delivered the opinion of the court:
Defendant was found guilty in a jury trial of distribution of lookalike substances (111. Rev. Stat. 1983, ch. 56V2, par. 1401(b)) and was sentenced to 30-months’ probation and fined $5,000 plus costs. Defendant appeals his conviction.
At trial, John Carey, an investigator for the Illinois Attorney General’s office, testified that on October 27, 1982, he went with a partner to defendant’s company, Midwestern Wholesale Supply Company (MWS) located at 311 North Des Plaines Avenue, Chicago. Carey met with defendant and Brian Bolggess at MWS.
Carey asked defendant if he had any of the big black capsules he had advertised in Hustler magazine. That advertisement referred to the capsules as “body stimulants.” Defendant replied he sold the capsules for $50 per thousand. Carey told defendant he would take a thousand of the big black capsules.
Defendant went into a back room. When he returned, he filled out a receipt and gave Carey a bottle of black capsules. The label on the bottle indicated it was manufactured for MWS, 311 North Des Plaines, Office 101, Chicago. It was marked “Decongestant Capsules,” stated the ingredients of the capsules, and contained some warnings. Mr. Carey paid defendant $53.50 for the bottle. Defendant said he appreciated the business and hoped he would see Carey again soon.
Later that same day, Carey and several law enforcement officials returned to MWS and executed a search warrant and two аrrest warrants. These individuals took photographs of defendant’s business premises, including shelves holding bottles of substances, and confiscated other substances and documents. Of this evidence, several of the photographs, two books, a lease, and two boxes containing pills were introduced by the State at trial.
Dr. Jorge Pirl, Assistant Chief Toxicologist for the Illinois Department of Public Health, testified at trial that he had performed an analysis of the capsules purсhased by Carey. This analysis revealed that the capsules contained caffeine and phenylpropanolamine. Caffeine stimulates the central nervous system, and phenylpropanolamine acts as both a decongestant and a stimulant. He had performed an analysis of the contents of one of the capsules seized by Carey, and they also contained caffeine and phenylpropanolamine.
Dr. Pirl identified an amphetaminе capsule and testified that it was a controlled substance. On cross-examination, he testified that not all amphetamines are black, that the capsule purchased by Carey and the amphetamine had different markings, and that the capsule purchased by Carey was larger.
Barry Kelter, an investigator for the Illinois Attorney General’s office, testified that he went to MWS with Carey on October 27, 1982, and waited outside when Carey entered MWS at about 10:30 a.m. Around 4:30 p.m. he went back to MWS with other individuals and served a search warrant. He identified various pictures taken on the premises.
Laureen Morrison, a law clerk in the Attorney General’s office, testified that she examined eight boxes of documents seized at MWS.
The defendant did not testify or present any evidence.
On appeal, defendant urges that the trial court, erred in denying his motion to dismiss the indictment. Defendant styles his first contention under this argument as challenging the definition of look-alike substances in the Illinois Controlled Substances Act (Ill. Rev. Stat. 1983, ch. 56^2, par. 1102(z)), on the grounds that it is unconstitutionally-vague in violation of the fourteenth amendment and article I, section 2, of the Illinois Constitution. However, defendant also challenges as unconstitutionally vague section 404 of the Act (Ill. Rev. Stat. 1983, ch. 56½, par. 1404). Among other things, this section prohibits the knowing distribution of a look-alike substance.
We find that defendant’s challenge fails because he was charged for conduct “clearly prohibited” by the statute. (People v. Greene (1983),
The defendant denies that his conduct was clearly prohibited, and contends that his challenge has merit because he merely sold Carey a bottle of capsules identified as decongestants containing caffeine and phenylpropanolamine. Defendant refers us to the case of People v. Matkovick, citing it for the proposition that “vagueness challenges to statutes which do not involve First Amendment freedoms must be examined in the light of the facts of the case аt hand.” People v. Matkovick (1984),
The defendant in Matkovick was charged with the unlawful distribution of a look-alike substance under section 404(b) of the Illinois Controlled Substances Act after allegedly selling to an investigator a substance he represented as amphetamines. The trial court allowed defendant’s motion to dismiss the charge on the grounds that section 404(b) of the Act was unconstitutional. On appeal, our supreme court followed the analysis applied in Village of Hoffman Estates v. Flipside, Hoffman Estates, Inc. (1982),
Applying this analysis to the instant case, the distribution of look-alike drugs is not constitutionally protected conduct. Neither are sections 404(b) or 102(z) of the Act impermissibly vague in all of their applications. A statute may be found unconstitutionally vague when its terms are so indefinite that “persons of common intelligence must guess at its meaning.” (Fagiano v. Police Board (1983),
Defendant argues the statute is vague since the jury convicted him merely by finding the capsule defendant sold to Carey was similar in color and shape to an exhibit of an amphetamine capsule. This contention is without merit because the legislature clearly intended to prohibit distribution both of substancеs which actually match controlled substances and of substances leading “a reasonable person to believe that the substance is a controlled substance.” 111. Rev. Stat. 1983, ch. SG1^, par. 1102(z).
