Pennsylvania v. Herman (majority)Annotate this Case
Appellee was charged with a single count of possession with intent to distribute, or possession, of a “designer drug,” a substance similar to a scheduled controlled substance, not the same. The trial court here determined experts have been unable to reach an agreement on a method for analyzing and determining the similarities between the chemical structures the controlled substance and its designer analogue, leading it to conclude this disagreement rendered the Pennsylvania designer drug statute unconstitutionally vague. The Pennsylvania Supreme Court reversed, finding the common pleas court did not account for the difference between the concepts of analogue and substantial similarity, the latter of which is more readily apprehensible to the lay citizen in the context of comparing chemical structures; nor did it recognize that, unlike the controlled-substance provision, the designer drug provision included a narrowing scienter specification. Moreover, the Court found in this case that there were “considerable similarities” as between the two molecules based on their two-dimensional diagrams.
