If that is the only tangible difference, then doesn't imprisoning, shooting, robbing and destroying the people and property associated with the illegal drug trade while helping those associated with the legal drug trade (booze, prozac, feelgood prescriptions) seem like some sort of ultimate hypocrisy which will only cause the millions persecuted and imprisoned to one day stop respecting Society and Law and to start Shearing Sheep instead?
Your thought process is amoral and I can't agree with it.
