Is Heroin legal in Switzerland?

Confirmed against a primary sourceVerified June 25, 2026
Legal status
Prohibited narcotic under the BetmG (SR 812.121) — production, import and sale criminal
Consequences if caught
Switzerland's four-pillar policy (prevention, therapy, harm reduction, repression — enshrined 2011) shapes enforcement: drug USE is punishable by a fine (Art 19a); heroin-assisted treatment (diamorphine on prescription) is legal for dependent patients; and supervised consumption rooms and official drug-checking services operate in several cities. Trafficking, supply or manufacture (Art 19) carries up to 3 years or a fine; aggravated cases (Art 19 para 2 — endangering many people, roughly 4 kg of hashish, or organised activity) carry 2–10 years. Heroin is a prohibited hard drug.
If prescribed or medical
Heroin itself is prohibited, but heroin-assisted treatment (diamorphine on prescription) is legal for dependent patients within the federal programme; carry any Schengen Article 75 certificate for prescribed narcotics (see documentation).
Documentation
Schengen travel: carry prescribed narcotics with a Schengen Article 75 certificate and keep them in original packaging. Medical cannabis has been prescribable by doctors WITHOUT a special FOPH permit since August 2022.
