WATCH: National Geographic’s Doc About Drugs in Philly

National Geographic: “In Kensington, north Philadelphia, heroin, crack cocaine and PCP are dealt from a hundred different corners. Abandoned homes and factories serve as crash pads, shooting galleries, dope holes and stash houses. And for the fiends and dealers born in the neighborhoods, the area is a deadly trap. We’ll meet Jerome — an addict for more than 40 years — who sells clean needles, and Matthew, an HIV-positive user who tests heroin for local bosses.”
