    Present: Judges Beales, Decker and AtLee
    Argued at Richmond, Virginia
    PUBLISHED
    ANDREW GILBERT SCHMUHL
    OPINION BY
    v.     Record No. 1572-16-4                                 JUDGE RANDOLPH A. BEALES
    SEPTEMBER 11, 2018
    COMMONWEALTH OF VIRGINIA
    FROM THE CIRCUIT COURT OF FAIRFAX COUNTY
    Randy I. Bellows, Judge
    Bradley R. Haywood (Sheldon, Flood & Haywood, PLC; Office of
    the Public Defender, on briefs), for appellant.
    Katherine Quinlan Adelfio, Assistant Attorney General (Mark R.
    Herring, Attorney General, on brief), for appellee.
    A grand jury indicted Andrew Schmuhl (“appellant”) on seven felony counts for acts he
    committed during a home invasion on November 9, 2014. He was charged with two counts of
    abduction with intent to gain pecuniary benefit, two counts of aggravated malicious wounding,
    two counts of using or displaying a firearm during the commission of an aggravated malicious
    wounding, and burglary while armed with a deadly weapon. Appellant filed a pretrial notice of
    his intent to pursue an involuntary intoxication defense. Based upon this theory, appellant
    sought to present evidence of his mental state on the night in question. Specifically, appellant
    intended to show that he was suffering from “a medication induced delirium.” The trial court,
    however, ruled that such evidence was not admissible under appellant’s involuntary intoxication
    defense because appellant did not argue that he was insane. Subsequently, after a more than
    three-week jury trial, appellant was convicted on all seven charges, and he was sentenced to two
    terms of life in prison plus an additional 98 years. Following a timely appeal to this Court, we
    granted six of the twelve assignments of error appellant raised in his petition for appeal.1 We are
    now reviewing the following assignments of error:
    VII.           The trial court erred in finding that Stamper v. Commonwealth
    bars evidence of mens rea unless the defendant presents a
    statutory insanity defense.
    VIII.            The trial court erred in finding that delirium, as well as other
    serious effects of drugs, were insanity defenses, and not
    properly the subject of an involuntary intoxication defense.
    The error derived from application of the wrong standard for
    distinguishing between intoxication and insanity.
    IX.          The trial court erred in circumscribing the manner in which the
    defendant was permitted to prove affirmative defenses, such as
    by excluding expert evidence, redacting records, and barring
    the use of certain words.
    X.          The trial court erred in excluding mental state evidence offered
    in support of an unconsciousness defense.
    XI.          The trial court erred in refusing an unconsciousness jury
    instruction, finding that unconsciousness merged with
    intoxication in this case.
    XII.           The trial court erred in denying an instruction defining
    intoxication.
    For the reasons that follow, we now affirm appellant’s convictions.
    I. BACKGROUND
    A. The Home Invasion
    “Applying familiar principles of appellate review, we will state the facts in the light most
    favorable to the Commonwealth,” as we must, because the Commonwealth was the prevailing
    party in the trial court. Ervin v. Commonwealth, 
    57 Va. App. 495
    , 499, 
    704 S.E.2d 135
    , 137
    (2011) (en banc). So viewed, the evidence established that on the evening of November 9, 2014,
    1
    We have adopted, for the sake of consistency, the numbering convention that appellant
    used in his petition for appeal in listing his assignments of error. We denied appellant’s
    assignments of error I through VI.
    -2-
    Leo Fisher (“Fisher”) was in his McLean, Virginia home with his wife, Susan Duncan
    (“Duncan”). Duncan was preparing dinner when she alerted Fisher that a vehicle had come up
    their driveway. When the doorbell rang, Fisher answered the door. As he opened it, an intruder
    (later determined to be appellant) pushed the door inward and knocked Fisher off balance,
    forcing his way into the home. Appellant used a Taser on Fisher to subdue him. He also then
    bound Fisher’s hands and feet with plastic zip ties.
    Hearing what she described as “some weird noises,” Duncan testified that she went to the
    foyer where she found Fisher lying on the floor. She stated that appellant then came toward her,
    grabbed her, and bound her hands and feet with zip ties. Appellant flashed a badge and
    identified himself as being with the “Virginia SEC.”2 He said he was arresting Fisher because he
    claimed that Fisher had “sent an email placing a hit on a member of the Knights [Templar],” a
    drug cartel, in the amount of $370,000.
    Appellant then forcibly moved the couple to their back bedroom and closed the curtains.
    During the move to the bedroom, Fisher recognized the intruder as Andrew Schmuhl. Fisher had
    met appellant on numerous occasions because appellant’s wife, Alecia Schmuhl, had worked as
    an attorney in the law firm where Fisher was the managing partner.3 Fisher also testified that he
    had fired Alecia Schmuhl for performance-related reasons on October 27, 2014 – approximately
    two weeks prior to the home invasion. However, Fisher did not let appellant know that he
    2
    There is no such government agency in the Commonwealth as the “Virginia SEC,” and
    appellant concedes as much in his opening brief to this Court.
    3
    Fisher testified that he first met appellant at the firm’s holiday party in 2013. Appellant
    had also worked for Fisher’s firm as a contract attorney on a single project. Fisher further
    recalled that in June 2014, appellant and his wife came to Fisher’s office at the law firm to
    discuss an administrative matter. During the meeting, which lasted approximately ten minutes,
    Fisher described appellant’s demeanor as angry and “really aggressive.” Appellant “kept raising
    his voice. His voice kept getting louder and louder.” Fisher testified that he repeatedly had to
    ask appellant to leave his office before appellant ultimately left.
    -3-
    recognized appellant because he did not want to “do anything that would upset him or get him
    angry.”
    In the bedroom, appellant “started interrogating [the couple].” Fisher stated that
    appellant “seemed like he had a set of questions in different topics that he was going to ask us
    about. And to me he seemed to be going through it quite systematically.” Fisher described
    appellant as “acting like a lawyer taking a deposition,” and he indicated that appellant asked
    appropriate follow-up questions.
    Appellant also asked Fisher, “[D]o you know why anybody would’ve put a hit on you?”
    Fisher recounted the specific exchange between him and appellant to the jurors: “I said, I don’t
    know why anybody would do that. And [appellant] said, well, didn’t you let somebody go
    lately? And at first I wasn’t sure what he meant but he -- I realized he was talking about Alecia.
