Duke University study finds marijuana can permanently reduce IQ

The onset of medical marijuana becoming legal in Illinois on 1/1/2014 is putting many parents in the situation of having to convince their children of the harm of using marijuana, especially for adolescents whose brains are still developing.  Many students equate medical with healthy or at least okay to use.  Below is a link to recent compelling research from Duke University that documents the impact of marijuana use on individual IQ.  Hopefully this research will help parents discuss marijuana use with their children.

If you are inclined to not read scientifically published studies, you may enjoy googling “Duke University marijuana reduce IQ study” which will identify many other news sources who reported and summarized the scientific published results.

Please note:  This study was challenged for not factoring in socioeconomic, SES, status in their results.  Results were rerun with socioeconomic as a mitigating factor and the same results were found.
