  • OR for having DM among marijuana users compared to non-users and 95% CI.

  • Social variables: race/ethnicity, physical activity, alcohol use, interaction of alcohol and marijuana use and body mass index.

  • Laboratory variables: total cholesterol and triglyceride.

  • Inflammatory marker: C reactive protein.

  • Comorbidity: hypertension.

  • * p<0.0001 compared to non-marijuana users.
