Drug offences in Canada are prosecuted under the Food and Drug Act and the Controlled Drugs and Substances Act sections 4 through 7.
Controlled substances in Canada are organized by schedule. Schedule I substances include opiates (like heroin), cocaine, methamphetamine, other amphetamines (such as MDMA) and several other less-popular drugs. Schedule II substances include large amounts of marijuana and its derivatives. Schedule III covers many psychedelic drugs as well as some pharmaceuticals. Schedule IV drugs include some pharmaceuticals that are legal to possess, but illegal to seek, traffic or export. Further schedules include personal quantities of cannabis and substances that can be used to produce drugs.
