Cannabis use disorder (CUD) is caused by long-term, heavy cannabis use. This can lead to physical and psychological dependence, as well as problems with cognitive, behavioural and social functioning.
Diagnosis of CUD is based on the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). These include a pattern of cannabis use leading to clinically significant impairment or distress, as well as evidence of tolerance and withdrawal symptoms.
It is important to consider other potential causes of the symptoms, such as other substance use disorders, mood disorders, anxiety disorders, and psychotic disorders.
Treatment for CUD typically includes cognitive behavioural therapy, psychotherapy, and medications. There are also a number of support groups available to help individuals manage their symptoms.
The prognosis for CUD depends on the severity of the disorder, the individual’s motivation to change, and their willingness to engage in treatment. Generally, individuals who are committed to abstinence and treatment have the best outcome.
