Interactive Adult Marijuana Data Now Available

Data on adult marijuana use in Colorado is now available on a user-friendly, interactive website at

This data is from the Behavioral Risk Factor Surveillance System (BRFSS) survey. BRFSS is a telephone survey of adults ages 18 years and older, sponsored by the U.S. Centers for Disease Control and Prevention (CDC). Beginning in 2014, Colorado added questions about marijuana use to the state-level BRFSS. These questions cover:

  • Marijuana use in the past 30 days (number of days and times per day)
  • Method of marijuana use (smoking, vaping, edible, etc.)
  • Driving after using marijuana
  • Perceived health risk of marijuana use  

Results for all Coloradoans and for different age groups, sex, race and sexual orientation are available, including some regional and county level data.

The Colorado Department of Public Health and Environment will be transitioning their other marijuana related data to this same user-friendly, interactive format as the newest data becomes available.
