Surprise, surprise. Looks like more than twice as many as you are puffing the magic dragon as you were ten years ago, according to a new report from JAMA Psychiatry.

While only 4.1% of American adults surveyed used marijuana in 2001-2002, 9.5% said they had used marijuana in 2012-2013, meaning approximately 1 in 10 adults in the US get high at least occasionally. The substantial increase of weed usage was observed across all demographics, according to the report, meaning that regardless of “sex, age, race/ethnicity, education, marital status, income, urban/rural, and region” more people smoke the ganj now, one of the few commonalities you can observe in our increasingly divided society.

The report of course doesn’t take into account the last two years. If usage has continued to increase at a similar rate (and it likely has), then getting blizazed can now be observed in over 10% of Americans.

The study finds the rise in the THC content of America’s collective blood to increasing permissive attitudes in the country, meaning since people are more and more cool with it, more and more people are doing it.

But it’s not all good news for weed celebrators and profiteers. The study also discovered an increase in a prevalence of “marijuana use disorder” over the last decade. That disorder is defined as being unable to stop using marijuana though you want to and believe it is harmful to your health. The number of people exhibiting weedaholism has risen from 1.5% to 2.9% of Americans, again across race/creed/education/sex/etc. It also finds that nearly 1 in 3 chronic users of cannabis exhibit some symptoms of this disorder.

The report does not disagree with ending recreational cannabis prohibition in the states, but does advocate increased caution and public education regarding its benefits and risks, saying that “as the number of US users grows, so will the number of those experiencing problems related to such use,” and “This information is important to convey in a balanced manner to health care professionals, policy makers, and the public.”
