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
The talk in Hermosillo was that a cop would take $20 to go away, or $10 if you got lucky. I wouldn’t bet on that.
Where to Buy Marijuana
Santa Fe was one of the easier places to hear about weed. Hermosillo felt small enough that a dealer would sometimes deliver for a purchase of 50 grams or more.
I stayed wary around people I didn’t know. Getting robbed was a real concern in some neighbourhoods.
Marijuana Prices
- One gram: approximately one peso.
- 100 grams: around 80–90 pesos.
- A kilogram: roughly 500–800 pesos, and harder to locate.
A kilo was much harder to find than the smaller amounts.
More Information
Most of the time someone knew somebody and had a phone number. Around holidays it could be harder because everybody seemed to be buying at once.
