcement arrived on the scene, the driver of the
    car admitted that the accident was her fault, and law enforcement never searched
    the trailer. Sanders then drove to Kelvin Snead’s shop in North Carolina, where
    the remaining 3,300 pounds of marijuana were unloaded. Sanders was on location
    when the marijuana was unloaded, but he did not help unload the trailer and
    remained inside the shop waiting to be paid.
    Reyes testified that Sanders was originally supposed to be paid $50,000.00
    for the marijuana trip, but Cavazos subsequently lowered Sanders’s share to
    $30,000.00. After receiving an initial payment of approximately $9,000.00,
    Sanders demanded more money “because he found out there was narcotics” in the
    trailer. Reyes and Cavazos eventually gave Sanders 40 pounds of marijuana as
    additional payment for driving the tractor–trailer. In Reyes’s experience, a truck
    driver would typically charge only $3,300.00 to drive a load of legal merchandise
    from North Carolina to Texas.
    Several weeks later, Sanders drove the tractor–trailer back to Texas to pick
    up another load. Subsequently, Cavazos told Reyes that Sanders was caught in
    Georgia with 153 kilograms of cocaine. Reyes gave approximately $15,000.00 to
    Kelvin Snead to pay for a lawyer for Sanders. Reyes did not believe that Snead
    15
    ever used the money to hire a lawyer. As far as Reyes knew, Sanders had driven
    only the two loads—the first load of marijuana and the second load of cocaine for
    which he was on trial.
    E. Co-conspirator Richards’s Testimony About the Cocaine Load
    The government also called co-conspirator Aaron Lamar Richards, who was
    currently serving a 132-month sentence for conspiracy to distribute cocaine.
    Richards used to deal cocaine with Eddie and Kelvin Snead. In 2007, Richards
    talked with the Sneads about an imminent load of cocaine that was going to be
    delivered from Texas. Richards and the Sneads were discussing the cocaine
    delivery when Sanders arrived. During the conversation, Sanders told Kelvin
    Snead that Sanders planned to change his route during this trip because he
    encountered too many cops on the route he took during his last trip.
    Eddie Snead told Richards that Sanders was preparing to drive the
    tractor–trailer to Texas to pick up cocaine, and Richards agreed to buy 20
    kilograms of cocaine from the load at $26,000.00 per kilogram. Richards never
    received the cocaine because Sanders was caught in Georgia and the cocaine was
    seized.
    About a year later, Richards ran into Sanders at a restaurant in North
    Carolina, and Sanders stated that he had “beat the case down in Atlanta” and was
    16
    released. Richards suspected that Sanders’s release meant that he was likely to be
    indicted by the federal government, but Richards did not reveal this suspicion. On
    cross-examination, Richards conceded that he knew that Sanders was going to face
    federal charges because Richards was recently arrested on federal drug charges
    and was released after agreeing to cooperate and collect evidence on his co-
    conspirators.
    F. Sanders’s 1988 Marijuana Conviction
    After this testimony, the government renewed its Rule 404(b) request to
    admit Sanders’s 1988 conviction for selling 1.4 grams of marijuana. The
    government argued that the conviction was probative of Sanders’s intent to enter
    into the drug conspiracy. Sanders responded that the 22-year-old conviction was
    too remote to be probative and that a street-level sale of 1.4 grams of marijuana
    was too dissimilar to the international drug-trafficking conspiracy at issue to be
    probative of Sanders’s intent.
    The district court admitted the 1988 conviction but gave a cautionary
    instruction. The court instructed that the jury could consider the prior conviction
    only for the “very limited purpose” of determining whether Sanders had the state
    of mind or intent to commit the crimes charged in the indictment. The government
    rested.
    17
    Sanders moved for a judgment of acquittal. The district court denied the
    motion. Sanders presented no evidence.
    G. Jury Charge
    Because Sanders’s appeal involves the jury charge, we also review what
    happened in that regard.
