Nicotine (Cotinine) is not something that is routinely checked for in tox screens. However, it is a chemical, and it does leave traces in both blood and urine for 2 to 4 days. If the aim of the tox screen is specifically to discover evidence of smoking, then yes, a blood sample can show nicotine use.
