Ephedrine and pseudoephedrine are categorized as precursors in which schedule of the CDSA?

Ephedrine and pseudoephedrine are categorized as precursors in Schedule 6 of the Controlled Drugs and Substances Act (CDSA). This classification reflects their potential to be used in the illicit manufacture of controlled substances, particularly methamphetamine. It requires special controls for sale and provides a framework for regulation to help mitigate the risks associated with their misuse.

Schedule 6 specifically addresses substances that are not as controlled as those listed in higher schedules but are still recognized for their ability to contribute to illegal drug production. The categorization supports monitoring and regulation to prevent diversion into illegal markets, which is necessary considering the prevalence of such substances in drug-related crimes.

Other schedules either pertain to substances that are theoretically less controlled or those that contain highly controlled drugs requiring more stringent regulations. By understanding this classification, pharmacists and pharmacy staff can maintain compliance with the law and ensure the safe handling of these substances in practice.
