Up until recently for about two months I was using around 2 bags of heroin per day, snorted. The heroin was extremely pure, and within about 8 hours of last using, I would start to get withdrawal symptoms. When I ran out of dope I used suboxone and the withdrawal symptoms went away within a few hours. A day after using the sub, I bought a bundle of heroin from a different dealer, and this turned out to be really shitty dope. I would need to take down a few bags at once just to get a buzz. Oddly though, even though I have used this heroin a lot less frequently than the purer heroin, I never seem to get any withdrawals from not using it. I'm not sure if there's any reasoning to this, or just that since the heroin isn't as good, maybe my body doesn't miss it as much and thus doesn't go into withdrawal? I know that sounds really stupid, but I'm not sure what else it could be. Any answers to this would be appreciated, thank you.
