What happen is that I was drinking for 3 hours and i only took 2 or 3 puffs of weed (my first time). I start to get sick and i ran to throw up and then my chest start to hurt and i start to have hard time breathing and felt like my chest hurt so bad to where the point i was gonna die. I never ever felt like this before. Why did my chest hurt so bad? Was it heart attack or something? I am only 20 years (almost 21).
