The use of electronic cigarettes (e-cigarettes), or vaping, has become increasingly common in recent years. There are growing concerns that exposure to tobacco advertising, promotion and sponsorship (TAPS) is a risk factor of youth e-cigarette use. To investigate, researchers surveyed school students aged 11-17 years to collect data on their use of electronic and combustible cigarettes. The research team identified cases of vaping and non vapers, and then interviewed the students about their exposure to TAPS. The table below presents the study findings.