    He never used her name.” Fisher acknowledged that he had recently fired someone, and, despite
    the fact that no one had mentioned Alecia’s name, appellant asked, “[W]hy was she let go?”
    When appellant moved the couple from the bedroom to the home office, he closed
    multiple window blinds, which prevented anyone outside the home from observing the events
    inside. Appellant told the couple that “there might be a sniper” outside.
    Both Fisher and Duncan testified that appellant communicated with a third person during
    the course of the home invasion. Duncan testified, “Once I saw him out in the foyer . . . . He
    was flipping [the outdoor lights] on and off signaling somebody.” Another time, Duncan
    observed that appellant “had th[e] door wide open and he was standing [t]here and he was talking
    to a woman outside.” Fisher testified that appellant stepped away from the couple to speak on
    the phone at least five times during the home invasion. “[A]fter each call he would say things
    like, I was just talking to my partner. Sometimes he would say I was talking to my boss.”
    Appellant directed Fisher to access and open his office email, which Fisher testified contained
    -4-
    information on the firm’s employees as well as other information valuable to the firm. Appellant
    searched through some of the emails and, according to Fisher’s testimony, became frustrated
    after apparently failing to find the information for which he was looking.
    After appellant moved the couple back to the bedroom, he separated them by placing
    Duncan in the bathroom. Appellant told Duncan that separating them was necessary “because
    there may be things your husband won’t tell me in front of you.” Fisher testified that appellant’s
    questioning then continued on various topics. Appellant asked Fisher whether the couple kept a
    large amount of money in the house. Fisher testified that he thought, “Maybe he wants money.”
    He further testified, “And so I said to him, ‘you know, we don’t have any money here but we can
    go to the bank.’”
    Appellant then attacked Fisher. “[H]e knocked me over, put a pillow over my face and
    cut my throat on the bed.” Appellant also stabbed Fisher in the head and in the left shoulder.
    Fisher screamed to Duncan, “[H]e’s killing me!” Duncan, upon leaving the bathroom, saw
    appellant “on top of Leo and he was cutting his throat.” Appellant yelled, “Get out, ma’am, get
    out now! Don’t come in here, get out!” Duncan testified that she saw appellant raise a gun “[s]o
    I turned my head but I felt the bullet hit me. I fell down on the floor. And then I got up, I felt
    myself getting up and I knew I was alive.” The bullet had grazed Duncan’s head and had lodged
    in the ceiling.
    As Duncan reached for a nearby phone, appellant jumped on her and stabbed her
    repeatedly across her neck, back, and shoulders. Appellant only ceased his attacks when Duncan
    pretended to be dead. As appellant left the room, Fisher testified, “I was on the floor and he
    came past me and he kicked me in the head . . . . [H]e said, ‘You’re going to die.’”
    Duncan hit the panic button on the home’s security system, thereby activating an audible
    alarm. As she went to call 911, she saw appellant in the front foyer as he left the house. After
    -5-
    the police arrived, multiple officers noticed the odor of gas, and it was later determined that
    gasoline had been poured on the rug in the foyer. No gasoline was on the rug prior to that
    evening.
    Fisher and Duncan were able to observe appellant’s demeanor while he was in their home
    for approximately three hours. Duncan characterized appellant as “very forceful, authoritative.
    Very much in control.” Even though appellant argued that he was overmedicated, and, thus,
    involuntarily intoxicated, Duncan testified that appellant did not stumble or slur his speech.
    Fisher likewise testified that appellant did not slur his speech at any point during the home
    invasion.
    B. Pursuit and Arrest of Appellant
    The first police officers to arrive at the home found Fisher on the front porch. Fisher was
    bleeding severely from his neck, and Officer Joseph Shifflett testified that he had to stuff his
    hands inside the wounds in Fisher’s neck to slow the bleeding. Despite the severity of his
    wounds, Fisher was conscious and identified appellant as his attacker. A “flash message” was
    then sent to police units to be on the lookout for appellant’s vehicle.
    Officer Daniel Custard testified that, approximately ten minutes later, he identified
    appellant’s vehicle, which was traveling on Interstate 495. The officer stated that he activated
    his vehicle’s lights and siren, but appellant’s vehicle refused to pull over. Officer Custard
    pursued the vehicle and could see two individuals inside it. Custard testified that he “observed
    the passenger in the vehicle reaching all over the vehicle, [he] appeared to be reaching under the
    seat and removing his clothing.”
    After appellant’s vehicle finally stopped, police took the driver, Alecia Schmuhl, into
    custody. Appellant exited the vehicle, “wearing only an adult diaper.” Officer Custard ordered
    appellant to the ground, and appellant was responsive to the officer’s commands. He then
    -6-
    handcuffed appellant and placed him in the back of the police vehicle. After a brief period of
    time, Custard returned to that police vehicle and observed a change in appellant’s condition. He
    testified, “I noticed that there was a pretty distinct change in his level of consciousness. When I
    first spoke to him, he was very lucid, he was able to answer questions easily . . . . [W]hen I
    returned to him he appeared to be almost passing out.” Officer Custard further stated that
    appellant’s eyes were “in the back of his head” and that he “had an altered level of
    consciousness.” Custard asked appellant if he had taken anything illegal or any medications, and
    appellant told Custard that he had taken Dilaudid and fentanyl.
    Officer Daniel Curcio observed appellant’s demeanor after his arrest and at the hospital.
    While appellant sat in the back of the police vehicle, Officer Curcio noticed that “he was a little
    lethargic . . . . He seemed like he was kind of dazed, a little in and out.” Officer Curcio also
    testified that appellant briefly spoke to him in German. Based upon appellant’s condition,
    Curcio asked appellant’s wife, who was in a different police vehicle, if appellant had taken any
    medication. She informed him that appellant had an implant for a back injury. Curcio testified
    that he believed EMTs on the scene also removed a fentanyl patch from appellant’s upper left
    arm. Later, at the hospital, medical personnel also removed a second fentanyl patch, which was
    hidden beneath appellant’s adult diaper. Officer Curcio also heard appellant tell medical staff
    that “he had taken a handful of a muscle relaxer,” called Tizanidine.
