Seeing him strung out on opiates (edit: turns out it was benzos) made you get off opiates?
The man doesn't need to explain himself to overly left left wing redditors looking to try to take him down a notch or prove him wrong. I only metion redditors as your comment on benzos is the single most popular item to bring up in a discusson about him. His years of work and masses of public statements and appearances get dismissed with a single, ill informed snarky one-liner. The man is a treasure.
Additionally there is a large boxy of work for prescribing Benzodiazepines to treat pain, as well as pairing the two for chronic pain, which seems to be an absolute recipie for disaster if used for anything but the shortest periods of time.
