The general framework: the Narcotics Act (BetmG) and Article 19b
Cannabis in Switzerland is regulated through the Federal Narcotics Act (Betäubungsmittelgesetz, BetmG; in French, Loi sur les stupéfiants; in Italian, Legge sugli stupefacenti), the federal law that classifies cannabis as a controlled substance nationwide, applied uniformly across all 26 cantons. Unlike Germany, which reformed its law in 2024 to regulate adult use, Switzerland has not legalized recreational cannabis at national level — but since 2013 it has applied a partial decriminalization mechanism that sets it apart from most of its neighbours.
Since 1 October 2013, Article 19b of the BetmG decriminalizes possession of up to 10 grams of cannabis for personal use by adults: instead of criminal proceedings, police can directly issue a fixed fine of CHF 100, with no criminal record. Above that quantity, possession becomes a criminal offence again, and cultivation, sale and trafficking — whatever the quantity — remain crimes under Article 19 of the same law.
Switzerland doesn't fit into any of the usual categories on Europe's legal map: it isn't judicial tolerance like Spain, it isn't gedoogbeleid like the Netherlands, it isn't statutory legalization like Germany. It's its own model of administrative decriminalization combined with regulated-sale pilot trials, explicitly designed as a scientific test phase ahead of eventual national legalization.
Possession and consumption: the fixed CHF 100 fine
For an adult found with up to 10 grams of cannabis intended exclusively for personal use, the practical consequence is simple and predictable: police issue a fixed fine (Ordnungsbusse) of CHF 100, with no need to open judicial proceedings or generate a criminal record. This mechanism, in force since October 2013 under Article 19b of the BetmG, makes Switzerland one of the few European countries with an explicit administrative procedure applied uniformly for possession of small quantities.
It's worth clarifying that this decriminalization applies strictly to possession and one-off consumption: mere possession of up to 10 grams for personal use is not punishable in itself if there is no active consumption, but the act of consuming cannabis does trigger the CHF 100 fine as a one-off administrative offence. Above 10 grams, even if the stated purpose is personal use, the conduct becomes punishable under the law's general criminal framework.
An adult with a reasonable quantity for personal consumption doesn't face criminal proceedings or a criminal record: they receive an administrative fine comparable to a minor traffic offence. However, this is not the same as legalization: the substance remains illegal, and selling, cultivating, or possessing larger quantities carries real criminal consequences, including prison sentences in the most serious cases.
Home cultivation: banned for THC, allowed only for hemp
Unlike Germany (up to 3 legal plants under the CanG) or the de facto tolerance of the Netherlands, current Swiss legislation does not allow growing cannabis with THC content at home, not even for strictly personal use — this includes any cannabis variety whose THC content exceeds 1%, the threshold Swiss law uses to distinguish legal hemp from narcotic cannabis.
What is legal, under certain cantonal conditions, is growing low-THC hemp (below 1%). Under the 2012 Concordat on Hemp Cultivation and Trading (Konkordat über den Hanfanbau und -handel), residents of seven cantons — including Geneva and Basel — may grow up to four hemp plants from seed, always for personal use and always below the legal THC threshold. This authorization does not, under any circumstances, permit growing cannabis varieties with THC above 1%.
In August 2025, the Swiss Parliament's Social Security and Health Committee submitted a draft Federal Cannabis Products Act (CanPG) for public consultation, with parliamentary review scheduled for spring or summer 2026. This proposal would allow adults to grow up to three female cannabis plants for personal use at home — a significant change from the current framework, but for now it remains only a legislative proposal, not a law in force.
The pilot trials: Switzerland's unique feature in Europe
This is, without a doubt, the element that most sets Switzerland apart from the rest of Europe: since 2023, the Federal Office of Public Health (FOPH/BAG) has authorised seven scientific pilot trials for regulated adult-use cannabis sales, operating in Basel-Stadt, Bern, Biel, Lausanne, Lucerne, Vernier and the city of Zurich, with combined enrolment around 10,400–10,500 registered participants.
The first project launched in Basel-Stadt at the end of January 2023. Zurich followed with the "Züri Can" project in August 2023, later expanded with a second project covering the entire canton of Zurich (including Winterthur) since May 2024. Züri Can is currently the largest of these trials: it has 2,456 admitted participants and has processed roughly 106,000 sales. The project was originally scheduled to end in autumn 2026, but the city of Zurich has already received approval to extend it to 2028. St. Gallen has more recently joined with its own pilot trial.
These are not "cannabis social clubs" in the Spanish style, nor coffeeshops in the Dutch style: they are scientific studies authorised by the federal government, with mandatory enrolment, health monitoring of participants, and sales through controlled channels — pharmacies, non-profit cannabis social clubs and specific stores. One of the ten social clubs participating in the Zurich project, called "Hanfstübli", operates in direct collaboration with the city council.
Preliminary results from these trials, based on data available to date, show positive outcomes: no increase in consumption has been observed among the general population, participants show a trend toward lower-risk consumption patterns, and no significant negative impacts on physical or mental health have been detected among enrolees. This is precisely the data the federal government will use to design the definitive legal framework that will replace the pilot trials.
