In March 2016, U.S. News & World Report named Denver the #1 best place to live in the United States. The only other Colorado metro area large enough to be considered, Colorado Springs, was ranked #5.
In February 2017, the Colorado Department of Public Health and Environment reported that the rate of marijuana use among adults and adolescents "has not changed since legalization either in terms of the number of people using or the frequency of use among users." Rates of daily or near-daily use among adults were much lower for marijuana than for alcohol or tobacco, and the rate of past-month marijuana use was lower than past-month alcohol use among adolescents. "Based on the most comprehensive data available, past-month marijuana use among Colorado adolescents is nearly identical to the national average," the report concluded. In a December 2015 interview, the head of the National Institute on Drug Abuse (NIDA), Nora Volkow, acknowledged that marijuana usage rates have not risen despite changes in policy and public attitudes: "All of those factors have led many to predict that there would be an increase in the pattern of use of marijuana among teenagers and we are not seeing it."
The Colorado Department of Education reports high school graduation rates have significantly increased and dropout rates have significantly decreased since 2010.
Regulated marijuana sales generated nearly $200 million in state tax revenue and license fees in 2016, according to the Colorado Department of Revenue. This does not include tens of millions of dollars in local taxes and fees that were raised by cities and towns throughout the state. For example, the Denver city government reports that it received more than $29.5 million from local marijuana taxes and licensing fees in 2015. This was more than enough to cover the city's costs of enforcement, regulation, and education, which were about $6.9 million that year and are estimated to be around $9.1 million in 2016.
The Colorado Legislature distributed approximately $220.8 million in marijuana tax funds in FY 2015-16 and FY 2016-17, according to a July 2016 report from Legislative Council Staff. Less than 10% of those funds ($21.5 million) were needed to cover the costs associated with regulating marijuana. More than $138.3 million was distributed to the Colorado Department of Education to benefit Colorado schools, including $114.9 million for the Building Excellent Schools Today (BEST) public school construction program.
