When someone uses tobacco or nicotine products, their body metabolizes nicotine into cotinine, which can be detected in blood, urine, saliva, or hair
The genes are also responsible for the production of chemical messengers that communicate the feelings of pleasure and reward that come with smoking, which are what compel a smoker to persist with the habit, even past the physically harmful effects of smoking
