Cannabis Use Disorder

Overview

Cannabis use disorder is a medical term for when using cannabis (also called marijuana, weed, or pot) starts causing serious problems in your life and you find it very hard to stop, cut down, or control your use, even though it hurts your health, work, school, or relationships. It is a real condition, not a personal weakness.

Yes, it is one of the most common substance use problems. Many people who use cannabis regularly will experience at least a few signs of the disorder, though the full condition affects about 1 in 10 people who have ever tried it.

It can affect anyone, but it is most common in teenagers and young adults, especially those who start using cannabis in their early teens. Men are more likely to be affected than women, but the gap is narrowing.

Symptoms

Common symptoms

• Strong cravings or urges to use cannabis
• Using more cannabis than you intended, or for longer than planned
• Spending a lot of time getting, using, or recovering from cannabis
• Wanting to cut down or stop, but being unable to do so
• Missing work, school, or family events because of cannabis use
• Continuing to use cannabis even when it causes arguments, money problems, or health issues
• Needing more cannabis to get the same feeling (tolerance)
• Feeling irritable, restless, or having trouble sleeping when trying to stop (withdrawal)
• Giving up activities you used to enjoy in order to use cannabis

• Feeling confused or dizzy, leading to falls
• Interacting less with friends or family
• Using cannabis to treat pain, sleep, or anxiety without medical guidance
• More difficulty managing everyday tasks like bills or medications

Causes

Main causes

• Cannabis changes brain chemicals that affect mood, memory, and motivation, and some people's brains react more strongly than others
• Using cannabis at an early age, especially before the brain finishes developing
• Using it frequently or heavily over time
• Genetics: a family history of substance use problems can make you more vulnerable

Risk factors

• Starting cannabis use in your teens
• Using cannabis daily or multiple times a week
• Having another mental health condition like anxiety, depression, or ADHD
• Trauma or high stress in childhood
• Having friends or family members who use cannabis heavily
• Low self-esteem or difficulty coping with stress

When to see a doctor

See a doctor urgently if:

• If you feel you have lost control over cannabis use and cannot stop even when it is dangerous
• If you are having thoughts of self-harm or suicide
• If you experience severe withdrawal symptoms when you try to stop

Book a routine appointment if:

• If you are worried about how much or how often you use cannabis
• If your relationships, job, school, or health are being affected by cannabis
• If you want to cut down or stop but need help to do it

Diagnosis

A doctor or mental health professional will ask you about your cannabis use, how it affects your life, and how you feel when you try to stop. They will also rule out other possible causes for your symptoms, such as anxiety or depression.

Tests that may be done

• There is no blood test or scan that can diagnose cannabis use disorder
• Your doctor may use a short questionnaire to help check your patterns of use
• They may ask you about your mood, sleep, memory, and daily activities

What to expect at your appointment

The visit is a conversation, not a test. The doctor will listen, ask some personal questions, and then talk with you about next steps. You are in control of the discussion, and you can be as open as you feel comfortable.

Treatment

Treatment for cannabis use disorder usually focuses on counseling and behavior change. It helps you understand why you use cannabis, find new coping skills, and build a life with less reliance on the drug. Some people benefit from medicines to ease withdrawal or cravings, but this is decided together with your healthcare provider.

Self-care at home

• Be honest with yourself about how much and why you use cannabis
• Set small, realistic goals, like reducing your use by one day per week
• Find alternative activities that keep your hands and mind busy, such as exercise, hobbies, or time in nature
• Talk to a trusted friend or family member about what you are going through
• Keep cannabis out of easy reach, and avoid places or people that encourage you to use
• Practice stress-relief techniques like deep breathing, journaling, or meditation

Medical treatments

Your healthcare provider may talk about behavioral therapies, such as cognitive behavioral therapy, which helps you change the thoughts and habits behind your cannabis use. They might also discuss medicines that can help with withdrawal or cravings, but they will always explain the options, possible side effects, and what is right for you. Never start a medicine without a doctor's advice.

Living with this condition

Living with cannabis use disorder means taking it one day at a time. You may have cravings or setbacks, but that is normal. Try to keep a steady routine, stay busy, and celebrate small victories. If you slip up, do not give up — recovery is a process, not a straight line.

Lifestyle tips

• Build a daily routine that includes regular meals, enough sleep, and planned activities
• Exercise regularly, even a short walk, to boost your mood and reduce cravings
• Avoid using other substances, including alcohol, that can lower your willpower
• Practice saying no to offers of cannabis in a calm, confident way
• Stay connected with people who support your goal to change

Diet and exercise

Eating balanced meals and staying active can help stabilize your mood and reduce stress. A healthy diet and regular exercise also help repair the brain's reward system, which makes it easier to cope without cannabis.

Mental health and emotional wellbeing

Cannabis use disorder often comes with anxiety, depression, or low motivation. It is important to talk about your mental health with your doctor or a counselor. Treating both the substance use and any underlying mental health conditions together gives you the best chance at recovery.

Prevention

Cannabis use disorder can often be prevented. The strongest way is to delay trying cannabis until adulthood, and to avoid frequent or daily use. If you already use, reducing how often and how much you use lowers your risk. Talking openly about risks and having healthy ways to cope with stress also help.

Complications

If left untreated

• Worsening memory, concentration, and learning problems
• Lower motivation and difficulty holding a job or doing well in school
• Mood problems such as anxiety, depression, or panic attacks
• Strained relationships with family, partners, and friends
• Financial or legal trouble related to buying or possessing cannabis
• In young people, increased risk of long-term mental health problems

Long-term outlook

The outlook is very positive. Most people who get help can learn to control or stop their cannabis use. With time and support, your memory, motivation, and relationships can heal. Even people with severe cannabis use disorder can recover and live full, satisfying lives.