    During closing arguments, defense counsel argued that Sanders was “just a
    truck driver” and that the government had failed to prove that Sanders knew he
    was hauling cocaine in the cabbages. Defense counsel asserted that the
    government “could have charged him with marijuana,” and had “let one of his
    codefendants Ms. Medina plead guilty to marijuana,” but the government was
    trying to “put this whole truckload of cocaine on Walter Sanders.” Continuing
    with this theme, defense counsel argued that Sanders “obviously has a thing for
    marijuana” but “[t]hat doesn’t mean he has a thing for cocaine.” Defense counsel
    asserted that the government “charged a very particular conspiracy in this case,”
    and specifically charged Sanders, Medina, and two others “with conspiracy to do
    this load of cocaine.” Defense counsel questioned why the government was
    “trying to prove that Walter Sanders particularly knew it was cocaine in that trailer
    when they’re letting other people plead to marijuana[?]”
    In its jury instructions, the district court stated that, to convict Sanders of
    18
    the conspiracy charged in the indictment, the evidence must show beyond a
    reasonable doubt “that the object of the unlawful plan was to possess with intent to
    distribute more than five kilograms of cocaine, as charged.” After the charge was
    given, the government objected that the charge should have stated merely that the
    object of the plan was to possess with intent to distribute a “controlled substance,”
    rather than any specific drug. In reply, Sanders argued that the indictment
    specifically charged cocaine and that a “controlled substance” charge would
    undercut his defense. Sanders asked that the jury be given the option of
    convicting on the lesser-included offense of conspiracy to distribute marijuana.
    Over Sanders’s objection, the district court called the jury back in and
    instructed that Sanders did not have to know the nature of the particular drug but
    must know that he was possessing a controlled substance.6 After deliberating for a
    6
    The district court charged the jury:
    Ladies and gentlemen, I’m going to try to clear up one thing that arose maybe in the
    closing arguments that I had not specifically and normally do not have specifically
    in my charge, but to clear it up.
    The defendant does not have to—I instruct you that when I was giving the
    elements of the three elements in each instance, I want you to understand that the
    defendant does not have to know specifically the nature of the particular drug that
    he’s possessing, but must know that it is a controlled substance. Now, of course it
    has to be and you have to make those findings that it, in fact, was cocaine because
    that is charged what was possessed. And if you don’t—and you must find the
    quantity, but it’s not an element of the offense under the law. Under the law it is that
    he intended to possess a controlled substance, and then it happened to be whatever
    it might be in this case, alleged cocaine. It could be marijuana or whatever else is
    charged.
    19
    while, the jury asked whether the indictment terms “controlled substance” and
    “cocaine” were interchangeable.7 Over Sanders’s objection, the district court
    advised the jury that the terms “are not totally interchangeable because ‘controlled
    substance’ is a broader term than ‘cocaine’” and “includes many things,” such as
    methamphetamine and other drugs. The district court explained that the defendant
    “only has to have knowledge that it’s a controlled substance” and “he does not
    have to have knowledge that it was actually cocaine that was being possessed.”
    The district court advised that the controlled substance may turn out to be cocaine,
    or marijuana, or methamphetamine, and the jury would also determine the amount
    of the drug involved for later sentencing calculations under the sentencing
    guidelines.
    Sanders iterated his objection to the court’s answer to the jury’s question.
    Less than ten minutes later, the jury returned a verdict of guilty on both counts.
    On the special verdict form, the jury found that Sanders conspired to possess with
    intent to distribute five kilograms or more of cocaine and that he possessed with
    intent to distribute five kilograms or more of cocaine.
    7
    The jury asked:
    In Counts 1 and 2, it uses the following: “controlled substance.” In the . . .
    amounts shown it was the following—“cocaine.” Is the word “cocaine” in the
    statement still interchangeable with the words “controlled substance”?
    20
    H. Sentencing
    Sanders’s presentence investigation report (“PSI”) calculated a total offense
    level of 388 and a criminal history category of II, yielding a guidelines range of
    262 to 327 months’ imprisonment. Given Sanders’s prior drug conviction, he
    faced a mandatory minimum sentence of 20 years’ imprisonment. See 21 U.S.C.
    § 841(b)(1)(A) (“If any person commits such a violation [of § 841(a)] after a prior
    conviction for a felony drug offense has become final, such person shall be
    sentenced to a term of imprisonment which may not be less than 20 years and not
    more than life imprisonment . . . .”).
