Cannabis Use Disorder

Overview

Cannabis use disorder is a medical condition in which a person's use of cannabis (marijuana) becomes problematic, causing distress or difficulties in daily life and making it hard to stop or cut back. While many people use cannabis without developing a disorder, a meaningful number do, and the risk is higher with frequent use, higher-potency products, and starting at a young age.

Cannabis use disorder exists on a spectrum from mild to severe. Some people develop tolerance, needing more to get the same effect, and experience withdrawal symptoms when they stop. Like other substance use disorders, it is treatable, and many people recover with the right support.

Symptoms

Cannabis use disorder is diagnosed by a pattern of use that leads to significant problems. Signs include:

• Using more cannabis, or for longer, than intended
• Wanting to cut down but being unable to
• Spending a lot of time getting, using, or recovering from cannabis
• Strong cravings to use
• Use interfering with work, school, or home responsibilities
• Continuing to use despite relationship or health problems caused by it
• Giving up important activities in favor of using
• Needing more to get the same effect (tolerance)
• Withdrawal symptoms such as irritability, sleep problems, decreased appetite, restlessness, or low mood when stopping

The more of these features a person has, the more severe the disorder.

Causes

Cannabis use disorder develops through a mix of biological, psychological, and social factors.

• Brain effects: Cannabis acts on the brain's reward system, and repeated use can lead to tolerance and dependence.
• Genetics: A family history of substance use disorders increases risk.
• Early and frequent use: Starting young and using often or with high-potency products raises the chance of developing a disorder.
• Mental health: Conditions such as anxiety, depression, or trauma can contribute.
• Environment: Easy access, peer use, and stress play a role.

Risk Factors

• Starting cannabis use in adolescence
• Frequent or daily use
• Use of high-potency cannabis products
• A family or personal history of substance use disorders
• Co-occurring mental health conditions
• High levels of stress or limited support

Diagnosis

A doctor or mental health professional diagnoses cannabis use disorder through a clinical assessment, not a single test. Evaluation may include:

• A detailed conversation about the pattern of use, its effects on life, and any attempts to cut back.
• Reviewing diagnostic criteria, counting how many features are present over the past year to gauge severity.
• Screening for other conditions, such as anxiety, depression, or other substance use.
• A general health check to identify any related physical effects.

Treatment

Treatment focuses on counseling and behavioral approaches, as there is no specific medication approved to treat cannabis use disorder.

• Behavioral therapy: Cognitive behavioral therapy helps identify triggers and build coping skills, while motivational approaches strengthen the desire to change.
• Counseling and support: Individual or group counseling and peer support programs.
• Managing withdrawal: Symptoms like irritability, sleep trouble, and appetite changes are usually temporary; supportive care helps.
• Treating co-occurring conditions: Addressing anxiety, depression, or other substance use improves outcomes.

Recovery is a process, and setbacks can happen. Ongoing support helps people reduce or stop use and rebuild daily life.

Prevention

• Delay or avoid cannabis use, especially during adolescence when the brain is developing
• Be cautious with frequent use and high-potency products
• Seek healthy ways to manage stress, anxiety, and sleep
• Get help early for mental health concerns
• Talk openly with young people about the risks of cannabis

When to See a Doctor

Consider talking to a doctor or counselor if you find it hard to cut down on cannabis, if use is affecting your work, school, relationships, or health, or if you experience withdrawal symptoms when you stop. Also seek help if:

• You keep using despite wanting to quit
• Cannabis is being used to cope with anxiety, depression, or stress
• Use is increasing or involves high-potency products
• A loved one is concerned about your use

If cannabis use is accompanied by thoughts of self-harm or a mental health crisis, seek help immediately by contacting emergency services or a crisis helpline.
