Hey Nolan, I couldn't find recent information disagreeing with the information I included below. But, maybe this would be a good question for a real estate attorney in your area?
According to this article I found on Chicagoland Apartment Association, posted on October 2, 2019, "Nothing in the new law says that landlords are required to allow tenants or visitors to use cannabis or cannabis products on or in their property."

Also, on July 15, 2021, Governor JB Pritzker signed HB 1443, amending Cannabis regulation. This article that outlines the Cannabis Regulation and Tax Act explains, "The Act applies the restrictions of the Smoke Free Illinois Act on smoking cannabis, and provides that property owners may prohibit the use of cannabis by any guest, lessee, customer or visitor. In addition, lessors may prohibit cultivation of cannabis by their lessees."

I hope this helps!
