Is Nitrous Oxide legal in Switzerland?
- Legal status
- Nitrous oxide is not a controlled substance under the Narcotics Act (Betäubungsmittelgesetz, SR 812.121); it is regulated as a medical/anaesthetic gas and consumer/food product, while individual cantons (for example Basel-Stadt) restrict its sale or supply for recreational inhalation.
- Consequences if caught
- No federal narcotics penalty applies to possession; cantonal ordinances penalise recreational sale or supply where enacted. No death penalty (non-DP).
- If prescribed or medical
- Nitrous oxide is a lawful medical/anaesthetic gas and food additive; medical and culinary supply is unaffected.
- Documentation
- Cartridges are legally sold for food use nationwide; recreational sale is barred in cantons such as Basel-Stadt.
