Barbiturates, benzodiazepines, and anabolic steroids fall under which schedule of the CDSA?

The correct answer is Schedule 4 of the Controlled Drugs and Substances Act (CDSA) in Canada. This schedule encompasses substances that are considered to have a therapeutic value but also have a potential for abuse and dependence. Barbiturates and benzodiazepines both have sedative properties and are used in the treatment of various conditions, including anxiety and insomnia; however, they are also associated with a risk of addiction when misused. Anabolic steroids, which are often used for muscle building and athletic performance enhancement, also fall under this category due to their potential for abuse and associated health risks.

Schedule 4 substances are subject to more stringent regulations compared to those in lower schedule categories, reflecting their necessity for medical supervision while recognizing their potential for misuse. This regulation helps ensure that they are prescribed and dispensed safely within a clinical context.
