4-Piperidone Added to Precursor Controls

Summary#

These are final regulations called Regulations Amending the Precursor Control Regulations (Emerging Fentanyl Precursors) that add a specific chemical and some of its variants to the list of controlled precursors under the Controlled Drugs and Substances Act. The change takes effect on the 90th day after publication — that is September 3, 2024.

What it does#

• Replaces part of item 28 in the schedule to the Precursor Control Regulations to list 4‑Piperidone (piperidin-4-one) and its salts, derivatives and analogues.
• Specifically names these examples as included:
  • 1‑boc‑4‑piperidone (tert‑butyl 4‑oxopiperidine‑1‑carboxylate)
  • 3‑methyl‑4‑piperidone (3‑methylpiperidin‑4‑one)
  • 1‑benzyl‑4‑piperidone (1‑benzylpiperidin‑4‑one)
• Says the Regulations come into force on the 90th day after publication in the Canada Gazette, Part II (published June 5, 2024).

Who's affected#

• Companies and people who make, sell, import, export or ship the named chemicals — for example chemical suppliers and distributors.
• Laboratories, universities and manufacturers that use these substances in research or production.
• Law enforcement, customs and public-health groups monitoring fentanyl and related substances.
• If it’s unclear whether a specific product or use is covered, affected parties will need to check the exact chemical names and definitions in the amended schedule.

Why it matters#

• The amendment targets substances identified as linked to fentanyl production (the title calls them “Emerging Fentanyl Precursors”).
• Adding these chemicals to the regulated list means they will be treated differently under Canada’s precursor-control rules, which can affect how they are bought, sold or moved across borders.
• That can make it harder for these chemicals to be diverted into illegal drug production, while also creating new compliance steps for legitimate users.
