Health Data

The Marijuana Health Monitoring Program  at the Colorado Department of Public Health and Environment (CDPHE) is tasked with collecting data to monitor marijuana related health effects and marijuana use/consumption trends per 25-1.5-110 C.R.S. The program  has worked with our partners to explore data sources that contain information relevant to marijuana use/consumption and health effects surveillance. Marijuana use/consumption in Colorado is determined using data from population-based surveys and surveillance of health effects is determined using data from health incident databases. Below is a brief description of each data source we use by topic area.  Scroll down and click on each data source to explore the data in detail.
