RIP DAVE PURCHASE
Purchase was a needle exchange pioneer, setting up a TV tray and fold out chair on a street corner next to a heroin spot and handing out clean needles at the height of the AIDS epidemic, on the front line of harm reduction. I work a lot with addicts and ex-addicts who may not be alive if it weren't for this guy. Thanks, Dave. If you want to read more, here's his obit.
