Blunt wraps fuck up the weed.
Bongs are the most efficient way to smoke so why waste your weed? Vaporizors take away from the fun of smoking, they are too complicated and leave too much waste.
Not that I can't roll the sweetest joints you have ever seen but they are just a waste of smoke. And then there will always be a bogart on that joint if you smoke with friends, you know the guy. The one who has to hit it so hard that it runs halfway down the side, burning it unevenly and whatnot because he is so selfish and uncaring about the art of smoking.
