This is one of the stupidest things I've heard. taking the risk away would make it less fun? Do you honestly think that when you go get stoned? "omg, the police could totally catch and arrest me, this is SOO much fun."
Plenty of reasons for legalizing, all of which have been mentioned. It got prohibited in the first place for bullshit reasons, less harmful than many things which are legal, and the drug war has been failing miserably, govt, could be MAKING money on this, and instead they're spending millions and millions of dollars trying to enforce bogus laws. Government needs to open its eyes and see they can't poke their heads in through every private citizens door and tell them what they can and cannot do.
