Smokers can inhale less amount of nicotine if they smoke low-nicotine cigarettes and do not return to cigarettes they light up earlier, in accordance with last study.
In a study, in which 135 smokers between the ages of 18 and 70 took part, cigarette users who began to smoke cigarettes with less nicotine did not equalize by smoking more cigarettes and inhaling more tar and toxins.
According to Neal Benowitz, UCSF nicotine researcher who led the study, the matter was to lessen the amount of nicotine that is inhaled by smoking people in order to they get accustomed to the lower nicotine levels, and ultimately come to the conclusion that they need no more smoking.
The findings from this new study differ greatly from those got form studies led years earlier by Benowitz and others on previous generations of so-called low-nicotine cigarettes.
For a long time University of California San Francisco has been a leader in analyzing methods for quitting smoking, in showing marketing practices of tobacco companies, in creating public health programs concerning tobacco, and in leading biological study focused on better understanding of nicotine addiction and sensitiveness. UCSF as well is a place where Tobacco Control Archives —a wealth of legal documents and other materials- are kept.
The U.S. Food and Drug Administration (FDA) has been authorized to control the content of nicotine in cigarettes which are sold in the United States, but has not yet proceeded to action. In accordance with Benowitz, who is a member of the agency’s Tobacco Products Scientific Advisory Committee, FDA did not act because of the lack of scientific evidence.
However, recent innovative studies by Benowitz and others have increased chances that a new type of low-nicotine cigarette could help smokers in smoking cessation and prevent tobacco addiction among young people. The FDA, together with the National Institutes of Health (NIH) now has committed funds for larger studies — not yet begun — to further examine the strategy.
Smokers’ nicotine intake decreased essentially as the content of nicotine in cigarettes was reduced, Benowitz and colleagues made a conclusion in their last published analysis of the study findings, which was in online journal Cancer Epidemiology, Biomarkers and Prevention at February. The investigators measured levels of cotinine, a metabolic byproduct detectible in blood, as a pointer of nicotine intake.
“The reduction of content of nicotine in cigarettes does not seem to be harmful to smoking people, as proved by no rise in cigarettes smoked per day and no rise in exposure to tobacco-smoke combustion products,” Benowitz said
