Five years after Colorado voters decided to regulate marijuana for adult use, rates of current and lifetime use among high school students remain relatively unchanged and on par with national averages
DENVER — A new federal report shows rates of teen marijuana use in Colorado have still not increased since voters decided to end marijuana prohibition in 2012 and start regulating it similarly to alcohol for adult use.
The U.S. Centers for Disease Control and Prevention’s High School Youth Risk Behavior Survey (YRBS) found 19.6 percent of Colorado students are currently using marijuana (compared to 19.8 percent nationwide), down from 21.2 percent in 2015 and 22 percent in 2011, the year before voters approved Amendment 64. The rate of lifetime use dropped to 35.5 percent in 2017 (compared to 35.6 percent nationwide), down from 38 percent in 2015 and 39.5 percent in 2011.
The Colorado and nationwide data for 2017 are available at https://tinyurl.com/y9kor29o. The CDC released the nationwide YRBS data late last week, and it appears to have released the state-level data sometime this week.
Statement from Marijuana Policy Project spokesperson Mason Tvert, who co-directed the campaign in support of Amendment 64:
"After five years of marijuana being legal for adults in Colorado, government surveys continue to find no increase in usage rates among high school students. This is very welcome news for Colorado, and it should be particularly welcome news for those who opposed the state's legalization for fear it would lead to an explosion in teen use. Hopefully it will allay opponents' concerns in other states where voters or lawmakers are considering proposals to legalize and regulate marijuana for adult use. Colorado is proof that you can prevent teen marijuana use without arresting thousands of responsible adult marijuana consumers every year. Rather than debating whether marijuana should be legal for adults, let's focus on how we can regulate it and control it to make it less available to teens."
