Denver Post: Marijuana use increases in Colorado, according to new federal survey (Dec 26, 2014)
As marijuana legalization took hold in Colorado, the estimated percentage of regular cannabis users in the state jumped to the second-highest level in the country, according to new federal data.
When asked, roughly one out of every eight Colorado residents over the age of 12 reported using marijuana in the previous month. Only Rhode Island topped Colorado in the percentage of residents who reported using marijuana as frequently.

Monthly use in Colorado jumped to 12.7 percent — a 22 percent increase — in the 2012-13 data. The result means the survey estimates about 530,000 people in Colorado use marijuana at least once a month.
Nationally, monthly marijuana use by people 12 and older nudged upward by about 4 percent to 7.4 percent. In Washington state — which, like Colorado, in 2012 legalized marijuana use and limited possession for adults — monthly marijuana use rose by about 20 percent to 12.3 percent....
A study commissioned by Colorado's Marijuana Enforcement Division this year found that people who use marijuana almost every day account for about 22 percent of cannabis users in Colorado but consume nearly 67 percent of the marijuana used. Other studies have warned about a possible uptick in heavy marijuana use....
