Colorado is second in the nation when it comes to regular marijuana users ages 12 and up, according to the National Survey on Drug Use and Health Survey data from 2012-2013 showed marijuana monthly use increased by 22% from 2011-12.   California policy expert and professor, Mark Kleiman, tells the Denver Post that the long-term impacts of marijuana legalization have yet to emerge as such surveys don’t reflect the various forms of marijuana being used.   According to the survey, monthly marijuana use in Colorado has gone up for all ages.   Washington state also showed a 20 percent increase.

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. But because they do not include data from this year, the numbers aren’t able to answer the question experts have watched Colorado closely for: How will widespread commercial sales of marijuana impact use?
