I've been a user for 27 years, and I've been on the east coast and use the what is called China White back in the day about 27 years ago, East Coast is where I started. As far as gray I don't know what you mean by that if you mean like that kind of gunpowder stuff it's kind of powdery and brownish blond, that is just another form of brown tar. And then there's just a straight kind of black brown deep brown tar on the west coast here in Seattle. This stuff the brown stuff in the Seattle in the old days I would say you be very hard-pressed to OD with west coast Brown, what I mean by that is once you're experienced user one would have to prep for five really heavy dose thick needles and back-to-back lay them all in and you might OD. However with the world as it is today and the Fentanyl and everything I wouldn't say that any longer. With that said and not said I finally ran into my first batch of fentanyl laced Brown a month ago it may be nauseous and sick pokey. So I flushed it and went and got some more from someone else and dad had it too. I'll tell you heroin has served me well in the 27 years I've never had a problem with it except for when I'm out, however I must say that the geopolitical climate that it is and the state of which folks are finding it necessary for whatever reason to put Fentanyl in every gosh darn thing even going to find it in our milk before we know it, it seems to be infiltrating everything. this time in history is not a good time to become a friend of heroin or any opiate for that matter. I would say try to find a new drug of choice, if I could only give good advice and that would be again this is just a bad time in history to be liking heroin, on many fronts for many reasons I think it has run its course in history and it will never be like it was of course so please avoid it it's just not any good out there anymore even if someone wanted to take you under their wing they couldn't do so reliably because I'm not sure they could get a proper clean batch and then guarantee you a continuous run of something clean and suitable.
I would say the 50s and the 60s were probably the best time in American history to be a friend of heroin.
