This is Your Brain on Drugs

According to a recent study by University of Pensylvannia scientists, there were “small or limited associations between [adolescent] cannabis use and structural brain measures.” But even calling the effect small is aggrandizing harms. Their data didn’t support the notion that teens using cannabis causes any changes in the developing brain. The report goes on to say that “Detailed studies of vulnerability to structural brain alterations and … long-term risk are clearly indicated,” which is directly refuted by their own data.