    At sentencing, Sanders requested a two-level reduction for having a minor
    role in the offenses. The district court denied the reduction based on the trial
    evidence. The district court adopted the PSI’s factual recitations and guidelines
    calculations. After considering the 18 U.S.C. § 3553(a) factors and Sanders’s
    mitigation arguments, the district court sentenced Sanders to concurrent sentences
    of 250 months’ imprisonment on his two convictions.
    III. DISCUSSION
    On appeal, Sanders raises these six errors: (1) improper jury charge that
    8
    The Drug Quantity Table in U.S.S.G. § 2D1.1(c)(1) provides for an offense level of 38
    for a § 841(a) offense involving 150 kilograms or more of cocaine.
    21
    amended and broadened the indictment to include any controlled substance,
    (2) erroneous admission of his 1988 marijuana conviction, (3) insufficiency of the
    evidence, (4) wrongful denial of the motion to suppress evidence seized at the
    traffic stop, (5) wrongful denial of the motion to suppress his statements to the
    police, and (6) improper admission of co-conspirator Richards’s hearsay
    testimony. After review of the record, and given Sanders’s consent to the search
    of his tractor–trailer, we conclude that issues 3, 4, 5, and 6 wholly lack merit and
    do not warrant further discussion. However, issues 1 and 2 require further
    consideration.
    A. Jury Charge and the Indictment
    It is well settled that a defendant enjoys a Fifth Amendment right to be tried
    on felony charges returned by a grand jury indictment and that only the grand jury
    may broaden the charges in the indictment once it has been returned. Stirone v.
    United States, 
    361 U.S. 212
    , 215–16, 
    80 S. Ct. 270
    , 272, 
    4 L. Ed. 2d 252
    (1960).
    The district court may not broaden the charges by constructive amendment. 
    Id. “A constructive
    amendment to the indictment occurs where the jury instructions so
    modify the elements of the offense charged that the defendant may have been
    convicted on a ground not alleged by the grand jury’s indictment.” United States
    22
    v. Starke, 
    62 F.3d 1374
    , 1380 (11th Cir. 1995) (quotation marks omitted).9
    Sanders argues that the district court’s jury instructions impermissibly
    broadened the charges in the indictment by instructing that Sanders did “not have
    to know specifically the nature of the particular drug that he’s possessing, but
    must know that it is a controlled substance.” For the reasons explained below, we
    conclude that this instruction is fully consistent with the statutory requirements
    and our precedent.
    As background, we begin with the language of the relevant statutes. Section
    841(a)(1) provides that “it shall be unlawful for any person knowingly or
    intentionally . . . to manufacture, distribute, or dispense, or possess with intent to
    manufacture, distribute, or dispense, a controlled substance.” 21 U.S.C.
    § 841(a)(1) (emphasis added).10 As is evident from the statutory language, a
    person violates § 841(a) merely by knowingly possessing with intent to distribute
    a controlled substance. The § 841(a) offense is complete once the person commits
    the proscribed act and knows that the substance is a “controlled substance.”
    9
    Both parties agree that the applicable standard of review of the particular issue here is de
    novo.
    10
    Section 846 provides that any person “who attempts or conspires to commit any offense
    defined in this subchapter [including § 841(a)] shall be subject to the same penalties as those
    prescribed for the offense, the commission of which was the object of the attempt or conspiracy.”
    21 U.S.C. § 846.
    23
    “[B]ecause the specific amount and type of drugs are not elements of the
    [§ 841(a)(1)] offense, the government’s failure to prove the amount or type
    charged in the indictment does not merit reversal.” United States v. Baker, 
    432 F.3d 1189
    , 1233 (11th Cir. 2005); see also United States v. Mejia, 
    97 F.3d 1391
    ,
    1392–93 (11th Cir. 1996); United States v. Gomez, 
    905 F.2d 1513
    , 1514–15 (11th
    Cir. 1990).
