i smoked weed on may 17th, 2008 and i had the scare of my life. I was so high but that was not the thing all of a sudden my head started to feel as if something was trying to get out of my brain and as though some liquid was pouring out of my brain seriously. I then couldnt breathe and i felt as though all the air was being takien away from me. This feeling occired twice. To this day now i feel sensations through my head and my necks muscles and bacl muscles start to become tense and i feel as though my head is poping and crumbling. IS this a ide effect bareing in mind the last time i smoked was may 17th.