    C. Evidence Recovered from Appellant’s Vehicle
    Officer Matthew Keisling testified at trial regarding the physical evidence found in
    appellant’s vehicle. Police recovered various pieces of clothing – some of which appeared to be
    stained with blood. The clothing was wet and smelled strongly of ammonia, and Officer
    Keisling testified that the odor of ammonia in the vehicle was overwhelming. Police also
    -7-
    recovered a soda bottle that contained a small amount of liquid that smelled strongly of
    ammonia.
    In the vehicle’s center console, police recovered a pill bottle labeled “Tizanidine HCl” –
    the same muscle relaxer that appellant told officers he had “taken a handful of.” They also
    recovered Alecia Schmuhl’s purse, which contained a list written in appellant’s handwriting,
    according to a handwriting expert who testified for the Commonwealth. The list stated:
    “handcuffs, two bottles of Nyquil, two packs of Benadryl, adult diapers (male), two sleeping
    masks (if available).”
    In a shopping bag, police found a disassembled handgun and five cartridges – one of
    which had already been fired. They also found a backpack that contained numerous items,
    including handcuffs, rubber gloves, a blood-stained knife, a package of zip ties, a box of
    Benadryl, two bottles of Nyquil, and a dark jacket. Inside the jacket were numerous items,
    including a Taser, Taser cartridges (two of which had been fired, as evidenced by the exposed
    wires and Taser darts), and a piece of tape that had been used to collect the anti-felon
    identification devices (AFIDS) that a Taser releases when fired. Officer Keisling further testified
    that no cartridges were found in the couple’s home.
    Police also recovered two prepaid cell phones from the vehicle, one of which had its
    battery removed and its SIM card broken in half.4 The phones were activated on November 7,
    2014 – two days before the home invasion. On November 9, 2014, numerous calls were made
    between the two prepaid phones during the time that appellant was in the victims’ home. One of
    4
    Officer Brian Bayliss, a member of the Fairfax County computer forensic section,
    testified that “SIM” stands for “subscriber identity module” and that a cell phone’s SIM card
    “identifies the person that has the actual subscription or the account that is billed.” Officer
    Bayliss also testified that “a prepaid phone is very cheap and it can be paid for . . . with cash, and
    since it’s paid with cash, it’s very difficult to trace back to an actual account holder or
    subscriber.”
    -8-
    the prepaid phones was physically in the vicinity of the victims’ home between 6:33 p.m. and
    9:46 p.m. After appellant and his wife were taken into custody, police searched their home and
    recovered their regular personal cell phones. Thus, neither appellant nor his wife were actually
    carrying their personal cell phones at the time of their arrest on November 9, 2016, as they had
    left them at home.
    D. Pretrial Hearings on the Admissibility of Expert Witness Testimony
    Before trial, on November 20, 2015, defense counsel filed a notice which stated:
    Andrew Schmuhl intends to assert at trial that his mental state at
    the time of the offense met the legal standard for insanity, and [he]
    intends to present evidence, including expert testimony, in support
    of this defense. His mental state at the time of the offense resulted
    from the use of medication.
    The Commonwealth then filed motions to conduct its own evaluation of appellant’s mental
    health and to review the report prepared by appellant’s mental health expert. Appellant opposed
    the Commonwealth’s motions, arguing that the provisions of Code § 19.2-168.1 and
    § 19.2-169.5 did not apply to an involuntary intoxication defense. On November 30, 2015, the
    trial court conducted a hearing on the Commonwealth’s motions and asked defense counsel to
    clarify his position on whether appellant was asserting an insanity defense, which entitled the
    Commonwealth to the motioned-for discovery. The trial judge stated:
    I think you have to elect either you have given the Court an
    insanity notice . . . and I will treat it as such and proceed from there
    or you tell me it’s not an insanity notice even though when I read it
    I thought it was, but if you tell me it’s not, I believe I have to
    accept your representation because you get to choose.
    Defense counsel confirmed, “It’s an involuntary intoxication notice . . . not an insanity notice,”
    and based upon this representation, the trial judge denied the Commonwealth’s motions.
    On December 23, 2015, the trial court conducted a second hearing to determine whether
    expert testimony about appellant’s mental state would be admissible at trial. Prior to this
    -9-
    hearing, the trial judge submitted questions to defense counsel to assist the court in resolving the
    question of admissibility.5 However, defense counsel declined to answer these questions and
    argued that his client could not be compelled to disclose trial strategy. The judge specifically
    inquired if defense counsel was willing to resolve the issue of expert witness testimony prior to
    trial. The trial judge stated:
    [I]s it your position that this . . . ought not happen until we’re in the
    middle of trial after opening statement; after you have made
    representation[s] presumably to the jury about what they are going
    to hear. That at that point and only at that point will this Court be
    able to make a ruling on the specifics of an expert testimony?
    Defense counsel subsequently acknowledged on the record that he understood the risk of not
    resolving the issue before trial. Defense counsel stated:
    [W]e’ll have to take the time out maybe it’s a two hour hearing . . .
    in the middle of trial to determine at that point whether the expert
    can testify [to] what we want them to testify to. If it’s excluded . . .
    we are taking that risk.
    Ultimately, the trial court asked whether defense counsel was “unwilling to make a
    proffer as to the nature of . . . any expert mental health testimony [that he] wish[ed] to offer prior
    to trial.” Defense counsel stated that he was unwilling to make such a proffer, and he further
    argued that the trial court ran the risk of violating appellant’s constitutional rights if the court
    ordered such a disclosure before trial. As a result, the issue of the admissibility of expert witness
    testimony remained unresolved before trial.
    5
    The record indicates that the trial court submitted questions to defense counsel to
    ascertain “whether you intend to call a mental health expert who will be relying upon any mental
    health records that may exist for Mr. Schmuhl and . . . on interviews conducted by your mental
    health experts with Mr. Schmuhl.” The trial court also sought to determine whether expert
    testimony would be specific to appellant or whether it would be more general in nature.
    - 10 -
    E. The Court’s Rulings During Trial on the Admissibility of Evidence and on Jury Instructions
    On May 27, 2016, during the trial, the trial court conducted a hearing on the admissibility
    of expert witness testimony. During that hearing, defense counsel informed the court about the
    nature of its expert testimony. Defense counsel stated:
    [Appellant] was suffering from . . . a medication induced delirium.