    At the outset, we also recognize that § 841(b) provides enhanced maximum
    sentences for persons convicted of violating §§ 841(a) or 846, depending on the
    quantity and type of drug involved. 21 U.S.C. § 841(b). Further, the enhanced
    statutory maximum penalties in § 841(b) cannot apply unless the jury determines
    the drug type and quantity involved in the overall drug conspiracy offense. See
    United States v. Sanchez, 
    269 F.3d 1250
    , 1270 (11th Cir. 2001) (en banc) (“[T]here
    is constitutional error in a defendant’s sentencing procedures when drug quantity
    increases a defendant’s sentence beyond the prescribed statutory maximum under
    § 841(b)(1)(C),11 unless it was submitted to a jury and proven beyond a reasonable
    doubt.”); see also Apprendi v. New Jersey, 
    530 U.S. 466
    , 489, 
    120 S. Ct. 2348
    ,
    11
    Section 841(b)(1)(C) provides a maximum penalty of 20 years’ imprisonment for a
    § 841(a) offense involving any amount of any controlled substance in Schedule I or II, which
    includes cocaine. Section 841(b)(1)(B) increases the statutory maximum to 40 years’
    imprisonment for an offense involving 500 grams or more of cocaine. Section 841(b)(1)(A)
    increases the statutory maximum to life imprisonment for an offense involving five kilograms or
    more of cocaine.
    24
    2362–63 (2000) (holding that, “[o]ther than the fact of a prior conviction, any fact
    that increases the penalty for a crime beyond the prescribed statutory maximum
    must be submitted to a jury, and proved beyond a reasonable doubt”).
    Although the jury must determine the quantity and type of drug involved,
    nothing in the statute, the Constitution, or Apprendi requires the government to
    prove that the defendant had knowledge of the particular drug type or quantity for
    which a sentence is enhanced under § 841(b). Unlike § 841(a), § 841(b)’s penalty
    scheme imposes no mens rea requirement.12 Rather, § 841(b) refers only to a
    violation of § 841(a) “involving” certain quantities and types of controlled
    substances.
    In other words, Apprendi requires that the indictment must charge—and the
    jury must find beyond a reasonable doubt—that the offense “involv[ed]” a
    particular drug type and quantity before a defendant may receive a sentence above
    the maximum penalty in § 841(b)(1)(C). But, as other circuits have held, the
    defendant’s knowledge of drug type or quantity is not a fact that increases the
    statutory maximum penalty, and therefore Apprendi does not require the jury to
    find that the defendant knew what controlled substance was involved. See, e.g.,
    12
    Sanders’s reply brief acknowledges as much, stating: “Sanders does not argue that the
    district court erred by failing to instruct the jury that the government was required to prove
    specific intent to possess a particular drug.”

    515 F.3d 1268
    , 1276 (D.C. Cir. 2008) (“In short, the
    defendant’s knowledge of the type of drug at issue in his offense is not a ‘fact that
    increases the penalty for a crime beyond the prescribed statutory maximum,’ and
    hence is not a fact that ‘must be submitted to a jury, and proved beyond a
    reasonable doubt.’” (quoting

    substance.”); United States v. Collazo-Aponte,

    219 F.3d 766
    , 768 n.2, 769 (8th Cir. 2000) (same).
    In Sanders’s case, the district court instructed the jury, in varying iterations,
    that the defendant “only has to have knowledge that it’s a controlled substance”
    and “he does not have to have knowledge that it was actually cocaine that was
    being possessed.” These instructions correctly state the law of our Circuit
    applying § 841(a) and (b), and the district court did not amend or broaden the
    indictment by instructing the jury that Sanders did not have to know specifically
    that he possessed cocaine. See 
    Baker, 432 F.3d at 1233
    –34.
    Although knowledge is not required under § 841(b), Sanders argues that his
    27
    particular indictment narrowly charges only a “subset” of the statutory
    offenses—conspiracy to possess and possession of cocaine—rather than the
    generic crimes of conspiracy to possess and possession of a controlled substance.
    We disagree because the precise language of his indictment charges controlled
    substance crimes. For example, Count One charges that Sanders:
    did knowingly combine, conspire, confederate, agree and have a tacit
    understanding with each other and others known and unknown to the
    Grand Jury, to commit violations of Title 21, United States Code,
    Section 841(a)(1), that is, to knowingly and intentionally distribute and
    possess with intent to distribute a controlled substance, said conspiracy
    involving at least five (5) kilograms of cocaine hydrochloride, a
    Schedule II substance, all in violation of Title 21, United States Code,
    Sections 846, 841(a)(1) and 841(b)(1)(A)(ii).
