It is the public policy of the commonwealth that contracts related to the operation of marijuana 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.
