I’ve been noticing beginner abscesses after I moved and started getting my stuff from a different guy. And I’m not even sure what it is, cause it doesn’t seem like black tar. Although it looks like it and kinda smells like it. But it fails the test I use to determine the strength of a shot I’m gonna do, I will put a small drop on on my tongue and the more bitter it is the stronger it is. But the stuff down here doesn’t have a bitter taste at all and Dosnt smell like regular heroin. It also has a very hard to being smoked on foil, It just won’t slide down.
