The Ask, Listen, Learn video series and supplemental lesson plans have been designed to teach kids about the negative impact that alcohol and marijuana have on their developing brains, the consequences of underage drinking and underage marijuana use, and how to make healthy decisions. In this 9th installment, the curriculum focuses on adolescent mental health, positive and negative strategies for coping with mental health challenges, and how alcohol and marijuana can negatively impact the developing brain and mental health. Although this lesson is designed to be part of the existing series, educators may choose to use it as a stand-alone unit. Before getting started, be sure to read the Ask, Listen, Learn Mental Health Educator Guide and view the Ask, Listen, Learn Facilitator Guide.
