It's all unjustified to you until you actually have someone who steals to support their drug addiction, threatens coworkers, commits violence, or worse. So many people here seem to love the idea that drug users are these innocent people wrong by society, but it's usually because they are already insulated from them in their workplaces.
All it takes is someone high behind the wheels of a forklift to understand why these policies are in place, or someone in charge of industrial machinery showing up drunk or stoned or worse. Or a nurse who essentially robs the hospital blind to feed an addiction.
The point I was calling for was to start using some degree of common sense vs blanket "zero tolerance" policies wrt hiring.
Someone who was let out of prison 3 days ago with a record of violent/armed robbery is very likely not the same sort of potential problem as someone who did 6 months in prison 23 years ago for possession of marijuana.
