| Jurisdiction | Status | Rule | |
|---|---|---|---|
| California, USA | Legal | 28.5 g flower / 8 g concentrate Adults 21+ may possess up to 28.5 g of cannabis flower and 8 g of concentrate. Possession on federal lands (national parks, federal buildings) remains illegal regardless of state law. Consumption in public places is prohibited and typically fined. |

| Colorado, USA | Legal | 1 oz (28 g) Adults 21+ may purchase and possess up to one ounce (28 g) of cannabis; registered medical patients have higher limits. Public consumption is prohibited and can be fined. Possession on federal land within Colorado remains a federal offense. |

| New York, USA | Legal | 3 oz flower / 24 g concentrate Adults 21+ may possess up to 3 oz of cannabis flower and 24 g of concentrate; at home, larger personal amounts stored securely are allowed. Smoking cannabis is generally permitted wherever tobacco smoking is allowed, with exceptions such as parks, schools and cars. Possession above the limits can still be charged. |

| United States (federal) | Illegal | Federally illegal Cannabis remains a Schedule I controlled substance under federal law, so possession is a federal offense even in states that have legalized it. A rescheduling review toward Schedule III has been underway since 2024 but has not been completed — verify current status. In practice, federal enforcement targets trafficking rather than state-compliant consumers. |

| Canada | Legal | 30 g public possession Adults may carry up to 30 g of dried cannabis (or the legal equivalent in other formats) in public. Possession over the limit in public is a criminal offense, though there is no limit on the amount kept at home in most provinces. Provinces may add rules on where cannabis can be carried or consumed. |

| Germany | Legal | 25 g public / 50 g home Since the Cannabis Act (CanG) took effect in April 2024, adults 18+ may possess up to 25 g in public and 50 g at home. Consumption is prohibited within 100 m of schools, playgrounds, youth facilities and sports grounds, and in pedestrian zones during morning hours. Amounts above the limits remain a criminal offense. |

| Malta | Legal | 7 g legal Adults 18+ may possess up to 7 g of cannabis legally since Malta's 2021 reform — the first of its kind in the EU. Amounts between 7 g and 28 g bring fines without a criminal record; larger amounts remain criminal. Public consumption is prohibited and fined, with higher penalties near minors. |

| Netherlands | Decriminalized | Up to 5 g tolerated Possession of up to 5 g of cannabis is tolerated: police will usually not prosecute, though they may confiscate it. Amounts between 5 g and 30 g can bring fines, and possession above 30 g is treated as a criminal offense. Cannabis remains an illegal soft drug under the Opium Act — the policy is non-prosecution, not legalization. |

| Portugal | Decriminalized | Decriminalized small amounts Portugal decriminalized personal possession of all drugs in 2001: up to a 10-day personal supply of cannabis (defined as 25 g of flower or 5 g of hashish) is an administrative matter handled by dissuasion commissions, not a crime. Repeat or larger amounts can bring fines or treatment referrals. Trafficking and cultivation for sale remain criminal offenses. |

| Spain | Decriminalized | Private use decriminalized Consumption and possession of cannabis in private spaces are not criminal offenses in Spain. Public consumption or possession is an administrative infraction carrying fines starting at several hundred euros under the public-security law. There is no legal quantity threshold — the context (private vs public) is decisive. |

| Switzerland | CBD only | Small amounts decriminalized Adults caught with under 10 g of cannabis face a fixed fine (CHF 100) rather than criminal prosecution, a regime in place since 2013. Cannabis with 1.0% THC or more remains a narcotic under the BetmG, so possession above the small-amount threshold can still be prosecuted. Consumption itself can also be fined, and cantons apply the rules with some local variation. |

| Thailand | In flux | In flux Cannabis was delisted as a narcotic in 2022, broadly permitting possession, but the legal framework remains in flux. The government has repeatedly proposed re-regulation — including restricting use to medical purposes with a prescription — and draft rules have changed several times. Verify the current ministerial regulations before acting on any summary. |

| United Kingdom | Medical only | Recreational possession illegal Cannabis is a Class B drug under the Misuse of Drugs Act 1971. Possession can lead to arrest, with maximum penalties of up to 5 years in prison, an unlimited fine, or both; in practice police often issue warnings or penalty notices for small first offenses. Supply and production carry maximum penalties of up to 14 years. |

| Uruguay | Legal | Legal for registered residents Uruguay legalized cannabis for adult residents in 2013, but access is tied to registration: users must be Uruguayan citizens or permanent residents, 18+, and enrolled in the IRCCA registry. Registered users may obtain up to 40 g per month and must choose a single legal channel — pharmacy, club or homegrow. Tourists cannot legally purchase cannabis. |
