If "mind altering substances destroy", then there must be an awful lot of doctors and pharmaceutical companies in this country who are just itchin' to destroy someone.
The fact is that the drug that killed Hoffman is just another version of the same exact opiate drugs that are prescribed millions of times in this country to treat a variety of ailments ranging from back pain to depression. In fact, one of the leading causes of heroin addiction is the removal of a legal opiate prescription because the prescribing doctor thinks the patient doesn't need it anymore or he's afraid of the patient himself becoming addicted to the prescribed drug. The patient is desperate (because, duh, they've become opiate addicted), and the one remaining option available to them is being sold by a scruffy dude down on the corner instead of a credentialed dude in a white smock.
There is a well-known radio personality - an "entertainer" he calls himself but we all know he's much more than that - who went down this same road several years ago. He used a variety of fraudulent prescriptions to amass some 4,000 Oxycontin pills. To my knowledge, he never suffered any
legal consequences even though his actions were most certainly against the law. (Oddly, he never talks about that when he's chastising other lawbreakers, like those dastardly illegal immigrants, but that's another story.) His vast wealth and army of acolytes afforded him options most addicts don't have. There's a lesson in there somewhere, if we but choose to listen.
