How To Pass A Cotinine Blood Test
If you are a non-smoker but smoked 3 menthol cigarettes are you able to pass a cotinine blood test?
What do you advise if i smoke a pack a day how long before cotinine is out of my blood so i can pass a blood test?
3-4 days: at most. Nicotine is a short-acting drug, and is metabolized into cotinine, which can be detected in blood for 1-2 days, in urine 3-4 days at most. More important than passing the "smoking" drug test is QUITTING TOBACCO. I encourage you to strongly consider getting into a formal tobacco cessation program. ...Read more
I am not a smoker but had a few cigs while drinking a few weeks ago. How likely am i to test positive for cotinine on a blood test?
Not likley: A week for an occasional user is enough to clear the nicotine from your body, provided you have not been exposed to second hand smoke. Combining alcohol and tobacco is a very bad idea and their toxic effects are synergistic. Avoid tobacco, always, and have no more than one drink a day. ...Read more
I smoked 1 cigarette 14 days before an upcoming blood test for Cotinine. Smoked 0 cigarettes 2 months prior. Will test be negative for Cotinine?
Yes: cotinine is positive for a few days as most after one cigarette, depending on whether it is a blood test, oral swab or urine test, but after discontinuing smoking, even oral swabs (which appear to be the most sensitive) will be negative by 5 days later. ...Read more
I had quit smoking, i smoked 10 cigs in 1 day. Can i pass a nicotine/metabolite blood test 4 days later?
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
Hey i know somebody that smoked maybe half a gram of weed and smokes maybe once every 3 months how can they pass it if they skinny and 5'8 blood test?
Probably: This isn't the place to talk about the wisdom of these laws or this testing. A very low level, which is what your friend will have is they didn't smoke a few days before the test, might be blamed on 'passive exposure.' try to avoid the stuff if you're likely to be tested until the laws change in your area. ...Read more
