Jonathan Kirkpatrick & Kastalia Medrano

Jonathan covers harm reduction and re-entry. He’s incarcerated at Washington Corrections Center, where he’s a Teacher’s Assistant for re-entry workshops and trains peer educators in HIV and hepatitis C harm reduction. His writing has been published by the AppealTruthoutJewish Currents and the Seattle Journal of Social Justice. His Washington State Department of Corrections ID is #716850, and until WDOC corrects a 29-year-old paperwork error his name in Securus is “Jonathon.”


Kastalia is Filter‘s deputy editor. She previously worked at a number of other media outlets and wouldn’t recommend the drug coverage at any of them. When not at Filter, she works with drug users in NYC and drug checkers in North Carolina to track hyperlocal supply changes, and cohosts a national stimulant users call with Isaac Jackson.
