Some of us have a genetic mutation that makes it more difficult for the body to rid itself of nicotine. If you are one of those types, you are more likely to become heavily addicted to nicotine, or smoking, say researchers.

NEW YORK  - Gene variants that lead to   decreased amounts of an enzyme known as GSTM1 may raise the   risk of lung cancer related to radon exposure, new research   suggests. The gene variants also seem to increase the   cancer-causing effect of secondhand smoke.
