Today, my friend and I got together to smoke a blunt like we do most days. Got there after having woken up a half an hour prior and he began to roll a blunt with just normal mids (mids are all we got here in my small town) and some roach weed from 3-4 joint roaches mixed in. Progressing to the point where I start to get less high with more weed (Fairly new to cannabis culture and such, ye), I intentionally took bigger hits off the blunt than I'm used to. Not to the point where I was coughing with every hit, but still definitely bigger hits. Just as I take my 5th or 6th hit, I hand it back to him and go lay down because I started to feel it. A few minutes later, I wanted a cigarette, so I went to get up, but as I stood up, my vision started to get spotty and I felt nauseous and hella dizzy. I fall back onto his bed, thinking that maybe the weed was laced with something and I picked the wrong time to start trying to take bigger hits. My vision goes black for a second and I don't remember anything he was saying to me, but I know he was trying to talk to me. It takes me about 10 minutes to recuperate, but I'm still baffled as to what happened. I don't think it was laced with anything, as my friend didn't react to it any differently than he normally does. Could I have just been dehydrated? Was it the roach weed in there (that I forgot about while I was hitting it), or was it just the fact that that's probably the highest I've ever been? I didn't feel much more high than I usually do, so I'm kinda just wondering if this happened to other people too. It was actually a pretty scary experience tbh but I don't think it's turned me off smoking pot. Maybe that's just my limit? Idk.
