Preparing myself for an upcoming lecture by Professor Deborah Cobb-Clark here at the Jahrestagung des Vereins für Socialpolitik 2014 (Association of German Economists) I came across an interesting paper. It is about the relationship between early marijuana use (at age 14 or younger) and young people’s educational outcomes.
„Early marijuana use is associated with significantly lower university entrance score.“
„We provide evidence that this effect is unlikely to be driven by selection. Collectively, these findings point to a more nuanced view of the relationship between adolescent marijuana use and educational outcomes than is suggested by the existing literature.“
