Was in the bathroom with a coworker and he recommended I try a juul, so I hit it. Took a pretty big drag probably about a 11-12 second drag, held the vapor in and I put my head to the wall and just fell and was laying in the corner for about 30 seconds. He took a picture of me (lol) and my eyes were completely open, but I don't remember anything, but I was blacked out. Was this just nic toxicity or was it something probably medical related. I probably should consult with a doctor, but I've never had this problem before.
