Marijuana addiction is classified under the DSM-5 as a substance use disorder with varying severity levels based on the number of criteria met within 12 months. These criteria include loss of control over use, social impairments, tolerance, withdrawal symptoms, and continued use despite negative consequences. A diagnosis requires at least two of these criteria to be present. Addictive disorders can produce a range of symptoms that were previously (DSM-IV) described using the terminology “psychological dependence” and physical dependence.

The impact may be broad, including impaired control, social impairment, risky use and pharmacological criteria (including tolerance and withdrawal).
