I was visiting my rentals last week; the sky was ugly with smoke, and everything was blanketed in ash.

Even in a small town I hear complaints of how some guy was smoking pot in the lobby of the ski lodge or hallway of the motel the school kids were staying at. 

It's not like you not paying a lot of money for this...That FHA buyer clearly is smoking something....that I might need to smoke as well each now and again!

Visitor’s pets are also not allowed.1.No smoking is allowed in dwellings.Any smoking in dwelling constitutes a violation of the lease agreement.TENANTS will lose full deposit.TENANT agrees to abide by the following set of RULES for residents of the premises:

I also stated that the building was now smoke free, along with some other things.

If they were able to enter through customs and get a stamp showing they are here legally I would probably accept that.However, I must say that in my limited (3 separate tenants) experience the biggest issue I had was one guy smoking on the premise when it was prohibited.

One of my units requested to terminate their lease early because of a neighbors cigarette smoke bothering them.

"you either smoke, or you get smoked....and you got smoked!!"

If that excuse came from an attorney they were blowing smoke. :) 

Little pills fit in your pocket so of course there gona grab some some munchies after they realize cvs stopped selling cigarettes....
