¶2I concur generally in the decision of the court that the judgment should be affirmed. I disagree with that part of the opinion which holds that knowledge on the part of the defendant, that the substance he sold was not the substance he represented it to be, is not an element of the offense. The better rule is that a prescribed culpability requirement should apply to all material elements of the offense. See Model Penal Code, § 2.02(4).
