Addiction Across the Lifespan 1: The Impact of Substance Use on the Developing Adolescent Brain (2025-2026 Recording)-Addiction Across the Lifespan 1: The Impact of Substance Use on the Developing Adolescent Brain Recording

Video Transcription

Video Summary

The session focused on adolescent substance use and why it differs from adult use. Dr. Ken Zuha explained that teens and young adults are biologically more vulnerable because their brains are still developing, especially the prefrontal cortex, which controls judgment and impulse regulation. He used humor and familiar examples to emphasize that adolescents are more likely to seek novelty, take risks, and be influenced by peers, while also showing how early substance use can shape brain development and increase later addiction risk.<br /><br />He reviewed epidemiology showing that substance use, overdose risk, arrests, and depression are especially common in the 18–25 age range, and that most adults with substance use disorders began using before age 18. He highlighted how adverse childhood experiences, trauma, and epigenetic changes can increase long-term risks for addiction and other health problems.<br /><br />Dr. Zuha also described practical screening tools such as S2BI and CRAFT, stressing that asking “how often” rather than yes/no questions improves detection. He discussed treatment principles for adolescents: early access to care, harm reduction, family engagement when possible, respect for confidentiality, and the importance of motivational interviewing and stigma-free language. He reviewed treatment options for cannabis, nicotine, and opioid use disorders, including nicotine replacement, buprenorphine, and naltrexone, as well as the importance of naloxone access.<br /><br />The second half featured Natalie and her mother Alicia, who shared their lived experience. Natalie described starting vaping in middle school, progressing to opioids, multiple treatment attempts, relapse, and eventual sustained recovery with medication, AA, and support. Alicia emphasized how nonjudgmental communication, family involvement, and naloxone saved Natalie’s life and supported recovery.
