I always was convinced that the browner the dope in solution, the stronger it is. Indeed that has been my experience for the majority of times, however I've more recently discovered examples which completely contradict this. I've had guys who have sold me shit so brown that I had trouble registering, and it was just barely passable, and also had this group of Asians have this supposed special source which was according to them, nearly pure. I was a bit upset after I bought it and saw that it barely had any tint whatsoever when mixed with water. Let's just say that it's a damn good thing that I have a policy of shooting just the smallest possible amount whenever I have a new source or product. It hit me so hard, I was literally reeling - huge rush, vastly overpowering almost everything else I've had for the past 6 years. Color is useful as a general guideline at times, but certainly not always.
Not only that, but keep in mind that 100% pure heroin like most purified alkaloids, is a white, odorless solid. When pure, properly processed heroin is mixed with water, it should look like nothing more than water. I'm pretty sure that the brown tinge comes from black tar being diluted to various weaknesses with white fillers, since black and impurity mixed in that's white would tend to produce a brownish powder. I think China White - the best and most pure form you can get - isn't brown at all. But here in BC, almost every bag/flap I've ever purchased has cooked up to be a varying shade of brown which leads me to believe I've only had black tar, possibly never even trying CW. I really would love to though, even though I've been clean over a year now, on MMT. It would still be very tempting, even though I have basically no more cravings, simply because it was such an unknown rarity that was so sought after. I'd like to know what a really strong, pure H rush is like.
