I got a couple of joints that my friend pre-rolled and I think somehow something got in them. I smoked about half of the joint which was only maybe a gram big, and I was either tripping or the highest I've ever been. I don't have that much experience with being 'too high' since i'm relatively new smoker but I don't think this was just weed. The main feeling I could describe it as would be that it felt like my body was moving in low frame-rate, Like my sensations were pulsing instead of constant. I felt just averagely high in my head but I felt fucked up in my body, at times it even felt like the pulsing physically hurt. I went to bed because at the time I was thought I had been laced. When I woke up and talked to another friend, a more experienced smoker, he said he'd never had that happen but he assumed that I was just 'too high'. So I trusted him but waited about a week to smoke the second joint, this time it was with a buddy and we smoked the whole thing together. About 15min after smoking the joint I started feeling the same sensations, I wasn't as paranoid this time though as I thought I was just smoking pretty strong weed or something. But I could tell my friend was visibly paranoid and he told me a bunch of times he thought he was too fucked up. This can't be all from a half a joint right? I'm typing this a day later and I still feel it a bit. If anyone has had any experiences like the one I described or knows what it could have been laced with let me know.
