Connection Between Nicotine Consumption and Increased Depression and Anxiety Levels
A recent study published in the open-access journal *PLOS Mental Health* has revealed a significant association between tobacco product use and mental health difficulties among U.S. adolescents during a critical period of development. The study, led by Noor Abdulhay of West Virginia University, USA, and colleagues, analyzed survey data from over 60,000 middle and high school students collected between 2021 and 2023[1][3].
The research found that adolescents who use e-cigarettes, conventional tobacco products (such as cigarettes, cigars, hookah, and pipes), or both (dual users) have higher odds of experiencing symptoms of depression and anxiety compared to non-users[2]. Among these groups, dual users of both e-cigarettes and conventional tobacco show the highest risk of mental health difficulties[1][3].
The study reported that 21.37% of the surveyed students had used tobacco products, with 9.94% using only e-cigarettes, 3.61% using only conventional tobacco products, and 7.80% using both[3]. It also highlighted escalating rates of anxiety, depression, and suicide among adolescents in the United States (U.S.)[1].
Experts emphasize a complex, bidirectional relationship between tobacco use and mental health, meaning that tobacco use may contribute to worsening depression and anxiety symptoms, while existing mental health issues might increase the likelihood of initiating or continuing tobacco product use[2]. However, as this study is cross-sectional, it cannot definitively establish causality or the temporal direction of effects[2].
Key points from the study and expert commentary include:
- Adolescents who exclusively use e-cigarettes or conventional tobacco compared to non-users report higher depression and anxiety symptoms[1][3]. - Dual users of both e-cigarettes and conventional tobacco products exhibit the highest odds of depression and anxiety symptoms[1][3]. - The relationship is complicated due to potential confounding factors not fully controlled for, such as familial mental health history or other environmental influences[1][2][3]. - Longitudinal studies are needed to clarify whether tobacco use precedes mental health decline or vice versa[1][2][3].
In light of these findings, experts emphasize the importance of targeted interventions combining mental health support and tobacco prevention efforts for youth[1].
The study used data from the 2021-2023 National Youth Tobacco Survey[3]. Depression and anxiety symptoms were assessed using the Patient Health Questionnaire (PHQ-4)[1]. Tobacco use was categorized as ever e-cigarette-only, ever CTP-only, ever dual use, and non-use[3]. Overall psychological distress was categorized into normal, mild, moderate, and severe based on PHQ-4 total scores[3].
Three-quarters of eligible students completed the survey across the three years[3]. The journal where the study was published was the open-access journal PLOS Mental Health[3]. The study found that adolescents who use e-cigarettes, conventional tobacco products, or both, have a higher likelihood of reporting symptoms of depression and anxiety compared to non-users[3].
The findings underscore the urgent need for targeted mental health and anti-tobacco interventions for young people. Tobacco use, particularly e-cigarettes and dual use with combustible tobacco products, poses a significant threat to adolescent mental health[1]. Dual users, in particular, have the highest risk of mental health struggles[1].

- The study published in PLOS Mental Health, conducted by Noor Abdulhay and colleagues, suggests that adolescents who use e-cigarettes, conventional tobacco products, or both have a higher likelihood of reporting symptoms of depression and anxiety compared to non-users.
- Among these groups, dual users of both e-cigarettes and conventional tobacco products show the highest risk of mental health difficulties, according to the research findings of Abdulhay's study.
- The study also highlights the complex, bidirectional relationship between tobacco use and mental health, implying that mental health issues might increase the likelihood of initiating or continuing tobacco product use.
- In response to these findings, experts emphasize the importance of targeted interventions that combine mental health support and tobacco prevention efforts for youth, as tobacco use, particularly e-cigarettes and dual use with combustible tobacco products, poses a significant threat to adolescent mental health.
