I have been smoking for a month. Earlier this week I was sitting in the hot tub with 2 friends. It was a cold night and it was snowing. We passed around a blunt and each time it came to me I felt increasingly weaker. At first I thought I was really high then my head started spinning. I told my friends that I was going to throw up and they thought I was joking. I then almost passed out for a minute but they kept me awake. They helped me walk inside and sit on the couch. I then began to feel throbbing throughout my entire body and my chest was pounding. It was the first time I had ever experienced this. To make a long story short I did go to the ER after I threw up and I couldn't control myself. I got over it in a few hours and calmed down. The doctor was convinced that I was an electrical occurrence in my heart that caused it from sitting in the hot tub in cold weather and having caffeine. But it was the worst experience of my life and an embarrassing one because my friends parents had to baby sit me and I threw up.

Was this a panic attack induced from smoking weed?
