The problem that arises with legalizing marijuana is that while it may be legal under local governments, it still would be classified as a Schedule l drug at the federal level, which creates new problems on state/country regulation. Medical marijuana is still greatly debated, with a little more than a handful of states declaring it legal. People make the argument on both sides how legalization/regulation of it can either reduce/increase the usage of other drugs, crime, and economics, which is just asinine because many of the same things can and have been said about cigarettes and alcohol.
To declare cigarettes and alcohol legal while declaring marijuana illegal is foolish on many levels. To denounce the effect(s) that it has on people, while looking the other way with other drugs, is extremely close-minded. The after-effects of both cigarettes and alcohol have been studied and proven to last longer upon the human body than marijuana, and yet you can buy either of them at as young an age as 18 (legally).
I'm not necessarily for or against Prop 19. I admit that I've smoked weed before, it's not something that I really enjoyed or care about, but it's pleasurable every once in awhile (more often for others). I believe that it's something that could be introduced into society, if people stopped drinking, smoking, and pulled their heads out of their asses to have an open mind.
