Is Nitrous Oxide legal in Canada?

Also known as: laughing gas, whippets, nangs

Legal status

Nitrous oxide sold for inhalation is treated as a drug requiring market authorisation (a DIN) under the Food and Drugs Act and Food and Drug Regulations and may lawfully be administered only by a health professional; it is legal for genuine medical and food (cream-charger) use, but selling it for recreational inhalation is unauthorised. It is not a controlled substance under the CDSA.

Consequences if caught

Health Canada seizes unauthorised inhalation products and works with the CBSA to stop shipments; enforcement is regulatory (unauthorised-drug sale) rather than narcotics-based. No death penalty (non-DP). Section 60 of the Controlled Drugs and Substances Act lets the Governor in Council by order amend any of Schedules I to IV, VI and IX by adding or deleting an item, if the Governor in Council considers the amendment necessary in the public interest. The consolidation read states on its face that it is current to 21 July 2026. An absence is only ever an absence as at the version read, and this cell does not rule out a later amendment.

If prescribed or medical

Nitrous oxide is an approved medical/anaesthetic and dental gas and a food-preparation propellant (E942); those uses are lawful.

Documentation

Cream chargers are sold for food use; products marketed or sold for inhalation lack a DIN and are subject to seizure at the border and at retail.

Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with Canada’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