Further, the statute’s scienter requirement limits the reach of section 404(b) to those who intend to pass off a noncontrolled substance as a controlled substance. To succeed in this deceit, such individuals necessarily must determine whether the noncontrolled substance. looks like the controlled one. Therefore, the statute is not vague to those such as defendant who knowingly distribute look-alike substances.
Defendant chronicles possible combinations of colors and shapes of various controlled substances and contends that physical resemblance to a controlled substance should not be the basis for a conviction. We note that defendant’s suggested cure for the alleged vagueness he challenges wоuld require the statute to delineate the physical appearance of every controlled substance which a noncon-trolled substance should not resemble. We reject this laundry-list approach since it ignores a basic tenet of the vagueness doctrine that due process principles do not require “impossible standards of clarity.” Kolender v. Lawson (1983),
Defendant claims the trial court erred in denying his motion to dismiss the indictment also because the penalties provided in section 404(b) of the Act are unconstitutionally disproportionate. Under section 404(b), a person who distributes a look-alike substance is guilty of a Class 3 felony and can be fined up to $150,000. Under section 401(f), a person convicted of distributing a controlled or counterfeit substance, depending on the amount, is guilty of a Class 3 felony and can be fined no more than $100,000 if the offense involves a Schedule IV substance. Section 401(g) similarly provides that аn offense involving a Schedule V controlled or counterfeit substance is a Class 3 felony and a person can be fined no more than $75,000.
Our supreme court has held that the Controlled Substances Act is a proper exercise of the State’s police power. (People v. Matkovick (1984),
The precursors of the present statute have been reviewed frequently by our supreme court. An earlier version of the Act which established a more severe penalty for possession of certain controlled substances than was established for delivery of those same substances was found to violate the due process clause of the Illinois Constitution in People v. Bradley (1980),
In 1979, the legislature amended the Act by increasing the penalty for delivery of a Schedule IV or V controlled substance to a Class 3 felony. Yet it retained the respective fines of $10,000 and $5,000 for delivery of Schedule IV or V substances, while a person convicted of delivery of a purported controlled substance could have been fined up to $15,000. In People v. Manuel (1983),
Before Manuel was decided, the legislature had indeed amended section 404 of the Illinois Controlled Substances Act to include the look-alike substances definition and sentencing provisions. (Pub. Act 82 — 968, eff. Sept. 7, 1982.) This is the Act under which defendant in the instant case was convicted. Statements by the House and Senate sponsors of the proposed amendments clearly reflect that the legislature recognized special dangers connected with look-alike substances. (House Debates, H.B. 2079, May 18, 1982, at 123-24; House Debates, H.B. 2079, May 20, 1982 at 156-63; Senate Debates, H.B. 2079, June 24, 1982, at 51-52.) Co-sponsors of the bill provided a preamble to the Act expressing the legislature’s intent to create a penalty provision distinct from that applicable to controlled substances, based upon the different type of harm stemming from distribution of look-alike drugs. This preamble was designed to address the concerns of the supreme court in Wagner, and it states that the harm from look-alike substance offenses “is in fact greater than that of many actual controlled substances.” (1982 Ill. Laws 2368, Preamble to Pub. Act 82 — 968.) When the words of a statute are plain and the legislative purpose manifest, the purpose must be given effect. (Totten v. State Board of Elections (1980),
Defendant next contends that the evidence was insufficient to sustain a guilty verdict. He asserts that the State failed to prove that: (1) the capsules distributed were not controlled substances; (2) defendant knowingly distributed a look-alike substance, and (3) a reasonable person would be led to believe that the substance distributed by the defendant was a controlled substance. Because we conclude on other grounds that the judgment must be reversed and the cause remanded for a new trial, it is inappropriate for us to analyze the evidence in greater detail than necessary to resolve the issues we deem disposi-tive. See People v. Gordon (1984),
The appellate court, however, has a duty to address a defendant’s sufficiency of evidence question to avoid placing defendant in double jeopardy upon a retrial. (People v. Taylor (1979),
In its instructions to the jury, the trial court stated:
“You are further instructed that evidence has been received that the dеfendant has been involved in an offense other than that charged in the indictment. This evidence has been received solely on the issue of the defendant’s knowledge. This evidence may be considered by you only for the limited purpose for which it has been — for which it was received.”