    The diagnostic criteria for delirium include dramatically altered
    mental state that develops over a short period of time, from hours
    to days. It lasts from days to months, but it is temporary and it
    eventually results in full recovery, often quite rapid. It fluctuates
    in severity, meaning it waxes and wanes over the course of the
    days, weeks, months, however long it lasts.
    Defense counsel stated that “the way the law is written, we are sitting on a defense that’s
    premised on temporary insanity,” and he argued that the “expert should be permitted to testify in
    equal degree as one would in an insanity case . . . .”
    Following the hearing, the trial court ruled that appellant could not “offer expert mental
    health testimony in support of its ‘medication-induced delirium’ defense,” because, “[t]he
    concern the Court expressed to defense counsel on December 23rd – that ‘what you’re dealing
    with is in fact an insanity defense that is not called an insanity defense’ – has been realized.”
    However, the trial court expressly stated, “Assuming a proper foundation is laid, this Order does
    not preclude the defendant from calling an expert to address the toxicological effects of ingested
    medications.” On June 1, 2016, defense counsel made an additional proffer that it intended “to
    introduce psychiatric testimony in support of the defense of unconsciousness.” Based on this
    additional proffer, the trial court likewise ruled that appellant was “preclude[d] . . . from offering
    expert mental health testimony on an unconsciousness defense.”
    Pursuant to the court’s decision to permit toxicological testimony but not “psychiatric
    testimony,” the court did not allow appellant’s expert witness to use words like “delirium,”
    - 11 -
    “psychosis,” “dissociation,” and “delusions.” The court also redacted statements relating to
    appellant’s psychiatric history from appellant’s medical records, which were admitted at trial.
    During argument on jury instructions, the court refused appellant’s jury instruction
    defining and describing “unconsciousness,” finding that the instruction on involuntary
    intoxication adequately covered appellant’s defense of unconsciousness. The court also refused
    appellant’s jury instruction defining “intoxication,” which the court found to be a word of
    common usage, and instead permitted the parties to argue the meaning of the word “intoxication”
    before the jury.
    II. ANALYSIS
    A. Standard of Review
    “It is well established that the admissibility of expert testimony is within the sound
    discretion of the trial court, and that court’s decision will not be disturbed absent an abuse of
    discretion.” Patterson v. Commonwealth, 
    3 Va. App. 1
    , 11, 
    348 S.E.2d 285
    , 291 (1986). “Only
    when reasonable jurists could not differ can we say an abuse of discretion has occurred.” Tynes
    v. Commonwealth, 
    49 Va. App. 17
    , 21, 
    635 S.E.2d 688
    , 689 (2006). “However, to the extent the
    trial court makes an error of law in the admission of evidence, ‘an abuse of discretion occurs.’”
    Abney v. Commonwealth, 
    51 Va. App. 337
    , 345, 
    657 S.E.2d 796
    , 800 (2008) (quoting Bass v.
    Commonwealth, 
    31 Va. App. 373
    , 382, 
    523 S.E.2d 534
    , 539 (2000)). “Furthermore, such
    evidentiary issues presenting a ‘question of law’ are ‘reviewed de novo by this Court.’” 
    Id. (quoting Michels
    v. Commonwealth, 
    47 Va. App. 461
    , 465, 
    624 S.E.2d 675
    , 678 (2006)).
    B. The Trial Court’s Interpretation of Stamper
    Appellant argues that the trial court erred when it interpreted the Supreme Court’s
    holding in Stamper v. Commonwealth, 
    228 Va. 707
    , 
    324 S.E.2d 682
    (1985), to bar evidence of
    - 12 -
    mens rea unless a defendant presents an insanity defense. We review assignment of error VII de
    novo. 
    Abney, 51 Va. App. at 345
    , 657 S.E.2d at 800.
    In Stamper, the Supreme Court of Virginia affirmed the trial court’s refusal to allow
    Walter Stamper to introduce evidence that, although he was not insane, he was manic-depressive
    and in a “manic state” on the date that he committed the offense for which he was 
    convicted. 228 Va. at 715-16
    , 324 S.E.2d at 687. Stamper sought to argue that his diminished mental state
    rendered him incapable of forming the intent to distribute, a required element for his conviction.
    
    Id. at 716,
    324 S.E.2d at 687. The Supreme Court rejected Stamper’s argument, declining to
    recognize diminished capacity as a defense in the Commonwealth and further rejecting the
    approach that expert evidence could be used, in the absence of an insanity defense, to show that
    Stamper lacked the necessary mens rea. 
    Id. at 716-17,
    324 S.E.2d at 688.
    The Supreme Court in Stamper expressly held “that evidence of a criminal defendant’s
    mental state at the time of the offense is, in the absence of an insanity defense, irrelevant to the
    issue of guilt.” 
    Id. at 717,
    324 S.E.2d at 688. The Court noted that the fundamental reason for
    the exclusion of this evidence rests on Virginia’s adherence, through the M’Naghten rule, to the
    common law’s use of a “stable and constant standard of mental competence as the criterion for
    the determination of criminal responsibility.” 6 
    Id. at 716,
    324 S.E.2d at 688. Under the common
    law and in the Commonwealth, “[a] person whose mental state falls outside the borderline drawn
    6
    The M’Naghten rule states
    that to establish a defence on the ground of insanity, it must be
    clearly proved that, at the time of the committing of the act, the
    party accused was labouring under such a defect of reason, from
    disease of the mind, as not to know the nature and quality of the
    act he was doing; or, if he did know it, that he did not know he was
    doing what was wrong.
    Price v. Commonwealth, 
    228 Va. 452
    , 457, 
    323 S.E.2d 106
    , 109 (1984) (quoting M’Naghten’s
    Case, 10 Cl. and F. 200, 210, 8 Eng. Rep. 718, 722-23 (1843)).
    - 13 -
    by that standard is deemed legally insane. All persons inside that borderline are ‘presumed to be
    sane, and to possess a sufficient degree of reason to be responsible for [their] crimes.’”

    324 S.E.2d at 688 (quoting Price v. Commonwealth, 
    228 Va. 452
    , 457, 
    323 S.E.2d 106
    ,

    (1843))). In its decision, the Stamper Court emphasized what has always been the case in the
    Commonwealth – i.e., that “there is no sliding scale of insanity.” 
