DENNIS WAYNE KURTS,
Before: Cooper, P.J., and Jansen and Hoekstra, JJ.
In these consolidated appeals, the prosecution appeals by leave granted1 two trial court
orders ruling that “carboxy THC”2 is not a schedule 1 controlled substance under MCL
In Docket No. 258346, this Court granted the prosecution’s motion to file an interlocutory
appeal and stayed the trial court proceedings. People v Derror, unpublished order of the Court
of Appeals, entered October 21, 2004 (Docket No. 258346). In Docket No. 259315, this Court
granted the prosecution’s motion to file an interlocutory appeal after one count—violation of
MCL 257.625(8)—was dismissed before trial. Defendant proceeded to trial on the remaining
counts. People v Kurts, unpublished order of the Court of Appeals, entered December 27, 2004
(Docket No. 259315).
Carboxy THC is known by many names and was also referred to as “11 Carboxy THC” and
“11-COOH-THC” in the lower court proceedings.
333.7212(1)(d) for purposes of punishing violations of MCL 257.625(8), which prohibits the
operation of a motor vehicle with any amount of a schedule 1 controlled substance in the body.
In Docket No. 258346, the prosecution also appeals a trial court order ruling that, pursuant to
MCL 257.625(4) and MCL 257.625(5), the prosecution must prove that the presence of a
controlled substance in a defendant’s body is a proximate cause of an accident resulting in death
or serious injury. In Docket No. 259315, the prosecution appeals the dismissal of the charges
against defendant, Dennis Wayne Kurts, based on the insufficiency of the evidence.
We agree with the trial courts’ determinations that carboxy THC is not a schedule 1
controlled substance. However, we disagree with the trial court in Docket No. 259315 that the
presence of this substance in a defendant’s blood is not evidence of the presence of THC,3 a
schedule 1 controlled substance. In Docket No. 258346, we agree with the trial court’s
determination that the prosecution must prove beyond a reasonable doubt that the presence of a
controlled substance in a defendant’s body was a proximate cause of the accident. Accordingly,
we affirm the trial court’s orders in Docket No. 258346, and reverse the trial court’s order
dismissing the case against Mr. Kurts in Docket No. 259315. We, therefore, remand in that case
for further proceedings consistent with this opinion.
I. Facts and Procedural History
In Docket No. 258346, defendant Delores Marie Derror was charged with violating MCL
257.625(8) for driving under the influence of marijuana, a schedule 1 controlled substance, and
with violating MCL 257.625(4) and MCL 257.625(5) for causing a motor vehicle accident
resulting in death and serious injury. Ms. Derror was driving eastbound on a snow and slushcovered M-72 at approximately 6:00 p.m. on a snowy January 11, 2004, when she crossed into
oncoming traffic and collided with another vehicle. The front-seat passenger was killed, two
children riding in the back seat were paralyzed, and a third child received a broken neck and jaw.
Deputy sheriffs found five marijuana cigarettes in Ms. Derror’s purse while looking for
identification. Ms. Derror later admitted that she had smoked one marijuana cigarette at 2:00
p.m. Two separate blood samples were analyzed for the presence of illegal substances. The first
blood sample drawn contained thirty-eight nanograms per milliliter of carboxy THC, and the
second contained thirty-one nanograms per milliliter of the same substance.
In Docket No. 259315, Mr. Kurts was also charged with operating a motor vehicle under
the influence of marijuana in violation of MCL 257.625(8). Mr. Kurts was stopped at
approximately 9:45 p.m. on February 25, 2004, for driving erratically. The officer initiating that
stop noted the Mr. Kurts smelled of alcohol and that his eyes were glassy and bloodshot. Mr.
Kurts admitted to drinking two beers and was asked to exit the vehicle. After the officer
discovered a marijuana pipe in Mr. Kurts’ pocket during a pat-down search, Mr. Kurts admitted
THC, or tetrahydrocannabinol, is the psychoactive ingredient of marijuana. People v Sinclair,

NW2d 491 (1975).
to smoking marijuana only a half-hour earlier.4 Mr. Kurts’ blood contained eight nanograms per
milliliter of carboxy THC, and .07 grams of alcohol per 100 milliliters.
