I wish I could say I didn't see this coming. A few years ago I worked in a methadone clinic which treats people with opiate dependence. It quickly became apparent that the prescription drugs OxyContin and Xanax were more problematic than the heroin we were treating. Even on my small case load one of my clients died, another lost 60% of his kidney function and many others suffered serious impairments to functioning.
Doctors who "sell" presciptions for cash should be dealt with. But this doesn't address the real problem, why do people want to bombed out of their minds? If someone wants to be unconscious, they are going to achieve that end. If they don't get prescription drugs they are going to use street drugs or drink themselves into a coma.
Better mental health treatment and a focus on dealing with the psychic pain which causes people to seek numbness is the permanent solution.
