v.
McCARVER
Docket No. 59185.
Supreme Court of Michigan.
Decided August 31, 1978.
Frank J. Kelley, Attorney General, Robert A. Derengoski, Solicitor General, John A. Smietanka, Prosecuting Attorney, and Sally M. Zack, Assistant Prosecuting Attorney, for the people.
*378 Jack M. Struwin for defendant.
PER CURIAM:
The defendant was convicted by a jury of the charge of possession of a controlled substance, namely amphetamines, contrary to MCLA 335.341(4)(b); MSA 18.1070(41)(4)(b). He was sentenced to a term of 16 to 24 months in prison. The Court of Appeals reversed the defendant's conviction and remanded for a new trial because the majority of that Court was convinced that evidence of other criminal activity which had been admitted at defendant's trial deprived him of a fair trial. 72 Mich App 311; 249 NW2d 403 (1976).
On November 26, 1974, Federal and Berrien County authorities, acting pursuant to a search warrant, seized, inter alia, a quantity of pills and some marijuana from the defendant's residence. The instant prosecution for possession of amphetamines resulted. At trial defendant admitted possessing the pills in question, but he maintained that at the time he possessed them he believed they were diet pills. Guilty knowledge is unquestionably an element of the offense charged.[1]
In an attempt to prove that the defendant was not mistaken as to the nature of these pills, the prosecutor offered evidence at trial that marijuana, another controlled substance, was also *379 seized during the search of defendant's residence. The evidence was offered pursuant to MCLA 768.27; MSA 28.1050,[2] based upon the prosecutor's contention that defendant's contemporaneous possession of marijuana was a "like act". Defense counsel initially objected to the introduction of this evidence, then withdrew the objection after the trial court gave the jury an instruction on the limited purpose for which the evidence was introduced.
The majority of the Court of Appeals, while acknowledging that scienter is an element of the crime, was unconvinced that proof of contemporaneous possession of marijuana was a "like act" so as to justify demonstration at trial. The majority reasoned:
"Defendant was charged with the felony of possession of amphetamines. The proffered evidence indicated that defendant may have been guilty of the misdemeanor of possession of marijuana. A long discourse at this point on the difference in the degree of evil society associates with the possession of marijuana as opposed to the possession of amphetamines is not necessary. The law treats the two crimes in significantly different ways. MCLA 335.341(4)(b); MSA 18.1070(41)(4)(b), MCLA 335.341(4)(d); MSA 18.1070(41)(4)(d). Obviously, both offenses consist of possession of a controlled substance, but they are not sufficiently alike to permit evidence of one to be admissible under the statute in a prosecution for the other. Significantly accentuating the error in *380 this case is the fact that the trial judge twice erroneously instructed the jury that possession of marijuana was an offense punishable to the same extent as possession of amphetamines." 72 Mich App 318-319.
In dissent, Judge HOLBROOK observed:
"Defendant was in possession of two illegal drugs at the same time and place. Defendant denied knowledge of the illegal nature of the amphetamines, possession of which is a felony. Defendant was not charged with the misdemeanor offense, possession of marijuana. Nevertheless, where defendant possessed both drugs at the same time and denies knowledge of the illegal character of the drugs, possession of the marijuana is highly relevant to prove defendant's knowledge of the amphetamines' illegality." 72 Mich App 324.
In People v Duncan, 402 Mich 1; 260 NW2d 58 (1977), in construing MCLA 768.27; MSA 28.1050, we noted:
"The statute requires `like acts', not identical acts." 402 Mich 12.
We believe that evidence concerning the simultaneous possession of marijuana by the defendant was admissible pursuant to this statute. That evidence tends to show the absence of mistake on the part of defendant with regard to his possession of amphetamines. Both marijuana and amphetamines are presently controlled substances, possession of which is illegal. Proof that the defendant possessed, at the same time, a controlled substance other than the one for possession of which he is being prosecuted is a sufficiently similar act to warrant admission pursuant to the statute to show absence of mistake.
Furthermore, we note that the trial court gave a *381 cautionary instruction to the jury in this case which informed them of the limited purpose for which evidence concerning the defendant's contemporaneous possession of marijuana was introduced. The jury was thus adequately advised in this regard and indeed, defense counsel, who had initially objected to such evidence, was so satisfied by the limiting instruction that he indicated on the record that he was withdrawing his objection to this evidence.
In People v Duncan, supra, we said:
"It is well settled that the determination of whether the probative value of similar acts testimony is substantially outweighed by its unfairly prejudicial effect is within the sound discretion of the trial judge. See People v DerMartzex, 390 Mich 410; 213 NW2d 97 (1973), and authority cited therein." 402 Mich 14.
