(a) It is the intent of the General Assembly that, in order to ensure a uniform, statewide solution, on and after the effective date of this Act no unit of local government shall mandate that a new drug take-back or disposal program be created and no expansion or change of an existing program or program requirement by a unit of local government shall occur that is inconsistent with this Act.

(b) A home rule municipality may not regulate drug take-back programs in a manner inconsistent with the regulation by the State of drug take-back programs under this Act. This Section is a limitation under subsection (i) of Section 6 of Article VII of the Illinois Constitution on the concurrent exercise by home rule units of powers and functions exercised by the State.
