OPINION
Dеfendant appeals his conviction for possession of a controlled substance, a class B misdemeanor, in violation of what is now Utah Code Ann. § 58-37-8(2)(a)(i) (Supp. 1993). Defendant’s primary contention is that the investigatory stop, which culminated in his arrest, was unlawful. We affirm.
FACTS
On the afternoon of September 28, 1991, Officer Ingrid Weinmuller, a Provo City police officer, was assigned traffic control duty following a university football game. While waiting for the game to end, she monitored traffic from her private, unmarked vehicle. Her automobile was stationed in an empty parking lot facing east. Officer Weinmuller was attired in her police uniform.
At approximately 3:30 p.m., a red truck carrying two males pulled into the parking lot and stopped directly in front of Officer Weinmuller’s vehicle. The truck was situated approximately ten feet from Officer Weinmuller and faced north. Despite being a rather warm day, the windows of the truck were rolled up. The officer saw the driver taking some “hits” from a small cigarette which appeared to her to be a “joint.” The officer could see that the cigarette was smaller than a manufactured cigarette and that it had the distinctive shape оf a joint. Officer Weinmuller saw the orange glow of the cigarette as defendant, the driver, inhaled, and she could see the paper quickly disintegrate in a manner which her experience 1 told her was typical of marijuana cigarettes.
Officer Weinmuller then exited her vehicle and, with an outstretched hand, stopped the defendant as he started to drive away. She observed that he looked surprised as he saw her in uniform. Defendаnt opened the door and Officer Weinmuller immediately smelled the odor of marijuana emanating from defendant while she saw him exhale smoke from his mouth. She was approximately three feet from defendant at this point. The officer then asked defendant to exit his vehicle. Officer Weinmul- *439 ler testified that defendant’s speech was slow and his eyes were very bloodshot.
During the stop, Officer Weinmuller asked defendant where he had put the marijuana cigarette she had seen him smoking and he replied that he had given it to his friend who had exited the vehicle earlier. She then asked how many hits he had taken and he admitted to having taken “a few.” Finally, she told defendant that it was illegal to operate a vehicle while impaired by marijuana, and he replied that he would not be driving if “it” was going to affect his driving.
Defendant was then placed under arrest. A consent search of defendant’s vehicle revealed neither the remnant of the joint nor any controlled substance.
At trial, which was to the court sitting without a jury, Officer Weinmuller testified to the facts set forth above. Defendant did not testify, except as to an ancillary matter. See note 3. On cross-examination, the officer аdmitted she did not know whether a hand-rolled tobacco cigarette would burn in a way significantly different from a marijuana joint. The officer also had understandable difficulty explaining in verbal terms the specific differences between the smell of tobacco and the smell of marijuana, but on redirect stated that she did know, and could readily discern in practice, the difference between the two aromas.
Defendant raises three arguments on appeal: (1) the police stop was not based on reasonable and articulable suspicion; (2) pre-arrest statements were erroneously admitted in violation of the corpus delicti rule; and (3) the evidence was insufficient to support the ultimate verdict.
REASONABLE SUSPICION
A. Standard of Review
As was recently pointed out in
State v. White,
As in White, “[t]he result in this case ... is the same under either standard of review,” id., making any further discussion of which standard we should employ quite unnecessary to our decision. We follow the White panel’s lead in refraining from an examination, in dicta, of which standard of review “really” applies.
B. Analysis
A non-consensual investigative stop is constitutional when it meets the two-prong analysis enunciated in
Terry v. Ohio,
Defendant argues that, prior to the stop, Officer Weinmuller observed no activity inconsistent with innocent behavior and that this court has been reluctant to find reasonable suspicion under such circumstances. Defendant contends his conduct
*440
was just as consistent with that of an individual smoking a hand-rollеd tobacco cigarette. To support this argument he cites several Utah cases for the proposition that nervous behavior, when one is confronted by a police officer, does not give rise to a reasonable suspicion of criminal activity.