The Court of Appeals majority felt that even if the evidence concerning possession of marijuana was considered to be a "like act" its probative value was clearly outweighed by the prejudice to the defendant. We disagree. To the extent that the introduction of evidence of this type tends to further prove the prosecutor's case, it will always be of some prejudice to the defendant. However, we are unconvinced that in this particular case the introduction of the "like act" evidence was of such an inflammatory nature as to cause the members of the jury to render a finding of guilt which they might otherwise not have been disposed to do. Whatever "prejudice" might have emanated from the introduction of this evidence was certainly tempered by the cautionary instruction given by the trial court to the jury. Indeed, as noted supra, this cautionary instruction prompted defense counsel to withdraw his previously proffered objection *382 to this evidence. Accordingly, we believe that the Court of Appeals conclusion that this evidence should have been excluded to be error.
In reversing, the Court of Appeals also concluded that the defendant had been prejudiced at trial because a Federal agent who was testifying for the prosecution indicated that the defendant was a convicted felon. The majority was also troubled by an answer given on cross-examination by a state police detective as to whether he had tried to get someone to entrap the defendant. The witness answered:
"I recall talking to several different persons, and they advised me that, yes, they were aware of people who were in criminal activities; they were interested in assisting me and the name Al McCarver was brought into the picture."
The prosecutor pursued this point during redirect examination of this witness:
"Q. You said the name Al McCarver came up in various conversations that you had with various people in the year you have been here; is that correct?
"A. That's correct.
"Q. Did you bring up his name?
"A. No, ma'am.
"Q. Was his name brought up to you?
"A. Yes it was.
"Q. Was it brought up in connection with alleged criminal activity?"
Finally, at this point defense counsel interposed an objection claiming that this line of inquiry was irrelevant and that it involved hearsay. The trial judge indicated that in his opinion these matters *383 were irrelevant to the case at bar and sustained the objection.
The Court of Appeals concluded that the testimony of the Federal agent and the testimony of the state police detective when combined with the evidence concerning defendant's simultaneous possession of marijuana united to deprive the defendant of a fair trial. Since we have concluded that the evidence concerning defendant's possession of marijuana was properly admitted by the trial judge, we remand the case to the Court of Appeals for consideration of the question of whether the testimony of the Federal agent and the state police detective, standing alone, or when combined with other issues raised by the defendant in the Court of Appeals but not discussed by that Court, served to deny the defendant a fair trial.
Accordingly, pursuant to GCR 1963, 853.2(4), in lieu of granting leave to appeal, we reverse the judgment of the Court of Appeals and remand the case to that Court for further proceedings consistent with this opinion.
WILLIAMS, COLEMAN, FITZGERALD, RYAN, and BLAIR MOODY, JR., JJ., concurred.
LEVIN, J. (dissenting).
Leave to appeal should be denied.
The issue is whether the Court of Appeals erred in reversing McCarver's conviction for possession of amphetamines on the ground that marijuana seized with the amphetamines should not have been admitted in evidence.
The marijuana was offered to show that McCarver knew that the pills were amphetamines. The Court of Appeals said that possession of marijuana and possession of amphetamines "are not sufficiently alike to permit evidence of one to be admissible *384 under the statute in a prosecution for the other".[1] This Court, in reversing the Court of Appeals, states that the marijuana
"tends to show the absence of mistake on the part of defendant with regard to his possession of amphetamines. Both marijuana and amphetamines are presently controlled substances, possession of which is illegal. Proof that the defendant possessed, at the same time, a controlled substance other than the one for possession of which he is being prosecuted is a sufficiently similar act to warrant admission pursuant to the statute to show absence of mistake."
I
Assuming, arguendo, that possession of the two substances are "like" acts,[2] it does not follow that possession of one tends to indicate knowledgeable possession of the other.
The statute makes it "unlawful for any person knowingly or intentionally to possess a controlled substance" unless it was obtained pursuant to a valid prescription or order of a practitioner or is otherwise authorized by the act.[3] It therefore appears that it would be a defense that McCarver did not know that the pills were amphetamines. Since he claimed that he had been led to believe that the pills were caffeine diet pills, similar acts evidence that was probative of his knowledge that they were amphetamines might be admissible under the statute.
The probative value of the marijuana on the issue on which it was offered (whether these pills were amphetamines), depends on whether users or *385 possessors of marijuana know, in significantly greater numbers than the general population, that pills of the kind seized are amphetamines and not caffeine. No empirical evidence was offered, and it does not appear that either the trial judge or the members of this Court can decide the probativeness of marijuana on the amphetamine issue based on personal experience. There is, therefore, no rational basis on or apart from the record for drawing the inference that a user or possessor of marijuana on that account would know that the pills in question were amphetamines and not caffeine.
