Cotinine can be measured in urine, and routinely is for companies who do not want to hire (or retain) cigarettes smokers, because of their increased health care costs and absenteeism. Cotinine remains in urine for about 3 days after a cigarette, perhaps a bit longer in chronic heavier smokers.

I agree with comment. Nicotine can and frequently is tested for in the urine of smokers, particularly people who should not be smoking.
