To hear just how arrogant and myopic a government functionary can be, simply listen to one in Florida.
A couple of years ago the government instituted a smoke-free zone on all their facilities as well, including the State hospitals which house the psych patients. Schizophrenics are notorious smokers because it "stops the voices" for up to 8 minutes with each cigarette. (this has been proven to be true)
One of the Dr's at the hospital where I did my nursing rotation said, "I liked these patients better when they could smoke. Now they are mostly unmanageable."
Soooo.... for the sake of being PC, the gov't is willing to let a perfectly legitimate substance be banned from a population which benefits from it the most. I guess we can keep doping them more......It's less offensive, right?
