I am a very occasional smoker. Saturday I had 5 cigarettes. None Sunday and one at 7am Monday. Monday afternoon at 2pm I had a cotinine test. Will I pass?

I am a very occasional smoker. Saturday I had 5 cigarettes. None Sunday and one at 7am Monday. Monday afternoon at 2pm I had a cotinine test. Will I pass?

Why do you ask?: Please forgive my frankness. I doubt you'll pass. If cotinine is detected, you can claim that you are around heavy smokers. But why are you doing this to yourself? Nicotine is treacherous, and if you play with it as you're doing, it will trick your brain into doing it more and more until you have a life-threatening addiction. No one deserves this slavery. Best wishes. ...Read more

How long could the presence of cotinine be detected in the blood, after smoking 10 cigarettes in 1 day?

How long could the presence of cotinine be detected in the blood, after smoking 10 cigarettes in 1 day?

Urine, not blood: Is what is usually measured, because it persists in urine far longer than in blood, and blood is harder to get (and the technology of detecting it is somewhat trickier, I understand). It persists in urine for about 2-3 days at most, and in lighter smokers or occasional smokers may be gone even within 24 hours. ...Read more

Can nicotine free cigarettes be detected in a urine cotinine test? Any help appreciated!

Can nicotine free cigarettes be detected in a urine cotinine test? Any help appreciated!

No: If you are not using nicotine in the heating chamber, and you haven't smoked tobacco in the last week, your test should be negative. I would point out that the safety of the propellant in these e-cigs (propylene glycol), as well as flavorings and additives, have never been subjected to study, and we simply do not know their long-term safety/dangers. They are likely safer than smoking tobacco though ...Read more

I have been smoking 8-10 cigarettes for last 10 years. I have a urine cotinine test in 20 days. Will I test Negative if I quit smoking 10 days before the test?

Cotinine: Levels of cotinine detected in urine vary due to a variety of factors including; the type of tobacco used, filtered vs. Non-filtered cigarette, how heavily the individual inhaled the smoke, the length of time an individual chewed, the number of cigarettes smoked per day, and the concentration of the urine. These variables make it difficult to determine exactly how much an individual uses tobacco. ...Read more

Does nicotine / continine from smokeless tobacco stay in system longer than cigarette nicotine / continine?

Does nicotine / continine from smokeless tobacco stay in system longer than cigarette nicotine / continine?

Drug metabolism: The same drug levels obtained via smokeless or smoking would be metabolized by the body at a similar rate. Differences in absorption and thus dosage may influence how long drug levels persist. Also, the mixture of drug and other metabolites may influence how long they persist. Tobacco companies have not released the dose-response data to compare these readily. ...Read more

However, people experience nicotine withdrawal within a few hours & most nicotine suffering is very severe within 20 hours. ...Read more