    Id. at 717,
    324 S.E.2d at 688.
    The reasoning behind a bright-line rule separating the sane, who are held criminally responsible,
    and the insane, who are not, is that the “classifications and gradations applied to mental illnesses,
    disorders, and defects” are subject to frequent revision. 
    Id. at 716,
    324 S.E.2d at 688. The
    resolution of each case cannot be “dependent upon these subtle and shifting gradations.” 
    Id. Appellant argues
    that the holding in Stamper is inapplicable to the case at bar because,
    according to appellant, the Supreme Court in Stamper simply reaffirmed that the Commonwealth
    does not recognize the diminished capacity defense and reiterated that the M’Naghten rule
    continues to apply to insanity defenses. He contends that Stamper does not limit evidence of a
    defendant’s mental state when the accused utilizes the defense of involuntary intoxication. We
    disagree for several reasons.
    First, appellant’s argument attempts to ignore the express holding of the Supreme Court
    in Stamper. The Court made clear that the only way to negate mens rea with evidence of a
    defendant’s mental state is to plead an insanity defense.7 The Supreme Court’s holding makes
    no exception for a defense premised on a defendant’s involuntary intoxication. Since Stamper,
    this Court has repeatedly held that evidence of a defendant’s mental state is “immaterial” and
    7
    This holding is subject to the well-recognized exception that a defendant charged with
    premeditated murder may negate his mens rea for the offense with evidence of his mental state at
    the time of the offense – without pleading insanity. Fitzgerald v. Commonwealth, 
    223 Va. 615
    ,
    631, 
    292 S.E.2d 798
    , 807 (1982).
    - 14 -
    “irrelevant” to the issue of mens rea where the defendant failed to put forth an insanity defense.
    Id.; see Peeples v. Commonwealth, 
    30 Va. App. 626
    , 633-34, 
    519 S.E.2d 382
    , 385 (1999) (en
    banc) (citing Stamper and affirming the trial court’s exclusion of expert testimony about the
    defendant’s mental disability, offered to support his defenses of heat of passion and self-defense,
    when he did not allege an insanity defense); Bowling v. Commonwealth, 
    12 Va. App. 166
    ,
    172-73, 
    403 S.E.2d 375
    , 378-79 (1991) (citing Stamper and affirming the trial court’s exclusion
    of expert testimony offered to show that the defendant’s “borderline mental capacity” prevented
    him from forming the intent to distribute narcotics, when he did not allege insanity).
    Second, the defendant who pleads involuntary intoxication still falls squarely within the
    rule set in Stamper because involuntary intoxication is recognized in the Commonwealth as an
    alternative basis for an insanity defense, proven not by showing that the defendant had a
    pre-existing mental disease or defect, but by showing that his involuntary intoxication produced
    a defect in his mens rea that rose to the level of insanity, as set by the M’Naghten rule. In
    Morgan v. Commonwealth, 
    50 Va. App. 120
    , 132-34, 
    646 S.E.2d 899
    , 905-06 (2007), we
    affirmed a trial court’s decision to place both the burdens of production and persuasion on the
    defendant when he pled an “insanity defense of involuntary intoxication.” In Morgan, we
    referred to the alleged defense as “the affirmative defense of insanity,” and this Court approved
    jury instructions that required the defendant to prove “that he was insane due to involuntary
    intoxication.” 
    Id. at 133,
    646 S.E.2d at 905. In Johnson v. Commonwealth, 
    135 Va. 524
    , 
    115 S.E. 673
    (1923), the Supreme Court acknowledged that a defense can be alleged on the basis of a
    defendant’s involuntary intoxication where the intoxication caused either “frenzy” or “madness.”
    Specifically, the Court in Johnson stated, “If, however, a person by the unskillfulness of his
    physician, or by the contrivance of his enemies, eat or drink anything which causes frenzy or
    madness, he is entitled to the same exemption from punishment for his acts thereby occasioned
    - 15 -
    as other madmen.” 
    Id. at 533-34,
    115 S.E. at 676 (emphasis added) (quoting Davis’ Criminal
    Law 29).
    Furthermore, while the Model Jury Instructions in Virginia are certainly not binding
    precedent, we simply note that the Model Jury Instructions in the Commonwealth on involuntary
    intoxication and on insanity support our conclusion that an involuntary intoxication defense
    requires that the defendant prove that he was insane as a result of the involuntary intoxication.
    The Model Jury Instruction on involuntary intoxication largely parallels the instruction for
    insanity, except for the distinction that, with involuntary intoxication, the cause of the
    defendant’s inability to “understand the nature, character and consequences of his act or . . . to
    distinguish right from wrong,” comes from his involuntary intoxication – not his mental disease
    or defect. Compare Model Jury Instrs.—Crim. No. 53.300 (involuntary intoxication), with
    Model Jury Instrs.—Crim. No. 53.150 (insanity).
    In addition, appellant’s argument – that the defense of involuntary intoxication is not
    covered by the rule in Stamper – would, if it were the case, allow a defendant who pleads
    involuntary intoxication to avoid the statutory pleading requirements. The General Assembly
    has given the Commonwealth the statutory right to evaluate a defendant’s mental state – once the
    defendant has given notice of intent to place his sanity at issue. The Commonwealth may
    conduct its own evaluation of the defendant through a different mental health expert appointed
    by the court, and it may review the report created by the defendant’s mental health expert, the
    results of any “evaluation of the defendant’s sanity at the time of the offense,” and copies of
    records “obtained during the course of any such evaluation.” See Code §§ 19.2-168, 19.2-168.1,
    19.2-169.5. A defendant’s failure to properly and timely comply with these statutory
    requirements could result in the defendant’s evidence of his mental state being barred at trial.
    See Code §§ 19.2-168, 19.2-168.1. These statutory procedures – which are not, as appellant
    - 16 -
    describes them, a separate “statutory insanity defense” – reflect the principle that “the
    Commonwealth, like the defendant, is entitled to a fair trial, which includes ‘the right to a fair
    rebuttal of mental health evidence presented by the defendant.’” Grattan v. Commonwealth, 
    278 Va. 602
    , 622, 
    685 S.E.2d 634
    , 645 (2009) (quoting Muhammad v. Commonwealth, 
    269 Va. 451
    ,
    507, 
    619 S.E.2d 16
    , 48 (2005)). Appellant’s argument that he should be permitted to present
    evidence of his mental state because he has labeled his defense as “involuntary intoxication”
    instead of “insanity” would improperly allow appellant to circumvent these statutory
    requirements.
