This site describes the schedules of the Canadian Controlled Drugs and Substance Act (CDSA).

The CDSA is the federal legislation that spells out which chemicals and plants Canadian citizens may not grow, buy, sell, swallow, hold, or otherwise lust after.

If you do grow, buy, sell, swallow, hold, or otherwise lust after any of these chemicals or plants you may be arrested, fined, jailed, or all three.

Also described here are the United Kingdom Misuse of Drugs Act (MDA), the United Nations Drugs and Substances under International Control, and the United States Controlled Substances Act (CSA).
