QUICK TAKEAWAY
The Controlled Drugs and Substances Act (CDSA) is a federal law in Canada that regulates the possession, production, distribution, and sale of controlled substances to protect public health and safety. It classifies substances based on their potential for harm and abuse. It sets out rules for obtaining and using them for legitimate purposes while imposing penalties for their production and distribution. The CDSA has multiple schedules and has been amended several times since its enactment in 1996 to adapt to new and emerging drug threats.
