Would this be helpful in either:Getting them to stop smoking? 

I am considering buying the property in cash then hiring Servpro to fix the cigarette damage.

I used to use Noiseware but Minut monitors for smoking as well.

City recently did a building inspection and we noticed the tenant is smoking in the unit (cigarettes and marijuana), food waste everywhere leading to building pest issues, and there are 5 people living there now (3 adults and 2 kids).

Always meet in person:  This will give you a good idea of the person, if they're smoking a cigarette while talking to you, or being very negative about their previous landlord make sure you make note of that.4.)

We have tenants that looked good on the application and background check that when they showed up with pet in tow (no pets allowed), 10 relatives and vehicle filled with trash and cigarettes in everyone's pockets that we knew this would be a problem lease. 

As for the smoking, after some back and forth, I ended up taking a slightly larger chunk out of the deposit to cover deep cleaning and the replacement of the carpet, which was saturated with smoke smell.

(Ok I get it that its 2024 and people smoke weed).
