Deliveries are limited to one per day, limited to private residences, and may not be made to college campuses. The act provides protection against criminal prosecution for those making the deliveries. Delivery is only allowed in a jurisdiction if that jurisdiction has voted to allow delivery either by referendum or by the governing board of the jurisdiction. Medical marijuana delivery permitting for medical marijuana centers begins on January 2, 2020, and medical marijuana delivery permitting for medical marijuana transporters, and all retail marijuana delivery permitting, begins on January 2, 2021.
