Is cannabis legal in Mexico?

No. Legal cannabis in Mexico, in the sense understood in Canada or certain US states, does not exist. There are no dispensaries, clubs, or authorized shops. However, the country is no longer in a state of pure prohibition: its judges have dismantled it, without lawmakers stepping in to take over. At Tealer420, we see travelers every year convinced that cannabis in Mexico is sold perfectly legally in Tulum. This is false, and it can be very costly. Here is what is permitted, tolerated, or punished.

Cancún, Tulum, Playa del Carmen: the mirage of the shops

This is the image that misleads the most people. In the tourist areas of the Riviera Maya, you come across shops that sell cannabis almost openly. They are not legal. In Mexico, the commercialization, distribution, supply, and sale of cannabis remain completely prohibited, without exception.

Buying, even in a storefront, therefore remains illegal. And the risk is not limited to the law: cases of extortion by police officers targeting tourists shortly after purchasing from illegal sellers are documented. Some of these shops are also reportedly linked to organized crime, according to several sources.

The rule of thumb is simple: if someone sells you cannabis in Mexico, they are acting illegally, and so are you.

Cannabis in Mexico: why it is neither legal nor forbidden

To understand this hybrid status, you have to follow the tug-of-war between the Supreme Court (SCJN) and Congress.

In February 2019, the SCJN established a legal precedent: totally banning recreational use violates the right to free development of personality. It ordered Congress to legislate. In 2021, it went further with a general declaration of the unconstitutionality of the absolute ban. Congress, however, has still passed nothing.

The result is a country stuck between two eras: absolute prohibition no longer exists, but no market has replaced it. As of September 24, 2026, the Sheinbaum government had not announced any regulatory law. Of the three countries hosting the 2026 World Cup, Mexico is the only one without full cannabis regulation.

5 grams: the line not to cross

The figure to keep in mind is 5g. That is the amount the General Health Law considers intended for personal and immediate consumption. Below that, the public prosecutor should not bring charges.

Above that, with no evidence of trade, you shift into the offense of simple possession: 10 months to 3 years in prison and up to 80 days of fines.

This threshold almost disappeared. On February 4 and 5, 2026, the First Chamber of the SCJN deemed its automatic nature unconstitutional in a case involving 14.26g. The vote was 5 to 4, whereas 6 votes were required for the decision to be binding nationwide. A judge can therefore assess the situation on a case-by-case basis, but the decision remains individual and the practices of public prosecutors remain uncertain.

One final point, often forgotten: even with less than 5g, the police can seize and check at their discretion. No prosecution does not mean no trouble.

Growing with a permit: the only legal path

There is only one way to grow and consume within the rules in Mexico: obtain a health authorization from COFEPRIS. It allows, for personal consumption, the sowing, growing, harvesting, preparing, possessing, and transporting of cannabis. It is reserved for adults.

On June 25, 2026, the SCJN validated collective authorizations: a single permit can now cover several specifically named individuals. COFEPRIS reiterated in July 2026 that this decision opened neither sales nor a general decriminalization.

Borders, planes, vapes: the travel traps

Three mistakes to never make:

• Crossing a border with cannabis. In either direction. Heading north, US federal law applies. Heading south, importing cannabis into Mexico is a serious federal offense, punishable by several years in prison. US medical cards have no value there.
• Taking it on a plane. Domestic or international flight, no legal framework allows a tourist to transport cannabis.
• Bringing a vape. Since January 2025, the Constitution prohibits the production, distribution, and sale of electronic cigarettes and vapes. A reform from December 2025 punishes their production, transport, and sale with 1 to 8 years in prison. Personal use is not in principle sanctioned, but customs seizures are frequent.

And once back in France, Mexican tolerance no longer exists: the fixed fine regime applies. To compare Mexico with its two neighbors, we have gathered everything in our North America guide.

Key Takeaways

Mexico has decriminalized through its courts what its Parliament never dared to regulate. The result: no prosecution under 5g in principle, authorization possible to grow, but zero legal points of sale in the entire territory.

For a traveler, the right attitude is the simplest: buy nothing, transport nothing, and do not confuse a storefront in Tulum with a California dispensary.
