C.R.S. § 44-40-116

(1) It is unlawful for any person: (a) To sell a lottery ticket or share at a price greater than or less than that fixed by the commission; however, a lottery ticket or share that is offered at no additional charge in conjunction with the sale of a product or service shall not be deemed to violate this section unless the offer is made to a person under eighteen years of age; (b) To sell a lottery ticket or share unless authorized or licensed by the director to do so, but this shall not prevent lottery tickets or shares from being given as gifts; (c) To sell a lottery ticket or share to any person under eighteen years of age or for any person under eighteen years of age to purchase a lottery ticket or share, but this shall not prevent receipt of a lottery ticket or share given as a gift to a person under eighteen years of age; (d) To sell a lottery ticket or share at any place other than that place authorized and specified on the license.