    In short, involuntary intoxication can be another means to prove insanity if the defendant
    can satisfy the M’Naghten rule. In other words, involuntary intoxication only negates mens rea
    if the accused can show that he met the legal standard for insanity – that he did not understand
    the nature, character, and consequences of his act or that he was unable to distinguish right from
    wrong – at the time he committed the offense. The accused may not put forth expert evidence of
    his mental state as to his specific intent, pursuant to an involuntary intoxication defense, unless
    the evidence shows that he passed the legal threshold of insanity due to his involuntary
    intoxication. Therefore, a defendant who pleads involuntary intoxication in this situation must
    comply with the statutory requirements for putting on an insanity defense. Involuntary
    intoxication is not a back-door way for the introduction of expert evidence of a defendant’s
    mental state. This holding is consistent with the common law tradition in the Commonwealth
    that insanity is proven only by meeting the requirements of the M’Naghten rule, consistent with
    the Supreme Court’s holding in Stamper, and consistent with the statutory procedural
    requirements set by the General Assembly.
    By offering expert evidence of his mental state, but refusing to plead insanity, appellant
    attempted to avoid the rules that dictate how such evidence must be disclosed. Appellant
    - 17 -
    essentially wants all the benefits afforded an insanity argument without the associated
    responsibility for notice to the court required by statute and case law. The trial court was correct
    in finding that the Supreme Court in Stamper has precluded the use of evidence of a defendant’s
    mental state to negate mens rea, unless it arises from an insanity defense. Therefore, the trial
    court did not err in finding that, under Stamper, appellant’s expert evidence related to his mental
    state and mens rea was inadmissible because, although appellant pleaded involuntary
    intoxication, he did not plead insanity and did not follow the statutory requirements for putting
    forward an insanity defense.8
    C. The Trial Court’s Finding that Appellant Alleged an Insanity Defense Without the Statutorily
    Required Notice
    In assignment of error VIII, appellant argues that the trial court erred by finding that his
    involuntary intoxication defense amounted to an insanity defense. He argues that his
    “medication induced delirium” did not amount to insanity because it resulted from his
    medication, and it “resolved immediately after the medications were eliminated or neutralized.”
    8
    In addition, appellant’s argument that the trial court’s reading of Stamper conflicts with
    existing precedent is easily dismissed. In Fitzgerald v. Commonwealth, the accused was
    permitted to offer expert testimony on his intoxicated mental state, pursuant to the exception that
    a defendant, who committed murder while voluntarily intoxicated, may negate his mens rea for
    capital murder without pleading 
    insanity. 223 Va. at 624-25
    , 292 S.E.2d at 803. This exception
    applies “when a person voluntarily becomes so intoxicated that he is incapable of deliberation or
    premeditation, he cannot commit a class of murder that requires proof of a deliberate and
    premeditated killing.” Wright v. Commonwealth, 
    234 Va. 627
    , 629, 
    363 S.E.2d 711
    , 712 (1988).
    Because appellant in this case was not charged with premeditated murder, the exception is
    inapplicable here. Likewise, Pritchett v. Commonwealth, 
    263 Va. 182
    , 
    557 S.E.2d 205
    (2002), is
    also unpersuasive here. In Pritchett, the Supreme Court held that the trial court erred in
    excluding expert testimony as to the hypothetical effect of the defendant’s mental disorder on the
    reliability of his confession in a police interview – not as to his mens rea actually to commit the
    underlying crime. 
    Id. at 187,
    557 S.E.2d at 208. The Court in Pritchett did not consider expert
    evidence of the defendant’s mental state as to his specific intent to commit the crime. Therefore,
    neither the Supreme Court’s holding in Fitzgerald nor in Pritchett contradicts its clear holding in
    Stamper, and neither is applicable to the case now before us.
    - 18 -
    Despite the numerous assertions by appellant’s counsel that appellant was not pleading an
    affirmative defense of insanity, appellant’s counsel stated during his proffer on May 27, 2016:
    “this is, in essence, it’s a claim of insanity, a claim of temporary insanity.” Counsel for appellant
    maintained, however, that the defense was not “the insanity defense according to statute.” The
    prosecutor argued, during the May 27, 2016 hearing, that appellant’s defense was premised not
    on intoxication but on a mental defect from “medication induced delirium.” Appellant noticed
    his intent to rely on expert testimony regarding a psychiatric evaluation of appellant and certain
    “predisposing and precipitating factors” like “chronic pain, hypertension, stress, sleep
    deprivation, drug dependence, history of neurological disease[,] dehydration, and depression” –
    any combination of which, he argued, could have made appellant more susceptible to the
    delirium.
    Both the proffered evidence and appellant’s assertions demonstrate that appellant was
    attempting to negate mens rea by offering expert evidence of his mental state. Whether
    appellant’s alleged lack of mens rea for the charged offenses resulted from the intoxicating
    substances that he consumed9 or from a mental defect caused by “predisposing and precipitating
    factors,” his argument here is without merit. An accused can completely negate the required
    mens rea for the crimes charged by showing that he met the legal standard for insanity.
    Therefore, the trial court did not err here in concluding that appellant’s claim to lack mens rea
    for the offenses, which he tried to prove in part by the admission of evidence of his mental state,
    was actually an insanity defense. We need not decide for the purposes of this appeal whether his
    defense was premised on a mental defect or on involuntary intoxication. Appellant could have
    9
    Here, the jury, as factfinder, may well have found appellant’s testimony that he was
    involuntarily intoxicated to be incredible, as appellant took the drugs himself and was using at
    least one medication – the fentanyl patches – in a dosage twice as high as his prescription
    allowed.
    - 19 -
    shown a viable defense to negate mens rea by proving insanity, but he failed to do so or even to
    follow the required statutory procedures that would have allowed him to put on such a defense.
    D. The Trial Court’s Exclusion of Evidence of Appellant’s Mental State to Show
    Unconsciousness and Its Limitation of Psychiatric Testimony
    In assignment of error X, appellant argues that “[t]he trial court erred in excluding mental
    state evidence offered in support of an unconsciousness defense.”10 In assignment of error IX,
    appellant argues that “[t]he trial court erred by circumscribing the manner in which the defendant
    was permitted to prove affirmative defenses, such as by excluding expert evidence, redacting
    records, and barring the use of certain words.” Appellant acknowledges that a trial court’s
    decision on the admissibility of evidence is reviewed for an abuse of discretion. See 
    Abney, 51 Va. App. at 345
    , 657 S.E.2d at 800.
