ice is nearly pure, over 80% i think, crystal is midgrade, and crank is the bottom of the barrel, at least here in the bay.
regardless, that shit is some of the most evil crap to ever be sold on the streets just as if not more-so than crack. i personally saw my aunt addicted to that shit and the way it ruined her life, the way my two cousins were basically abandoned, the physical changes she went through. its sad really.
i have a personal grudge against that shit i wouldent touch it with a 10 foot pole
and fdd, i really hope you dont use that stuff man
