Marijuana addiction appears to be very similar to other substance use disorders. People with marijuana use disorders, especially adolescents, often also suffer from other psychiatric disorders (comorbidity). They may also abuse or be addicted to other substances, such as cocaine or alcohol. Available studies indicate that effectively treating the mental health disorder with standard treatments involving medications and behavioral therapies may help reduce marijuana use, particularly among heavy users and those with more chronic mental disorders. The following behavioral treatments have shown promise:
- Cognitive-behavioral therapy: A form of psychotherapy that teaches people strategies to identify and correct problematic behaviors in order to enhance self-control, stop drug use, and address a range of other problems that often co-occur with them.
- Contingency management: A therapeutic management approach based on frequent monitoring of the target behavior and the provision (or removal) of tangible, positive rewards when the target behavior occurs (or does not).
- Motivational enhancement therapy: A systematic form of intervention designed to produce rapid, internally motivated change; the therapy does not attempt to treat the person, but rather mobilize their own internal resources for change and engagement in treatment.
