On December 4, 2019, Governor Pritzker of Illinois signed Senate Bill 1557 (SB 1557, or the Bill), amending existing marijuana laws in the state. As of January 1, 2020, recreational marijuana sales will be permitted in Illinois, passed in June 2019 via the Cannabis Regulation and Tax Act (the Law). SB 1557 amends the Law in many regards, but of specific note has some amendments to workplace provisions that prove illuminating for employers. Although the Bill is effective immediately, it will not have a real impact until the Law goes into effect on January 1, 2020.
