Well nothing can every be 100% pure but what I imagine you mean is something close to that, high quality mostly pure meth and yes it does exist. Meth right now is cheaper and more available than ever. I know theres an argument to be made that the synthesis is different which creates a different high and there is some truth to that, I also think there's something of a permanent tolerance with meth. Combine that with the blurry glasses of nostalgia and it always seems like the dope of yesteryear was better.
