So here's my story, 23 yr female. I've smoked weed for about 4 years, cigarettes for 3 (currently working on quitting for obvious reasons.
Never had severe problems with weed until this past January. Hit the bong pretty hard and about 30 min later I was on the floor. My chest had severe pressure, my muscles had spasms, I couldn't even speak to my friends hardly to tell them what was happening. Landed in the ER that night with tachycardia (heart rate was 160+ bpm)
no problems again until about a month ago, same thing, same terrified feeling. I was alone this time so I made myself pass out after about 2 hours.
And it happened again last night. I ate an edible at about 10 pm, it hit at 11, by 11:30 I was thrashing with pain. It's 7 pm the next day and I still feel awful, but not like I'm going to die as much as I did initially.
It really sucks because I never considered I'd have to stop smoking, but after seeing all this, it might be the only answer. I've been to the doctor since and my labs were fine, but of course I hadn't smoked when I took the blood test so it wasn't happening then.
