You forgot one: The companies that produce these pills figured out that it is a hugely profitable thing to be selling heroine in pill form (which is more or less what we are talking about) and have been heavily marketing their drugs to doctors and patients. As a consequence all of the things you list are happening and it is hugely profitable.

And when I say marketing here think ads on the tv, heavy lobbying with politicians, inviting doctors to exclusive events and pampering them, sponsoring studies on chronic pain, etc.
