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. Those who carry the gene mutation find it very hard to give up smoking.

Young people who carry this mutated form of the CYP2A6 gene find it especially hard to quit cigarettes.
