As far as I know, Chris hasn’t done any drugs. In the State of Decay 2 video Adam mentions Chris hasn’t done any drugs except whippets (lol). Zach I’m pretty sure also hasn’t done any drugs. Adam references being high the most and Cory also is a druggie. Dave hasn’t directly mentioned it I don’t think but I could be wrong. Tomar smoked marijuana in the Hitman playthrough, but that was 6 years ago and I think he’s moved on to stealing heroin and fentanyl from homeless people.
