Social class, race, and gender shaped whether marijuana promoted or harmed well-being among Brazilians

A survey of 2,637 Brazilian adults found that the well-being effects of marijuana use and its prohibition varied sharply by race, gender, income, and education, with Indigenous peoples and youth most affected by criminalization.

What This Study Found

Among 2,637 respondents, using marijuana for fun was most common among self-identified males, trans/non-binary people, college graduates, and higher-income individuals. Indigenous peoples and youth were most likely to report trouble with police due to marijuana. Higher education and longer use predicted more harm reduction strategies. Women and higher-income individuals were less likely to report daily use. Living with family and less frequent use protected against negative effects of intoxication.

Key Numbers

2,637 respondents; Indigenous peoples and youth most affected by policing; higher education associated with more harm reduction; women and higher income less likely to use daily; living with family protective

How They Did This

Cross-sectional study using anonymous online questionnaire in Brazil with 2,637 respondents. Logistic regression analyzed predictors of well-being including use benefits, prohibition risks, and harm reduction strategies across socioeconomic characteristics.

Why This Research Matters

In a country where marijuana remains criminalized, the harms of prohibition fall disproportionately on marginalized populations, adding a social justice dimension to cannabis policy debates.

The Bigger Picture

Cannabis prohibition does not affect everyone equally. When enforcement disproportionately harms Indigenous, young, and lower-income populations, the policy itself becomes a determinant of health inequity.

What This Study Doesn't Tell Us

Online convenience sample likely skews toward educated, connected populations. Self-reported well-being is subjective. Cross-sectional design cannot establish causation. Brazilian context may not generalize.

Questions This Raises

  • ?Would decriminalization in Brazil reduce the racial and socioeconomic disparities in prohibition harms?
  • ?Do harm reduction strategies mediate the relationship between marijuana use and well-being?
