Literature search sources were online databases such as PubMed, Medline, EMBASE, Web of Science, Google Scholar. Results: Following systematic search using inclusion and exclusion criteria, 21 articles were included in the final review. ECs result in an acute increase in cardiac Sympathetic Nerve Activity (SNA), pronounced as Electrocardiogram (ECG) changes resulting in a greater risk of sudden death for those with co-morbidities. ECs with or without nicotine can adversely affect lung function and can precipitate obstructive pulmonary diseases. ECs may also adversely affect oral health due to increased bacterial pathogenicity and periodontitis. At last, these nicotine-containing ECs can yield nicotine comparable to Traditional cigarettes (TCs) and sometimes to a much greater extent, thus posing the threat of the user becoming nicotine dependent.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Although ECs are less harmful
