Personally, I think an acetone wash is the best way to determine quality. Plus, you get clean meth.
I live on easy coast, crystalis slowly making its way and it's becoming a bigger problem however the quality is not that good at all or at the most decentYeah it is. Just recently been seeping into the East Coast.
I even talked to a kid from Indiana who used to shake his own shit, and he said the stuff in Boston is garbage, like i suspected.
I've bought from ~3 dealers locally and ~8 dealers in the US from the dark web, and all the shit was very similar. Not bad.. it's still my DOC despite it being not high quality, but i'm definitely going to wash my next batch.
