Six Years of Missed Deadlines
The SCJN first ordered Congress to legislate cannabis in 2018. Successive deadline extensions — December 2019, April 2020, December 2020, April 2021 — produced no enacted law. As of April 2026, no comprehensive federal recreational cannabis statute has been passed by both chambers and signed. Mexico is among the most chronically delinquent legislatures in modern reform history on this question.
The November 2020 Senate Bill
The closest the country came was the Ley Federal para la Regulación del Cannabis, approved by the Senate on November 19, 2020, by 82 votes in favor, 18 against, and 7 abstentions. The bill was shepherded through the Senate Justice Committee by then-Senator Olga Sánchez Cordero, with the support of Morena Senate leader Ricardo Monreal Ávila.
The bill envisioned:
- A new regulator: the Instituto Mexicano para la Regulación y Control del Cannabis.
- Five license categories — cultivation, transformation, sale, export/import, research.
- Personal possession of up to 28 grams, with administrative penalty between 28 g and 200 g.
- Home cultivation of up to 6 plants per person, 8 per household.
- Adult-use establishments separate from medical pharmacies.
- A 12% special tax (IEPS).
- Social-equity priorities for indigenous and traditionally cannabis-dependent farming communities.
The Chamber of Deputies received the bill, marked it for the next periodo, demanded amendments, and never delivered a final-passage vote. The bill technically remains live in legislative limbo, but successive sessions have avoided returning to it.
The AMLO Years (2018–2024) — Ambivalence
President Andrés Manuel López Obrador (AMLO) held office from December 1, 2018 to September 30, 2024. He was personally ambivalent on cannabis legalization: he repeatedly said he would respect what Congress decided, supported the 2020 Senate bill in principle, but invested almost no political capital in passage. Several reasons converged:
- His core security framing — abrazos no balazos — emphasized social programs over drug-enforcement reform; he was wary of being seen as soft on narcotics.
- The Morena bench in the Chamber of Deputies split between progressive urban legislators (CDMX, Jalisco) and rural representatives from cannabis-producing states who feared cartel-displacement effects.
- The Catholic and evangelical electorate, which Morena increasingly courted, mobilized against legalization through groups like the Frente Nacional por la Familia.
- AMLO's personal preference for sober/non-consumption messaging.
His Secretario de Gobernación for most of the term, Adán Augusto López Hernández, also offered no decisive push, and is widely credited (or blamed) for letting the bill expire.
The Sheinbaum Administration (October 2024–present)
President Claudia Sheinbaum Pardo took office October 1, 2024. She is a climate scientist, former Jefa de Gobierno of CDMX, and a more technocratic figure than AMLO. As CDMX head, she presided over a relatively tolerant municipal posture, including the Plantón 420 activism encampment in front of the Senate.
As of April 2026, the Sheinbaum administration has not advanced a federal recreational cannabis bill to passage. Her stated priorities have been security reform, judicial reform (the controversial 2024–2025 elected-judges overhaul), social programs, and the U.S. relationship under a renewed Trump administration. Cannabis surfaces in occasional press-conference questions but is not on the publicly stated 2025–2026 legislative agenda.
Party-by-Party Positions
- Morena — officially supports regulation per its 2018 platform; internally split between urban progressives (favorable) and rural/evangelical-aligned legislators (skeptical or opposed). Sheinbaum-aligned Morena members are mildly favorable.
- PAN (Partido Acción Nacional) — generally opposed on conservative/Catholic grounds; some libertarian-leaning federal deputies dissent.
- PRI (Partido Revolucionario Institucional) — historically opposed; party voted against the 2020 Senate bill but is internally divided.
- PRD (Partido de la Revolución Democrática) — historically the most pro-legalization party. Marginalized after 2024 elections.
- MC (Movimiento Ciudadano) — broadly pro-regulation; Jalisco-based MC legislators are among the most articulate reform voices.
- PVEM (Partido Verde Ecologista de México) — formally supportive of regulation, especially of medical and hemp.
- PT (Partido del Trabajo) — generally supportive when allied with Morena.
Public Health vs. Justice — Two Competing Frames
Two competing frames have shaped the debate:
- Salud pública (public health) — favored by the Secretaría de Salud, COFEPRIS, and most reformers. Cannabis is treated as a substance to regulate like alcohol/tobacco, with emphasis on age limits, advertising restrictions, and harm reduction.
- Justicia / seguridad (justice/security) — favored by the Secretaría de Gobernación and security cabinet. Emphasizes reducing violence, displacing illicit markets, and law enforcement.
The 2020 Senate bill leaned health; AMLO's security cabinet pulled toward the justice frame; the lack of consensus between these poles has been a persistent obstacle.
What a Future Mexican Recreational Market Would Likely Include
Based on the 2020 bill and subsequent committee drafts circulated through 2022 in the Chamber of Deputies' Salud and Justicia committees, a future Mexican recreational regime would likely include:
- A dedicated federal regulator
- Vertically segmented licenses with social-equity quotas
- A 5–6 plant home-grow allowance
- Possession limits in the 25–30 g range
- Adult-use specialty stores, not pharmacies
- An IEPS in the 12–15% range
- Advertising restrictions modeled on tobacco
- THC-content caps debated but unsettled
Reform Calendar & Outlook
The Mexican Congress operates in two ordinary sessions per year (September–December, February–April). The 2025–2026 legislative calendar has so far seen no comprehensive cannabis bill on the priority docket. Standalone medical-cannabis access bills, hemp-industrial bills, and amparo-process simplification bills have been introduced in committee and not voted out.
Reform advocates including MUCD and CuPIHD continue to lobby. Senators including Lilly Téllez (PAN, opposed) and members of Movimiento Ciudadano (mixed) have publicly debated but not voted. The most plausible scenarios for movement are post-2027 midterms or in the wake of significant U.S. federal cannabis policy change.
Spillover from U.S. Legalization
U.S. state legalization has reshaped Mexican public opinion in two ways: by demonstrating that regulated markets are operationally feasible without collapse of public order; and by creating the visible "tourist sees California legal but Mexican store closed" anomaly that elite reform discourse has used effectively. Federal U.S. legalization, if it occurred, would significantly raise the political pressure on Mexico to act; under the second Trump administration this pressure has not materialized.
