Why does my heart beat speeds up when I'm hungry?

Help! I smoked K2 (synthetic weed) and now im having trouble breathing, rapid heart beat, chest pain....?

• Its Tuesday night. Sataday night i tried weed for the first time. The stuff i tried is called K2, its a sythetic herb thats dosent contain THC but is meant to manipulate its effects. I had one hit of the stuff and started halucinating on the couch for about an hour. After i started to come back to reality i noticed my heart was beating really fast. I was having a panic attack but i thought i was having a heart attack and was screaming for an ambulance. Eventually my friends calmed me down and walked me home. When i woke up the next day i felt a slight pain in my chest and noticed my heart was still beating fast. I went to the hospital wree they did all sorts of tests but said my heart was fine, and that i was just having an anxiety attack. I went home feeling a little bit better. However its been two days now. My heart beat can every now and then get really fast. I checked my pulse at 100beats per min sitting down. But seems to go to normalw ith movement. I still have a bit of chest pain on the upper left side of my chest, fairly high up. Im also having problems breathing, like i feel as if i am not getting enough oxygen when i breath. Im freaking out constantally thinking im going to die of a heart attack at any time. I searched the web and it says that K2 has caused ehart attacks, and has hospitalised many people (this i did not know when i smoked it). Problem is i live in a small town with a dogy hospital and no experts. Not even a ******* MRI machine. WHat should i do. Is this normal? Will the effects wear off? Im scared to go back to the hospital cause it might triugger anther anxiety panic and they will just right it off.

• Answer:

  Go back as many times as you feel comfortable. You may actually have something going on there that was upset by the weed you smoked. Now.... as far as smoking this synthetic drug..... DON'T! Now that you've had your first scare-i-sode with this mess and you know how's affecting you, don't do it again. It's equivalent to putting your mouth on the exhaust pipe of a MACK truck and sucking for an hour. Smoking itself is dumb but something laced with more unknown chemicals is just down right psychotic. Take care of yourself, dude.
