Cannabis legalization has led to a boom in potent forms of the drug that present new hazards for adolescents

As a professor of psychology, I focus my research on substance use in adolescents and young adults. A major change during my time in research is the legalization and explosion of cannabis availability across the U.S. There are arguments for and against increasing legalization of cannabis for adult use in the U.S., but expanded access to legal cannabis also may have unintended consequences for adolescents.
