This problem-based report analyzes the use of e-cigarettes among the British population to understand their role in reducing smoking-related deaths. The report begins with an introduction outlining the research problem and aim, followed by a literature review that examines existing research on e-cigarettes, vaping, and their impact on public health. The methodology section details the qualitative research approach and thematic analysis used to analyze secondary data from the Office of National Statistics (ONS). The data analysis and interpretation section focuses on the ONS data, exploring reasons for e-cigarette use and the role of e-cigarettes in smoking cessation. The report highlights the motivations behind quitting smoking, both intrinsic and extrinsic, and how e-cigarettes can aid in this process. The conclusion summarizes the findings and provides recommendations on how to lower smoking-related mortality, including strategies like intrinsic motivation, switching to e-cigarettes, smoking cessation programs, counselling, and medication. The report emphasizes the potential of e-cigarettes as an extrinsic motivational tool, especially for individuals lacking intrinsic motivation to quit smoking. The report aims to provide actionable insights for public health initiatives to reduce smoking-related deaths in the UK.
