It seems that claims that light cigarettes have the benefit of being safer
because of low tar and nicotine is not correct. A National Cancer Institute
study indicates that in most cases light cigarette manufacturers are
misleading comsumers. Apparently the light cigarettes trick the smoking test
machines into recording artificially low levels. If you go to
https://www.lawyersandsettlements.com/case/light_cigarettes_misleading_safety_benefits
there is more information on this and what can be done about it. There is
also a free case evaluation provided for those who might have been affected
by this. I hope that this may be of some help.
