Cigarettes labeled as Lights, Milds, or Low-tar, are considered to have a lighter, less pronounced flavour than regular cigarettes. These cigarette brands may be listed as having lower levels of tar, nicotine, or other chemicals (as ''inhaled'' by a smoking machine). However, the scientific evidence is that switching from regular to light or low-tar cigarettes does not reduce the health risks of smoking or lower the smoker's exposure to the nicotine, tar, and carcinogens present in cigarette smoke.

is there less nicotine in ultra light cigarettes?
no
