Nicotine use may not only be evidenced based on one’s
symptoms; some diagnostics are currently available to find nicotine within the
body.
When one smokes, nicotine indrawn is then metabolized into
cotinine in organs like the lungs and also the liver, and after excreted in the
urine. Apart from the nicotine, cotinine could be a strong biomarker and
indicator for nicotine use, detectable in the urine, blood, and saliva as well.
The length of time that nicotine stays in the body and
cotinine will be a reliable indicator of nicotine use depends on the quantity
of tobacco smoked, the number of years smoking tobacco, and also the kind of
nicotine test performed. It will be as short as a couple of days, or as long as
three months.
How long does nicotine stay in Your Blood?
Nicotine is metabolized into cotinine, which then admixes
with blood. The Liver detoxification
process then takes place, facilitating removal of toxins from the blood. This
method is slow compared to the elimination of waste produced by the kidney in
the form of urine that takes place at a quicker rate.
In these blood tests, nicotine is visible typically one to
three days after last use of a nicotine-containing product, like cigarettes,
smoke-free tobacco, and nicotine patches or gum. This could also vary in part
of the amount of nicotine use, and therefore the individual’s health and age.
On the other hand, when cotinine levels are used for
determination, it's going to take one to ten days till the levels are
undetectable from the blood.
However, a variety of reasons can result in false positive
results of nicotine in the blood. These include working at metal purification
areas where high levels of thiocyanate present, consumption of thiocyanate
containing foods like cabbage, broccoli, almonds and mustards, and intake of
medicines like amphetamines. Laboratory errors should even be thought of.
How long does nicotine stay in your urine?
When inhaled, nicotine is converted into cotinine that in
conjunction with the body’s wastes products is excreted in the urine. In
detecting nicotine and its metabolites within the body, levels stay detectable
in the urine just for three to four days.
However, this might be different for some cases. For passive
smokers, urine nicotine check may be positive for as long as fifteen to twenty
days. Cotinine might also take longer to be excreted with wastes if menthol
cigarettes are used.

Nicotine saliva test:
This is known to be the most accurate nicotine drug test and
is most preferred. It doesn't only eliminate the necessity to handle urine
specimens, however, it may also provide an approximate quantity of tobacco
consumed by the person. It will detect levels 0 to 2,000ng/ml of nicotine, a
range lower than which can be determined by the urine test.
In this test, an individual should give a saliva sample,
during which a strip is soaked for twenty minutes. The saliva then reacts with
cotinine, indicating several different levels of cotinine and suggesting the
quantity of nicotine exposure.
