the answer to the last question depends. what i do when i have nothing "professional" to use is get a soda can. empty it/wash it out, and make an indent in it that flattens out (or a little less or more than flat, don't worry about being exact). after that take a thumb tack, and poke about 10-15 small holes in the center of the indentation. then just put the weed on top of the holes, and breathe it in with the place that you would normally drink out of.

kinda difficult explanation, maybe someone else will give you a better one.
