Personally I have myself a pill splitter/crusher. Very handy. If I feel like switching things up a bit, I'll do what I used to without my pill crusher; get a notebook, book, magazine, whatever. Choose a good place within it, fold a few pages in half and open them back up. Break pill into as many pieces as possible on chosen pages, fold pages back over, crush with something hard, i.e. lighter. Tap pages a little bit, and then continue to crush. Unfold the pages, and snort.
