Cannabis use disorder is increasing in the US, according to new data.
9,3 percent of men and 5,6 percent of women over 18 in the US report Cannabis Use Disorder, the most recent studies find (up from 7,3 percent and 4,5 percent, respectively).
There was also an increase in moderate-to-severe cannabis use disorder, from 3,1 to 4,1 percent among men, and from 1,7 to 2,5 percent among women.
This increase parallels an increase in past year cannabis use from 22,2 to 25,7 percent in the four year period.
The reasearchers also looked at Cannabis Use Disorder in the group of past year cannabis users (excluding all non-users). They found that among men, the share with CUD had increased from 32,9 to 36,2 percent. Among the youngest age group (18-20 years) 50 percent of past year users reported Cannabis Use Disorder.
Similar trends - though at lower levels - could be seen among women. Past year use increased from 17,7 percent to 21,2 percent in the four year period, while CUD increased from 4,5 to 5,6 percent.
During the same period Alcohol Use Disorder remained relatively stable or declined in some groups.
Among young adults (18-20 years), Cannabis Use Disorder is now more common than Alcohol Use Disorder, despite higher prevalence of alcohol use. A majority of young adults with Cannabis Use Disorder presented with moderate to severe CUD, whereas most young adults who presented with Alcohol Use Disorder had mild symptoms.
This cross-sectional study investigates age- and sex-specific trends in the prevalence and severity of alcohol and cannabis use disorders among US adults.
