PHILADELPHIA — It’s afternoon rush hour on Kensington Avenue and business is about to pick up for the half dozen or so prostitutes who are loitering across the street from the Huntingdon train station eyeing passing cars for potential clients.

Traffic has been light today and a few of the girls are already feeling the pangs of heroin withdrawal.

“I’ve been out here since morning and only had one trick so far,” a frail 30-year-old who would only give her initials, D.C., told The Daily Beast. “I barely made enough to get well.”
