So I am (or was) a regular marijuana smoker. I have never had any problems with smoking, however I started taking legal over the counter herbs. I had been doing it some time until one incident sent me to the hospital. My heart skyrocketed to 180 over 90. It was very serious and yes I will never smoke over the counter ever again. I have recently tried smoking marijuana, but only small amounts. Everytime though I would notice this pain in my chest. It couldn't have been my heart as it was fine. The most recent I started to have a pain right below my lower left rib. It wasn't excrutiating, I wasn't having a panic attack and my heart was fine. However there is now a small knot on my lower left rib. It doesn't hurt anymore, sometimes it is sore and I can easily ignore it, most of the time I don't even notice it. I'm not sure it has any connection with my incident, but since it only happened after it I can assume the previous data will help. I hope it's not too serious or that I have to stop smoking altogether.
