Nonsmokers exposed to typical levels of SHS have serum cotinine levels of less than 1 ng/mL, with heavy exposure to SHS producing levels in the 1–10 ng/mL range. Active smokers almost always have levels higher than 10 ng/mL and sometimes higher than 500 ng/mL (Hukkanen et al., 2005).
How much cotinine is in a cigarette?
This level of cotinine represents the maximum level of absorption per one cigarette smoked, assuming that the typical cotinine concentration of 12 ng/ml per cigarette is equivalent to the usual absorption of 1 mg of nicotine per cigarette, and that a cigarette smoker can absorb up to 3 mg of nicotine per cigarette with …

There was >99.9% agreement between the tests, and the device had 99% sensitivity [31]. The device has a very high specificity of 96%, yielding a positive result in less than 5 min when the urine cotinine concentration is 200 ng/mL.
Does apple cider vinegar get rid of nicotine?
Conclusion: These finding confirm that chronic nicotine administration causes harmful effects to the liver and suggest that ACV may be useful in combating tissue injury resulting from nicotine toxicity. Hence, the intake of ACV might suppress the toxicity and mutagenic activity of nicotine.
