Drug free's the way to be

So random musing:

Have you noticed that since the beginning of the "War on Drugs" there's be a rampant over-prescription of mind-altering drugs (depression meds, meds for ADD and ADHD, antibiotics even), that has been to such an extent there seems to be an epedemic of mental disorders in this country?

Is it just a coincidence or is there some meaning behind the "you shouldn't do drugs unless you're doing our drugs" message in the media?
