Methylone insufflation... I had to start a separate thread on this, because he believes to have discovered the secret to worthwhile snorting of this substance: Chop it up extremely well. Using the blunt edge of a razor blade, credit card or something similar on a hard surface like glass, scrape the crystals really hard by both pressing down and rubbing them laterally against the glass.... first in one direction, then in the other, then continue to repeat. There will be a soft crunching sound as the crystals are crushed. It's possible that a mortar/pestle would work too. The crystalline solids should be turned into an extremely fine dust. Take 5-10 minutes to do it, if necessary. I found that after doing this, insufflation of a small amount resulted in immediate effects, like coke. He suspects the crystals are normally too large/heavy to be soluble enough or adhere properly to mucus membranes, but this procedure fixes the problem. Note that this also causes maybe 20% to adhere to the inside of a straw, so be sure to tap the end of it on a hard surface afterward to recover the extra. Any you's trying this who can corroborate SWIM's findings?
