Brief Summary

Electronic cigarettes (E-cigarettes) have gained significant popularity as an alternative to traditional combustible tobacco cigarette smoking. E-cigarettes are marketed as a safer alternative to conventional smoking forms. Many chronic smokers suppose that e-cigarettes are risk-free and can be used effectively as a smoking cessation tool. The market size of e-cigarette is increasing because of its rising popularity among the youth even though it is not an approved Food and Drug Administration (FDA) product yet