In each case, both the prosecution and defense presented the testimony of expert
witnesses at pretrial evidentiary hearings regarding the characteristics of marijuana, THC, and
carboxy THC. The experts agreed that carboxy THC is a “metabolite,” or byproduct of
metabolism,5 created in the human body during the body’s biological process of converting
marijuana into a water-soluble form that can be excreted more easily. Its presence in the blood
conclusively proves that a person ingested THC at some point in time. However, carboxy THC
itself has no pharmacological effect on the body and its level in the blood correlates poorly, if at
all, to an individual’s level of THC-related impairment. In fact, carboxy THC could remain in
the blood long after all THC was gone, as THC quickly leaves the blood and enters the body’s
In Docket No. 258346, the trial court determined, following a pretrial evidentiary
hearing, that the Legislature did not intend to include carboxy THC as a schedule 1 controlled
substance because it has no pharmacological effect on the human body. The court did not
dismiss the case against Ms. Derror, however, because a jury could determine from the presence
of this substance in her blood that she had THC in her body at the time of the accident. Although
the prosecution argued that MCL 257.625(8) is a strict liability statute, the court ordered that the
prosecution would be required to establish at trial that the presence of the THC in Ms. Derror’s
blood was a proximate cause of the accident for purposes of MCL 257.625(4) and MCL
In Docket No. 259315, the trial court granted Mr. Kurts’ motion to dismiss his charged
violation of MCL 257.625(8). Following an evidentiary hearing, the court determined that the
Legislature did not intend to include carboxy THC as a schedule 1 controlled substance because
it has no pharmacological effect or medicinal value. As the level of carboxy THC in a person’s
blood bears a poor correlation to the level of THC in a person’s body, the court found that there
was insufficient evidence for a jury to find that Mr. Kurts was operating a motor vehicle with a
controlled substance in his body at the time of his traffic stop. These appeals followed.
II. Nature of Carboxy THC
This case presents an issue of first impression—whether carboxy THC, a metabolite of a
schedule 1 controlled substance, can be considered a schedule 1 controlled substance itself for
The officer also found a baggie containing “suspected” marijuana.
See People v Hardy, 188 Mich App 305, 307 n 1; 469 NW2d 50 (1991), mod 471 NW2d 619
The prosecution’s expert witness in Docket No. 259315, Dr. Felix Adatsi, testified more
specifically that the presence of carboxy THC in the blood indicates marijuana use within the last
twenty-four hours and its presence in the urine indicates use within the last week. The defense
expert witness in Docket No. 258346, Dr. Daniel McCoy, testified that THC leaves the blood
within two hours, but could be found in the body’s tissues even a day later.
purposes of proceeding against a defendant under MCL 257.625(8). Issues of statutory
interpretation are questions of law subject to review de novo on appeal.7 The primary goal in
statutory construction is to ascertain and give effect to the intent of the Legislature.8 It is only
when statutory language is ambiguous that we are permitted to look beyond the statute to
determine the Legislature’s intent.9 When construing an ambiguous statute, “[t]he court must
consider the object of the statute, the harm it is designed to remedy, and apply a reasonable
construction that best accomplishes the statute’s purpose, but should also always use common
sense.”10 In this regard, courts should seek to avoid a construction that would produce absurd
results, injustice, or prejudice to the public interest.11
Defendants were charged with violating MCL 257.625(8), which provides:
A person, whether licensed or not, shall not operate a vehicle upon a
highway . . . within this state if the person has in his or her body any amount of a
controlled substance listed in schedule 1 under section 7212 of the public health
code, 1978 PA 368, MCL 333.7212, or a rule promulgated under that section . . .
Marijuana, spelled “marihuana” in the statute, is expressly included as a schedule 1 controlled
substance in MCL 333.7212(1)(c). This statute does not expressly include carboxy THC, by any
name, as a schedule 1 controlled substance. MCL 333.7212(1)(d) further provides:
Except as provided in subsection (2), synthetic equivalents of the
substances contained in the plant, or in the resinous extractives of cannabis and
synthetic substances, derivatives, and their isomers with similar chemical
structure or pharmacological activity, or both, such as the following, are included
in schedule 1:
(i) ∆1 cis or trans tetrahydrocannabinol, and their optical isomers.
(ii) ∆6 cis or trans tetrahydrocannabinol, and their optical isomers.
(iii) ∆3,4 cis or trans tetrahydrocannabinol, and their optical isomers.
Carboxy THC does have a similar chemical structure to THC.14 However, as carboxy THC is
created during the body’s metabolism of that substance, it clearly is a natural, rather than

synthetic, byproduct of THC.15 Accordingly, we find MCL 333.7212(1)(d) inapplicable and
must determine if carboxy THC is included in the definition of marijuana as a classified schedule
1 controlled substance.
