I saw a couple of brief news alerts indicating that progress toward reclassification of marijuana from Schedule I to III could be happening as soon as today according to a Reuters report. I think that means we should pay attention to other stories and reports of cannabis use being associated with higher rates of psychosis in adolescents. That information is not new and it has been reported since at least since 2010.
The DEA is in charge of reclassification of substances.
