I know that on paper snorting it is a waste but part of it all for me is getting my card out, chopping away until fine and lining it up, it's almost ritualistic in that sense. Just like I imagine a smoker enjoys making their tooter and tray or an injector likes preparing a shot. I am lucky that I don't have a habit and have a low tollerence so still get a lot from snorting.
Each to their own really. Meh.
