Growing Cannabis in Switzerland — What is Legal
In Switzerland, cannabis strains with less than 1% THC (CBD hemp) are legal for home cultivation — subject to certain cantonal regulations. Anything above this limit is a punishable offence. Medical home cultivation is theoretically possible, but extremely rare in practice.
TL;DR: CBD hemp (<1% THC): Legal to grow at home, often requires cantonal notification, no quantity limit for personal use. THC cannabis (>1%): Illegal; even a few plants can be considered 'cultivation in significant quantities' and lead to multi-year prison sentences. Medical home cultivation: Theoretically possible with a Swissmedic exemption permit, but almost never granted in practice. Legal alternatives: Buying CBD flowers, obtaining a medical prescription, or participating in a pilot project.
Growing CBD Hemp (<1% THC) — What is Allowed
The cultivation of cannabis strains with less than 1% total THC is generally legal in Switzerland. The legal basis is Art. 8 Para. 5 of the Narcotics Act (BetmG) in conjunction with Annex 6 of the BetmVV-EDI. There are no quantity restrictions for private home cultivation.
In practice: Some cantons (especially agricultural ones) require notification to the cantonal agricultural office or the FOAG (BLW) if cultivation exceeds 'hobby' levels (rule of thumb: from 10 plants or for outdoor areas). Certified EU variety catalogue genetics are recommended (Finola, Futura 75, etc.) — for non-certified strains, a laboratory certificate per batch is required.
Important: The 1% limit also applies during cultivation. Anyone who cultivates 'CBD genetics' that ultimately produce 1.2% THC has legally produced a narcotic — even if unintentionally. Therefore, test every new genetic strain (see our deep dive on the 1% THC limit).
Growing THC Cannabis — Why it Quickly Becomes Expensive
The cultivation of THC cannabis (>1%) is a punishable offence under Art. 19 of the Narcotics Act (BetmG). Even a single indoor plant yielding ~50g can be prosecuted as the 'manufacture of narcotics' — resulting in a fine or imprisonment.
From around 4 kg of pure THC yield or in cases of gang-related cultivation, it is considered a 'serious case' (Art. 19 Para. 2 BetmG) with penalties of up to 20 years. Grow boxes or complete setups almost automatically lead to charges of 'commercial' cultivation — even if no sale was intended.
Consequences in addition to the penalty: Confiscation of the equipment and devices, repayment of the 'achievable revenue' (even if not sold), and potentially the termination of your rental agreement (apartment).
Medical Home Cultivation — The Exception
Theoretically, Swissmedic can grant exemption permits for medical home cultivation under Art. 8 Para. 5 BetmG. In practice, these are almost never issued — requirements include a medical certificate, a documented therapy-resistant illness, and proof that standard preparations are unavailable or ineffective.
A more realistic path: A classic cannabis prescription from a doctor, dispensed at a pharmacy. Find details in our guide 'Cannabis Prescription Switzerland'.
Legal Alternatives to Home Cultivation
1) Buy CBD flowers (ready cultivated, under 1% THC): from 1–2 CHF/g wholesale, 5–8 CHF/g in retail.
2) Medical cannabis prescription (>1% THC legal): 10–15 CHF/g in pharmacies, medical consultation required.
3) Pilot project participation (Zurich, Bern, Basel, Lausanne, Geneva, Lucerne, Winterthur): Regulated THC cannabis for study participants. Details in the pilot project hub.
4) CannabisClub.ch: Collective access to CBD at producer prices, preparing for THC access as soon as regulation arrives.
FAQ
Is home cultivation of cannabis legal in Switzerland?
CBD hemp (<1% THC): Yes, with cantonal notification above hobby quantities. THC (>1%): No, it is a punishable offence.
How many CBD plants can I grow at home?
There is no strict limit for personal use. From ~10 plants or for outdoor areas: Notification to the canton is recommended.
What happens if my CBD plant exceeds 1% THC?
Legally, it becomes a narcotic — even without intent. Therefore, have every new genetic strain tested (80–150 CHF).
Can I grow medical cannabis myself?
Theoretically, with a Swissmedic exemption permit — but in practice, it is almost never granted.
What is the penalty for a few THC plants at home?
Even 1–3 indoor plants can be prosecuted as the 'manufacture of narcotics'. This can result in a fine or imprisonment, and confiscation of the equipment.
