Aim of the review This systematic review provide an analysis of the existing literature on the influence of e-cigarettes on the human body with their economic and behavioral aspects. By examining a wide range of studies, we aim to elucidate the potential risks and benefits associated with e-cigarette use and provide a comparison of both electronic and conventional forms of nicotine consumption. Methods A systematic search was conducted using electronic databases such as PubMed, Scopus, and Web of Science. Keywords included "e-cigarettes", "vaping", "health effects", "conventional cigarettes", "tobacco", "respiratory system", "cardiovascular system", "immune system", "oral health", and "cellular effects". The search was limited to studies published up to December 2023. Both observational and experimental studies were included. Conclusion While e-cigarettes…
