Can Science Make Cigarettes Safer?
Mignon Fogarty | Mar 23, 2003 | 4 min read
Courtesy of Vector Tobacco  READY, SET, STOP: Quest's 'step down' low- and no-nicotine cigarettes. The major toxins in cigarettes, perhaps surprisingly, don't come from the chemicals that manufacturers add. "The carcinogens mostly come from the burning of tobacco," says Kenneth Warner, director, University of Michigan Tobacco Research Network. Just burning tobacco also produces carbon monoxide, a big contributor to heart disease. So, tobacco companies are turning to science to make ciga
