R.I. Gen. Laws § 21-28-3.26: Labeling by manufacturers and wholesalers.

Whenever a manufacturer sells a controlled substance in packages designed for sale at retail and whenever a wholesaler sells or distributes a controlled substance in a package prepared by him or her, the manufacturer shall securely affix to each individual package in which that controlled substance is contained a label showing in legible English the name and address of the vendor and the quantity, kind, and form of controlled substance contained in it. No person, except an apothecary for the purpose of filling a prescription under this chapter, shall alter, deface, or remove any label so affixed.
