Abnormalities in the brain may make some people more likely to become drug addicts

Abnormalities in the brain may make some people more likely to become drug addicts, according to scientists at the University of Cambridge. They found the same differences in the brains of addicts and their non-addicted brothers and sisters. The study suggested addiction is in part a "disorder of the brain". Other experts said the non-addicted siblings offered hope of new ways of teaching addicts "self-control".... BCC News
