Recreational cannabis use is increasing in Mexico, where legalization is a possibility. The current area-level socioeconomic context of cannabis use has not been studied in the country, limiting our understanding and public health response. We aimed to analyze the association between the municipal socioeconomic environment and recreational cannabis use in Mexico. We used data from the National Survey of Drug, Alcohol and Tobacco Consumption 2016-17, the National Health and Nutrition Survey 2023, the 2015 intercensal survey and the 2020 census to study the association of municipal income and municipal education with past-year recreational cannabis use. We fitted Poisson models with robust variance to obtain prevalence ratios and assessed for effect modification by individual-level sex and age, and household-level education. For every unit increase in municipal education, we observed a 1.5 % increase in the prevalence of recreational cannabis use in 2016-17, and a 2.9 % increase in 2023. For each unit increase in municipal income, we observed a 1.5 % increase in the prevalence of recreational cannabis use in 2016-17, and a 1.8 % increase in 2023. We found no effect modification except for a single age group (20- to 29-year-olds vs to 12- to 19-year-olds). Recreational cannabis use in Mexico is currently higher in more socioeconomically advantaged municipalities. Recreational cannabis use through socioeconomic areas should be monitored closely. Further research of the modifiable causes of this association could help inform current and future public health policies.
