I just keep everything right out in the open on my desk. It all goes into pill bottles eventually, pills, weed, heroin, whatever... but those bottles stay on my desk. In fact, all of my drug paraphernalia stays on my desk... straws, pipes, pill-cutters, pill-grinders, everything.

That's pretty stupid. What if the police were to suddenly raid your house?
