MARIJUANA use in rental in IL

[Nolan Mahoney]

Hello, 

Since marijuana is recreational in IL im a little perplexed on how i should go about it in my rental. Since its legalized i cant ban the use of it onmy property right? Also in the lease agreement i have a no smoking policy because i dont want anyine smoking anything inside the unit. Are my hands tied here because marijuana is legal now? can i at least put in the lease that smoking can be done outside the unit with an ash tray and all ashes, butts must be thrown in an ash tray after use?