Marijuana is defined as “all parts of the plant Canabis Sativa L., growing or not; the seeds
thereof; the resin extracted from any part of the plant; and every compound, manufacture, salt,
derivative, mixture, or preparation of the plant or its seeds or resin.” As a byproduct of the
body’s metabolism of marijuana, carboxy THC is clearly not a part of the actual plant nor does it
fit within the common definitions of a compound, manufacture, salt, mixture, or preparation.16
The Legislature did not define “derivative” in the public health code. The Michigan Supreme
Court has given us permission to use the common dictionary to define terms. However, it is
unnecessary to do so in this case as we can determine the Legislature’s intent by other means.
We note that the Legislature could have included metabolites in the definition of
marijuana or schedule 1 controlled substances if it so intended. Under the probate code, for
example, certain parties are required to report if “a newborn infant has any amount of alcohol, a
controlled substance, or a metabolite of a controlled substance in his or her body.”17 “[T]he
Legislature is presumed to be aware of all existing statutes when enacting new laws.”18 As the
Legislature expressly included metabolites in another statute, we must assume that it intended to
expressly exclude the regulation of these substances in the public health code.19 We also note
that those Arizona and Indiana statutes cited by the prosecution that prohibit the operation of a
motor vehicle under the influence of a controlled substance expressly include metabolites and,
therefore, have no persuasive effect on our interpretation of the relevant statutes in this case.20
We also find that controlling the presence of carboxy THC in a defendant’s body does
not comport with the purpose of the public health code. The general purpose of the code is to
Dr. McCoy testified that innumerous compounds have a similar chemical structure to THC and
yet have no effect on the body. Furthermore, the experts agreed that some metabolites of THC
do have a pharmacological effect on the body, while others, such as carbon dioxide, do not.
The Legislature is presumed to know the rules of grammar and we must, therefore, consider
the placement of the word “synthetic” before each series intentional. See Niles Twp v Berrien
Co Bd of Comm’rs, 261 Mich App 308, 315; 683 NW2d 148 (2004).
It is not contended that carboxy THC could be chemically classified as a salt. Furthermore,
the dictionary definitions of compound, manufacture, mixture, and preparation suggest the
creation of a substance or a combination of elements, rather than the breakdown of one substance
into others as occurs during the metabolic process. See Random House Webster’s Unabridged
Dictionary (2d ed).

protect “the health, safety, and welfare of the people of this state.”21 To meet that goal, the
Legislature provided the administrator with the following guidance in determining how to
classify a substance:
In making a determination regarding a substance, the administrator shall
consider all of the following:
(a) The actual or relative potential for abuse.
(b) The scientific evidence of its pharmacological effect, if known.
(c) The state of current scientific knowledge regarding the substance.
(d) The history and current pattern of abuse.
(e) The scope, duration, and significance of abuse.
(f) The risk to the public health.
(g) The potential of the substance to produce psychic or physiological dependence
(h) Whether the substance is an immediate precursor of a substance already
controlled under this article.
The Legislature further provided that “After considering the factors enumerated in section 7202,
the administrator shall make findings with respect thereto and promulgate a rule controlling the
substance if the administrator finds the substance has a potential for abuse.”23 Furthermore, “The
administrator shall place a substance in schedule 1 if it finds that the substance has high potential
for abuse and has no accepted medical use in treatment in the United States or lacks accepted
safety for use in treatment under medical supervision.”24
It is undisputed that carboxy THC has no pharmacological effect on the human body and,
therefore, it can have no potential for abuse, history of abuse by members of the public, or
produce chemical dependence. It is also undisputed that THC is the precursor of carboxy THC,
and that carboxy THC is not the immediate precursor of any controlled substance. As carboxy
THC itself is a benign substance, it does not meet the criteria for classification as a schedule 1
controlled substance, or for any classification of controlled substance.25 Accordingly, its control
In fact, Dr. Evans testified that carboxy THC can be purchased commercially without a license
from the Drug Enforcement Agency.
could not be the object of the public health code.26 Both the trial courts, therefore, properly
determined that carboxy THC is not a schedule 1 controlled substance.
However, the trial courts reached divergent rulings regarding whether a jury could find
beyond a reasonable doubt that defendants had THC present in their bodies at the time of their
violations from the presence of carboxy THC in their blood. In Docket No. 259315, we find that
the trial court erroneously answered this question in the negative and dismissed the charged
violation of MCL 257.625(8) against Mr. Kurts. We review a trial court’s ruling on a motion to
dismiss charges for an abuse of discretion.27 The evidence presented by the prosecution and
defense expert witnesses reveals that the presence of carboxy THC in a person’s blood
conclusively establishes the prior ingestion of THC. It is irrelevant that Dr. McCoy testified that
the level of THC in Mr. Kurts’ body and related THC-impairment at the time of his traffic stop
could not be determined with certainty, based on the level of carboxy THC in his blood. Mr.
