The New York Times reported (Roni Caryn Rabin, As More Americans Turn to Cannabis, Problem Use Is Increasing, NY Times, August 19, 2026):
"The study, based on nationally representative data of U.S. adults, found that more than 9 percent of the men — or almost 1 in 10 — reported symptoms of cannabis use disorder in 2024, up from about 7 percent in 2021. The prevalence of cannabis use disorder also rose among women, increasing to nearly 6 percent in 2024, up from about 5 percent in 2021. Symptoms of the disorder include not being able to cut back or quit, or continuing to use the drug despite it leading to interpersonal problems."
According to the Times:
"The researchers classified survey participants as having a moderate to severe cannabis use disorder if they reported at least four out of 11 symptoms. Users who reported two to three symptoms were considered to have mild cannabis use disorder.
"Some of the steepest increases in the prevalence of both mild cannabis use disorder and the more severe form occurred among men and women 35 to 49 and men 50 and older."
