Personally I keep everything I need in a pocket of my backpack, which goes everywhere with me. I have a small flat plate, a little box with credit card (and other cards like them) and a razor blade and finally, my bottle of pills. From what I can tell, it looks like a bunch of powder gets stuck up inside those pill grinders. The way I do it, everything I want to do ends up right on the plate. I actually snort from the plate, so it's all good. Call it a personal preference or whatever, I've always been most comfortable using this method (it's worked for me multiple times daily for probably 15 years). To each his own, I suppose.
