A long time ago on the forum I hang out with, I said something like "this is amazing, this is like heroin!" about whatever (not even a substance, probably something silly like a song or a video game). A guy who I knew as nothing but laid back and gracious scolded me in a way I remember to this day... not the exact words, but part of it was that he knew a couple who just handed off their new born baby for adoption to get their next shot. And I could tell there was a lot unsaid, too. Sorry for the tangent, but I guess, fuck heroin etc., and all the power to anyone struggling with it, things like it, or has loved ones or friends that do.
