I actually was talking to a neighbor at my apartments 20 some-odd years ago. We got to talking about coke and he asked if I’d ever smoked it before.
“No…” So I followed him across the hall to his apartment and took a hit. “Whoa, this is fucking great! …Wait, when you smoke it isn’t it crack?”
“Yeah, it’s awesome isn’t it!? You know, if you want more I can probably find some…”
So, yup. I got my first hit of crack for free. I never thought that happened in real life before, either, and I’ve never had or heard of it happening since. Additionally, about six months later I stopped smoking crack.
