Upcoming Legislative Spotlight: Illinois HB 4306
A major regulatory update arrives under House Bill 4306, effective July 1, 2026. This legislation formally amends the Use Tax Act and the Retailers' Occupation Tax Act to legally classify medical cannabis under the definition of "prescription and nonprescription medicines and drugs." This permanent designation permanently secures the 1% tax cap for cardholders, separating medical treatment from the commercial adult-use market.
