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.
Had someone similar at my office, I had to ask her to stop at least spraying herself on the row because it was giving me and another headaches.
She did oblige to her credit