E.g., State v. Sery,
We cannot agree with defendant’s argument. While we have recognized that nervous behavior does not give rise tо reasonable suspicion, it does not follow, nor have we held, that the mere fact that there might be an innocent explanation for conduct wholly vitiates reasonable suspicion. To the contrary, where a defendant’s conduct is “conceivably consistent with innocent ... activity,” but is also “strongly indicative” of criminal activity, we will not hesitate to conclude that reasonable suspicion exists.
State v. Menke,
The parties do not dispute the basic facts as established in Officer Weinmuller’s testimony. 3 The trial court had no eviden-tiary disputes to resolve and its “findings” are simply an amplification of Officer We-inmuller’s testimony. In our view, the facts related by Officer Weinmuller meet the reasonable suspicion test.
The key circumstances were as follows: 1) defendant smoked a small (onе-half inch) rolled cigarette which the officer recognized as a “joint”; 2) the cigarette “disintegrated rapidly” as it burned, consistent with what the officer’s training and experience indicated was typical of a marijuana cigarette; 3) the officer, in light of her training and experience, characterized defendant’s method of inhalation as taking “hits”; 4) these events took placе in a vacant parking lot onto which defendant had driven his vehicle from a public street; 5) the vehicle’s windows were rolled up on a warm day; and 6) the officer had a close, unobstructed view of defendant’s actions.
The trial court is required to consider the “totality of the circumstances confronting the officer at the time of the seizure.”
State v. Sierra,
Given Officer Weinmuller’s uncontro-verted testimony, we conclude that although defendant’s activity was conceivably consistent with innocent activity, it was strongly indicative of criminal activity and the officer had reasonable suspicion to stop the vehicle and investigаte further. 4
*441 ADMISSIBILITY OF ADMISSIONS UNDER CORPUS DELICTI RULE
“[BJefore a defendant’s inculpatory statements can be introduced as evidence against defendant, the [prosecution] must prove the occurrence of a crime, i.e., a corpus delicti.”
State v. Johnson,
Defendant argues that because the City did not offer or produce direct evidence on the identity of the substance he was alleged to havе possessed, the City failed to meet its burden under the corpus delicti rule. Defendant asserts that, without his statements, the prosecution was unable to establish, by clear and convincing evidence, that he possessed an identifiable amount of marijuana. Thus, his admissions 6 should not have been received into evidence.
The Utah statute under which defendant was charged makes it unlawful “for any person knowingly and intentionally to possess or use a cоntrolled substance.” Utah Code Ann. § 58-37-8(2)(a)(i) (Supp.1993). Marijuana is a controlled substance, id. § 58 — 3*7—4(2)(a)(iii), and inhalation of a controlled substance constitutes use or possession. Id. § 58-37-2(27). Therefore, to establish the corpus delicti for unlawful use of marijuana, where inhalation is the gravamen of the charge, the City must show that (1) marijuana was inhaled and (2) the inhalation was accomplished knowingly and intentionally.
Defendant argues that his statements were admitted “with absolutely no direct evidence” on the identity of the substance he was alleged to possess. We disagree. While no marijuana was introduced, the sum total of the evidence was sufficient. The officer observed defendant’s windows were rolled up and he was taking “hits” from a small rolled cigarette. The cigarette was burning rapidly and in conformity with what experience told the officer was a marijuana joint. The officer then stopped the vehicle and while defen *442 dant opened the door he exhaled smoke from his mouth. Coinciding immediately with seeing the exhaled smoke, the officer smelled the odor of marijuana emanate from defendant’s mouth. As the defendant got out of his truck, the officer noticed his eyes wеre very bloodshot.
With these facts, the City was able to demonstrate, by clear and convincing evidence, that a wrong was done and that such wrong was the result of criminal conduct. Thus, in light of the fact that there was both visual and olfactory identification by an experienced officer, the corpus delicti for the crime of possession of a controlled substance was establishеd and it was not error to admit testimony concerning defendant’s inculpatory admissions.
SUFFICIENCY OF THE EVIDENCE
In reviewing a challenge to the sufficiency of the evidence in a bench trial, we review the evidence to see whether the verdict is “clearly erroneous.”
