- Is marijuana a "gateway" to other drug use? Not so much, according to new research, and "over-criminalizing" its use can contribute to young adults' use of other illicit drugs. According to the study, race and ethnicity are the best predictors of whether someone will use illicit drugs besides marijuana: non-Hispanic whites are more likely to use them than are (in order) Hispanics or African Americans. Furthermore, although marijuana use in one's teen years might lead to use of other drugs, youth apparently "age out" of that when they reach 21. Unemployment is a factor too, which suggests that, as one researcher concluded, "over-criminalizing youth marijuana use might create more serious problems if it interferes with later employment opportunities."

- Teen use of alcohol and drugs can be significantly reduced with brief, school-based interventions by mental health therapists or even by teachers given minimal training, according to a new study from the U.K. Researchers evaluated their use of alcohol and drugs at six months post-intervention, so it's not clear if the effects would need to be repeated on a regular basis.
