Smokeless tobacco more effective than cigarettes for delivering dangerous carcinogens into the body
PHILADELPHIA It may not be inhaled into the lungs, but smokeless tobacco exposes users to some of the same potent carcinogens as cigarettes.

...ssue-damaging substances like silica and asbestos, inhaled into the lungs, has also been shown to increases lung cancer risk.
