Smokers, if you are having trouble quitting, it may not be your fault. The problem could be in your genes.

A new study shows smokers with a gene variation linked to higher risk for heroin addiction may actually have an easier time quitting cigarettes.

The research is published in the journals Nature and Nature Genetics.

Researchers say the discovery could lead to more customized medical treatments to help smokers kick the habit.
