Controlled Drugs and Substances Act

This site describes the schedules of the Canadian Controlled Drugs and Substances 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).

Controlled Drugs and Substances Act

Includes the sweeping and roundly condemned omnibus crime bill, Bill C-10 the Safe Streets and Communities Act.

The Harper Government, proudly and wilfully dismissive of evidence and experience, forced this bill through the House of Commons on 12 Dec 2011 by limiting debate in both the House and Committee hearings. It is currently speeding through the Senate.

This loathsome legislation denigrates Canada and demeans us all. Please speak out against C-10 while there is still a chance to stop it from destroying countless lives and families, at an estimated cost of $19,000,000,000. That’s nineteen billion dollars.

Tell the Senate you oppose C-10 by adding your name to “Don’t rubber stamp the Crime Bill” a petition from leadnow.ca. It will only take a minute. Together, we may yet stop this lunacy.


Includes the 19 Feb 2011 proposal to add Salvia divinorum and Salvinorin A to Schedule III. Read more about Health Canada’s agenda for S. divinorum (updated 19 Oct 2011.)

New: The regulatory status of almost 2800 substances (at least as far as Health Canada is concerned).
