Dr. Bonnie Halpern-Felsher: Vaping, Alcohol Use & Other Risky Youth Behaviors

In a compelling episode of the Huberman Lab podcast, Dr. Andrew Huberman hosts Dr. Bonnie Halpern-Felsher, a developmental psychologist and professor of Pediatrics and Adolescent Medicine at Stanford University. Their discussion provides deep insights into youth risk behaviors, including vaping, alcohol use, and other dangerous activities prevalent among adolescents and young adults.

Vaping: A Gateway to Nicotine Addiction

Dr. Halpern-Felsher explains that nicotine use through vaping has become a significant issue among youth, primarily due to its easy accessibility and the appealing marketing towards younger audiences. The discussion reveals a worrying trend:

“Vaping has increased dramatically… the statistics there, we saw upwards of 27 to 29% of teens using e-cigarettes… with a 78% increase in high school student use and a 48% increase in middle school use over those couple of years.” – Dr. Bonnie Halpern-Felsher

The marketing strategies employed are evidently tailored to entice a younger demographic, using flavors and packaging that mimic everyday items like USB sticks and highlighters, making them both appealing and stealthy.

The Scientific Concern

The rise of vaping introduces high levels of nicotine, an addictive substance, to the adolescent brain, which is still in development. This exposure can significantly impact neurological development and potentially lead to long-term addiction. Nicotine alters brain chemistry, increasing the risk of dependency and making quitting more challenging as the individual ages.

Cannabis Use and Its Implications

Dr. Halpern-Felsher also touches on the increased potency of cannabis products available today and their popularity among teens:

“THC levels… today’s joint is about 10 joints when I was a teen, so the dramatic increases in the potency right now that we’re seeing around THC… is of concern.”

The high levels of THC in modern cannabis can trigger or exacerbate mental health issues, particularly psychosis, in predisposed individuals. This is especially concerning given the ongoing development of the adolescent brain, which can be profoundly affected by such potent substances.

A Closer Look at the Risks

Studies suggest that the early use of high-THC cannabis is linked to an increased risk of psychosis and other mental health disorders. The alteration in brain chemistry due to THC can have long-lasting effects, potentially leading to chronic mental health issues if not addressed promptly.

Alcohol Consumption and Risky Behaviors

The podcast also highlights the correlation between alcohol consumption and risky behaviors in youth. Dr. Halpern-Felsher notes:

“We also discuss alcohol and some of the correlative as well as possibly causal data linking alcohol use to risky behaviors in young adults.”

Alcohol use can impair judgment and increase the likelihood of engaging in risky behaviors, such as unsafe driving and unprotected sex, which can have immediate and long-term health implications.

Mitigating Risks and Promoting Healthy Development

The conversation underscores the importance of understanding the factors that contribute to risk behaviors, including family influence, peer pressure, and media exposure. By addressing these factors, parents, educators, and policymakers can help steer youth towards safer behaviors and better health outcomes.


The insights from Dr. Halpern-Felsher provide a crucial understanding of the impact of youth risk behaviors on long-term health and well-being. By continuing to educate and intervene effectively, we can hope to mitigate these risks and promote healthier development for future generations.