The marijuana was not admissible on the premise that one who would violate the law prohibiting possession of one controlled substance is more likely to violate that law as to another substance. That is the prohibited purpose and inference; similar acts evidence is not admissible to prove a character trait or propensity to commit offenses generally or of a particular kind and the trier of fact is precluded from drawing the inference that because a person has committed one crime he might have or has committed another.[4]
A number of courts have held in similar cases that evidence of possession of marijuana is not admissible. One noted that the effect of the admission of such evidence "would be to generate heat instead of diffusing light" and that such evidence had a "minute peg of relevancy" which is "entirely obscured by the dirty linen hung upon it". State v Portrey, 6 Wash App 380, 384; 492 P2d 1050, 1052 *386 (1972) (possession of marijuana held improperly admitted in prosecution for possession of LSD); Sweatt v State, 251 Ark 650, 652; 473 SW2d 913, 914 (1971) (evidence of past sales of marijuana held improperly admitted in prosecution for sale of LSD); and State v Spraggin, 77 Wis 2d 89; 252 NW2d 94 (1977) (in prosecution for delivery of heroin, possession of marijuana held improperly admitted).
II
The Court has no basis for concluding that the error in admitting the marijuana was harmless beyond a reasonable doubt. We do not know the views of those comprising the jury on possession and use of marijuana. If the jury represented a cross-section of the community, it was comprised of persons who use or have used and persons who have a deep aversion to users of marijuana. Persons who have such an aversion might well have resolved a reasonable doubt about McCarver's guilt against him. The danger of unfair prejudice becomes particularly evident when this evidence is considered with the testimony[5] characterizing McCarver as a convicted felon and associating him with criminal activity in general.
III
The Court of Appeals did not regard the action of McCarver's lawyer in withdrawing his objection to the admission of the marijuana as significant. He may have done so because the argument over his objection took place in the presence of the jury and, after the cautionary instruction was given, *387 the judge asked him, again in the jury's presence, whether he wished to maintain his objection. Counsel might have concluded that it would only have compounded the prejudice to have insisted on the objection.
Moreover, the purpose of requiring an objection is to provide the judge with an opportunity to rule on the objection and avoid the error and an unnecessary new trial. That purpose was served when the lawyer made his objection.
The error was preserved by objection. The judge had an opportunity to avoid error; he did not. The objection was overruled and a "cautionary" instruction was given. There is a record which we can review. Withdrawal of the objection was wholly gratuitous.
IV
The cautionary instruction, mandatory whenever similar acts evidence is admitted, was not adequate. It was given, as required, when the evidence was admitted; it was not repeated in the charge to the jury. The judge said: "the fact that he had marijuana would not  if he had that, would not make him guilty of the charge here", but he also said "in examining the credibility and plausibility of a claim, perhaps, that he didn't know that he had the amphetamines and the like, you may have this in evidence for such weight as you feel it is worth, for such assistance". (Emphasis supplied.)
The instruction was subject to the construction that the jury was to consider the other offense evidence on the issue of credibility. Moreover, the judge failed to instruct the jury specifically that although McCarver may have committed another *388 offense it should not draw the prohibited inference that he committed this offense, nor did he instruct it not to convict McCarver because he may appear to be a person of bad character or guilty of other improper conduct.
V
A cautionary instruction on the limited use of other offense evidence, in contrast with most cautionary instructions, is not given because such evidence was inadvertently brought to the jury's attention, but, rather, because it is deliberately admitted.
Such a cautionary instruction cannot cure an error in the admission of other offense evidence. The caution is that the jury is not to draw the prohibited inference or convict the defendant because of bad character or other improper conduct. The instruction, however, is also that the jury is to consider the evidence for the purpose for which it was admitted  here, to show knowledge that the pills were amphetamines. The caution does not relate to the use of the evidence on the issue of knowledge, but against mis-use as evidence of a propensity to commit offenses. The instruction which told the jury that it could consider the other offense evidence on the issue of whether McCarver knew he possessed amphetamines did not cure but only compounded the error of admitting such evidence for that purpose.
We would deny leave to appeal.

"(4) It is unlawful for any person knowingly or intentionally to possess a controlled substance unless the substance was obtained directly from, or pursuant to, a valid prescription or order of a practitioner while acting in the course of his professional practice, or except as otherwise authorized by this act. Any person who violates this subsection with respect to:

It was the prosecution's theory that the defendant was a trafficker in drugs. While possession of a large quantity of marijuana might be some evidence that the defendant was a "trafficker", possession of a small quantity of marijuana does not permit that inference. The ubiquitous use of marijuana by persons who do not traffic in drugs precludes such an inference.
