About 3 years ago, I smoked Spice and ended up almost having a heart attack. I had already smoked it for about two years prior, and one day I just got ahold of another strand of spice and smoked it and my heart beat incredibly fast and my chest was rising. I thought I was going to die. Months later, I went to the hospital about 10 different times with a random racing or very sore heart. Also, My arm left arm would get numb along with left side of neck. I did try spice one more time, shortly after the first incident, and it did the same thing again. After exiting the military, I smoked a little weed for about a month and felt fine. One day, I decided to smoke some weed, and I got the same pain and felt like I was going to die again and even called an ambulance. I now get heart pain anytime im even around weed, but I stopped smoking 100%. Is there any tips or reason for this? Whn going to the hospital a few times, they did say I have a sinus arythmia and I even wore a heart monitor for 3 weeks and the worst they saw was a close to 3 second pause. Any feedback would be great, thank you.
