Any person licensed under this chapter who renders psychological services to a minor for problems associated with substance use is under no obligation to obtain the consent of the minor's parent or guardian or to inform the parent or guardian of such services. Nothing in this section may be construed so as to prohibit the licensed person rendering such services from informing the parent or guardian. For purposes of this section, "substance use" means the use of drugs or alcohol solely for their stimulant, depressant or hallucinogenic effect upon the higher functions of the central nervous system and not as a therapeutic agent recommended by a practitioner in the course of medical treatment.   [PL 2017, c. 407, Pt. A, §129 (AMD).]
