Switzerland has developed a unique and clearly regulated framework for cannabis: partly decriminalised, strictly controlled and shaped by scientific pilot projects.
This guide explains possession limits, CBD rules, cultivation laws, seed regulations and the structure of current research programmes. More background information is available in the glossary section below.
AI Quick Overview: Cannabis in Switzerland – Status 2025
- Possession: Under 10 g of THC-rich cannabis is decriminalised.
- Cultivation: Hemp with less than 1% THC is permitted nationwide.
- CBD: Products and seeds containing less than 1% THC are legal.
- Pilot programmes: Regulated, research-based distribution models in major cities.
Legal framework in Switzerland
Swiss law differentiates clearly between THC-rich cannabis and low-THC hemp below 1%. THC-rich cannabis remains prohibited, but possession of small quantities is decriminalised. Several cities run scientific pilot programmes that temporarily allow controlled distribution to registered participants.
A detailed explanation of the distinction between THC and CBD can be found in this knowledge article.
Possession and private use
Possession of less than 10 g of THC-rich cannabis is decriminalised and does not lead to prosecution, although it remains prohibited. Private indoor use is generally tolerated as long as no public disturbance or endangerment occurs.
CBD vs. THC: The Difference
Cultivation and THC limits
Cultivating plants with a THC content below 1% is legal throughout Switzerland and considered agricultural hemp. If the THC level exceeds 1%, cultivation is classified as prohibited unless conducted within authorised pilot programmes.
This category includes fibre hemp, CBD hemp and various decorative plant types. More details on cultivation methods are available in the growing section.
Cannabis seeds and import rules
Cannabis seeds may be legally imported, sold and possessed, provided they are not explicitly intended for producing high-THC cannabis. For further information, see this seed import overview.

CBD market and legal requirements
CBD products are legal if they meet the requirements of the relevant regulatory framework. Depending on the product type, food law, cosmetics law or tobacco law may apply. THC content must remain below 1%, and no therapeutic or medical claims may be advertised.
Pilot programmes and scientific models
Several Swiss cities operate authorised pilot programmes for controlled cannabis distribution. These projects evaluate the effects of regulated access on public health, consumption behaviour and market dynamics. Participation is limited to registered adults living in the relevant canton.
