There has been odd bits of green around that hasnt been contaminated with this, and I always buy up as soon as I know where its at but over the last 2 or 3 months, its been constantly this gritty stuff. I know a few of people who retail LARGE amounts (bars, kielos+) and they all have the same, so you cant expect the small timers (oz and bars) to have any different stuff.
I blame it on the crack down. They should be cracking down on the hardcore drugs, not the drug that has no recorded deaths threw out the whole world. Seems kinda stupid if you ask me... but hey, thats the goverment for you!
