Well, after I smoke (normally 1 or 2 days after) I get all spaced out. Like I can't concentrate on shit at all, my mind bobs of in the most random directions, and I sometimes lose my depth-perception when I'm standing in a group of friends (circle-style) and feel like their SO far away from me, but I'm standing not 2 feet away from them. It didn't do it after the first time I smoked recently (smoked some purp) but the last 3 or 4 times I've smoked, it's been from the same stash that I got from a guy. Like, you all know when you're high, your mind races and you just get loads of ideas, that feeling you have when you're high like that is the same one I'm having when I'm sober. Like everything around me feels so fucking vast that it's ridiculous. I basically go blank, and can't piece sentences together correctly in a conversation. This didn't happen after I smoked that purp (Or any other times I've smoked before, come to think of it.), but it happened after I smoked the same shit that I got from some other guy. I keep thinking it could be laced, but with what? It's beyond annoying, I can't concentrate on some of my task and it makes me so mad. Any idea what could be causing this?
