Fuck legality when it comes to something as trivial as sitting around smoking a plant.
Ever wonder why nobody takes any of your arguments seriously? When you start out with stuff like 'Fuck legality', that should be your first clue. The fact is, it is still illegal in a lot of places, and as such, will be enforced. Until then, whether we like it or not, those laws have to be followed.
I think weed should be legal, too. But I always laugh when people try to use the "It's only a plant" excuse.
Cocain comes from a plant, too. So does heroin.
There are plenty of reasons why it should be legal. But throwing out "It's only a plant" is lazy and stupid.