    The indictment tracks the statutory language of § 841(a) by charging that Sanders
    conspired to knowingly and intentionally possess with intent to distribute a
    “controlled substance.” Count One charges a generic violation of §§ 841(a) and
    846 in which Sanders conspired to knowingly and intentionally distribute “a
    controlled substance.” Count Two similarly charges a generic violation of
    § 841(a) in which Sanders knowingly possessed with intent to distribute “a
    controlled substance.”13 We recognize that each count adds sentencing language
    13
    Count Two charges that Sanders and Salvador Marillo:
    aided and abetted by each other and others known and unknown, to knowingly and
    intentionally possess with intent to distribute a controlled substance, said act
    involving at least five (5) kilograms of a mixture and substance containing a
    detectable amount of cocaine hydrochloride, a Schedule II controlled substance, all
    28
    to give Apprendi notice that the government also charged that the overall
    conspiracy “involv[ed] at least five (5) kilograms of cocaine.” This language,
    however, is not required for conviction under § 841(a) but is required to set the
    statutory maximum sentence under § 841(b). Because the indictment charges
    generic, “controlled substance” violations of §§ 841(a) and 846, the district court
    correctly instructed the jury that Sanders had to know only that he was conspiring
    to distribute, and possess with intent to distribute, any controlled substance.
    Contrary to Sanders’s contention, our decision in United States v. Narog,
    
    372 F.3d 1243
    (11th Cir. 2004), does not help him. In Narog, the defendants were
    charged with conspiring to possess and distribute pseudoephedrine “knowing and
    having reasonable cause to believe that the listed chemical [pseudoephedrine]
    would be used to manufacture a controlled substance, that is, methamphetamine.”
    
    Id. at 1246
    (emphasis added). The government prosecuted the Narog case only as
    a methamphetamine-production case. There was no evidence that the
    pseudoephedrine pills would be used to manufacture a controlled substance other
    than methamphetamine. 
    Id. at 1247.
    Therefore, the jury should have been
    instructed that the term “controlled substance” “was synonymous with
    in violation of Title 21, United States Code, Sections 841(a)(1) and 841(b)(1)(A)(ii),
    and Title 18, United States Code, Section 2.
    Given the parallel structure of Counts One and Two, we read them similarly.
    29
    methamphetamine.” 
    Id. at 1249.
    Reversing the defendants’ convictions in Narog,
    this Court concluded that the phrase “that is, methamphetamine” in the indictment
    “essentially charged a subset of the statutory crime.” 
    Id. We also
    stressed that the
    jury “may well have convicted appellants of believing that the pills would be used
    to manufacture a controlled substance other than the one specified therein,
    although there was no evidence of such.” 
    Id. (emphasis added).
    This Court
    concluded that the district court’s instructions unconstitutionally broadened the
    indictment. Id.14
    The material differences here are threefold. First, Sanders’s indictment
    charges generic violations of § 841(a)(1), “that is, to knowingly and intentionally
    distribute and possess with intent to distribute a controlled substance.” Unlike
    Narog, the phrase “that is” in Sanders’s indictment is followed by “controlled
    substance.” Second, unlike in Narog, there was ample evidence that Sanders knew
    he was transporting a controlled substance, and there is no danger that Sanders
    was convicted for an offense not charged by the grand jury. See United States v.
    Behety, 
    32 F.3d 503
    , 509 (11th Cir. 1994) (“The danger that we are concerned
    14
    During deliberations, the jury asked about the “that is” clause: “Did a defendant have to
    have knowledge or reasonable cause to believe the pseudoephedrine would be used to make
    specifically methamphetamine to be guilty?” 
    Id. at 1247.
    Yet, the district court responded that
    the government did not have to prove that the defendant knew the exact nature of the controlled
    substance to be manufactured, only that the defendant knew the pseudoephedrine would be used
    to manufacture some controlled substance. 
