A group of common genetics variants that affect the nicotine receptors in the nervous system could significantly increase the risk of developing nicotine addiction. These results, which could have powerful implications for policy preventing tobacco use in young people, were published on July 11, 2008 in the open-access journal PLoS Genetics. Single nucleotide polymorphisms (SNPs) are variations in the genetic sequence that involve a single unit of DNA.
