A new national study has found that older, impulsive U.S. adolescents with a history of substance use are significantly more open to vaping and smoking, raising fresh concerns about the risks posed by e-cigarettes and tobacco products among youth. The research, led by the University of Nebraska Medical Center and published November 20, 2025 in the Journal of Adolescent Health, analyzed over 9,300 adolescents aged 12-13 years and highlights the influence of impulsivity, parental monitoring, and previous substance use on teens’ willingness to experiment with nicotine products.

Key Findings

Researchers used data from the Adolescent Brain Cognitive Development study, collecting information between 2019 and 2021. Key observations include:

Most resist use, yet risk groups persist: Over three-quarters (76.8%) of surveyed adolescents reported no interest in vaping or smoking, but 11% were susceptible to both tobacco products, while 6.1% were open only to vaping and another 6.1% only to cigarettes.
Who is most susceptible? The risk of openness to nicotine use increased with age, was higher among girls, and spiked for those with a prior history of alcohol or drug use. Traits linked to impulsivity, like sensation seeking and acting rashly on negative emotion, were also associated with increased curiosity and willingness to try vapes and cigarettes.
Parental monitoring has protective effects: Higher levels of parental involvement and supervision were consistently associated with lower susceptibility to all forms of tobacco product use, with particularly strong protection against vaping and dual use.

Expert Perspectives

Dr. Jiani Zhang, the study’s lead author, emphasized the need to identify and support youth who are not only older and impulsive, but might also already experiment with substances: “Prevention efforts should take into account these risk factors and strengthen family and school environments to protect adolescents particularly vulnerable to vaping and smoking initiation”.

Independent experts echo these concerns. Dr. Michael Rao, a tobacco and cancer control advisor, notes that “flavored vaping products and social media marketing are driving high rates of e-cigarette use among adolescents.” He further warns of short- and long-term health effects, including respiratory problems, nicotine poisoning, and negative impacts on brain development.

Research published in the Journal of Adolescent Health and summarized by the CDC details how nicotine can harm the developing brain into the mid-20s, reducing impulse control, affecting mood and learning, and fostering greater risks of future addiction.

Context and Background

Why Impulsivity Matters

Previous studies support these new findings. Adolescents who show traits like sensation seeking or who act on urges without considering long-term consequences are more likely to start vaping or smoking, raising their lifetime risk for nicotine dependence and associated diseases. In addition, adolescents’ brains are particularly vulnerable to addiction, and e-cigarettes can increase impulsivity, heighten physical and mental health risks, and serve as a gateway to further substance use.

Evolving Trends and Dangers

E-cigarettes are often perceived by youth as less harmful than traditional cigarettes, but they expose users to a range of dangerous chemicals, including those that damage the lungs, heart, and liver.
Advertising and sweet or fruit-like flavors are major factors in teen experimentation. Social media plays a significant role in normalizing use and undercutting warnings about harms.
The onset of nicotine use at young ages is likely to reinforce negative habits and dependence that can persist into adulthood, affecting health and daily functioning.

Implications for Public Health

For Families: Parental monitoring and open conversations about health risks can be critical. Practices such as setting clear expectations, asking about peer behavior, and supervising social environments are shown to lower the chances of teen nicotine experimentation.
For Public Health Authorities: The study urges policymakers and educators to deliver targeted preventive interventions for high-risk teens, considering both individual (impulsivity, prior substance use) and environmental (family, community, media) factors.
For Healthcare Providers: Regular screening for impulsive behavior, substance use, and mental health concerns during adolescent checkups can help identify those in need of early intervention.

Limitations and Counterpoints

The study relied on self-reported surveys, which may be affected by social desirability or recall bias.
Because the data were mostly collected during the COVID-19 pandemic, the unique circumstances of social restrictions may limit how broadly results apply.
The cross-sectional design precludes drawing firm causal conclusions, though the associations remain robust across similar research.
Critics argue that while impulsivity is a recognized risk factor, policy must also address broader determinants such as socioeconomic status and community context.

Practical Takeaways for Readers

Teens and families should be aware that curiosity or impulsivity can drive experimentation, and that even limited exposure to nicotine can initiate a cycle of addiction.
If a teen shows rising curiosity, sensation-seeking, or is exposed to permissive peer or family attitudes, early honest conversations and increased supervision are advised.
Choosing tobacco-free lifestyles supports not only long-term health but also protects developing brains from the risks of addiction, mental health decline, and future substance use.
