Why Some University Students Might Use Marijuana More Than Others

Minas Gerais, BrazilThursday, July 2, 2026

A groundbreaking study has uncovered surprising insights into marijuana use among health science students in eastern Brazil. Out of more than 500 students surveyed, nearly one in five admitted to trying marijuana at some point. But this wasn’t just a simple count—researchers dug deep to uncover the hidden influences behind the numbers.

Who Was More Likely to Use Marijuana?

The findings painted a complex picture:

  • Race & Ethnicity: Students who did not identify as white were less likely to have tried marijuana, challenging assumptions about drug use patterns.
  • Living Arrangements: Those in dorms, shared apartments, or living alone were over twice as likely to use marijuana compared to students living with family.
  • Family Ties: Students with poor or no contact with their fathers were nearly two and a half times more likely to try marijuana.
  • Religious Beliefs: Surprisingly, students without a religious affiliation were six times more likely to experiment with marijuana than those who identified with a faith.

How the Study Was Conducted

Researchers used detailed surveys to gather data. Students first answered basic questions about age, gender, and race, followed by deeper inquiries into their habits—including tobacco, alcohol, and other drug use. Using statistical analysis, the team identified which factors correlated most strongly with marijuana use.

Why These Findings Matter

This study isn’t just about numbers—it highlights real-world disparities in risk factors. Students who feel disconnected from family or lack strong community ties through religion may face higher exposure to substance use. While the study doesn’t explain why these factors influence behavior, it clearly shows they do.

The research suggests that education and support systems may need to focus on these vulnerable groups, ensuring they have the resources to make informed choices.

Could this be a call for targeted interventions in student health and wellness programs?
