delivered the opinion of the court:
Defendant-appellant, Lawrence Bitterman, was convicted following a bench trial of the offenses of speeding, improper lane usage and driving under the combined influence of alcohol and drugs. He received sentences of three months’ supervision on the former two offenses, and one-year supervision on the latter conviction. Defendant has appealed from the latter judgment and sentence.
Defendant has raised only one issue in this forum. Specifically, defendant complains that his conviction cannot stand in the absence of expert or lay testimony or opinion that he was under the influence of drugs at the time of his arrest. He relies principally on this court’s decision in People v. Jacquith (1984),
The facts adduced at trial show that on December 21, 1984, at 3 a.m., Wilmette police officer Kasppar observed defendant speeding. When the officer followed the defendant’s car, he noted that defendant twice swerved over double yellow lines. As a result, the officer pulled defendant over. When defendant exited his car, he staggered and needed to lean on his car to maintain his balance. Kasppar noticed a strong odor of alcohol on defendant’s breath, and also observed that defendant’s eyes were bloodshot and glassy. After defendant failed several field sobriety tests and admitted that he had been drinking at a party prior to the traffic stop, Kasppar placed defendant under arrest for driving under the influence of alcohol, and took defendant to the police station.
At the station, defendant submitted to a breathalyzer test, the result of which was a blood alcohol reading of .14%. Defendant stipulated to these results at trial. After being advised of his Miranda rights (Miranda v. Arizona (1966),
Defendant took the stand on his own behalf. He was unable to recall Kasppar either asking him about marijuana usage, or telling Kasppar that he had been smoking. Defendant denied at trial that he had been smoking. He did, however, admit giving Kasppar a packet of “some substance,” but claimed to be unaware of its contents.
As noted, the trial court found defendant guilty of speeding, improper lane usage and driving under the combined influence of drugs and alcohol.
Defendant’s contention is that the State failed to prove him guilty of the intoxication offense beyond a reasonable doubt, specifically challenging the evidence of drug usage. The Illinois Vehicle Code provides, in relevant part:
“Sec. 11 — 501. Driving while under the influence of alcohol, other drug, or combination thereof.
(a) A person shall not drive or be in actual physical control of any vehicle within this State while:
* * *
4. Under the combined influence of alcohol and any other drug or drugs to a degree which renders such person incapable of safely driving.” (Ill. Rev. Stat. 1983, ch. 952/2, par. 11 — 501(a)(4).)
In People v. Jacquith (1984),
In Jacquith, this court noted the paucity of authority in Illinois concerning proof of drug intoxication. As a result, we resorted to case law from Texas and California in ascertaining what kind and quantum of proof would suffice to meet the State’s burden. (People v. Jacquith (1985),
There is nothing in the Jacquith opinion, however, which would indicate that opinion testimony by the arresting officer is the sole source of proof of drug intoxication or a necessary prerequisite to a conviction. Defendant’s argument reads into that decision a burden that was neither intended nor could rationally be imposed upon the State.
As a matter of logic, it seems almost axiomatic that other forms of evidence would be adequate to meet the State’s burden of proof, and indeed would be preferable. The opinion of a qualified police officer that an individual was under the influence of a drug, or drugs is by its nature circumstantial evidence, since it depends on that officer’s drawing an inference of drug intoxication from the facts he observed personally. (See People v. Rhodes (1981),
Here, there was direct evidence concerning defendant’s drug usage: his own admission. It is well established that an admission by the accused constitutes direct evidence of guilt. (People v. Lippert (1984),
In deciding the case, the trial court accepted Kasppar’s testimony that defendant acknowledged smoking marijuana, and rejected defendant’s denial. “In a bench trial, the credibility of witnesses and the weight to be afforded their testimony is determined by the trial court, whose judgment will not be set aside unless the proof is so unsatisfactory as to create a reasonable doubt of guilt.” (People v. Son (1982),
In light of our disposition of this issue, we need not address the State’s alternative argument.
Accordingly, the judgment of the circuit court is affirmed.
Affirmed.
BILANDIC, P.J., and STAMOS, J., concur.
