Evaluation of scientific studies on electronic cigarettes in the last five years
Abstract
Electronic cigarettes are not as harmless as claimed and contain substances known to be hazardous to human health. E-cigarettes include chemicals similar to those found in conventional cigarettes, such as formaldehyde, acetaldehyde, acrolein, diethylene glycol, nickel, chromium, and lead. In recent years, their use has become increasingly widespread in Türkiye, as in many other countries. The characteristics of these devices, their effects on human health, and their potential role in smoking cessation have attracted global attention. In this context, general information about e-cigarette devices and their usage, as well as studies conducted on these devices, have been reviewed. The studies in this area include surveys, clinical observational studies, and both clinical and interventional research investigating potential harmful effects. Currently, there is insufficient scientific evidence regarding the safety of e-cigarettes. Although it is often claimed that these products do not contain tobacco, they do contain nicotine, which is known to cause addiction. The aim of this review article is to highlight the characteristics of electronic cigarettes, their impact on human health, their global use, and to provide an objective perspective by examining the existing literature on the subject.
