Study Reveals Significant Rise in Cannabis Use Disorder Among U.S. Adults
A recent study published in JAMA Psychiatry indicates a notable increase in cannabis use disorder (CUD) among adults in the United States. The research, which analyzed nationally representative survey data from nearly 187,000 adults between 2021 and 2024, found that the number of U.S. adults with CUD rose from an estimated 15.3 million in 2021 to 19.4 million in 2024. The prevalence of CUD among men increased from 7.3% to 9.3%, and among women, it rose from 4.5% to 5.6% during this period. Increases in moderate-to-severe cases were also observed, with rates climbing from 3.1% to 4.1% for men and 1.7% to 2.5% for women. These increases were particularly pronounced among adults aged 35 to 49 and those 50 and older. The study also noted an overall rise in cannabis use, with 25.7% of men and 21.2% of women reporting use in 2024, up from 22.2% and 17.7% respectively in 2021. This trend contrasts with alcohol use disorder, which remained stable or declined during the same timeframe.
