How to Buy Weed in Chiang Mai: Dispensaries, Prices & Laws (2026)

Is weed legal in Chiang Mai?

Cannabis in Chiang Mai follows Thailand's national framework: since the 2025 re-regulation, it is classified for medical use. The dispensaries that opened after the 2022 decriminalization continue to operate across the city, and access works through a short on-site medical consultation that most tourists complete in minutes. Chiang Mai has long been a center of Lanna (northern Thai) cannabis culture, and the local scene is more mature and better value than the coastal resorts — but treat the legal status as a gray area, not full legalization.

Where to find dispensaries

Chiang Mai's dispensary scene clusters in two areas:

• The Old City (inside the moat) — shops along the main roads like Ratchadamnoen and Moon Muang, often small and owner-operated, with knowledgeable staff and a focus on local flower.
• Nimmanhaemin (Nimman) — the trendy neighborhood west of the Old City, home to higher-end dispensaries, cannabis cafes, and consumption lounges aimed at digital nomads and longer-stay visitors.

You will also find shops near Santitham and along Huay Kaew Road toward the university. The Old City and Nimman options are where quality and honesty are most reliable — the staff here are more likely to discuss strain lineage, terpenes, and lab results than in pure tourist areas.

[!WARNING] Avoid anyone offering cannabis on the street, in night markets (like the Sunday Walking Street), or via tuk-tuk and songthaew drivers. These offers are commonly synthetic cannabinoids, fake product, or involve police. Only buy inside a licensed storefront.

How to buy

Walk into a dispensary and present your passport for the medical certification registration. Staff run a brief consultation, record your details, and issue a cannabis card valid for your stay. You then choose from flower, pre-rolls, edibles, and extracts. Payment is cash (Thai baht); some Nimman shops accept PromptPay QR codes through Thai banking apps, but foreign cards are rarely taken.

Prices and quality

Chiang Mai offers the best cannabis value in Thailand outside of growing regions. Prices run notably lower than Phuket or Bangkok:

• Local Thai flower (including regional landraces): 300–500 THB per gram (€8–13)
• Imported/US genetics: 600–1,000 THB per gram (€16–27)
• Pre-rolls: 150–400 THB
• Edibles and oils: 500–1,200 THB

Seek out Lanna and northern Thai landrace strains — these are the local genetics that gave the world "Thai Stick," and they offer a distinctive uplifting, clear-headed high that is hard to find elsewhere. Reputable Old City shops are your best bet for genuine local product rather than relabeled imports.

Where you can consume

Cannabis consumption is not legal in public under Thai nuisance rules. In Chiang Mai this means:

• Do not smoke in the moat-area streets, temple grounds, or night markets
• Avoid university zones and public parks (Nong Buak Haad, Suan Buak Hat)
• Hotel rooms are the safest option, but check the property's policy first — many Chiang Mai guesthouses and hotels prohibit all smoking including cannabis and will charge cleaning fees
• A few Nimman dispensaries have on-site consumption lounges; ask before you buy

Laws and penalties

• Public consumption carries nuisance fines, typically 5,000–25,000 THB, enforced especially in tourist-heavy Old City zones during festivals (Songkran, Yi Peng).
• Driving under the influence is a serious offense — roadside saliva testing occurs in Chiang Mai, particularly around the Old City and Nimman at night.
• Importing or exporting cannabis through Chiang Mai International Airport is a trafficking offense with severe prison sentences, regardless of medical documentation.
• Keep any possession to small personal amounts (under 30g) and stored discreetly.
