Recent reports highlight a growing concern over youth vaping, with Singapore implementing stricter measures in response to an alarming rise in teen addiction, including cases as young as 10 years old. A major study indicates that young people who vape are three times more likely to begin smoking cigarettes, and vaping is associated with increased risks of asthma and poor mental health. Public health experts advocate for stronger regulations to protect teenagers from vaping-related harms. However, some earlier research, such as a 2018 review by Public Health England, suggests e-cigarettes are substantially less harmful than smoking and do not necessarily lead youth to start smoking. Critics of current studies point to methodological limitations, including reliance on self-reported data and confounding factors, calling for randomized controlled trials to better understand vaping risks. Additionally, youth vaping has been linked to increased use of tobacco, cannabis, and alcohol, raising broader concerns about substance use among adolescents.
