Not too sure if this is allowed please remove if it isnt. Ive seen "blackish" molly being sold on AB and ive recently acquired some on the street and I tested it with marquis and mandelin and it went straight to black. Im still skeptical as to why its so black. It literally looks like a piece of coal... Should i be worried and what causes the molly to be so black?
In chemistry, sometimes you need to apply heat to speed up the crystallization/drying process. Those bits are still effective, but slightly charred. You don't really notice it unless you see 50g+ of the same batch at once though.
