Volunteers are counting piles of used needles dumped out of plastic bags on a hot Saturday afternoon. People are lining up under a shade tent on a secluded north Fresno street to get rid of their dirty syringes. In return, they're getting an equal number of clean needles from the volunteers at the Fresno Needle Exchange Program.
The first person in line is a woman in her late forties who prefers to be called Tobi. She's a heroin user who's been coming to the exchange for 10 years. She's seen other drug users trading their old needles on the streets.
