Every few years, SAMHSA combines data from the annual National Surveys on Drug Use and Health to derive estimates of monthly marijuana use among Amer-icans age 12 and older. The latest cut of that data, encom-passing the years 2012 to 2014, includes responses from about 204,000 people. That huge sample makes it possible to visualize marijuana use rates with a level of detail not possible with traditional surveys. More than 15 percent of San Francisco residents age 12 and over use marijuana monthly or more often, the highest rate in the country, the survey found. By contrast, the lowest use rates are in the far south of Texas, where fewer than 4 percent use marijuana monthly. The report finds that nationally, 7.7 percent of people 12 and older - - roughly 20.3 million Americans - use marijuana at least once a month. Broadly speaking, marijuana use rates are high-est in the West and lowest in the South. "We continue to see relatively wide variation in marijuana use" at the sub-state level, said Art Hughes, a SAMHSA statistician and a lead author on the report. Overall marijuana usage rates were up by less than 1 percentage point over the period from 2010 to 2012. Marijuana use rates have become a hot topic since Colorado established the first legal marijuana market in 2014, with several other states following suit. Marijuana use in Colorado is relatively high, but it has been that way for a while. "There are some states where we see rates on the high end even before legalization," Hughes said. - -Washington Post - --- MAP posted-by: Jay Bergstrom
