Was this weed laced?

The other day a friend and I smoked some weed. I’m not sure if I just had a bad reaction to the stuff, or if it was laced with something. When I took the hits, it burned my throat a lot more than it should have, and after about 10 hits I had to stop. I started to feel really dizzy and light-headed and slightly nauseous. My friend told me to sit down and got me some water. I sat with my head between my legs to stop the dizzyness and nausea, but it didn’t seem to work. When I looked up I couldn’t focus on anything and my eyes kept darting around. My body started to feel tingly, and almost numb and everything looked like it was taken in snapshots. I couldn’t see fluid motions, everything looked like it was a bunch of pictures being put back-to-back. My heart started to beat fast and I started to sweat. I told my friend that I didn’t like this at all, and I started freaking out a little. It started to feel like someone was snapping hundreds of rubber bands all over my skin, and I couldn’t stop it. I felt really anxious and restless, but at the same time sort of relaxed. We put the tv on and I tried to focus on the picture. It only lasted about 2 hours and went away, but the exactly 12 hours later it happened again, but not nearly as bad. Was this just some really good weed, was it laced or did I just have a bad reaction to it?
