Tennessee Code Title 63. Professions of the Healing Arts § 63-10-223

(a) The general assembly finds that patient access to information about controlled substances is crucial to combating the deadly opioid epidemic in this state and that any obstacle to patients' receiving information about controlled substances is a serious threat to public health.

(b) Any agreement purporting to limit the ability of a pharmacist to discuss any issue related to the dispensing of a controlled substance with a patient is contrary to the public policy of this state and is void and unenforceable. This includes, but is not limited to, information about the risks, effects, and characteristics of the controlled substance; what to expect when taking the controlled substance and how the controlled substance should be used; reasonable alternatives to the prescribed controlled substance; and any applicable cost sharing for a controlled substance or any amount an individual would pay for a controlled substance if that individual were paying cash.
