Curiosities: No proof that lasers help people stop smoking

Q. There’s a new stop-smoking treatment being advertised on TV somehow using lasers. What is this and how does it work?
A. The method uses low-power lasers to stimulate parts of the body much like acupuncture. The catch, according to Michael Fiore of the UW-Madison Center for Tobacco Research and Intervention, is that acupuncture as a means to quit puffing has not been determined by the U.S. Public Health Service to be effective and is not supported by science.
