Aesome replies so far guys, thank you. Another question, the roach is just w/e you use to keep from inhaling the weed right? I've seen people use just pieces of bent up paper (So that it looks like a spring \/\/\ ) and put it in the end. I've also seen people bend the end of it so that it looks kind of like =-====== so that there is just a little hole you can see through. Can anyone verify this kind of thing?

Also, you said don't buy ground cannabis and only get it in buds? What exactly would I have to do to it to smoke it if I got it in buds (and what do they look like compared to ground)?
