A new study has found a significant connection between internalizing mental health symptoms—such as anxiety, depression, and loneliness—and increased nicotine use among youth aged 16 to 19. The research, led by Emily Hackworth, a 2024 Ph.D. graduate from the Arnold School of Public Health’s Health Promotion, Education, and Behavior program, suggests that young people struggling with mental health issues are more likely to turn to nicotine products, particularly electronic cigarettes (e-cigarettes). The study, published in Nicotine and Tobacco Research, also points to the impact of the COVID-19 pandemic in exacerbating this trend.
The study highlights that 87% of individuals who smoke report trying tobacco products before the age of 18, with many continuing to use them into adulthood. Previous research has established a bi-directional relationship between mental health struggles and cigarette smoking, with adolescents being especially vulnerable due to the significant physiological, psychosocial, and emotional changes they experience during this critical developmental stage.
E-Cigarettes and Mental Health: A Growing Concern
Hackworth and her team sought to explore whether this relationship extended to specific types of nicotine products, such as combustible cigarettes versus non-combustible options like e-cigarettes, or whether both types of products contributed to the growing trend. The research analyzed data from over 80,000 adolescents in Canada, England, and the United States, collected between 2020 and 2023, through the International Tobacco Control Adolescents Tobacco and Vaping Survey.
The findings showed that internalizing mental health symptoms were strongly associated with both combustible and non-combustible nicotine use, with the strongest correlation found in the use of non-combustible products, primarily e-cigarettes. This suggests that adolescents with poor mental health are not only more likely to experiment with nicotine products but may also be particularly drawn to e-cigarettes.
The Need for Further Research and Public Health Intervention
Hackworth notes, “Non-combustible product use may have a particularly strong relationship with poor mental health among adolescents, though we need additional research to better understand this connection.” She emphasizes that the trends observed are largely driven by e-cigarette use, which has surged in popularity among youth in recent years. As such, public health efforts to reduce youth e-cigarette use should consider highlighting the product’s association with mental health challenges. Moreover, initiatives promoting e-cigarettes as a safer alternative to traditional cigarettes may need to address the potential risks linked to vaping and mental health in young people.
This study underscores the need for a deeper understanding of the relationship between mental health and nicotine use, particularly as vaping continues to rise among adolescents. Further research is essential to develop effective strategies for preventing nicotine use among youth and addressing the underlying mental health issues that contribute to this trend.