It is defendant’s position that the evidence referred to was two boxes of pills seized from defendant’s business. He argues that the instruction was improper because it advised the jury that possession of the substances in the boxes was a criminal offense. In effect, it instructed the jury that the substances were look-alikes, a material element of fact which the State had to prove. Defendant also argues that the instruction was erroneous because there was no evidence that he was involved in any other offense.
We agree with defendant that the instruction was fatally defective. The evidence it referred to consisted of onе box of pills similar in color and size to the capsules defendant was charged with selling, and one box of pills identical to the ones sold. The jury heard that investigators for the State had confiscated the boxes on the day of defendant’s arrest. During closing argument, the State asserted that the two boxes showed the defendant knew what he was doing. Since the instruction referred to defendant’s involvement in an offense, we think it likely the jury believed these pills were in fact look-alike substances. Because one box contained pills identical to the capsules at issue, in effect the instruction improperly assumed one of the elements of the crime charged. People v. Murawski (1946),
The State asserts that a trial court may properly give an instruction to the jury with respect to the limited use for which the other crimes evidence was admitted when the evidence of other crimes tends to establish defendant’s knowledge, and when, during trial, the court admonishes jurors to consider the evidence only for that limited purpose. (People v. Peebles (1983),
But the problem with the wording of the instruction was aptly phrased by the State itself during the instruction conference:
“[T]he language deals with it being another offense, and, in fact, it was not presented as though it is another offense ***.”
It appears that defendant’s instruction that he was not on trial for any act or conduct not alleged in the indictment was accepted by the court to resolve the problem. However, where an erroneous instruction is given, the giving of a correct instruction on behalf of defendant will not cure the error. (People v. Chronister (1942),
Moreover, we find the admission of the two boxes of pills was itself erroneous. Although the evidence came in on the issue that defendant knew he was distributing look-alike substances, the jury was not permitted to examine these pills or to hear testimony about them and could only have speculated that the pills were look-alikes. We cannot conclude that this error was harmless. The evidence had little, if any, probative value as to defendant’s knowledge. Combined with the improper other offense instruction, it had substantial prejudicial impact on the jury. (See People v. Funches (1978),
Defendant argues several additional errors were committed at trial. Although this cause must be reversed and remanded for a new trial on other grounds, we choose to discuss those questions raised by defendant which may arise again on retrial. First, he cоntends that the trial court erred in admitting two books, Basic Drug Manufacturing and Drug Manufacturing for Fun and Profit, seized in a search of defendant’s premises. Defendant argues that this literature relating to drug manufacture was irrelevant to the offense of distributing look-alike substances and extremely prejudicial. The State counters that this evidence allowed the jury to conclude that defendant perused the books and acquired knowledge of what controlled substances loоk like.
We agree with defendant that the books were irrelevant to the offense of distributing look-alike substances. While offered and admitted for the limited purpose of showing defendant’s knowledge of what controlled substances looked like, there is no evidence in the record that the books contained information regarding amphetamines. The jury was not permitted to have the books during their deliberations, so it cannot be said that they could infer defendant’s knowledge from the fact that the books were found on his business premises on the day of his arrest.
We disagree, however, that the error of admission inflamed the jury or extremely prejudiced defendant. The evidence was introduced by exhibit-identification number during direct examination of a law clerk who had reviewed the evidence seized. She identified one book only as a booklet found in a box. The books were admitted into evidence without reference to thеir titles. The State referred to the titles during closing argument, but commented on the books only momentarily, connecting them to defendant’s knowledge. Defense counsel emphasized the evidence was irrelevant to the charge of distribution and introduced only to influence the jury as to defendant’s bad character.
Under these circumstances, we believe the erroneous admission of the evidence was harmless. (See People v. Falkner (1985),
Defendant also argues the State’s expert witness should not have been permitted to testify about the effects of caffeine and phenylpropanolamine on the body. We are not persuaded. Expert testimony is admissible on matters requiring scientific knowledge. (People v. Schyman (1940),
Defendant’s assertion that the trial court erred in permitting Carey to answer the question of why he was going to defendant’s premises is likewise without merit. The complained of testimony consisted of that one question and Carey’s brief answer, “To purchase look-alike drugs.” The trial judge admonished the jury to disregard the word drugs. This court reviewed a related situation in People v. Bradley (1971),
Finally, defendant contends that the admission of an enlarged photograph of an amphetamine capsule, the capsule itself and the expert witness’ testimony relating to the capsule was reversible error. However, we agree with the State that the jury was entitled to compare the amphetamine to defendant’s capsule to determine whether a reasonable person would have thought they were look-alikes. The evidence was relevant and the trial court did not abuse its discretion in admitting the evidence and testimony. See People v. Jones (1983),
For the foregoing reasons, the judgment of conviction of the circuit court of Cook County is reversed and this cause is remanded for a new trial in accordance with the views expressed herein.
Reversed and remanded.
