Marijuana is the most widely used illicit substance in both the U.S. and Indiana and its use has been increasing in recent years. Prevalence estimates for current (past month) use of marijuana are available from the National Survey on Drug Use and Health for the Indiana and U.S. population 12 years of age or older.

Estimates of current (past month) marijuana use by high school students in grades 9 through 12 are available for the Center for Disease Control and Prevention’s (CDC) Youth Risk Behavior Surveillance System (YRBSS)
Information on persons entering substance abuse treatment related to marijuana use is available from the Treatment Episode Data System (TEDS). The TEDS provides the number of persons entering substance use treatment, the drugs they are using at the time of admission, the primary drug for which they are seeking treatment, as well as basic demographic information. TEDS data are available for both Indiana and the U.S.; however, TEDS data for Indiana do not reflect all persons in substance abuse treatment but only those in treatment at facilities that receive funds from the Indiana Division of Mental Health and Addictions. TEDS data related to marijuana use can be viewed by age, race, and gender. The percent of treatment admissions related to marijuana can be viewed across the state for the past 10 years and trend data are available for each of Indiana’s 92 counties.
