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.
The results come from the National Survey on Drug Use and Health and represent the average of estimates gathered in 2012 and 2013.
The numbers are among the first measurements of marijuana use in Colorado to be released after it became legal in late 2012 for people over 21 to use and possess marijuana in the state.
