Ive smoked weed for years. but recently I smoked this stuff and the next week after i felt dizzy, lightheaded, just really uncomfortable. It has never happened before. So i stopped for a week or so or until i felt better, then once i felt better again. i took 4 rips, and the next day i started feeling shitty again. I bought my sack from the same guy both times. Could it be the chemicals he is using that i am smoking thats making me feel dizzy or what? is it laced?
