Is smoking cigarettes genetic?

Tobacco smoking is believed to be a complex, multifactorial behaviour with both genetic and environmental determinants. While early reports suggested that the influence of heredity on smoking was modest, more recent studies have found significant genetic influences on several aspects of smoking behaviour.

How is nicotine dependence Genetic?

A DNA variant — located in the DNMT3B gene and commonly found in people of European and African descent — increases the likelihood of developing nicotine dependence, smoking heavily, and developing lung cancer, according to a new study.

Does smoking affect your genes?

The habit can add chemical modifications to genes involved in cancer. Cigarettes leave you with more than a smoky scent on your clothes and fingernails. A new study has found strong evidence that tobacco use can chemically modify and affect the activity of genes known to increase the risk of developing cancer.
