Reducing harm caused by tobacco. Research findings from the University of Minnesota.

Researchers from the University of Minnesota Transdisciplinary Tobacco Use Research Center have spent the past 5 years exploring ways to evaluate exposure to tobacco toxins in smokers and nonsmokers and reduce the associated health risks. This article discusses research into the health effects associated with smokers reducing the number of cigarettes they consume and using lower-tar cigarettes, modified tobacco products, and smokeless tobacco. Researchers found little, if any, benefit to products that promise less exposure to cancer-causing tobacco toxins.
