Electronic cigarettes (e-cigarettes) have substantially increased in popularity. Clear evidence about the safety of e-cigarettes is lacking, and laboratory experiments and case reports suggest these products may be associated with potential adverse health consequences. The effectiveness of e-cigarettes for smoking cessation is modest and appears to be comparable to the nicotine patch combined with minimal behavioral support. Although a role for e-cigarettes in the treatment of tobacco dependence may emerge in the future, the potential risk of e-cigarettes outweighs their known benefit as a recommended tobacco treatment strategy by clinicians. Patients should be counseled on the known efficacy and potential risks of e-cigarettes.
Clinicians are ethically obligated to promote smoking cessation using evidence-based treatment strategies. Smokers will ask about e-cigarettes, and we must be prepared to offer appropriate counseling. With the evidence available to date, clinicians must be circumspect in recommending e-cigarettes for use by cigarette smokers interested in quitting smoking for the following reasons:
1. They are not demonstrably superior to FDA-approved medications for smoking cessation.
2. They may not be effective for smoking cessation and dual use (ie, using e-cigarettes and continuing to smoke) will prolong exposure to tobacco.
3. They are not FDA-approved for the treatment of tobacco dependence.
4. Short-term safety data suggest they may cause airway reactivity.
5. The long-term health risk of exposure to e-cigarette constituent chemicals is unknown.
6. No regulatory oversight, such as requirements for good manufacturing practices, is currently in place for e-cigarette devices or e-juice.
More clinical safety data and increased product reliability and regulation are needed before e-cigarettes can assume a place in the standard clinical approaches to the treatment of tobacco dependence.
