I was wondering what color meth hcl turns into as soon as it starts melting. i came across some that turns into dark amber as soon as it melts and i was told its supposed to be clear and those are the impurities. is this true?
All depends how it was manufactured, my friend. Ideally, you want it clear or colorless. That's not always the case, however...but my rule of thumb is, if it burns shitty, snort it or shoot it.
I always vape it when I get a batch, and if it isn't clear/colorless, I let it recrystallize and snort it. I wouldn't bang meth that doesn't vape clear either.
