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, the United States Controlled Substances Act (CSA), and substances controlled by the European Union.

  • On 10 Dec 2014 the third and final version of The Misuse of Drugs Act 1971 (Amendment) (No. 2) Order 2014 was passed, coming into force 8 Jan 2015.

    • AH-7921.
    • An infinite number of tryptamines (of which an infinite number are not known to exist).

    They’ve made a bit of a hash of this one. [With thanks to Sean D. for alerting me.]

    • Added the N-benzyl analogues of any compound derived from pretty much everything in PiHKAL (but not N-Benzyl-MDA), including any and all benzyl substituents, to Class A. An infinity of substances.
    • Added Benzofuran, Indole and Indane, along with their didehydro counterparts, with a 2-aminoethyl substituent (which they incorrectly cite as 2-ethylamino—a nonsensical name I think) at any phenyl position, including almost limitless additional substitution of the ring system and/or the 2-aminoethyl substituent, to Class B. Six more infinities.
    • Moved Ketamine to Class B from Class C.
    • Added Lisdexamphetamine to Class B.

Readings on drug law design and policy—the good, the bad, and the unworkable.

I would like to share with you the mountains of solid, empirical evidence Health Canada has amassed on new psychoactive substances. And, if any existed, I surely would share it. Sadly, as far as I can tell Health Canada stopped doing anything approaching credible science long ago. PowerPoint bullet lists of tabloid headlines is about their current level of intellectual engagement.

Fortunately not every country has abdicated public health in favour of empty self-congratulatory piffle. Italy, for example, just published 1700 pages of hard, analytical data on over 250 new drugs. There is more substantive content in this single document than the whole of Health Canada’s truly pathetic and embarrassingly irrelevant website. Hyperbole? No. Take a look at their Science and Research Page and tell me that fills you with patriotic pride.
