Data
Baseline: 1.6 percent of persons aged 12 years and over had a marijuana use disorder (defined as meeting DSM-IV criteria) in the past 12 months in 2018
Target: 1.3 percent
Methodology
NSDUH respondents who used marijuana on 6 or more days in the past 12 months were categorized as having a marijuana use disorder if they met the DSM-IV criteria for either dependence or abuse for marijuana. Illicit drug use disorder is defined as meeting DSM-IV criteria for either dependence or abuse for one or more of the following illicit drugs: marijuana, cocaine, heroin, hallucinogens, inhalants, methamphetamine, or prescription psychotherapeutic drugs that were misused (i.e., pain relievers, tranquilizers, stimulants, and sedatives).
