Andrew Sullivan's blog linked to this interesting commentary in Reason looking at a new study that shows nicotine patches aren't very effective. Money quote:
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 NRT 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.