State v. Walker,
Defendant argues that the City failed to produce direct evidence of the substance allegedly possessed or a chemical analysis thereof, and thus should be required to meet the six factor test in
United States v. Dolan,
Because courts treat sufficiency of the evidence questions in drug cases where neither the substance nor expert chemical analysis is provided undеr the rubric of circumstantial evidence, we shall follow suit without endorsing the conceptual integrity of the analysis.
7
See, e.g., United States v. Baggett,
Dolan
held that lay testimony and circumstantial evidence may be sufficient, without introduction of expert chemical analysis, to establish the identity of a substance involved in a narcotics transaction.
These factors were apparently not intended as an exhaustive list, but rather as examples of the kind of evidence which could be used to prove, beyond a reasonable doubt, the existence of a controlled substance in the absence of physical evidence. The Dolan court did not require proof of all six factors for each of the counts against Dolan, nor would we require proof of every factor against defendant. However, the City provided evidence which clearly falls within the third Dolan factor, and the City provided additional proof which would arguably fall under slight variants of factors one, two, five, and six. Certainly there was еvidence that the substance was used in the same manner as an illicit drug. In addition, the officer testified as to the appearance of the substance, at least in terms of seeing a “joint,” and to smelling the substance’s distinctive aroma. She also testified that the defendant’s *443 physical appearance and behavior, i.e., bloodshot eyes and slow speech, were in conformity with those of one under the influence of marijuana. The officer’s testimony suggests that the incident was carried out with some degree of secrecy. Finally, when the officer referred to the substance by name, the defendant responded without denying her characterization, but instead acknowledged he had taken a few “hits.” Thus, we agree with the City that the evidence was sufficient even under thе Dolan analysis to support the conviction.
We note, however, that this case approaches the outer limit of what we would affirm for a possession case where the substance itself or chemical test data was not produced. We emphasize that this case involved not only the substance’s smell, but also simultaneous observation of the smoke exiting defendant’s mouth and prior observation of the act of taking “hits” frоm a “joint.” Also, defendant made several in-culpatory statements and Officer Weinmul-ler was able to observe the defendant’s physical characteristics, aspects of which were consistent with those of a person affected by marijuana.
Having fully considered the evidence and resulting inferences, we are not persuaded that the verdict is clearly erroneous.
CONCLUSION
There was a valid basis to stop defendant’s car and investigate the suspicion of marijuana use. Introduction of defendant’s inculpatory admissions did not offend the corpus delicti rule. The evidence introduced at trial is sufficient to sustain defendant’s conviction. Accordingly, the judgment appealed from is affirmed.
BILLINGS, J., concurs.
BENCH, J., concurs in result.
Notes
. This experience consisted of POST academy training and exposure to mаrijuana use during high school.
. The Terry doctrine has been codified in Utah. The applicable statute, Utah Code Ann. § 77-7-15 (1990), states:
A peace officer may stop any person in a public place when he has a reasonable suspicion to believe he has committed or is in the act of committing or is attempting to commit a public offense and may demand his name, address and an explanation of his actions.
. Defendant testified briefly, but only on the narrow issue of whether he was seized when his vehicle was stopped. That issue is not before us in view of the City's concession that the stop was a seizure under the Fourth and Fourteenth Amendments to the United States Constitution.
. Defendant argues that
State v. Chambers,
A case much closer to the instant one factually is
People v. Clark, 185
Ill.App.3d 231,
. Traditionally, the rule concerned only after-the-fact confessions, but is now applicable to admissions generally.
Johnson,
. Officer Weinmuller testified: "Well, yeah, I was talking with him, I was asking where the cigarette was, where the marijuana cigarette was.” She explained that defendant “said he gave it to his friend.” Weinmuller further testified, "I asked him how many hits he had off it, he said a few. I told him that it was.illegal to possess marijuana and to operate a vehicle while impaired by marijuana, and he said [‘] you think I would be driving if it was going to effect my driving[?']"
. We note that the question of whether evidence is direct or circumstantial is the subject of some confusion in the reported cases, in a manner which must be unsettling to evidence professors. In
Dolan,
for example, the court stated that "circumstantial proof’ includes evidence “that the substance produced the expected effects when sampled.”
