It smells terribly, exposes others to negative health effects without consent and is one of the biggest causes of littering. Simply put it is a major nuisance with no benefits apart from profits for the tobacco/drug industry and addicts getting their high.
Could probably extend that to anywhere around minors in general too.
I was a smoker for years and what made me quit was when I really grasped how much it makes you reek.
I have staff who take smoke breaks and god lord you can smell that nasty shit the moment they walk back on the floor.
it isn’t practical to ban smoking in public places but all Campus work sites should have designated smoking areas.
