I have known a lot of people with hep c, all the older junkies from generations prior to mine had it it seemed, I used to have junkie roommates which ended very predictably, with them stealing my shit and selling it for pennies on the dollar. But some of their junkie acquaintances were ok, they were like in their 50's and still doing fine, they just couldn't drink much if at all and idk what else. Opiates for all of their faults don't harm any organ systems.
