Nicotine is an alkaloid poison that occurs in tobacco. It is also used in medicine and as an insecticide. Some organizations or agencies may prefer non-smoking employees. Such agencies frequently take assistance of Nicotine tests to detect tobacco usage by potential employees or individuals at a particular point of time. Nicotine is metabolized into 20 different metabolic products out of which, cotinine is used as a biomarker for nicotine testing as half-life of cotinine is comparatively higher than other metabolites and can be detected for up to 3-5 days upon last nicotine use. Nicotine can be tested for by the presence of nicotine or its metabolites in hair follicles, urine or saliva samples as in the case of other drug/metabolite detection tests. Nicotine test is based on the principal of immuno-screening techniques coupled with HPLC, RIA, and Gas chromatography analysis. A positive detection of cotinine in human urine requires at least 200ng/ml cut-off levels. In some cases hair follicle based tests are used for testing the presence of nicotine/cotinine during pre employment drug screening. The advantage of using hair tests is that abstinence or adulteration of the specimen shall not be able to defeat the test. The drug remains in hair for as long as 90 days and can reveal medication/drug usage history of as much as past 6 months!
depending on the amount you used and the sensitivity of the hair follicle test it is detectable for a very long period of time. Up to 90 days.

While THC can be detectable in hair follicle tests, taking just 3 small hits where you didn't inhale deeply may result in lower levels of THC in your system, which could potentially be below the threshold for detection in a hair follicle test. However, the detection window for hair tests is longer than other methods, so it's not guaranteed that it won't be detected.
A single long white hair on the face could be caused by aging, genetics, stress, or a lack of pigmentation in the hair follicle.
Don't smoke meth
One to two years. It stays in the hair. Better not to use at all.
