Yes. I smoked some weed in my early 20s. It was a shared joint that had been laced with something. The others didn't tell me it had something else in it. They were more seasoned and used to taking all kinds of stuff so it didn't seem bad for them. I lost consciousness and hit the floor. I still don't know what else was in it. I rarely smoked weed and it was the only thing, apart from whatever was in that joint the one time, that I've tried.
Have you ever gone to the hospital in an emergency?
