A randomized clinical trial of smokers trying to quit found that the effectiveness of particular smoking cessation therapies might relate to how quickly their body metabolizes nicotine. The study compared success rates of the nicotine patch versus the prescription medication varenicline.

Among participants with “normal” nicotine metabolic rates, varenicline was significantly more effective than the nicotine patch in helping them refrain from smoking at the end of treatment and six months following treatment. For “slow” metabolizers, there was no difference in success rates between varenicline and the nicotine patch, however there were fewer side effects experienced by those who used the patch. Prescribers can use this information to inform smoking cessation recommendations based on individual patient profiles.
