Smoking and Tobacco
I see so much conflicting information on how long cotinine lasts in the system. As a medical professional, could you tell me: would cotinine be detected in testing (blood, urine, or hair) of someone who regularly chewed tobacco but had quit completely, no patches either, for 4-5 months? How about 7-8 months? (Also young and in good health.) Thank you.
Thank you for visiting NetWellness. It is beyond the scope of NetWellness to answer questions concerning drug screens. However, the article Drug Testing may help you better understand the drug screening process.
