Roughly 22 million American adults now use marijuana, double the number from a decade ago.
Pot use increased dramatically over the past 10 years, and now 10% of the U.S. public uses the drug, as more Americans say it should be legalized, according to a study published Wednesday.
Four states now permit recreational use and 23 allow medical marijuana.
The study found that certain groups recorded a larger increase in marijuana use than others.
Women overall and people between the ages of 45 and 64 were more likely to use the drug than a decade ago, as were blacks and Hispanics, plus people living in the South or those with lower-income, the study said.
Almost one in three users had signs of marijuana dependence or abuse, according to the report co-authored by Bridget Grant, of the National Institute on Alcohol Abuse and Alcoholism.
Some groups recorded a larger increase in marijuana use than others.
Although that was a slight decline from a decade ago, the authors warned that marijuana abuse or dependency was a concern.
“While many in the United States think prohibition of recreational marijuana should be ended, this study and others suggest caution and the need for public education about the potential harms in marijuana use, including the risk for addiction,” the study said.
“The clear risk for marijuana use disorders among users (approximately 30%) suggests that as the number of U.S. users grows, so will the numbers of those experiencing problems related to such use,” it concluded.
