Drugs don't manufacture thoughts like kill, steal, lie etc. They make it easier to act on existing emotions or thoughts already in someone's head. Addicts are already impulse control challenged,Not everyone with a history of addiction exhibits violence. But a former addict in a position of power can ruin lives by making bad decisions.
