Maybe. In response, Jacob Sullum berates the FDA:
The fact that an FDA-approved, officially favored method of quitting seems to barely work at all underlines the stupidity of government resistance to alternatives such as snus and electronic cigarettes. One reason [nicotine replacement therapy] performs so poorly may be that it is designed and presented as a short-term medication to wean smokers off cigarettes rather than a long-term alternative that avoids all the health risks associated with inhaling tobacco smoke. Snus and e-cigarettes both show promise in that regard, and if public health officials truly were interested in reducing smoking-related morbidity and mortality they would let smokers choose the harm-reduction methods that work best for them instead of puritanically insisting on a goal of complete abstinence.
