You should: Am not aware of people preferring blood tests to urine tests for cotinine, particularly since it can be found in blood only for a few hours after smoking, while it persists in urine for several days. In any case, testing should be negative 4 days later. More important than passing the test is actually quitting smoking, and taking care of your health. Please quit and stay quit! ...Read more

Does it take 4 weeks for nicotine to get out of your blood system and not show up in a test?

Does it take 4 weeks for nicotine to get out of your blood system and not show up in a test?

Possibly: Nicotine is highly fat-soluble, so it may be stored in fat cells. Half-life of nicotine is ? 2 hrs, but its metabolite cotinine's half-life is 20 hrs. Ideally after 8 days only 1/1000th of the original amount should remain. Asians metabolize nicotine more slowly, & urine acidity (ph) affects excretion. If nicotine/ cotinine still shows after 4 weeks, it must be being released from fat. ...Read more

How long does it take nicotine to get out of blood?

How long does it take nicotine to get out of blood?

24-48 hours: nicotine is usually not what is tested for, but its main metabolite cotinine. Nicotine is extremely short-acting - that is why people smoke 20 cigarettes a day (or about one an hour when awake). Cotinine lasts longer, and can be found in blood for 1-2 days and in urine for 2-3 days. Oral swabs can detect it potentially for slightly longer. ...Read more

How long does nicotine stay in the blood?

How long does nicotine stay in the blood?

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. Nicotine per se stays only for a few minutes, and is metabolized to cotinine, an inactive metabolite, which is what is generally tested for. Thats why people smoke 20-30 puffs for each cigarette, and smoke 20 or more cigarettes per day. ...Read more

I have a blood test in 9 days they're testing for nicotine is there any chance I can get my levels down to 0 by then?

Stop now: Nicotine test, actually it is a test for cotinine, a metabolite of nicotine, it is usually done on urine or oral fluid. Do not use tobacco in any form, including nicotine replacement patches, gum etc., avoid exposure to second hand smoke from now onward. Cotinine is usually detectable for a week after cessation of exposure. ...Read more
