That's an interesting question. If someone had a smoker running all day, everyday, and it was an annoyance to neighbors - yes, I think there should be recourse.

One person shouldn't be allowed to harm other people's enjoyment of their property.

As someone who was vegan/vegetarian for many years, the smell of bbq used to make me ill. (I only eat meat now).

Only a self absorbed busybody loser jerk with nothing better to do would complain about the neighbors bbq'ing. 'get a life'.
