Adolescent use of electronic cigarettes (vaping) remains steady. Teenagers can easily recite the health risks of cigarette smoking, however, awareness of the risks of vaping and the impact of nicotine on development is variable. This 90-minute webinar will explore how adolescent brain development is altered by nicotine or co-use of nicotine and cannabis. We invite educators, mental health and substance use professionals, and family members to join us in learning about the possible consequences of adolescent vaping.
