Marijuana Use, Disorders Double in US Adults

The prevalence of marijuana use among US adults more than doubled over a 12-year period, from 2001 to 2013, new research suggests. Prevalence rates rose from 4.1% in 2001 to 9.5% in 2013, according to similarly designed studies conducted 12 years apart.

Over the same period, the prevalence of marijuana use disorders (abuse or dependence) nearly doubled, from 1.5% to 2.9%.

“Most Americans see marijuana, a natural substance, as harmless, but it is not. Some can use without harm, but it’s important for healthcare professionals, policy makers, and the public to be aware that users are at risk for addiction. This should be communicated not with scare tactics but in a balanced manner,” Deborah Hasin, PhD, lead author and professor of epidemiology at Columbia University, in New York City, told Medscape Medical News.

The increased prevalence of marijuana use (defined as any use during the past year) across the population was also felt across most population groups. The study noted that increases were most pronounced among women (from 2.6% to 6.9%), African Americans (from 4.7% to 12.7%), Hispanics (from 3.3% to 8.4%), and older people (from 0.04 to 1.3%).

The study was published online October 21 in JAMA Psychiatry.
