How addictive is marijuana?

Marijuana can be addictive, though its risk is generally lower than that of substances such as opioids, nicotine, or alcohol. It can lead to a substance use disorder characterized by impaired control, continued use despite harm, and difficulty cutting down. The likelihood of developing a problem varies based on patterns of use and individual factors.
Not everyone who uses marijuana develops addiction, but a meaningful minority do. Risk is higher with frequent use, higher-potency products, and earlier age of initiation.
Addiction to marijuana exists on a spectrum from mild to severe. Even when considered “less addictive” than other substances, it can still lead to significant impairment and should not be dismissed.