    Id. 30 with
    is that a defendant may have been convicted on a ground not alleged by the
    grand jury’s indictment.” (quotation marks omitted)).
    Third, although the indictment here goes further and adds the type and
    amount of drug in the conspiracy, that indictment fairly read is not charging that
    Sanders had knowledge of that type or amount of drug but is charging that the
    overall conspiracy involved that type and amount of drug. Rather, the best reading
    of Count One is that the four named defendants, including Sanders, knowingly
    entered into a conspiracy with intent to distribute a controlled substance, and at
    least five kilograms of cocaine were involved. And, unlike in Narog, the jury’s
    special verdict form in Sanders’s trial specifically finds that the conspiracy
    involved five kilograms or more of cocaine.
    Finally, Sanders argues that the district court erroneously responded to the
    jury’s question by referring to marijuana and to the “weight and quantity of
    cocaine or some other drug, if there was some other drug.”15 Sanders’s argument
    15
    We review for abuse of discretion the district court’s response to a jury question.
    United States v. Lopez, 
    590 F.3d 1238
    , 1247 (11th Cir. 2009). Although the district court enjoys
    “considerable discretion regarding the extent and character of supplemental jury instructions, it
    does not have discretion to misstate the law or confuse the jury.” 
    Id. at 1247–48.
    “A challenged
    supplemental jury instruction is reviewed as part of the entire jury charge, in light of the
    indictment, evidence presented and argument of counsel to determine whether the jury was
    misled and whether the jury understood the issues.” 
    Id. at 1248
    (quotation marks omitted). As
    noted above, however, we review the correctness of jury instructions de novo to determine if they
    misstate the law or mislead the jury to the prejudice of the objecting party. 
    Id. at 1248
    n.7.
    31
    ignores that the district court also instructed that Sanders had “to have knowledge
    that it was a controlled substance. [The controlled substance] may turn out to be
    cocaine or whatever it is, and then you have to determine the amounts for
    sentencing calculations under the sentencing guidelines.”16
    16
    The portion of transcript to which Sanders refers provides in full:
    [“Cocaine” and “controlled substance”] are not totally interchangeable
    because “controlled substance” is a broader term than “cocaine.” It includes many
    things, marijuana, and there are various schedules of controlled substances, it
    includes methamphetamine and other drugs.
    In this case, as you’ve read the indictment and that’s what’s apparently
    causing you some concern, it charges the defendant either in the conspiracy count or
    substantive count, whichever one you want to deal with, but I’ll deal with the
    substantive because that’s a little simpler, with knowingly and intentionally
    possessing with intent to distribute a controlled substance. And then it goes on to
    modify that by saying, said act involving at least five kilograms of a mixture and
    substance containing a detectable amount of cocaine hydrochloride, which is the
    more technical name.
    Now, maybe I should tell you at this time in language that I did not use
    previously, the purpose for those three determinations of weights [in the verdict
    form] relates not to anything you are to do except to find how much—what weight
    and quantity of cocaine or some other drug, if there was some other drug, you found
    goes to the determination that the court must use at sentencing time. And that’s the
    reason for the determination of amounts. Otherwise, the word “cocaine” and the
    weight wouldn’t be there at all, it would just be “controlled substance.”
    Now, where the problem came is an argument was made that the defendant
    had to have knowledge that what . . . he was transporting was, in fact, cocaine. He
    only has to have knowledge that it’s a controlled substance, and that’s the distinction
    I think the lawyers are arguing about presenting to you, and that he does not have to
    have knowledge that it was actually cocaine that was being possessed. He has to
    have knowledge that it was a controlled substance. It may turn out to be cocaine or
    it may turn out to be marijuana or it may turn out to be methamphetamine or
    whatever it is, and then you have to determine the amounts for sentencing
    calculations under the sentencing guidelines. But that’s not a concern of yours except
    to determine that amounts that you say. But beyond that, it’s not your concern. I will
    have to deal with that.
    32
    Although the district court referred to other drugs, the jury charge as a
    whole correctly explains the knowledge required to convict Sanders of the
    offenses charged in the indictment: Sanders had to know that he was possessing a
    controlled substance but did not have to know that the substance was cocaine.
