Twice as many adult Americans are smoking pot than 10 years ago.
That figure comes from a new report by JAMA Psychiatry (by the National Institute on Alcohol Abuse and Alcoholism), which surveyed people about their marijuana use in 2012-2013, and compared it to numbers from a decade earlier.
In 2001-02, the survey found the percentage of adults who said they'd used marijuana in the past year was 4.1 percent.
For the most recent study, that number jumped to 9.5 percent of adults. It also found 30.6 percent of those who'd used in the past year could be classified as having a marijuana use disorder – meaning there was abuse or dependence in connection with the drug.
JAMA broke it down by a bunch of characteristics, including age, sex, race/ethnicity and more. You can click the image on the right to see a full version.
Marijuana use in Minnesota
The JAMA report didn't dive into a state-by-state look, but did view it regionally.
In the Midwest, 9 percent of respondents said they'd used marijuana in the past year, below the national average and behind the West (11.9 percent) and Northeast (10.7 percent). The south came in at 7.7 percent.
However, some other surveys and studies have zoomed in further.
The website CheatSheet took data from a 2011-12 report the Substance Abuse and Mental Health Services Administration did. They then compared that to census data to get a percentage of the adult population that had used marijuana in the past month.
Minnesota came in at 6.22 percent. The four states with the highest percentages were up near 13 percent.
The Washington Post took the same report but looked at use by anyone age 12 and up. That moved Minnesota's rate to 6.3 percent.
And CBS News put together a list of 17 "stoner states," based on 2009 numbers – Minnesota did not make the cut.
Minnesota, of course, is one of 23 states (plus Washington, D.C.) that has legalized medical marijuana, ProCon says – though here, it can't be provided in smokeable plant form.
There have been questions about the program's cost. Insurance doesn't cover the medicine, and there are only a handful of dispensary locations around the state – meaning some patients face long drives.
In Minnesota, it’s available to patients suffering from one of nine serious conditions, including cancer, terminal illnesses and seizure disorders – though officials are considering whether to add “intractable pain” to the list.
Four states, plus Washington, D.C., have legalized pot for recreational use, CNN Money says.
