No!  Because the war on drugs is far more damaging than any harm it might do to individuals.
And as far as prostitution goes, the vast majority of America women are all prostitutes at heart. I haven't met a women in my entire life that did not consider her body a commodity to sell to the highest bidder. The way I see it the prostitution laws are a lot like the banks prosecuting a counterfeiters. It's just a way to eliminate competitors. A prostitute is just a woman that places less value on her body (sex) than a woman that holds out for a bigger better deal like a house, a car, and control. Prostitution laws merely work to maintain the female monopoly on sex and should be eliminated.
