I think it's this fake weed they sell at bodegas called K2. It's fake weed sprayed with some crazy research chemicals that make people into zombies. K2 is illegal in NYC, but the cops do nothing about it. It also doesn't come up on most drug tests because it's a new chemical. People on parole and probation use it, and the homeless population. Those homeless people live in shelters and qualify for free apartments after 90 days.
