Is 1P-LSD legal in Canada?

Confirmed against a primary sourceVerified July 14, 2026
Legal status
1P-LSD occupies a legal gray zone in Canada: LSD is listed in Schedule III of the Controlled Drugs and Substances Act as 'lysergic acid diethylamide (LSD), its salts, isomers and salts of isomers', but 1P-LSD is a ring-substituted derivative — not a salt or isomer — is not individually named, and the CDSA contains no general controlled-substance-analogue offence.
Consequences if caught
Because 1P-LSD is not scheduled, possession and (absent misbranding) sale are not CDSA offences; conduct could still draw enforcement if the product is treated as containing or convertible to LSD, or as an unapproved drug under the Food and Drugs Act.
If prescribed or medical
No Health Canada authorisation; handling of scheduled LSD requires a section 56 CDSA exemption, but 1P-LSD itself is unscheduled.
Documentation
Confirmed via the CDSA Schedule III LSD entry (salts and isomers only, with no 'derivatives' or analogue clause); federal scheduling orders through late 2025 (e.g. SOR/2025-243) did not add lysergamide derivatives.
