Quick hit: "Changing Demographics of Marijuana Initiation"

Some recent highlights and curiosities from the amazing world of cannabis science and therapeutics.

The development of legal cannabis is associated with lower teen use and higher adult use. But many scientists, hesitant to give up a lifetime of prohibition, spin their data to emphasize danger. One study from 2017 had shown that attending college is a risk factor for trying cannabis, and suggested that political acceptance of cannabis is promoting use among college students. But this interpretation was taken to task by a scientist at Washington University in St. Louis. The total levels of cannabis use have not changed much since 2000. The increase in college cannabis initiation is matched by a decrease in the number of high school students trying cannabis for the first time. In other words, college may now be a risk factor for trying marijuana because of a successful public health effort to reduce use among high schoolers. They simply wait a few years longer before trying cannabis for the first time. As the commentary points out, Given that later initiation is associated with decreased risk for drug-related problems, there may even be a case for cautious optimism.
