i dunno does quality described as nugs count as hi-grade compared to amnesia haze? I know nugs doesn't help in description and i wish i had a stran name but the only thing i can tell you is when i smoked it it took less then one bowl to get me pretty high... not sure how this would compare to what i mentioned above or anyone elses high-grade... I usualy smoke pretty much and this still kinda did me in after 1 bowl... thanks for the help guys... I love this community
