Cannabis Laws in Mexico
Personal use decriminalized via court rulings; medical legal since 2017; no recreational market.
This article is general information, not legal advice. Laws change; check current rules with official sources or a lawyer.
Mexico's cannabis situation is genuinely unusual: the courts have repeatedly ruled absolute prohibition unconstitutional, but Congress hasn't passed a recreational law to replace it. This creates a working legal gray zone where personal use is tolerated and medical is regulated, but there's no retail system. If you're not a Mexican resident with a permit, buying or growing is illegal. Foreign visitors should expect the same risks as anywhere prohibition exists.
Overview: The legal limbo
Cannabis in Mexico exists in a constitutional stalemate. The Supreme Court of Justice of the Nation (SCJN) has ruled multiple times that absolute prohibition of adult personal use violates the constitutional right to free development of personality. However, Congress has repeatedly failed to enact a comprehensive recreational regulatory law, despite court-imposed deadlines.
In practice:
- Adults can legally possess and consume cannabis for personal use, either by obtaining an individual permit from COFEPRIS (the federal health regulator) through a constitutional lawsuit (amparo), or by invoking the SCJN's general declaration of unconstitutionality issued in June 2021.
- Possession of up to 5 grams is not subject to criminal prosecution under Article 479 of the General Health Law [2] Strong evidence.
- Medical cannabis is legal and has been regulated since January 2021 [3] Strong evidence.
- There is no legal recreational retail market. Buying or selling cannabis commercially remains illegal.

Legal history and the court rulings
Cannabis prohibition in Mexico has deep roots in early-20th-century criminalization and was hardened during the U.S.-led war on drugs. The modern reform cycle began in 2009, when Congress passed the narcomenudeo reform, which decriminalized possession of small quantities (5 grams for cannabis) for personal use [2] Strong evidence.
The watershed moment came in November 2015, when the SCJN issued its first landmark ruling in Amparo en Revisión 237/2014 (the "SMART" case), holding that prohibiting an adult from growing and consuming cannabis for personal recreational use violates Article 1 of the Constitution, which guarantees the right to free development of personality Strong evidence.
Under the Mexican legal system, binding jurisprudence is established when five consistent court decisions reach the same conclusion. By 2018, the SCJN had issued the fifth such ruling, establishing binding precedent and ordering COFEPRIS to grant personal-use cultivation permits to plaintiffs who filed constitutional lawsuits Strong evidence.
In parallel, June 2017 saw Congress legalize medical cannabis by amending the General Health Law and the Federal Penal Code, removing cannabis derivatives with up to 1% THC from Schedule I Strong evidence. Implementing regulations were published by the health ministry on 12 January 2021 [3] Strong evidence.
On 28 June 2021, after Congress had missed multiple deadlines to pass a recreational framework, the SCJN issued a Declaratoria General de Inconstitucionalidad (General Declaration of Unconstitutionality) striking down the specific articles of the General Health Law that prohibit personal recreational use Strong evidence. As of this article's last-verified date (October 2026), Congress has not enacted a comprehensive recreational law.
Personal possession and consumption
The 5-gram threshold. Article 479 of the General Health Law establishes 5 grams of cannabis as the maximum amount considered for strictly personal and immediate consumption [2] Strong evidence. Below this amount, the Ministerio Público (prosecutor's office) is instructed not to pursue criminal charges, though authorities may still detain, identify, and refer individuals to treatment services.
Above 5 grams. Possession exceeding the threshold can be charged as simple possession or — at significantly higher quantities — possession with intent to supply, which carries prison sentences. There is no fixed upper limit before charges escalate; prosecutors have discretion based on circumstances including quantity, packaging, scales, and other evidence of distribution intent.
Public consumption. Cannabis smoking in public is regulated by the Ley General para el Control del Tabaco (General Law for the Control of Tobacco) and local ordinances. Mexico City and several states treat cannabis smoke under the same smoke-free regulations as tobacco Weak / limited. Specific penalties vary by municipality.
Driving under the influence. Driving while impaired by cannabis is illegal nationwide and is generally enforced under state traffic codes. Mexico does not have a standardized roadside THC testing protocol comparable to some other countries.
