(410 ILCS 705/) Cannabis Regulation and Tax Act.
Section 10-20. Identification; False Identification; Penalty.
e) No agent or employee of the licensee shall be disciplined or discharged for selling or furnishing cannabis or cannabis products to a person under 21 years of age if the agent or employee demanded and was shown, before furnishing cannabis or cannabis products to a person under 21 years of age, adequate written evidence of age and identity of the person. This subsection (e) does not apply if the agent or employee accepted the written evidence knowing it to be false or fraudulent. Adequate written evidence of age and identity of the person is a document issued by a federal, State, county, or municipal government, or subdivision or agency thereof, including, but not limited to, a motor vehicle operator’s license, a registration certificate issued under the Military Selective Service Act, or an identification card issued to a member of the Armed Forces. Proof that the licensee or his or her employee or agent was shown and reasonably relied upon such written evidence in any transaction forbidden by this Section is an affirmative defense in any criminal prosecution therefor or to any proceedings for the suspension or revocation of any license based thereon.
