GACP and GMP requirements in the production of medical Cannabis flowers in Switzerland
19.11.2025
Switzerland distinguishes clearly between GACP and GMP in the production of medical cannabis. GACP governs cultivation and minimal post-harvest handling, which remain under narcotics law (OCStup) and do not require Swissmedic certification. GMP applies as soon as any pharmaceutical-relevant transformation occurs, triggering LPTh licensing requirements such as extraction, decarboxylation, purification, moisture adjustment, QC testing, and API release. Cultivators operate under OCStup licences, while pharmaceutical manufacturers must hold LPTh establishment licences and comply fully with GMP. This separation ensures a transparent, compliant chain from plant cultivation to medicinal product preparation.
