The game pieces can be a beer can ,a syringe ,and cigarette  

I don't rent to smokers. 

When you applied, did he ask if you were a smoker and if so, what did you answer? 

If the wipe shows the yellow tinge of cigarette tar, you have a problem.

Cigarettes? 

Lets weed out the real dead beats and drug test them when they rush to the ER, or to get their unemployment check, ETC.I am all for helping the mother that has been abandoned by a dead beat with kids; so long as I don't have to support her cigarettes, booze, or other sins against humanity.

I also look inside their cars to see if they are messy or smoke cigarettes.

From my understanding you are required to accepted it, however verify your local laws. the only way around this is if they don't fit your screening criteria. so if across the board you don't accept smokers or anything else along those lines that are not a protected class you can deny the tenant.

And oh by the way, it stinks to high heaven of cigarettes.  

“the lease says ‘no smoking’ you just mean cigarettes right?”
