The down side to this is when coke is clean it has an unmistakable sheen to it so you know it's legit. Sort of looks like a dull gloss, the best thing I can compare it to is spray foam insulation (I earlier mentioned sheetrock - yall probably think I'm a construction worker . The powder doesn't sheen though so when you mix rocks with powder the powder coats it and makes it look dull which makes it look less authetnic. I can ship powder in with the rocks as long as everybody promises to dust it off with a turkey baster first! jk - dust it if off if you want, or just shove the entire thing up your nose in one go if you like, whatever your preference.
