This may shock you, but Colorado and Washington residents don’t use the most weed (if you’re measuring by the percent of state residents who regularly use marijuana.) Rhode Islanders do.

Thirteen percent, or one in eight, of those over age 12 in The Ocean State said they had used marijuana in the past month, according to state-level statistics from the latest National Survey on Drug Use and Health. This is a big jump from the national average, which is about 7 percent. Kansas reported the lowest levels of regular marijuana users at 4.06 percent overall.

Though Rhode Island came in as a dark horse, the rest of the statistics are less surprising: According to The Washington Post, Western states generally have the highest rate of weed usage, at 9 percent, followed by the Northeast. The South has the lowest overall rate at 5.83 percent.

Another not-so-shocking find was that the largest age group using weed is the 18-25-year-old bracket. Nineteen percent of this group has used marijuana in the past month. This is a sharp contrast from Americans 26 and older, where only 5 percent reported using marijuana regularly.

These findings do vary pretty significantly state-by-state, however. For example, just 9.83 percent of 18- to 25-year-olds in Utah report using marijuana regularly, compared to the 11.8 percent of the over-26 crowd in Alaska. So the older crowd in Alaska is more likely to use weed than the college crowd in Utah. This isn’t too shocking though, since marijuana’s legalization is on Alaska’s 2014 ballot.
