Many people still believe marijuana is not addictive, but research shows that regular use can lead to cannabis use disorder (CUD), especially when use begins in adolescence.(Source) CUD is a diagnosable condition in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), meaning it is recognized as a real substance use disorder.(Source)

Current estimates suggest that about 3 in 10 people who use marijuana will develop some degree of cannabis use disorder, and the risk is higher for those who start using in their teens.(Source) Young people are particularly vulnerable because the areas of the brain involved in decision-making, impulse control, and judgment are still developing through the mid-20s.(Source)

Illegally obtained or unregulated marijuana products may also be contaminated or mixed with other substances, such as synthetic cannabinoids or opioids, which can increase the risk of dependence and serious health consequences.(Source)

Occasional marijuana use does not automatically mean someone is addicted. However, frequent or heavy use—especially daily or near-daily use—can become habit-forming and may progress to addiction when a person:

• Feels unable to cut down or stop
• Spends a lot of time using or recovering from use
• Continues using despite problems at school, work, or in relationships

If you notice these patterns in yourself or your child, it may be time to talk with a professional about treatment options.
