Cannabis Use Disorder
When cannabis becomes difficult to control or keeps causing problems, treatment may help you change the pattern.
What is cannabis use disorder?
Cannabis use disorder is a pattern of cannabis use that causes significant problems or distress. A person may want to cut back but struggle to do so, continue using despite consequences, or find that more time and attention revolve around cannabis.
The diagnosis is based on the pattern and its impact, not simply whether someone uses cannabis, how it is obtained, or whether it is legal. Severity varies.
What signs are worth noticing?
Signs may include:
- Using more or for longer than intended.
- Repeated efforts to reduce use that do not last.
- Cravings or substantial time spent using or recovering.
- Problems with responsibilities, relationships, or activities.
- Continuing despite physical or psychological problems.
- Tolerance or withdrawal symptoms.
Withdrawal may involve irritability, anxiety, sleep difficulty, reduced appetite, and restlessness. These symptoms may make an attempt to stop harder even when the reasons for change are clear.
How may cannabis affect health?
Attention, driving, and mental health: Cannabis may impair attention, memory, coordination, and driving. Higher-potency THC exposure and frequent use may increase risks. Some people experience panic, paranoia, or psychotic symptoms; vulnerability and the pattern of use matter.
Repeated vomiting: Repeated severe vomiting may be associated with cannabis use and needs medical assessment. Discuss any symptom you are trying to treat with cannabis, because that concern may need its own treatment plan.
How is it assessed?
The pattern of use: Your provider asks about frequency, amount, THC strength when known, formulations, reasons for use, attempts to change, and consequences. They also review sleep, mood, anxiety, other substances, and physical health.
Goals and test limitations: The conversation should identify what you want to improve. A urine result alone cannot describe the severity of the disorder or establish whether someone is currently impaired.
What treatments help?
Behavioral treatment: Behavioral treatments include cognitive behavioral therapy, motivational approaches, and contingency management, which uses structured rewards for treatment goals. Care may address cravings, triggers, routines, and the symptoms that cannabis has been used to manage.
Medication and other support: There is currently no FDA-approved medication specifically for cannabis use disorder. A provider may treat associated symptoms or another condition while helping you change cannabis use. A more intensive program may be useful when outpatient support is not enough.
Planning a change
Planning for cravings and withdrawal: Discuss whether your goal is stopping or reducing use and what support will make that plan realistic. Prepare for sleep or mood changes, reduce easy access to usual cues, and identify someone you can contact when cravings become difficult.
Do not drive while impaired or combine cannabis with other substances that increase sedation. Seek urgent assessment for severe confusion, hallucinations, persistent vomiting, dehydration, or chest pain. Ask your provider how progress will be measured and what to do if the first plan is not working.