    Our Supreme Court has defined “‘unconsciousness’ as a state of mind of persons of
    sound mind suffering from some voluntary or involuntary agency rendering them unaware of
    their acts.” Riley v. Commonwealth, 
    277 Va. 467
    , 479, 
    675 S.E.2d 168
    , 175 (2009) (emphasis
    added) (quoting Greenfield v. Commonwealth, 
    214 Va. 710
    , 714, 
    204 S.E.2d 414
    , 417 (1974)).
    The trial court here refused to admit evidence relating to appellant’s unconsciousness defense
    because it found that the proposed evidence was essentially an effort to put on an insanity
    defense without calling it such so as to show that appellant lacked the necessary mens rea – and
    that appellant was, therefore, directly prohibited from doing so by Stamper.
    10
    We note that the Supreme Court in Riley v. Commonwealth, 
    277 Va. 467
    , 479 n.9, 
    675 S.E.2d 168
    , 175 n.9 (2009) (emphasis added), simply “assume[d], without deciding, that
    unconsciousness is a defense to criminal charges other than just homicide” when it affirmed the
    convictions for driving while intoxicated and maiming another person as a result of driving while
    intoxicated. The Supreme Court has not actually decided that unconsciousness is a defense to
    criminal charges not involving homicide.
    - 20 -
    Even assuming without deciding that the trial court erred in excluding this evidence, any
    error was harmless.11 Appellant argues that the trial court abused its discretion by essentially
    rendering the defense of unconsciousness unavailable to Schmuhl. As appellant raises a
    challenge related to the admissibility of evidence, “[w]e examine this claim under the standard
    for non-constitutional harmless error.” Salahuddin v. Commonwealth, 
    67 Va. App. 190
    , 211-12,
    
    795 S.E.2d 472
    , 483 (2017); see Carter v. Commonwealth, 
    293 Va. 537
    , 544-46, 
    800 S.E.2d 498
    ,
    501-02 (2017) (applying a non-constitutional standard to determine that any error was harmless
    that the trial court committed in refusing to admit certain evidence supporting a defendant’s
    claim of self-defense).
    The standard for non-constitutional error is established in Code § 8.01-678, which
    provides, in pertinent part:
    When it plainly appears from the record and the evidence given at
    the trial that the parties have had a fair trial on the merits and
    substantial justice has been reached, no judgment shall be arrested
    or reversed . . . [f]or any . . . defect, imperfection, or omission in
    the record, or for any error committed on the trial.
    Error is harmless when we are able to conclude “with fair assurance, after pondering all that
    happened without stripping the erroneous action from the whole, that the judgment was not
    substantially swayed by the error.” Clay v. Commonwealth, 
    262 Va. 253
    , 260, 
    546 S.E.2d 728
    ,
    731-32 (2001) (quoting Kotteakos v. United States, 
    328 U.S. 750
    , 764-65 (1946)). “[H]armless
    error analysis . . . [is not] simply a sufficiency of the evidence analysis.” Hooker v.
    Commonwealth, 
    14 Va. App. 454
    , 458, 
    418 S.E.2d 343
    , 345 (1992), quoted with approval in
    Williams v. Commonwealth, 
    32 Va. App. 395

    528 S.E.2d 166
    , 169 (2000) (en banc); see
    11
    Because we find that appellant’s arguments that relate to evidence offered in support of
    his unconsciousness defense are adequately resolved with a harmless error analysis, we decline
    to consider the issue on the merits, following the principle that “an appellate court decides cases
    ‘on the best and narrowest ground available.’” Luginbyhl v. Commonwealth, 
    48 Va. App. 58

    , 77 (2006) (en banc).

    219 Va. 516
    , 519, 
    248 S.E.2d 784
    , 786 (1978). The appellate court
    must “examin[e] the excluded evidence in light of the entire record.” Commonwealth v. Proffitt,
    
    292 Va. 626
    , 642, 
    792 S.E.2d 3
    , 11 (2016).
    The record reflects that appellant was not unconscious during the attack. It shows he
    planned and completed the home invasion with precision, clarity, and control. Appellant
    handwrote a shopping list ahead of the attack with the items he needed: “handcuffs, two bottles
    of Nyquil, two packs of Benadryl, adult diapers (male), two sleeping masks (if available).”
    Appellant disguised himself, forced his way into the house, and attempted to maintain a fake
    identity during the entire encounter. Testimony from Fisher and Duncan revealed that appellant
    did not stumble and did not slur his words during the three hours that he was inside their home.
    He questioned the couple extensively and demanded information about money that they might
    keep in the house. He also looked through Fisher’s work email – apparently not finding the
    information for which he searched. Appellant forced the victims to move from room to room
    throughout the invasion, and he closed window blinds in the house. Appellant shot and stabbed
    Duncan, he tasered and stabbed Fisher, and he then kicked the already gravely wounded Fisher
    in the head as he left, telling him, “You’re going to die.” Evidence showed that appellant
    attempted to cover up his crimes by recovering the Taser cartridges and gun shell casings and
    that he doused the foyer rug with gasoline before leaving the home. Appellant used a prepaid
    phone during the events rather than his personal cell phone, removed his bloody clothing prior to
    arrest, and soaked the clothing in ammonia as he and his wife fled from the police. Fisher later
    described appellant’s demeanor during the events as “very forceful, authoritative. Very much in
    control.” In addition, testimony from arresting officers showed that appellant was alert when he
    was first apprehended – and that any change in his level of consciousness took place after he was
    placed into the police vehicle. Any possible error in not admitting expert evidence of his mental
    - 22 -
    state at the time of the offenses is simply insignificant in comparison with the overwhelming
    evidence of appellant’s lucidity both before and during the events in question.12
    In assignment of error IX, appellant argues that the trial court erred by limiting
    appellant’s presentation of evidence in support of his proffered defenses of involuntary
    intoxication and unconsciousness. The trial court redacted medical records, limited appellant’s
    expert testimony to a discussion of toxicology rather than psychiatry, and would not allow
    appellant’s expert to use certain words like “delirium,” “psychosis,” “dissociation,” and
    “delusions.” Because appellant refused to plead insanity, the trial court did not err in preventing
    appellant from presenting expert testimony about his mental state. In addition, the trial court has
    broad discretion in deciding what evidence is relevant and should be admitted at trial. Therefore,
    we cannot find that it was an abuse of discretion for the trial court to limit the use of certain
    words and to redact medical records because the trial court did so to prevent appellant from
    presenting expert evidence of his mental state without first making an insanity defense, as
    required by statute and by the Supreme Court’s holding in Stamper. Furthermore, even assuming
    without deciding that it was error to exclude any such evidence related to appellant’s
    unconsciousness defense, any error was harmless for the reasons we have stated above.
