Cotinine can be detected in the blood for up to four days after it was last used.

Cotinine is an important alkaloid found within tobacco and a metabolite of another chemical in the substance - nicotine.

The alkaloid is not as potent as nicotine and can be used in medicine as an antidepressant, usually under it's brand name Scotine.

It's a breakdown product of nicotine and can stay in the system for 2-4 days after smoking. If you are chronic smoker then excretion can be delayed.
