Cannabis Use Disorder

Definition: Cannabis use disorder (CUD) is a diagnosable condition in which a person has trouble cutting back or stopping cannabis use even though it’s causing problems with health, work, school, or relationships. It ranges from mild to severe. The CDC estimates that about 3 in 10 people who use cannabis have cannabis use disorder.

What Are the Signs of Cannabis Use Disorder?

• Using more cannabis, or for longer, than you meant to
• Trying to cut back or quit without success
• Spending a lot of time getting, using, or recovering from cannabis
• Strong cravings
• Needing more to get the same effect, a sign of rising tolerance
• Continuing to use even when it causes problems at home, work, school, or in relationships

Who Is Most at Risk?

According to the CDC, risk is higher for people who start using in their teens and for people who use more often. NIDA notes that frequent, heavy use of THC products is the strongest predictor. Higher-potency products such as concentrates may add to that risk, though research is still developing.

Is There Cannabis Withdrawal?

Yes. People who stop after heavy or long-term use can have withdrawal symptoms such as irritability, anxiety, trouble sleeping, headaches, and sweating. NIDA notes this can happen even without a CUD diagnosis. Symptoms are usually temporary. Persistent severe vomiting in heavy users may instead point to cannabinoid hyperemesis syndrome, which needs medical attention.

How Is Cannabis Use Disorder Treated?

CUD is treatable, and many people recover. Behavioral approaches such as cognitive behavioral therapy, motivational enhancement therapy, and contingency management have the strongest evidence. There are currently no FDA-approved medications for CUD, though research is ongoing.