Trafficking and sale: Article 19 of the BetmG
Outside the framework of authorised pilot trials, selling and trafficking cannabis in Switzerland is prosecuted under Article 19 of the BetmG, which punishes these conducts with imprisonment of up to three years or a monetary penalty for cases considered a misdemeanour. Professional cannabis trade, as well as possession of a quantity capable of endangering the health of a large number of people — set, for practical purposes, at around 4 kilograms of hashish — is punished with one to three years of imprisonment, which can be combined with an additional fine.
Penalties increase significantly in cases of organised trafficking, involvement of minors, or links to organised crime structures, where sentences can substantially exceed the three-year reference for the basic offence. Giving away cannabis, even without profit motive, is also considered a form of "supply" (Weitergabe) punishable under the same Article 19, outside the authorised pilot trials.
Cannabis and driving: de facto zero tolerance
Switzerland applies one of the strictest regimes in Europe regarding driving under the influence of cannabis: a person is considered unfit to drive from 1.5 nanograms of THC per millilitre of blood, a threshold so low it amounts, in practice, to zero tolerance.
If that 1.5 ng/ml value is exceeded, it is automatically presumed the driver is unfit to drive, with no need to demonstrate objective signs of impairment — driving errors, unsafe behaviour — and regardless of how the person subjectively feels. Since THC can remain detectable in the blood of regular consumers even days after last use, this regime can affect people who no longer experience any real psychoactive effect at the time of the check.
There is an exception for medical cannabis: Article 2, paragraph 2ter of the Traffic Admission Ordinance (VZV) states that zero tolerance does not apply when the THC comes from a doctor-prescribed medicine. Even so, people taking cannabis on medical prescription are not automatically considered fit to drive: participation in motorised traffic should only occur after a positive assessment by a traffic medicine specialist.
Medical cannabis: the August 2022 reform
Since 1 August 2022, any licensed doctor in Switzerland can prescribe cannabis-based medicines — flowers, resins, extracts, oils and tinctures for medical purposes — without needing to request the special authorization previously required from the Federal Office of Public Health (FOPH/BAG). This reform reclassified medical cannabis, moving it from a prohibited narcotic to a controlled narcotic within the Narcotics List Ordinance.
Until 2022, medical use was only permitted in exceptional circumstances, following a successful application by the prescribing doctor to the FOPH: on average, around 3,000 exceptional authorisations were granted per year, mainly for patients with cancer, multiple sclerosis or other neurological illnesses. Since August 2022, any doctor can prescribe directly, and patients can collect their medication at pharmacies with no additional procedures.
Despite this regulatory advance, real access remains unequal: prices for cannabis-based medicines remain high, and prescribing doctors' interest remains limited, according to Swiss patient associations, which in 2025 continued to call for improvements in real access — not just the legal framework — ahead of the next reform phase.
CBD in Switzerland: the 1% THC limit
Switzerland set, as early as 2011, a legal threshold for CBD notably more permissive than the rest of Europe: products with a THC content below 1% are not considered narcotics under Swiss law. This contrasts with the usual 0.2%-0.3% limit applied by most European Union countries, making so-called Swiss "CBD cannabis" or "cannabis light" a legal product with a considerably higher THC concentration than its equivalents in France, Germany or Spain.
Products with less than 1% THC — dried hemp flowers, extracts, capsules, oils, vape liquids and topical products — are openly sold in Swiss specialist shops, tobacconists and online retailers. According to Swissmedic's 2024 report, both isolated CBD and broad-spectrum extracts are permitted without additional restriction, while full-spectrum products must strictly stay below the 1% THC threshold to remain legal.
Use of cannabis with a THC content of 1% or higher is, by contrast, generally prohibited in Switzerland — which is why staying below that threshold is the determining criterion for a product to be considered legal CBD rather than narcotic cannabis.
The Cannabis Products Act (CanPG): the road to 2029
Unlike the United Kingdom, Switzerland has an explicit legislative roadmap toward national cannabis legalization — though not yet approved. Under the current timetable, the new Cannabis Products Act (Cannabis-Produktegesetz, CanPG) could enter into force, at the earliest, in 2029: the scientific pilot trials will be extended until 2028 precisely to generate the evidence that will serve as a solid basis for parliamentary debate.
The draft establishes that any person over 18 residing in Switzerland could grow (up to three female plants), buy, possess and consume cannabis. Unlike the free-market model adopted in some North American states, the Swiss proposal opts for a centralised distribution model, with strict advertising restrictions, mandatory age checks at point of sale, mandatory information at distribution points, and a strict ban on consumption near schools or youth centres.
It's important to be precise about the real status of this reform: as of July 2026, the CanPG remains a legislative draft under consultation and parliamentary review, not a law in force. The planned timetable envisages parliamentary review during spring or summer 2026, with eventual entry into force subject to that legislative process and the final evaluation of the pilot trials in 2028.
Switzerland compared to the rest of Europe
Compared to its European neighbours, Switzerland combines elements found nowhere else together on the continent: straightforward administrative decriminalization, a much more generous THC limit for CBD, and the only large-scale regulated-sale pilot trial system in Europe.
