Well, marijuana is no worse than alcohol. But alcohol to excess is pretty bad too.
The problem is other drugs. Once you legalize pot, the druggies will want a bigger high and the drug pushers will push marijuana laced with other stuff - plus the other stuff.
Marijuana use itself should be decriminalized as long as what you are using is pure marijuana and not anything else.
The amount of MONEY, COURT TIME, JAIL SPACE, COP SALARIES AND BENEFITS that expended in the flawed “War on Drugs” would help balance the budget.
Decriminalize marijuana use, take people who use the other stuff and dump them on a desert island somewhere with all the poppy seeds they want, and take your fingers out of my wallet and your cops out of my life.
Not as harsh as the one I propose as an alternative to the death penalty for those deserving of it. See my FReeper profile.
