Something exactly like this happened to me a couple days ago and it drove me crazy because I kept calling my friends to make sure I wasn't dead or anything. Everyone told me they didn't feel as much of the effects as I did, but most people said I just got really high because it was my 1st time smoking in months and I'm a novice to begin with but I was scared it was laced but didn't think it could be at the same time because one of my good friends was the person who I got it from and he's had the same source for over a year. I guess it goes hand in hand but did you also feel like you had no concept of time IE everything took way longer than it should have? I remember waiting at a traffic light (god knows i shouldn't have been driving that night but i had a friend kind of watching over me) and it felt like hours for it to turn green so I just ran it... that didn't please my friend in shotgun...
