I'm sorry this upsets you but I feel it's a good idea to ban smoking in any hospital atmosphere since hospitals are to help and heal people. The other patients in the hospital may not want to have to inhale the gases sent off from 2nd hand smoke because they not only stink but are a real health concern since any amount of 2nd hand smoke inhaled passively is dangerous to the people breathing them in.
I think all mentally ill patients in hospitals should be encouraged to quit and what a better time than when in a facility that is there to help you with your mental health. Since quitting smoking will bring out a lot of strong emotions the patients quitting will have someone immediately on hand to listen and understand.
I think this is a super good idea. I'm glad to hear it. Again, sorry if this upsets you.
