So my buddy is in the hospital because he took a spill on his dirt bike. I went to go see him today and as usual i smoked a joint on the way. While i was there after about 25minutes, i was nicely high and then started to feel like i was going to pass out. I left the room and said i was going to step outside for a smoke but the feeling didnt go away. I could feel my self drifting pretty quickly. I went to go sit down, then the feeling went away for a minute, then returned and again i thought i was going to fall over and pass out so i sat down. I never did acually pass out , it went away after i went outside and got in my car.. Just wondering if anyones ever experienced a high that caused them to pass out or have a panic attack. I think thats what it mite have been. I didnt do anything unusal so im not sure what happened.
