Provides that a fentanyl analogue shall be deemed to be a schedule I opiate

This bill (S 3934) defines "fentanyl analogue" as any synthetic opioid structurally similar to fentanyl through specific chemical modifications (e.g., changes to its ring structures or groups). It classifies all such analogues as Schedule I drugs under New York's public health law, treating them like the most strictly controlled narcotics. The law also removes the requirement for individuals to know a substance's chemical structure to be charged with possession or sale of these analogues. Exceptions include FDA-approved medications and substances used under investigational exemptions.
