I just remembered this. The cheapest method of a vaporizer. Roll up a little bit of weed into a ball. Get a 20 oz plastic bottle, and cut the bottom off. Take two butter knives. Turn your stove on. Put the knifes in between the burners so they're supported on the burners. Let the knives get red hot. Scoop up the weed on a knife, and mash the knifes together and put it under the bottle so the smoke will rise up through it to the top, and inhale while you're doing this. It really only works with nugs, and gets you hella high. It's a lot easier if you have someone to help you.
