Marijuana use can lower educational outcome

Early marijuana use is associated with significantly lower university entrance score."
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.

Key lesson:

„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.“