Switzerland — decriminalization + pilot trials
Fixed CHF 100 fine for possession up to 10g, no national legalization, but ~10,500 participants in regulated-sale trials unique in Europe. National legalization expected, at the earliest, in 2029.
Germany — statutory regulation (CanG)
Since 2024, an explicit law regulates possession, home cultivation up to three plants, and cultivation associations with official registration.
Netherlands — regulated tolerance (gedoogbeleid)
Sales tolerated in coffeeshops under AHOJGI criteria, though wholesale cultivation remains formally illegal.
Spain — judicial tolerance
No specific law: private consumption is tolerated for lack of criminal relevance, and cannabis clubs rest on Supreme Court case law.
The core difference is clear: while Germany legislated directly and the Netherlands built its tolerance over decades of administrative practice, Switzerland has opted for an explicitly experimental middle path — using scientific pilot trials, supervised and with enrolled participants, as a mandatory prior phase before legislating nationally. Of the three major European regulatory models, it's the most cautious in its methodology, but also the only one that already combines real decriminalization of possession with a legal sales market today — although limited to study participants, not open to the general public.

Practical checklist
- Don't confuse decriminalization with legalization — the fixed CHF 100 fine for possession up to 10g doesn't mean cannabis is legal in Switzerland; it remains a controlled substance.
- Don't grow cannabis with THC at home — only hemp with less than 1% THC is allowed, and only up to 4 plants in seven specific cantons under the 2012 Concordat.
- If you want to access the pilot trials, check first whether your city participates — Basel-Stadt, Bern, Biel, Lausanne, Lucerne, Vernier, Zurich (and St. Gallen) are, for now, the only places with legal regulated sales for enrolled participants.
- Never drive after consuming cannabis — the 1.5 ng/ml THC threshold amounts to de facto zero tolerance, and THC can be detectable days after consumption in regular users.
- If you need medical cannabis, ask your doctor directly — since August 2022 any licensed doctor can prescribe it, with no special FOPH procedures.
- When buying CBD, verify the THC is below 1% — the Swiss limit is higher than the usual 0.2%-0.3% in the EU, but it's still a strict legal limit.
- Don't assume national legalization is a done deal — the Cannabis Products Act (CanPG) remains, in 2026, a draft under parliamentary review, with entry into force expected, at the earliest, in 2029.
- Remember that trafficking and sale outside the authorised trials remain a crime — with sentences of up to 3 years imprisonment, aggravated in cases of organised crime or large quantities.
Frequently asked questions about cannabis in Switzerland
It's not legalized at national level, but possession of up to 10 grams for personal use has been decriminalized since 2013: instead of criminal proceedings, police issue a fixed CHF 100 fine. Above that quantity, possession, cultivation and sale remain crimes under the Narcotics Act (BetmG).
They are scientific studies authorised by the Federal Office of Public Health (FOPH/BAG) that allow regulated cannabis sales to enrolled participants in seven cities and cantons — Basel-Stadt, Bern, Biel, Lausanne, Lucerne, Vernier and Zurich — with about 10,500 participants total. They are not legal for the general public: they require prior enrolment and health monitoring.
Not if it contains THC above 1%: home cultivation of narcotic cannabis is banned outside the pilot trials. It is legal to grow low-THC hemp (below 1%) up to four plants in seven specific cantons, under the 2012 Concordat. A draft reform (CanPG) proposes allowing up to three THC cannabis plants for personal use, but it's not yet law in force in 2026.
1% THC, a threshold set since 2011 and notably higher than the usual 0.2%-0.3% in the European Union. Products below that threshold — hemp flowers, extracts, oils, vape liquids — are legally sold in Swiss specialist shops and tobacconists.
A de facto zero tolerance applies: from 1.5 nanograms of THC per millilitre of blood, you're presumed unfit to drive, with no need to show signs of impairment. There's an exception for those taking cannabis on medical prescription, but even then a positive assessment from a traffic medicine specialist is required before driving.
Yes. Since 1 August 2022, any licensed doctor can prescribe cannabis-based medicines without special FOPH authorization, and patients can collect them directly at pharmacies. Before that reform, an exceptional application had to be approved case by case, with about 3,000 authorisations granted per year.
There's no confirmed date. The Cannabis Products Act (CanPG) is, in 2026, a draft under public consultation and parliamentary review, with pilot trials extended until 2028 to gather scientific evidence. Under the current legislative timetable, full national legalization is realistic, at the earliest, in 2029 — and could be delayed beyond that date.
Up to 3 years imprisonment or a monetary penalty for the basic offence under Article 19 of the BetmG. Possession of quantities capable of endangering the health of a large number of people — a reference point of around 4 kilograms of hashish — or organised trafficking can carry considerably harsher sentences.
Swiss pilot trials are designed for enrolled residents who meet the study criteria in their corresponding city or canton, with ongoing health monitoring; they are not designed as a service open to passing tourists. This guide doesn't cover the exact enrolment requirements of each pilot project in detail; it's advisable to check the relevant project's page directly (for example, Züri Can in Zurich) before attempting to enrol.
