i dont know but it sure does taste like something i picked out of my shit. i smoked nothin but dirty ass shwag this weekend and i never will again(if i dont have to) The highs suck(one joint is all i smoked at a time)for me atleast. Its like with the shitty weed u cant reach that amazing out of ur head high that we all love.And smoking a lot of it sucks anway.Brown as fuck.
