Final answer:
a. Controlled Drugs and Substance Act
The legislation related to narcotics in Canada is the Controlled Drugs and Substances Act, while in the United States, the Controlled Substances Act and the Federal Food, Drug, and Cosmetic Act oversee drug regulation.
Step-by-step explanation:
The feudal legislation that relates to narcotics in Canada is the Controlled Drugs and Substances Act (CDSA). This act is the legislative framework through which the possession, trafficking, production, and distribution of specific drugs and substances, including marijuana, are regulated. The CDSA was created to help control substances that can alter mental processes and that may produce harm to health and to society when diverted or misused.
In contrast, the United States has the Controlled Substances Act (CSA), which declares marijuana and other drugs as controlled substances and makes their sale and use prosecutable. Also, the Federal Food, Drug, and Cosmetic Act (FD&C Act) is a significant piece of legislation enforced by the FDA which covers a variety of areas concerning the safety and efficacy of drugs, biological products, and medical devices in the United States.
