Growing Cannabis in Switzerland — what's legal

In Switzerland, cannabis varieties under 1% THC (CBD hemp) are legal for home growing — with some cantonal obligations. Anything above is criminal. Medical self-cultivation is technically possible but very rare.

CBD hemp (<1% THC): legal home growing, cantonal notification often required beyond hobby scale. THC (>1%): illegal, a few plants suffice to be convicted. Medical self-cultivation: theoretical via Swissmedic, almost never granted. Legal alternatives: CBD flower, medical prescription, pilot projects.

CBD hemp (<1% THC) — what's allowed

Cultivation of varieties <1% total THC is legal (NarcA Art. 8 para. 5 + BetmVV-EDI annex 6). No quantity limit for personal use.

Some cantons require notification beyond hobby scale (~10 plants or outdoor). EU-certified genetics recommended.

THC cannabis — quick costs

THC cultivation (>1%): NarcA Art. 19. Even one plant can trigger 'manufacture of narcotics'. Fine or prison.

Above ~4 kg THC or in a gang: serious case, up to 20 years. Grow-box = almost automatically 'professional' cultivation.

Medical self-cultivation — the exception

Theoretically possible via Swissmedic, in practice almost never granted. Realistic path: classic prescription at the pharmacy.
