I've had China white heroin that was almost the color of sawdust, and I've had China white heroin that was almost the color of Afghan black tar heroin. And then a few times I got lucky with a great deal on some China white heroin that was really China white. They were all heroin ( and only god knows what else). I learned earlier that the fentanyl patches I was drying the gel out of, powderize, then snort, is what everyone is referring to with the heroin epidemic. I was snorting the tiniest bit of a line. And I was by far the highest I've ever been off that stuff. I hope he doesn't have his hands on some H cut with a patch. But honestly the combo if I'm remembering right of powder H and powderized fentanyl gel, would make a grey concrete dust powder look. I hope that's not what he has been doing. Earlier @True concern and I were talking about the same thing and I told him I was to scared to shoot it. I only snorted it, he told me that's what is killing so many, shooting fentanyl patches gel. Dang I honestly thought that was something me and a few of the most stupid junkies were doing. I didn't know it was being done nationwide. Anyway whichever way you look at it, he's right it is heroin and even if he did know for a fact it was cut with this or that, there's no way for him to know what else is in it. But listen to this close, my mom had damp hands just slightly and she got my Suboxone for me and a guess some absorbed through her skin because she can't take pain meds at all and we had to take her to the er. She's ok but her blood confirmed buprenorphine. So don't go touching the stuff. I would just leave it covered. I would suggest to just stay nieve about heroin. Nothing good comes from it. And if your not using it then I would just ignore it. Since . Have some clean time and am really seeing how destructive I was being and how wrecklessly I was living, it has made me fearful of those things that I told people I had to have to live. I'm scared of heroin too now. And I don't want to educate a recovering addict on the ins and outs of a new drug. 1. BecauseI want to protect you and everyone else from it. And 2. Thinking about it brings back bad memories for me. C, I really am praying that he sees the error of his ways while he still has his life to be able to see with. And for you that you continue on your journey of healing. Remember that you told me we can only change us God bless.
