Question 1

how long can cotinine be detected in saliva tests?

Accepted Answer

Variable, but the: Companies that manufacture the tests say that saliva can remain positive for 7-10 days, whereas blood and urine tests are generally negative within 3-5 days.

Question 2

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

Accepted Answer

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.

Question 3

Accepted Answer

Thanks for asking!: Up to 30 days.

Question 4

Depends on what is : Tested. Urine is the usual substance tested and nicotine metabolite can be detected for 3-5 days after exposure to tobacco. Cotinine stays for much longer in nails and hair. See this article for more info.

Question 5

is cotinine out of your system within 3 weeks?

Accepted Answer

Should be.: Cotinine, a chemical your body makes from nicotine, has a half-life of 20 hours. Most drugs are non-detectable after 5-6 half lives.

Question 6

can i get cotinine out of my system in 5 days?

Accepted Answer

Likely, if no more : Tobacco. There are variations in elimination with type of tobacco, lean body mass, race and gender. Average half life of cotinine is about 20 hours so on average five days would allow 5 half lives which is usually sufficient to test negative. Please note that these are averages and may not apply in an individual person. See this site for more info.

Question 7

how long smoke free to pass a cotinine levels test?

Accepted Answer

3-4 days: depending on which test is used.  But please STAY QUIT.  Don't just do it for the test, but for your health and life, and for your loved ones.

Question 8

how long does it take for cotinine to get out of your system?

Accepted Answer

2-3 days: nicotine is a very short-acting drug, and its main metabolite cotinine is too.  After a single cigarette, levels will usually only be detectable for 24 hours, and most regular smokers will be detectable for 3 days or so. Depends on how it is tested, with oral swabs picking it up for longer, blood tests have a shorter window, urine is in the middle. I suggest smoking cessation.

Question 9

if i smoked one cigarette and have a medical exam for insurance in 8 days will the cotinine still be present?

Accepted Answer

What is being tested: “If you smoke infrequently, cotinine will usually be present in your urine for about four days. With regular exposure to nicotine, cotinine may be detectable for up to three weeks after your last exposure.”  REF:  https://www.healthline.com/health/quit-smoking/how-long-does-nicotine-stay-in-your-system#nicotine-inurine

Question 10

how can i pass a cotinine test?

Accepted Answer

By not smoking: If you smoke, however they do the test (blood, urine or oral fluids), it will be positive.  Ways to "beat" drug-testing mostly don't work, are detectable by current systems and make it worse for you.  If you are a smoker, you are responsible for the consequences of your smoking. Helping you avoid consequences is NOT helping you. Get help quitting tobacco.
