I have to pass a nicotine test on Monday, and I slipped today and had a cig. what do I need to do so I can pass, I only had the one.

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

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

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

Is nicotine and cotonine present in the system of someone that is surrounded my secondhand smoke? and is it enough to register on a cotonine test?

Generally no: the "set-points' of most drug tests are put where the data indicate that casual second-hand exposure (like riding in a car with someone smoking), or exposure to clothing, furniture etc with cigarette smoke residue, will NOT show up. If highly sensitive tests are used, small amounts of cotonine may show up, but most tests are geared to 50 ng/ml, which should not give positive results from exposure. ...Read more

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

I had a few puffs of an e-cig(17-24mgs of nicotine) on Friday and have to take a nicotine test tomorrow. will I be able to pass?

Not entirely sure: It depends on how they test you and what they are testing you for (nicotine or cotinine). If it's the most common urine test it can stay there for up to 3-4 days so you're on the threshold of that. The standard positive test for urine is 200ng/ml.Blood tests is negative 1-3 days after last cigarette. Saliva test is 2-4 days. Good luck! ...Read more
