Primed for Addiction?

This article from Science questions the validity of claims about how drug addiction can adversely affect brain function. Researchers were interested to find if brain function that limits decision making and self-control was a product or a cause of drug use/addiction. The experiment compared brain scans of two siblings, one a drug user/addict and one not. The results show that addicts and siblings of addicts tend to show very similar scans. This suggests that there must be some other prevailing force (besides genetic factors) that inclines easily addicted personalities to use drugs. 

 This article might be a great primer for our lecture on Thursday.
