The half-life of cotinine in the bloodstream is about 16-20 hours. This means that after you smoke a cigarette, the level of cotinine in your bloodstream will reach its peak within 30 minutes and then gradually decline over the next 16-20 hours. However, cotinine can be detected in the bloodstream for up to 10 days after you quit smoking.
