Legislative History
Mexico's Supreme Court decriminalized recreational adult use in 2021, allowing possession of up to 28 grams and personal cultivation of up to six plants. Medical cannabis has been regulated since 2017, with prescription access for patients. While progress toward a fully regulated commercial market continues, licensed retail sales remain in development as of December 2025.
Law Enforcement
Police could be quick to bust you. There were stories of 100–200 peso bribes, jail for a while or being beaten and left tied up if you antagonized an officer. Those were warnings people traded, not reliable predictions.
