Scientists at the University of California at San Diego believe that the reason for this – that the consumers of so-called «light» cigarettes stronger delayed in order to get the most powerful feelings from the process of smoking.
In the same study author David Burns believes that to reduce the risk of cancer among smokers of cigarettes can reduce the content of such substances as nitrosamines. This is one of the strongest carcinogens.

However, scientists note, reduction of nitrosamines did not make cigarettes safe.