    E. Jury Instructions on Unconsciousness and Intoxication
    “The purpose of any jury instruction is to inform the jury of the law guiding their
    deliberations and verdict.” 
    Morgan, 50 Va. App. at 132
    , 646 S.E.2d at 905 (quoting Keen v.
    12
    Even if appellant, as he claims, was actually wearing two fentanyl patches at the time
    of the home invasion that he committed here, these two fentanyl patches were twice his
    prescribed dosage. The Supreme Court has stated, “Where not self-induced, unconsciousness is
    a complete defense to a criminal homicide.” 
    Riley, 277 Va. at 479
    , 675 S.E.2d at 175 (quoting
    
    Greenfield, 214 Va. at 714
    , 204 S.E.2d at 417). However, given the extraordinary amount of
    fentanyl that appellant claims was on him at the time of the offenses (and the fact that the amount
    far exceeded his prescribed dosage), the defense of unconsciousness would simply not be
    available to appellant, even if he had been unconscious (which the evidence shows he was not),
    because any supposed unconsciousness would have been self-induced.

    In his last two assignments of error (assignments of error XI and XII), appellant claims
    that the trial court erred by denying his requested jury instruction that defined and described
    “unconsciousness” and his jury instruction that defined “intoxication.” Appellant’s proposed
    instruction on unconsciousness stated:
    Unconsciousness refers to a state where a subject physically acts in
    fact but is not, at the time, conscious of acting. Unconsciousness
    does not reach the physical dimensions commonly associated with
    the term (coma, inertia, incapability of locomotion or manual
    action, and so on) in order to represent a legal defense. If you find
    that Mr. Schmuhl was physically acting but not conscious of his
    acts at the time of the offense, you must find him not guilty.

    Appellant argues that his defense of unconsciousness was not adequately addressed by the
    instruction that the court gave on involuntary intoxication, and he claims that he offered more
    than a “scintilla of evidence” to justify a separate unconsciousness instruction. See Gibson v.
    Commonwealth, 
    216 Va. 412
    , 417, 
    219 S.E.2d 845
    , 849 (1975) (stating that jury instructions
    “must be supported by more than a mere scintilla of evidence”).
    However, appellant’s requested instruction on unconsciousness was an inaccurate
    statement of the law. For example, it did not indicate that unconsciousness cannot be
    self-induced by voluntarily taking drugs or medication. See 
    Riley, 277 Va. at 479
    , 675 S.E.2d at
    175. The instruction also failed to state that unconsciousness is caused by “some voluntary or
    involuntary agency rendering [persons] unaware of their acts.” 
    Id. Therefore, the
    trial court did
    not err in refusing appellant’s requested jury instruction on unconsciousness because it was
    inaccurate.
    Finally, appellant contends that the trial court erred when it refused his instruction that
    stated, “Legal intoxication means a disturbance of mental or physical capacities resulting from
    the introduction of substances into the body.” The Supreme Court has held that “[t]he phrase
    ‘under the influence of intoxicants’ is composed of words of ordinary significance and their
    meaning is well known to the average juror, but in the absence of statute the phrase is not
    susceptible of a definite, accurate definition acceptable to all.” Gardner v. Commonwealth, 
    195 Va. 945
    , 953, 
    81 S.E.2d 614
    , 619 (1954). There is neither a model jury instruction nor a statute
    defining the word “intoxication” in the Commonwealth. Therefore, we cannot say that the trial
    court abused its discretion in refusing to give an instruction on the definition of “intoxication”
    and in instead permitting the parties to argue the meaning of “intoxication” before the jury.

    III. CONCLUSION
    In short, the trial court did not err in excluding the evidence of appellant’s mental state
    pursuant to his involuntary intoxication defense or in circumscribing the manner in which
    appellant presented his evidence of the effects of the drugs he took. The Commonwealth’s
    common law history as a M’Naghten jurisdiction and the Supreme Court’s holding in Stamper
    prevent evidence of a defendant’s mental state from being offered to negate mens rea for an
    involuntary intoxication defense, unless the defendant properly notifies the Court, as required by
    statute, that his involuntary intoxication caused him to cross the legal threshold to insanity at the
    time he committed the offense. Furthermore, it was not error for the trial court to find that
    appellant was actually offering an insanity defense, despite not following the required statutory
    procedures for doing so under Code §§ 19.2-168, 19.2-168.1, and 19.2-169.5 and despite
    appellant’s protests to the contrary, when appellant intended to rely on expert evidence to show
    his mental state at the time he committed the charged offenses. In addition, assuming without
    deciding that it was error to exclude appellant’s evidence of his mental state for his
    unconsciousness defense, any error was harmless given the overwhelming evidence of
    appellant’s guilt and the overwhelming evidence that he was not unconscious when he
    committed these offenses. It was not error to exclude appellant’s proposed jury instruction on
    “unconsciousness” because the instruction on unconsciousness was an inaccurate statement of
    the law. Finally, the trial court did not abuse its discretion in excluding appellant’s proposed jury
    instruction on the word “intoxication” (and in simply allowing both counsel to argue the meaning
    of the word before the jury) because “intoxication” is a word of common usage and there is
    neither a model jury instruction nor a statute defining the term.
    For all of these reasons, we affirm appellant’s convictions for two counts of abduction
    with intent to gain pecuniary benefit, two counts of aggravated malicious wounding, two counts
    - 26 -
    of using or displaying a firearm during the commission of an aggravated malicious wounding,
    and burglary while armed with a deadly weapon.
    Affirmed.
