How much THC is legal in Switzerland?
It depends on THC content, purpose and the activity involved. Narcotics law applies from 1% total THC. Medical use and authorised trials have specific frameworks. Below 1%, the relevant product rules still apply.
Key facts
- Narcotics law applies from 1% total THC.
- Possession of up to 10 g for personal use is not punishable.
- CHF 100 concerns consumption by adults where the procedure applies.
- Below 1% THC, the rules for the relevant product category still apply.
Detailed answer
Cannabis containing at least 1% total THC is governed by narcotics law. A product below that threshold is not automatically permitted as food, a cosmetic or a medicine. Composition, intended use and the relevant product rules matter. Low THC content is neither a medicine approval nor proof of safety. Non-medical cannabis containing at least 1% THC remains generally prohibited, subject to authorised exceptions. Association membership or the name ‘cannabis social club’ does not create a separate exemption from narcotics law. Products below the THC threshold must also meet their product-specific requirements. Article 8a of the Narcotics Act permits authorised scientific pilot trials. An individual trial may last up to five years, with one extension of up to two years possible on a justified application. This is distinct from the duration of the temporary legal basis. Eligibility, study area and project status must be checked for the particular trial.
Background and legal framework
The Narcotics Act distinguishes consumption, possession for personal use and other activities. Merely holding no more than 10 g for personal consumption is not punishable. This does not generally authorise consumption, dealing or importation. Adult consumption may be handled through a CHF 100 fixed penalty where the conditions for that procedure are met.
Common misconceptions
Cannabis containing at least 1% total THC is governed by narcotics law. A product below that threshold is not automatically permitted as food, a cosmetic or a medicine. Composition, intended use and the relevant product rules matter. Low THC content is neither a medicine approval nor proof of safety.
What this means in practice
The basic rules apply throughout Switzerland. Responsible authorities and enforcement practices can vary between cantons. Without reliable current comparative data, labels such as ‘tolerant’ or ‘strict’ are not dependable legal guidance. The facts and competent authority matter in an individual case; a canton does not change the federal THC threshold.
