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).

A, B… Z	Consolidated Index of Drugs and Substances I'm starting to add supplimentary names not actually listed in the legislation: common initialisms (DOC), trade names (Valium®), street names (Foxy) etc. This is an ongoing but low-priority project. I welcome your suggestions for novel names (credited if you like.)

	Would you like to know what substances are proscribed in China? I would! Does such a list exist? If so, where is it? Can you help me find it, fellow researcher? If you can—ideally in English since I neither read nor speak any analogue of Chinese—you will get full credit for the discovery, and my sincere thanks. Please contact me and maybe together we can improve this site by documenting the safeguards conferred on more than 1.3 billion law-abiding citizens!
