3-4 days: A single cigarette will give a positive urine cotinine for 1-2 days, regular smokers generally 3-4 and rarely 5 days, and blood tests can detect it for about the same time. Oral swabs may detect if for a bit longer, up to 7-10 days, and it can be found in hair drug testing for months, depending on the length of hair chosen.
