How common is marijuana addiction?
- By Robert Mauer
- Reviewed by: Dr. Janaka Hanvey, PhD
Marijuana addiction is relatively common compared to many other illicit substances, largely because marijuana use itself is widespread. Research suggests that a minority of users—roughly 9–30% depending on age and patterns of use—may develop a substance use disorder.
The risk is higher among those who start young and those who use frequently. Daily or near-daily use significantly increases the likelihood of developing dependence or addiction.
Although many people use marijuana without developing a disorder, the number of affected individuals is substantial due to the high prevalence of use. This makes marijuana use disorder an important public health concern.
