Wintertime shots of heroin users and dealers using and being arrested. Crack users smoke crack and inject into their veins with needles and syringes. African-American woman smoking a pipe. Cooking heroin on a spoon. Injecting into hand and arms. Both men and women shooting up. Group of people, dealers, users, are lines up against wall and along a fence, are patted down, and some are handcuffed and arrested. Looks like the projects in New York City, possibly East Village.
