(1) Any person whom a peace officer or enforcement officer has reasonable grounds to believe is under 18 years of age who purchases or attempts to purchase, or attempts to obtain or obtains tobacco products may be detained for a reasonable period of time and in such a reasonable manner as is necessary to determine the person's true identity and date of birth. A person under 18 years of age who is cited for attempting to purchase or purchasing tobacco products is subject to a fine as set by chapter 7.80 RCW or participation in a smoking cessation program or both. This provision does not apply to a person under the age of 18 who, with parental authorization, is participating in a controlled purchase as a part of a liquor and cannabis board, law enforcement, or local health department activity.

(2) Tobacco products possessed by persons under the age of 18 years are considered contraband and may be seized by an enforcement officer as defined in RCW 7.80.040.
