I got an idea, don't take the drugs and there wont be a market.

In the world we live in everyone wants a quick and easy solution... they dont want to actually deal with a problem so they take a pill to do the work for them. As long as there is the delusion that a hand full of pills will make you thin, smart, relaxed, attentive, good looking, interesting, energetic and hard as a phallic shaped diamond, there will be the masses waving their gubment vouchers to get them.

I will leave it to Mr Waits to explain the pharmaceutical companies stance...
