Notable CDC survey data showing no changes in youth marijuana use despite massive state changes in marijuana law and policy

Via Tom Angell, the founder of Marijuana Majority, I just saw this interesting data report from the Center For Desease Control under the heading "Trends in the Prevalence of Marijuana, Cocaine, and Other Illegal Drug Use, National YRBS: 1991—2015." For those who do not know, the YRBS refers to the nation Youth Risk Behavior Survey which "monitors priority health risk behaviors and "is conducted every two years during the spring semester and provides data representative of 9th through 12th grade students in public and private schools throughout the United States."

The first three lines of data from this link will be of greatest interest to marijuana reform advocate, as it reports from the last 25 years the survey results on the issues of how many high-schoolers have "Ever used marijuana (one or more times during their life)" and have "Tried marijuana before age 13 years (for the first time)" and "Currently used marijuana (one or more times during the 30 days before the survey)."  Though I am simplifying the particulars, for all these survey questions, it appears that teen use of marijuana as reported via these surveys generally increased some in the 1990s and generally decreased over the last 15 years. And, of particular note, the CDC report that from 2013 to 2015, these was essentially and statistically speaking "No change." (Also, encouragingly, it appears that use of harder drugs by teens is also either not changing or even "decreasing" in recent years.)

Long story short, while adult use of marijuana is being legalize recreationally in a few states and medically in many more, it appears that so far we are seeing no obvious impact on teen use of marijuana.   I am not confident that these trends will persist over a long period of time if marijuana is legalized for recreational use by adults nationwide, but for now there is preliminary data to contradict assertions by opponents that marijuana reform that reform will be leading to significant increases in use by underage populations.
