Cigarette smoking is associated with many health risks and complications. Despite smokers' strong desire to quit, most battle with nicotine withdrawal and relapse. Because electronic cigarettes (e-cigarettes) do not contain tobacco, some believe them to be safer than traditional cigarettes and have used them as a replacement or adjunct nicotine source to prevent withdrawal symptoms. Electronic cigarettes are designed to mimic traditional cigarettes and expel a vapor composed of nicotine, water, glycerol, propylene glycol and other flavorings. Many e-cigarette companies use appealing platforms, which promise smoking cessation and harm reduction, to attract consumers; however, several studies have found e-cigarettes actually contain ingredients that are harmful to one's health. Studies have demonstrated that the use of e-cigarettes can be toxic to patients' health if patients do not research the products they intend to purchase. The flavoring of e-cigarettes may be a major contributor to e-cigarette cytotoxicity. If flavoring and other cytotoxic contents of e-cigarettes can be eliminated, e-cigarettes may be useful in smoking reduction and cessation. Many clinicians today support traditional forms of nicotine replacement therapy for smoking cessation rather than e-cigarettes. Due to the lack of regulation and studies by the U.S. Food and Drug Administration, e-cigarettes may not be as safe as users may perceive and should not be a preferred product for smoking cessation therapy until they are further studied and regulated.