Kurts admitted to smoking marijuana only one half-hour before he was arrested. In light of this
admission and the scientific evidence, although disputed, regarding the significance of the
presence of carboxy THC in the blood, there clearly was sufficient evidence to present this
charge to the jury. Accordingly, the trial court abused its discretion in dismissing this charge
against Mr. Kurts.
In Docket No. 258346, Ms. Derror was also charged with violating MCL 257.625(4) and
MCL 257.625(5), which provide for an enhanced sentence for causing death or serious injury
while driving impaired. These subsections provide in relevant part:
(4) A person, whether licensed or not, who operates a motor vehicle in
violation of subsection (1), (3), or (8) and by the operation of that motor vehicle
causes the death of another person is guilty of a crime . . . .
(5) A person, whether licensed or not, who operates a motor vehicle in
violation of subsection (1), (3), or (8) and by the operation of that motor vehicle
causes a serious impairment of a body function of another person is guilty of a
felony . . . .
The prosecution contends that it need not prove a causal relationship between the presence of the
controlled substance in Ms. Derror’s body and the accident. As MCL 257.625(8) proscribes the
operation of a motor vehicle with any amount of a controlled substance in the operator’s body,
We also note that this Court held that a former statutory section defining marijuana under the
Controlled Substances Act, MCL 335.305(3), included “all forms of marijuana containing the
hallucinogenic or euphoric chemical common in all so so-called species or varieties of the plant.”
Riddle, supra at 437. Carboxy THC is a metabolite of that chemical and, as previously noted,
has no hallucinogenic or euphoric qualities itself.
People v Stephen, 262 Mich App 213, 218; 685 NW2d 309 (2004).
the statute imposes strict liability. Therefore, the prosecution argues that it is not required to
establish impairment causing an accident.
The Michigan Supreme Court held in People v Lardie29 that the Legislature did not
intend to impose strict liability on an individual who “by the operation” of his or her vehicle
while under the influence of alcohol “causes the death of anther person” in violation of MCL
257.625(4).30 The defendant’s voluntary and purposeful operation of the vehicle while under the
influence must have been “a substantial cause of the victim’s death.”31 The statute was
“designed to punish drivers when their drunken driving caused another’s death.”32 Imposing a
penalty on a driver when the fatal accident would have occurred regardless of that intoxication
would, therefore, fail to serve the purpose of the statute.33 We see no reason to interpret the
identical language of MCL 257.625(5) differently. Furthermore, there is no indication in the
plain language of these subsections that the Legislature intended to treat violations of subsection
(8) differently than violations of subsections (1) or (3). Accordingly, the trial court properly
determined that the prosecution must prove that the presence of a controlled substance in Ms.
Derror’s body was a proximate cause of the accident.
We note that the Michigan Supreme Court will revisit its decision in Lardie in the very
near future. The Court granted leave to appeal in People v Schaefer34 and People v Large.35 The
Court will consider:
(1) whether the “substantial” cause language in People v Lardie . . . is consistent
with the statute; (2) whether MCL 257.625(4)’s requirement that the prosecutor
establish that the defendant’s “operation of that motor vehicle causes the death of
another person” requires the prosecutor to establish that the defendant’s operation
of the motor vehicle was affected by his intoxicated state; (3) whether the statute
obligates the prosecutor to show that the defendant’s driving at the time of the
accident was a proximate cause of another person’s death; (4) whether it is
sufficient that the prosecutor establish only that the defendant decided to drive
while intoxicated, and that a death resulted; and (5) if so, whether the statute
violates the equal protection clause of the Michigan Constitution, Const 1963, art
1, § 2, or the equal protection clause of the federal Constitution, US Const, Am
XIV, or is otherwise unconstitutional.

However, “[a] decision of the Supreme Court is binding upon this Court until the Supreme Court
overrules itself.”37 The Supreme Court has yet to do so and we remain bound by Lardie.
We affirm in Docket No. 258346. In Docket No. 259315, we affirm the trial court’s
determination that carboxy THC is not a schedule 1 controlled substance. However, we reverse
the court’s dismissal of the charged violation of MCL 257.625(8) against Mr. Kurts based on its
erroneous determination that the presence of this substance in his body was not evidence of the
presence of a schedule 1 controlled substance in his body at the time of the alleged violation.
We, therefore, remand for further proceedings consistent with this opinion. We do not retain
