OK, I bought the book, "Medical Marijuana Handbook: A Guide to Therapeutic Use" by Ed Rosenthal, a great book so far, has the medicinal uses, effects, myths, cooking, purchasing and preparing, and a chapter on a personal garden. Anyway, I lost my place in it, so I was flipping through, and stuck in the page on different kinds of joints was a single zig zag paper. Too bad I'm out of bud.
I saw that in a headshop near my house, I was very tempted to buy it! I may just do that now that you've given it a good review.
