How do the Genetics of Nicotine Metabolism Relate to Smoking and Treatment ?

(4 of 10)

  • Individuals with low activity variants in cytochrome P4502A6 that metabolizes nicotine and cotinine have reduced metabolism of nicotine, smoke less and have higher nicotine levels while on nicotine patch treatment. Slower nicotine metabolizers have a higher quit rate on nicotine patch treatment.
