University of Gothenburg Study Links Nicotine Use to Anxiety

Research from the University of Gothenburg indicates that adolescents using nicotine are more prone to anxiety, depression, and other mental health issues compared to their non-using peers. In a study involving nearly 3,000 Swedish high school students, almost 80% of girls who used nicotine reported clinically significant anxiety symptoms.

The studies examined both traditional tobacco products and newer nicotine products, such as pouches and e-cigarettes. A follow-up study of about 1,500 adolescents revealed that those who smoked exhibited more depressive symptoms and suicidal thoughts.

Girls whose tobacco use increased over time faced worsening mental health issues, including anxiety and sleep problems. Johanna Andersson, a physician and PhD student at the Sahlgrenska Academy, emphasized the need for further investigation into the gender differences observed.

Professor Louise Adermark, a principal investigator, noted that while the studies show consistent patterns, they do not establish a direct cause-and-effect relationship between nicotine use and mental health problems. The research also considered various factors influencing mental health and nicotine use.
