Is Marijuana Legal in Mexico?

Last updated: July 2026. The legal information in this article is of a general informative nature and does not substitute professional legal advice. The legal framework for cannabis in Mexico is still in transition and may change. Always verify updated information before your trip.

Personal use is decriminalized, not legalized, and there is no legal commercial market. It's a distinction that changes everything: decriminalized means you won't be prosecuted criminally for a small amount for personal consumption. Legalized would mean there are authorized stores where you can buy. The latter doesn't exist in Mexico, no matter what certain websites say.

A second distinction, equally important: the CBD stores you'll see openly in tourist areas or cities (Tulum, CDMX, Playa del Carmen) are not the same as marijuana dispensaries. CBD with low THC content is regulated differently and can legally be sold in physical stores; it's a completely different product from psychoactive cannabis. Don't confuse them.

What the law says exactly

In 2021, Mexico's Supreme Court of Justice declared the total prohibition of personal cannabis use for adults unconstitutional, based on the right to free development of personality. This opened the door for adults to possess, consume, and even grow cannabis for strictly personal use, under certain conditions.

But Congress never approved the law that would regulate a commercial market and continues not to approve it through 2026. This leaves the country in what several legal analyses literally describe as a "constitutional gray zone": personal use has judicial protection, but buying, selling, or importing cannabis remains a federal crime.

The amount is what truly confuses

The official "maximum dose" table from the General Health Law establishes 5 grams as the limit that is not criminally prosecuted for possession for immediate consumption. You'll find sources mentioning 28 grams; that figure corresponds to a different context—personal cultivation permits filed with COFEPRIS, not the amount you can freely carry on the street. For practical purposes as a tourist, the relevant and safety figure is 5 grams, and even then, law enforcement varies by officer and state; that amount is not an automatic guarantee.

What is NOT legal

• Buying or selling — remains a federal crime, without exception, regardless of quantity
• No legal dispensaries for tourists exist in any Mexican state; anyone telling you otherwise is misinformed or setting you up for a scam
• Importing cannabis to Mexico — even in minimal amounts, even if you bought it legally in your country of origin, is a serious federal crime, with strict review at airports and borders
• Consumption in public spaces — can result in municipal fines, although possession itself may not be prosecuted
• Medical cannabis for tourists — technically a regulated framework exists, but requires a prescription from an authorized Mexican doctor and procedures with COFEPRIS that are completely impractical for a short visit

CBD is a completely different topic, don't confuse it with marijuana

It's very likely you'll see CBD stores in tourist areas (Tulum, Playa del Carmen, CDMX, Puerto Vallarta) with display windows full of oils, creams, gummies, and even CBD flower. A store selling CBD products doesn't mean it's selling marijuana, and these are two distinct legal situations worth not mixing up:

• CBD (cannabidiol) with less than 1% THC is regulated as industrial hemp under Mexican law, not as psychoactive cannabis, which is why these stores can operate openly, with street signage and without the legal ambiguity surrounding THC cannabis
• These products don't give you the psychoactive effect — they won't give you the "high" or trip of traditional marijuana; they're designed and marketed with messaging related to anxiety, pain, inflammation, sleep, not recreational use
• Buying at these stores is legal and safe; you're not in any gray zone doing so, unlike buying marijuana
• Even so, verify the packaging and % THC before buying since some "CBD products" in tourist areas may have more THC than declared, and that does put you in the legal ambiguity we discussed above. Buy at established stores with clear labeling, not at improvised stands
• To cross the border back to your country with CBD products — always check your country of origin's laws, not Mexico's; many countries have their own allowed THC limits for CBD products when importing, and that's your responsibility to verify beforehand, not something the Mexican store will warn you about

The real risk

Law enforcement depends on the officer's discretion in the moment, and this has generated documented cases of police using legal ambiguity as a pretext to ask for bribes: "you have marijuana, this could be a problem, but we can work it out here." If you've already read our guide on what to do if a police officer asks you for money, that same protocol applies here: don't offer money, ask that everything be documented officially.

The official stance of foreign governments

The embassies of several countries, including the United States, maintain active warnings indicating that possession and use of drugs, including medicinal marijuana from other countries, is illegal in Mexico and can result in detention. This may sound contradictory to Mexican decriminalization, but it reflects the reality of the "gray zone": your embassy cannot guarantee you legal protection if you run into trouble, even though Mexican law may technically be on your side for small amounts.

Summary

If you decide on your own to consume cannabis in Mexico (which is your decision, not advice on our part), the real information is: amounts up to 5 grams for personal consumption have legal backing according to the Supreme Court, but buying remains illegal, there are no real dispensaries for tourists, and practical enforcement on the street depends on the officer you encounter. The safest option remains simply not doing it during your trip to Mexico, but if you decide otherwise, do it with this precise information, not with what people and websites that want to incite illegal sales of these products promise.