Personal cultivation: permits and the COFEPRIS pathway
Because Congress has not legislated a comprehensive personal-use framework, the legal pathway for personal cultivation runs through individual constitutional litigation. A person files an amparo (constitutional protection lawsuit) against COFEPRIS, arguing that the prohibition violates their constitutional rights. Federal courts have consistently granted these lawsuits, citing the SCJN's jurisprudence, and COFEPRIS has been ordered to issue permits allowing the holder to grow, possess, transport, and consume cannabis for strictly personal use — without selling, gifting to adults, or supplying minors Strong evidence.
Permits are individual, non-transferable, and explicitly exclude commercial activity. The number of plants and grams allowed has varied from case to case; early permits typically authorized small personal grows Weak / limited.
Following the SCJN's June 2021 general declaration of unconstitutionality, COFEPRIS is technically obligated to grant such permits without requiring each applicant to file a separate lawsuit. However, reporting and advocacy organizations indicate the agency has been slow and inconsistent in processing applications, and many Mexicans still resort to litigation to obtain permits Weak / limited. The reasons for delays are not well documented in public sources.
Medical cannabis
Medical cannabis was legalized at the federal level in June 2017 through amendments to the General Health Law and the Federal Penal Code Strong evidence. These changes removed cannabis derivatives up to 1% THC from the most-restricted schedule and opened the legal door for medical, scientific, and industrial applications.
Implementing regulations — the Reglamento de la Ley General de Salud en Materia de Control Sanitario para la Producción, Investigación y Uso Medicinal de la Cannabis y sus Derivados Farmacológicos — were published on 12 January 2021 in the Diario Oficial de la Federación [3] Strong evidence. The framework establishes processes for cultivation permits, manufacturing, importation, and the registration of cannabis-based medicines, all under COFEPRIS oversight.
The practical market remains small. Most commercially available legal cannabis products in Mexico are CBD-dominant; few THC-containing pharmaceutical preparations have completed COFEPRIS registration. The regulatory process for new medicinal cannabis products can be lengthy, and licensed domestic production capacity remains limited Weak / limited.
Hemp and CBD products
Mexico does not have a separate hemp statute equivalent to the U.S. 2018 Farm Bill. Instead, CBD and other cannabis products are regulated under the medical cannabis framework when they make therapeutic or health claims, and as dietary supplements, cosmetics, or personal-care products in other cases.
CFOPRIS maintains authority over cannabis-derived products that make health claims. A small number of CBD products have been authorized for sale through COFEPRIS registration, though the exact number and product list are not regularly published in a centralized, accessible database Weak / limited.
Imported CBD products technically require COFEPRIS authorization. However, enforcement against unregistered imported CBD products—particularly those marketed as dietary supplements or cosmetics rather than medicines—has been inconsistent. Many CBD products are available for purchase online and in retail shops with varying degrees of regulatory compliance.
Travel and foreign visitors
Importing cannabis. Bringing cannabis or cannabis products into Mexico is illegal, regardless of medical authorization or legal status in another country. Mexican customs does not recognize foreign medical cannabis cards or prescriptions.
Foreign residents and tourists. Visitors are subject to the same 5-gram possession threshold under Article 479 of the General Health Law [2]. The COFEPRIS personal-use permit pathway has been used primarily by Mexican nationals and residents; it is not a practical option for foreign visitors. A foreign tourist would need to file a constitutional lawsuit and establish residency to obtain a permit.
"Cannabis clubs" and dispensaries. There is no legal recreational dispensary or "club" system in Mexico. Anything marketed or sold as a cannabis dispensary, club, or delivery service to foreign visitors or locals is operating in violation of federal law, regardless of how openly it advertises or claims to operate under a gray-zone interpretation Anecdote. Buyers are exposed to the same legal risks as illicit possession.
Current legislative status and outlook
A comprehensive Ley Federal para la Regulación del Cannabis (Federal Law for the Regulation of Cannabis) passed the Chamber of Deputies in March 2021 but stalled in the Senate. Attempts to reconcile the versions between chambers did not result in final passage as of this article's last-verified date (October 2026) Weak / limited.
The political appetite for finalizing recreational legalization has fluctuated across legislative sessions, and as of October 2026, no new comprehensive framework has been enacted. Until Congress acts, the legal situation is unlikely to change substantially: the SCJN will continue protecting personal use through the courts, COFEPRIS will continue issuing permits (albeit slowly), and there will remain no legal recreational retail market.
