Can Weed Increase Risk Of Type 2 Diabetes?
Analysis of health records from over four million adults reveals that cannabis users face nearly four times the risk of diabetes compared to non-users, urging enhanced metabolic monitoring and counseling.
- At a conference held in Vienna from September 15-19, 2025, researchers revealed an analysis linking cannabis consumption to nearly a fourfold increase in the likelihood of developing diabetes.
- The researchers utilized data from the TriNetX Research Network, which includes patient records from 54 medical institutions across the USA and Europe, analyzing information on over 4 million adults matched by age, gender, and health conditions, with records spanning 2010 to 2018.
- Researchers found that 2.2% of cannabis users developed new diabetes cases compared to 0.6% in matched healthy controls, indicating nearly four times the risk among cannabis users.
- Dr. Ibrahim Kamel emphasized that recent findings from robust real-world data underscore the necessity of incorporating education about diabetes risk into programs and counseling for individuals undergoing treatment for substance use disorders.
- The findings prompt calls for routine metabolic monitoring of cannabis users and further research on long-term effects, especially regarding diabetes risk across different cannabis forms.
