Abstract
A discussion about disadvantages of electronic cigarettes (e-cigarettes) has recently broken out. There are even opinions that they are as harmful as regular cigarettes. However, this has not been proved, and theoretical premises suggest that e-cigarettes should be definitely less harmful as while using them, tobacco is not burned and harmful substances, in particular carcinogens are not produced. Certain premises assume that e-cigarettes may be used as a new form of nicotine replacement therapy, but this has not been confirmed yet. Therefore, further research into harmfulness and safety of the use of e-cigarettes is required. This paper presents solely reasons for the possibility of recommending e-cigarettes to people addicted to nicotine.
