I think you’re missing the boat here. The kids and young adults are in a specific job training program, not to get trashed but to learn. Furthermore, lots of programs (private and public) have substance free requirements. Anyways, requiring people to not come home trashed is by no means puritanical. They didn’t say you have to be completely sober and join a teetotaler society they just said “ don’t get visibly intoxicated.”
