These sort of stories remind me of how utterly misguided people are who support legalized recreational marijuana use.
There is an insurance company in Iowa that refused to hire a person unless they agreed that they would not drink or smoke. Why because one of their primary classes of insureds were churches. I am not certain if that rule still applies there?
The ban on smoking and smokers at hospitals makes sense. I expect that once the new rules settle in on new employees further attention will be directed at current employees and done carefully to avoid discrimination suits.
I found it quite a paradox when at a hospital in Minneapolis you would see medical personnel outside smoking with lung cancer patients
