Should pass: If you have a low level, claim passive smoking. That said, please forgive my frankness. You need to comply with your tobacco abstinence program. It is hard, but it is life and death. Do whatever gives you strengt to pursue it and hang in there. ...Read more

Don't smoke again: There is nothing you can do other than not smoke any more. You may still pass depending on the type of test. You will pass a blood test after 1-10 days depending on the type, a urine test after 3-4 days and a saliva test after 1/2-4 days. If you have abstained for a week prior today you will probably pass if you just had 1 today. Stopping for good is the best thing you can do for your health. ...Read more

How long will nicotine show up in an oral fluid test?

Up to a week: depends on how much you smoke and the amount of nicotine in the cigarettes, to some extent. In general urine tests and blood tests for cotinine will show positives for 3-5 days, oral swabs potentially a little longer. ...Read more

What to do if I need to pass a nicotine test?

Dr. Alan Wartenberg
Board Certified, Addiction Medicine

Don't use nicotine: If you are smoking or chewing tobacco and your employer (or whoever) is testing for it, it is going to test positive unless you quit. Cotinine, the main metabolite that is usually tested for, will remain positive 3-4 days in most tests, up to a week for more sensitive tests. You can find websites on "beating" tests, but most of these don't work, and testing companies now test for them/ ...Read more

Nothing: You have to let it pass. Drinking more water may help a tiny bit. But really, if you know a urine test is coming up and they are checking for nicotine, don't use nicotine. ...Read more

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

Dr. Ralph Morgan Lewis

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 nicotine stay in your system so that it will be undetected by a saliva test?

Approx 72 hrs: I believe it clears the system in approximately 72 hours, usually detected by a blood or urine test. If this is being asked to "get around" insurance questions, i take exception to not being honest. ...Read more
