I've never been there, man, never... I crush a pill and snort it, all of it, leaving not the tiniest spec of it or even some unidentifiable crumb too far away from "the scene," so to speak, to have been part of the pill but that nonetheless could still be, in my mind, some of the pill...
I'm just kidding lol honestly, I just leave it on a mirror, on my dresser, or on my desk and cover it with something. If I have to take it with me, then I'll make a tiny paper envelope or something and then wrap it in tinfoil just to be safe...
