Cannabis Use Disorder Surges: 1 in 10 Men Affected

A significant increase in problematic cannabis use has been observed in the United States, according to a large national study. In 2024, approximately 9% of men and nearly 6% of women reported symptoms of cannabis use disorder, indicating a rise from 2021 figures. This disorder is characterized by an inability to cut back or quit cannabis use, even when interpersonal problems arise.

Experts attribute this trend, in part, to the substantially higher concentrations of THC, the psychoactive compound, found in contemporary cannabis products. This increased potency is making the addictive nature of cannabis more evident. Overall cannabis usage also rose, with 26% of men and 21% of women reporting use in 2024.

The study, published in JAMA Psychiatry, found that about 30% of individuals who use cannabis exhibit symptoms consistent with cannabis use disorder. This rate is notably higher than that for alcohol use disorder, where less than 20% of drinkers showed similar symptoms. The most significant increases in cannabis use disorder were observed among adults aged 35 to 49 and men aged 50 and older.

Currently, there are no FDA-approved treatments specifically for cannabis use disorder, though therapies like cognitive behavioral therapy and peer support groups are available. Researchers are concerned about the potential long-term effects of cannabis use disorder on the aging brain, particularly for middle-aged and older adults.
