ive been having trouble on my smoking technique since i first tried the spice almost a year ago. ive been trying different methods ever since. my first breakthrough was a one hitter on a class pipe, it was the biggest explosion ever. never has it been the same again. im extracting fully transparent crystals, and the last time i evaped on a glass pipe, although i burned it as best as i could, no smell came out of it at all and i could see the vaporization going smoothly. after i had finished inhaling, i exhaled nothing came to me, and so i sat up straight and a terrible pain struck the back part of my head. i felt as if my visual cortex was on fire! the pain lasted a couple of minutes with the same intensity and went down from there until i felt asleep. i need to know, will i ever have an experience as intense as the first one? is there anyway the product im extracting has an inferior quality? please help>
