R.I. Gen. Laws § 21-28.11-25: Contracts pertaining to cannabis enforceable.

It is the public policy of the state that contracts related to the operation of cannabis establishments under this chapter shall be enforceable. A contract entered into by a licensee or its agents as permitted pursuant to a valid license issued by the commission, or by those who allow property to be used by a licensee or its agents as permitted pursuant to a valid license issued by the commission, shall not be unenforceable or void exclusively because the actions or conduct permitted pursuant to the license is prohibited by federal law.