    And, contrary to Sanders’s argument, the district court did not relieve the
    government of its burden to show that five kilograms or more of cocaine were
    involved in the offenses. The district court correctly noted that the government
    retained the burden to identify the type and quantity of drugs involved in the
    offenses and that the jury had to find the drug types and quantities only after
    determining whether Sanders had committed the charged offenses.
    In sum, the grand jury charged Sanders with §§ 841(a) and 846 offenses
    “involving” five kilograms of cocaine, the government presented unrebutted
    evidence that 153 kilograms of cocaine were found in Sanders’s tractor–trailer,
    and the jury specifically found in its special verdict that each offense involved five
    kilograms or more of cocaine. After considering the district court’s instructions in
    context and in light of the trial evidence and the jury’s special verdict, we
    conclude that the jury was not misled into convicting Sanders of a crime for which
    he was not indicted. Because Sanders could not have been convicted of an offense
    for which he was not indicted, the district court’s jury charge did not
    33
    constructively amend or broaden the indictment. See 
    Starke, 62 F.3d at 1380
    .
    B. Admission of Sanders’s Prior Drug Conviction
    Sanders next argues that the district court erred by admitting into evidence
    his 1988 conviction for selling 1.4 grams of marijuana. Relying on Rule 404(b) of
    the Federal Rules of Evidence, Sanders argues that any probative value of the prior
    conviction was diminished by the 22-year gap between the prior conviction and
    the current trial, that the lack of similarity between a street-level sale and a
    153-kilogram trafficking conspiracy reduced the prior conviction’s probative
    value, and that the government had no incremental need to introduce the 1988
    conviction in light of all the other evidence.17
    Rule 404(b) prohibits evidence of another crime, wrong, or act to prove a
    person’s character in order to show action in conformity therewith. FED. R. EVID.
    404(b). This type of evidence is admissible, however, for another purpose, such as
    to prove motive, intent, or absence of mistake or accident (provided that the
    government provides reasonable notice of the general nature of the evidence to be
    17
    We review for abuse of discretion the district court’s decision to admit under Rule
    404(b) Sanders’s prior conviction for selling marijuana. See United States v. Lampley, 
    68 F.3d 1296
    , 1299 (11th Cir. 1995). However, “evidentiary and other nonconstitutional errors do not
    constitute grounds for reversal unless there is a reasonable likelihood that they affected the
    defendant’s substantial rights; where an error had no substantial influence on the outcome, and
    sufficient evidence uninfected by error supports the verdict, reversal is not warranted.” United
    States v. Hawkins, 
    905 F.2d 1489
    , 1493 (11th Cir. 1990).

    introduced at trial). 
    Id. Rule 404(b)
    “is one of inclusion which allows extrinsic
    evidence unless it tends to prove only criminal propensity. The list provided by
    the rule is not exhaustive and the range of relevancy outside the ban is almost
    infinite.” United States v. Ellisor, 
    522 F.3d 1255
    , 1267 (11th Cir. 2008)
    (quotation marks and alteration omitted).
    To be admissible, the Rule 404(b) evidence (1) “must be relevant to an issue
    other than the defendant’s character,” (2) “there must be sufficient proof” to allow
    a jury to find that the defendant committed the extrinsic act, and (3) the evidence
    “must possess probative value that is not substantially outweighed by its undue
    prejudice, and the evidence must meet the other requirements of Rule 403.”
    United States v. Miller, 
    959 F.2d 1535
    , 1538 (11th Cir. 1992) (en banc).
    Regarding the first element, a not-guilty plea to a conspiracy charge “‘renders the
    defendant’s intent a material issue . . . unless the defendant affirmatively takes the
    issue of intent out of the case.’” United States v. Matthews, 
    431 F.3d 1296
    , 1311
    (11th Cir. 2005) (quoting United States v. Roberts, 
    619 F.2d 379
    , 383 (5th Cir.
    1980)) (internal quotation marks and alterations omitted).
    Furthermore, our precedent holds that “[e]vidence of prior drug dealings is
    highly probative of intent to distribute a controlled substance, as well as
    involvement in a conspiracy.” 
