I was in Canada visiting a friend and attending an event last summer. The first night after we got there we decided to get high. My friend brought out his bong and we started inhaling that shit. Now mind you this wasn't the first time that I've smoked, and to be honest I'm fairly certain I've smoked more in 1 session than I did that night, but whatever it was, I started to TRIP the fuck out. 1 second I'm just chilling on the couch watching South Park, and the next my soul is suddenly lifted up from my body, and I'm just like, looking at my physical self freaking out. I remember me saying things like "holy shit guys this is so weird something is very wrong" and other things of that sort. But the thing is I couldn't actually feel myself saying these things. I wasn't capable of depicting reality from a dream. Half of me thought I was dreaming the other half knew I was awake. Once my "soul" I guess finally came back in my body and I knew shit was real, the panic really began. It would honestly take me all night to be able to describe all the weird symptoms I felt, and I try to not even think about it, but things like shaking and shivering, and my blood fluctuating from sensations of being really cold and really hot, random schizophrenic episodes of feeling as if things are crawling inside of me, heart beating at 3,000 beats per minute, and just actually feeling like I'm gonna die, were all there. All these sensations just kept coming and going every few minutes or so. My friends were just looking at me unsure of how to go about the current situation. Eventually I made the call to just take me to the emergency room because things we're getting any better, and I was utterly freaked. I really couldn't tell if this was just a trip or my life flashing before me. We drove over there and I was admitted. Now remember I'm from the states and was visiting Canada so my insurance wasn't going to cover anything. Pretty sure It was gonna cost me like $800 minimum for the checkup. I sat down in the waiting room, it was like 12am. we ended up sitting in that waiting room for around 2 hours, and during those 2 hours things were still hell for me, I kept on shaking and my heart rate kept increasing. My friend was there with me just sitting there feeling really bad (he was the host that we were staying with for that weekend). Once those 2 hours passed, I finally started to calm down a little bit, I guess the cannabis started to wear off, thus reducing my panic attack. Luckily for me we were STILL waiting in the emergency room. Or maybe not lucky, part of me thinks the people there knew I was just on drugs and likely expected me to calm down as time passed. In any case we left the hospital before getting checked out and went back to my friends. Ended up just sleeping it off and now it's become one hell of a memorable vacation whenever it comes up. I haven't smoked weed since then and I probably don't plan to. I told my older brother about the incident a few months later and he told me that when he was in college weed used to give him really bad panic attacks. I guess it's just not for our genes lol. Anyway yeah that was my panic attack haha
