2-3 days: nicotine is a very short-acting drug, and its main metabolite cotinine is too. After a single cigarette, levels will usually only be detectable for 24 hours, and most regular smokers will be detectable for 3 days or so. Depends on how it is tested, with oral swabs picking it up for longer, blood tests have a shorter window, urine is in the middle. Hair tests can go back months.How about stopping?
