Background: The electronic cigarette, often known as an ";E-cigarette"; or ";vaporizer,"; is a nicotine delivery device that has been hailed as a healthier option for smokers. Since electronic cigarettes were first introduced, both internationally and in the Kingdom of Saudi Arabia (KSA), they have seen rapid growth in popularity, especially among the country's youth and young adults. In addition, many formerly nonsmoking teens have taken up E-cigarette use. The safety profile of electronic cigarettes has been called into question by recent studies.
