Which law regulates the distribution and use of controlled substances in Canada?

The distribution and use of controlled substances in Canada is governed by the Controlled Drugs and Substances Act. This legislation specifically aims to control the possession, distribution, and usage of substances that can lead to addiction or are considered harmful to individuals and society. The act classifies controlled substances into different schedules based on their potential for abuse and therapeutic value, establishing a framework for their legal use and regulation.

In contrast, the Food and Drug Act primarily focuses on the regulation of food, drugs, and other consumer products to ensure safety and efficacy, but it does not dedicate specific provisions to controlled substances. The Drug Identification Number Act references the system for identifying drug products but does not regulate controlled substances. The Prescription Drug Monitoring Act pertains to the monitoring and oversight of prescriptions but is not the primary legislation governing the control of drugs and substances. Thus, the Controlled Drugs and Substances Act is explicitly designed for this purpose, making it the correct choice.
