Trouble is, you're right (addiction attacks a genetic mental weakness in certain people) but you are missing a lot of the systemic problem: prescription opioids.   Doctors have blood on their hands of millions for Rxing opioids for so many normal productive people whom are now addicts as a result of these prescriptions!  I am talking hard working middle class, working poor, wealthy professionals too, who had pain or injury and some dumb doc gave them oxy.  Now they are hooked and we have suburban mom n pop dying together after work in their middle upper class surburban homes with 2 cars in the garage and 2 kids wondering what just happened.  This is very alarming and infuriating .. and could have been prevented!!
