Is weed legal in Cancún? Not to buy, sell or carry around freely. Mexico has no legal cannabis sales. Under the Ley General de Salud, prosecutors shall not prosecute a user found with up to 5 grams for strict personal use, but that is a limit on prosecution, not a right to buy. Possession above it, or anywhere near schools and similar places, can be a crime. A 2021 Supreme Court ruling opened the door to permits for personal use, but it explicitly bars commercial sale (SCJN).
The short version
- No legal sales in Cancún, whatever a beach vendor says.
- 5 g is the personal-use threshold for cannabis in the law's table. At or below it, the prosecutor shouldn't press charges against a consumer. Above it, possession can mean prison (DOF).
- Selling or supplying, even for free, is a crime with prison time.
- The 2021 Supreme Court ruling allows health-authority permits for adults to grow and consume cannabis themselves. It does not allow selling, supplying or importing.
- Fake police and extortion are real risks for visitors (FCDO).
Law vs. practice
Mexico's small-scale drug rules (narcomenudeo) sit in Chapter VII of the Ley General de Salud. They were added by a 2009 decree published in the Diario Oficial (DOF):
- Art. 479: a table of maximum doses for "strict and immediate personal consumption". For cannabis it's 5 g.
- Art. 478: the public prosecutor shall not prosecute a consumer or dependent user who has an amount at or below the table, for strict personal use, outside the places listed in Art. 475 (schools, care facilities, police stations, prisons, and within 300 m of them). The prosecutor must also tell the person where to find treatment or prevention services and report the case to health authorities.
- Art. 477: possession above the table (but below 1,000×), when it isn't for sale, means 10 months to 3 years in prison.
- Arts. 475–476: selling or supplying, even for free, means 4 to 8 years; possession for sale, 3 to 6 years.
The Supreme Court ruling. In June 2021 the Supreme Court (SCJN) struck down, with general effect, the ban on authorising recreational self-consumption. The health authority (through COFEPRIS) can now authorise adults to grow, harvest, prepare, possess and transport cannabis for their own use. It cannot authorise importing, selling, supplying or any other distribution, and use must not affect third parties, minors or non-consenting people in public (SCJN).
What this means for a tourist: there's no lawful source. Any "dispensary" or vendor selling to you is outside the law, and so is the purchase.
Penalties
| Situation | Penalty under the Ley General de Salud |
|---|---|
| Up to 5 g, personal use, not near the listed places | No prosecution; referral to health or treatment services |
| More than 5 g (below 1,000×), not for sale | 10 months – 3 years |
| Possession with intent to sell or supply | 3 – 6 years |
| Selling or supplying (even free) | 4 – 8 years; higher near schools or if minors are involved |

Border & airport rules
- Never bring cannabis into Mexico, and never take it out. The SCJN ruling expressly excludes importing (SCJN).
- Don't carry anything for anyone. Trafficking charges carry very long sentences.
- CBD: the rules for bringing CBD products into Mexico aren't clearly published by official sources. The safe choice is to leave them at home.
- Medicines with controlled substances: carry the prescription. Article 477 says possessing medicines that contain listed narcotics isn't prosecuted when the type and amount match the treatment of the person carrying them (DOF).
Legal options
For visitors, effectively none. The only legal route is a COFEPRIS self-consumption permit following the SCJN ruling, and that's designed for adults growing for themselves, not for tourists or buying.
Culture & etiquette
Smoking on beaches, at resorts or in the street can lead to police contact, complaints or worse, and being near schools and similar places takes you out of the 5 g protection. The best choice is not to use cannabis there at all.
Scams to watch for
From the UK government's Mexico advice (FCDO):
- Fake police who try to fine or arrest visitors, often targeting rental-car drivers.
- Genuine police extortion over alleged minor offences.
- "Virtual kidnapping" phone scams, where callers claim a relative has been kidnapped or detained and demand money.
- Drink and food spiking, followed by robbery or assault.
The FCDO is blunt: "Do not become involved with drugs of any kind." Drug-related violence has increased in Mexico.
Harm reduction & if things go wrong
- Emergencies: 911.
- If police stop you, stay calm, ask for the officer's name and badge number, and ask for any fine in writing, payable at an official office.
- If you're detained, ask for your consulate and a lawyer, and don't sign anything you don't understand.
- Watch your drinks and your food.
- Never buy from strangers. Counterfeit and contaminated drugs are a real risk.
