male / 27
smoker (marijuana and cigarettes 10 years)
The first time i had this problem I worked out intensley with weights, then immediately took 3 hits of a marijuana joint,. within a minute, my already fast heartbeat
went through the roof, then within 2 mins of that, I was left GASPING for air for hours, it was a very scary time i called ambulance and after a while i calmed down and breathing was ok enough for me to go home
This happened 3.
