In March 2016, Deborah Hasin, Ph.D. and others published the first national study of cannabis use disorder using DSM-5 diagnostic criteria in The American Journal of Psychiatry. With a sample size of over 36,000, this important study evaluates cannabis use and prevalence, correlates with other mental health problems and rates of participation in treatment.
Additionally, cannabis use disorder is associated with other substance use disorders, affective disorders, anxiety, and personality disorders. Dr. Hasin reported that three out of 10 marijuana users experienced marijuana abuse or dependence in 2012-13. DSM-5 no longer uses the terms substance abuse and substance dependence, rather it refers to substance use disorders, which are defined as mild, moderate, or severe to indicate the level of severity, which is determined by the number of diagnostic criteria met by an individual. Substance use disorders occur when the recurrent use of alcohol and/or drugs causes clinically and functionally significant impairment, such as health problems, disability, and failure to meet major responsibilities at work, school, or home. According to the DSM-5, a diagnosis of substance use disorder is based on evidence of impaired control, social impairment, risky use, and pharmacological criteria.
The researchers found that only about 7 percent of people with past-year marijuana use disorder receive any marijuana-specific treatment, and only about 14 percent of people with lifetime marijuana use disorder receive treatment.
