In most cases, adolescents should be informed of a decision to disclose substance use to their parents. Inviting adolescents to discuss how this will be done, including if the adolescent will be present, and whether you or the adolescent will disclose the use can be an opportunity to discuss their concerns. You should seek to understand if an adolescent has specific fears related to such a disclosure including careful consideration of any history of domestic violence or abuse.
Although adolescents increasingly identify with the opinions and values of their peers, it is a mistake to assume that they therefore do not value the opinions of their parents and the concerned adults in their lives. Parents play an integral role in preventing and treating adolescent substance use disorders. Except in rare instances of severe parent-child relationship problems or abuse, parents can and should be engaged as invaluable participants
Dr. Peter R. Jackson
Being aware of the legal and ethical obligations in treatment of adolescents presenting with any level of substance use, you can improve outcomes by thoughtfully inviting the participation of parents and other concerned adults into the prevention, screening, and treatment of adolescent substance use disorders.
