Illinois Statutes Chapter 410. Public Health § 705/10-15. Persons under 21 years of age

(a) Nothing in this Act is intended to permit the transfer of cannabis, with or without remuneration, to a person under 21 years of age, or to allow a person under 21 years of age to purchase, possess, use, process, transport, grow, or consume cannabis except where authorized by the Compassionate Use of Medical Cannabis Program Act or by the Community College Cannabis Vocational Pilot Program.

(b) Notwithstanding any other provisions of law authorizing the possession of medical cannabis, nothing in this Act authorizes a person who is under 21 years of age to possess cannabis. A person under 21 years of age with cannabis in his or her possession is guilty of a civil law violation as outlined in paragraph (a) of Section 4 of the Cannabis Control Act.

(c) If the person under the age of 21 was in a motor vehicle at the time of the offense, the Secretary of State may suspend or revoke the driving privileges of any person for a violation of this Section under Section 6-206 of the Illinois Vehicle Code and the rules adopted under it.

(d) It is unlawful for any parent or guardian to knowingly permit his or her residence, any other private property under his or her control, or any vehicle, conveyance, or watercraft under his or her control to be used by an invitee of the parent's child or the guardian's ward, if the invitee is under the age of 21, in a manner that constitutes a violation of this Section. A parent or guardian is deemed to have knowingly permitted his or her residence, any other private property under his or her control, or any vehicle, conveyance, or watercraft under his or her control to be used in violation of this Section if he or she knowingly authorizes or permits consumption of cannabis by underage invitees. Any person who violates this subsection (d) is guilty of a Class A misdemeanor and the person's sentence shall include, but shall not be limited to, a fine of not less than $500. If a violation of this subsection (d) directly or indirectly results in great bodily harm or death to any person, the person violating this subsection is guilty of a Class 4 felony. In this subsection (d), where the residence or other property has an owner and a tenant or lessee, the trier of fact may infer that the residence or other property is occupied only by the tenant or lessee.
