One difference between a pothead and drinker is life expectancy. But in any case, I never did buy the pretend two wrongs make a right argument. Beer is bad – so I’ll legalize LSD & pot? Not buying it.
Actually, my argument is the converse: Beer (and wine and whiskey and rum and...) isn’t bad, so why is pot?
Also, we allow lots of things that significantly reduce life expectancies, from cigarettes to gay sex to motorcycles. I just don’t see that as an anti-pot argument.
The way I see it, Law Enforcement, in its war against (some) drugs is more of a threat to life, liberty, and property than potheads and legalized pot. It is not that I’m crazy about legalizing pot, but that I’ve had it “up to here” with cops kicking down doors and coming in with weapons ready over pot.
