Can you smoke weed in public in Chiang Mai? It’s one of the first things visitors ask once they see how many cannabis shops line the Old City streets. The answer surprises many people: buying from a licensed shop is one thing, but lighting up on the street, in a park or at a night market is not allowed. This guide explains where you can’t smoke, why, and how to stay on the right side of the rules in Chiang Mai.
No. Thailand removed cannabis from its narcotics list in 2022, but it never made public smoking legal. The Ministry of Public Health classed cannabis smoke and smell as a public nuisance under the Public Health Act. If your smoke or smell bothers people around you, you can face up to 3 months in jail, a fine of up to 25,000 baht, or both.
Since 2025, the rules have become stricter, not looser. Cannabis flower is now a controlled herb, and licensed shops can only sell it with a valid prescription. For the full picture, read our Thailand cannabis laws 2026 guide for foreign tourists.
Some places ban smoking of any kind, not just cannabis. Others fall under the public nuisance rule because they are busy and shared. As a simple guide:
| Place | Can you smoke cannabis there? | Why |
|---|---|---|
| Temples and their grounds | No | Religious sites are smoke-free and deeply respected |
| Night markets and walking streets | No | Crowded public spaces; markets are no-smoking areas |
| Schools, hospitals, government buildings | No | Smoking is banned by law |
| Parks, the Old City moat, public squares | No | Public places where smoke can be a nuisance |
| Bars, cafes and restaurants | Usually no | Indoor smoking is banned; most venues don’t allow cannabis |
| Hotel rooms and balconies | Only if the property allows it | House rules apply and many hotels ban smoking |
| Private home or villa with the owner’s permission | Generally yes | Private space, as long as smoke doesn’t bother neighbours |
The safest rule is simple: if other people can see or smell it, don’t do it.
No, and this matters more in Chiang Mai than almost anywhere else. The Old City has more than 30 temples within its walls, and many sit right beside guesthouses, cafes and shops. Smoking on or near temple grounds is both against the rules and deeply disrespectful to monks and worshippers.
Keep well away from temples, and remember that many Old City lanes have a temple at one end. Our guide to cannabis etiquette for foreigners in Thailand covers other cultural points worth knowing.
No. Chiang Mai’s walking streets and night markets are packed with families, children and food stalls, and markets are no-smoking areas. Smoking cannabis there is very likely to bother people around you, which is exactly what the public nuisance rule targets.
Enjoy the markets as markets. If you want to visit a licensed shop on the way, buy what you need and take it back to a private place where you’re allowed to use it.
Only if the property allows it. Many hotels and guesthouses in Chiang Mai ban smoking of any kind in rooms, and some charge a cleaning fee if they find smoke damage. Others have a designated outdoor smoking area, but that doesn’t always cover cannabis.
Ask at reception or check the house rules before you book. Our guide to cannabis in hotels and Airbnbs in Chiang Mai explains what to look for and how to ask politely.
In most cases, police or officials will ask you to stop, and you may receive a fine. If people complain, or you smoke in a banned place, the penalties can be more serious. The public nuisance rule allows for:
Separate rules apply to driving. Never ride a scooter or drive after using cannabis. Our article on cannabis while scootering in Thailand explains why.
The general rule is private places where the owner allows it. That usually means a private home, villa or condo, or accommodation that clearly permits cannabis use. Even there, keep smoke away from neighbours and shared areas such as hallways and pools.
