According to the National Survey on Drug Use and Health, 10.4 percent of Coloradans over the age of 12 said they’d used marijuana in the past month when asked during a period in 2011–2012. That figure jumped to 12.7 percent the next year, meaning that Colorado has the second-highest (heh) percentage of regular weed consumers in the United States. (Rhode Island is No. 1, while the national rate is a considerably less chill 7.4 percent.) The survey didn’t include numbers from 2014, the year Colorado’s recreational pot sales began, so it doesn’t tell us if usage increased with legalization — but it does at least partially explain how ol’ Amendment 64 passed in the first place.
