^Same here. I think both powder and uncut rocks could both be pure, however they could also be heavily cut and still resemble the real thing. Shooters can tell, smokers not so much (used to it melting and freezing in a certain way, as well as certain cuts add to the oomph, so they simply have to hit it a few more times for the desired oomph effect.)
I think that with powder, its harder to tell if its contaminated or not. Although contaminated meth could be turned into a heavily cut rock form. So its really hard to tell the real thing from pseudo/cut unless one is heavily experienced and tests it on themself. Something like an acetone wash, will not remove pseudo but will remove contaminants like ammonia, ether, iodine etc. Alot of times (in my opinion) they will not react the pseudo->meth fully or will go so far as to cut it with a pseudo-like substance, as it smokes the same and kind of cracks back the same. With pure or near pure though from what ive experienced, it cracks back like the same effect if you were to throw a baseball at a window and it doesnt fully crack, that ripple emanating outwards with lines parallel but not completely parallel, and its a foggy crackback and not clear.