    Matthews, 431 F.3d at 1311
    . Indeed, “virtually any
    35
    prior drug offense [is] probative of the intent to engage in a drug conspiracy.” 
    Id. Because Sanders
    pleaded not guilty to the conspiracy charge, his intent was at
    issue, and the first element was established. The second element was also met
    because Sanders was convicted of the prior act of selling marijuana. Thus, the
    issue for the district court was whether the undue prejudice from the character
    evidence substantially outweighed the probative value of the prior conviction.
    We conclude that the district court abused its discretion by admitting this
    particular 22-year-old, 1.4-gram-marijuana conviction. Although we have
    declined to establish a bright-line rule for when a prior conviction is too old to be
    admissible, Sanders’s 22-year-old conviction is nearly fifty percent older than the
    oldest conviction we have previously allowed. See United States v. Lampley, 
    68 F.3d 1296
    , 1300 (11th Cir. 1995) (holding that a 15-year-old drug conviction was
    not so remote that it lacked any probative value to show the defendant’s intent to
    traffic cocaine). Furthermore, Sanders’s prior conviction was for a street-level
    sale of 1.4 grams of marijuana, and the current charges involved an international
    conspiracy to traffic 153 kilograms of cocaine. Given the factual combination
    here of the lengthy time span, the extremely disparate amounts of different drugs,
    and the materially differing roles in the offenses, we conclude that Sanders’s prior
    conviction had virtually no probative value in establishing Sanders’s intent to
    36
    enter into the present conspiracy. Allowing the government to admit such a
    remote and factually dissimilar conviction would effectively create a per se rule of
    admissibility of any prior drug conviction in drug conspiracy cases—no matter
    how old or how different. Our precedent does not create such a rule, and we
    decline to adopt one today. Because Sanders’s prior 1988 conviction involving
    1.4 grams of marijuana had so little, if any, probative value, the district court
    abused its discretion by admitting the conviction.
    Nevertheless, the paucity of probative value creates an additional problem
    for Sanders—the remoteness and dissimilarity of the prior conviction not only
    decreases the probative value to show intent but also diminishes the potential for
    unfair prejudice. In other words, the prior conviction was so old and dissimilar
    that it is unlikely that the jury convicted Sanders because of the prior conviction,
    either because the jury believed Sanders should still be in jail for the prior
    conviction, or because the conviction demonstrates a propensity to transport large
    quantities of drugs in a tractor–trailer from Texas to North Carolina.
    Given the abundant evidence admitted at trial, we conclude that the district
    court’s admission of the prior conviction was harmless error. As described above,
    Sanders’s co-conspirator Eric Reyes testified that Sanders drove a previous load of
    7,700 pounds of marijuana from Texas to North Carolina. Reyes testified that
    37
    Sanders knew that he was transporting narcotics. Although a truck driver would
    typically charge $3,300.00 for such a trip, Sanders received $9,000.00 and 40
    pounds of marijuana for this trip. Additionally, co-conspirator Aaron Richards
    testified that Sanders planned to take a different route for his second trip because
    he encountered too many cops on the route he took during his last trip.
    The other trial evidence fully corroborated the co-conspirator testimony.
    Importantly, Sanders was arrested while driving a tractor–trailer loaded with 153
    kilograms of cocaine hidden in a pallet of rotten cabbages. Although Sanders
    admitted that he knew that the refrigeration unit on the trailer was broken and that
    he was hauling perishable cabbages, the bill of lading (that Sanders gave the GSP
    officer) showed that Sanders accepted the load on May 4th and was stopped on
    May 7th in Georgia. The trip from Texas to North Carolina typically takes only 18
    to 20 hours—in other words, despite hauling perishable goods with a broken
    refrigeration unit, Sanders had not completed the one-day trip in the three days
    since picking up his load. Furthermore, Sanders had a receipt showing that he had
    maintenance performed on the truck on May 6th—the day before he was
    stopped—but the receipt showed no effort to repair the broken refrigeration unit.
    In sum, although the district court abused its discretion by admitting
    Sanders’s 1988 conviction for selling 1.4 grams of marijuana, the error was
    38
    harmless in light of the overwhelming evidence presented at trial.
    AFFIRMED.
