It was about the 10th time I was smoking and we started smoking the first joint. I am not really resistant and was instantly high. We went to a restaurent and my friend kept begging to go smoke the second joint. We decided to go smoke it and I took about 3 puffs of it and then it hit me really hard. I closed my eyes for maybe 10 seconds but it felt like hours and when I opened them I couldn't remember what I was doing or where I was. I was looking around and was really lost. It took me about 2 min to remember what I was doing and when my friends finished we went back to the restaurent.Everything felt so weird, at first everything I was doing would happen 5 seconds later. If I said something my mouth would say it 5 seconds after and it felt as I wasn't talking and was watching myself instead. Time was passing way slower than normal, my vision was focussing on anything and was blurred at times, I couldn't remember what I said 5 seconds earlier and I had tics that I couldn't control. for example my head would look at the same place at intervals of 10 seconds and I would always say the same phrase. When I told one of my friends the experience he told me the weed wasn't probably synthetic or something else was in the joint. I would like to ask you why do you think these symptoms happened to me while high?
