(a) In this section, “governmental entity” means this state or an agency or political subdivision of this state.
(b) A governmental entity or an officer, employee, or agent of a governmental entity may not interfere with an eligible patient’s access to or use of an investigational stem cell treatment authorized under this subchapter unless the treatment uses an adult stem cell product that is considered an adulterated or misbranded drug under Chapter 431. For purposes of this subsection, a governmental entity may not consider the adult stem cell product to be an adulterated or misbranded drug solely on the basis that the United States Food and Drug Administration has not approved the adult stem cell product.
