Debunking the myths: the facts about cotinine

The relationship between nicotine and cotinine

Cigarettes are made up of tar, carbon monoxide, acetaldehyde, nitrosamines, nicotine and 4,000 different carcinogenic chemicals. Nicotine – a highly abused, highly toxic alkaloid found in tobacco products such as cigars, cigarettes and chewing tobacco – is metabolized into cotinine by the liver, which is then excreted in the urine. When an applicant applies for life insurance and provides a urine sample, that sample is tested for cotinine at the laboratory. If the result is positive, the applicant will be rated as a smoker during the underwriting process and receive a much higher premium than a non-smoker.

In general, cotinine can probably be detected between a few days and a week after smoking cessation. The concentration of cotinine in an applicant’s body is dependent upon several variables, including:

  • Low vs. high nicotine cigarettes
  • Time of last tobacco use
  • Amount of tobacco used
  • Hydration level of applicant
  • Individual metabolic differences

ExamOne research consistently shows that using the laboratory recommended cotinine threshold of .30 all but eliminates the possibility of a false positive test result.

“Smoker’s amnesia”

Some applicants deny their tobacco use during the life insurance application process. Cotinine testing analysis* shows that 28% of applicants (age 35+) tested positive for tobacco but said they did not smoke on the application (this is called nondisclosure). While there is nondisclosure among all age groups, rates of nondisclosure in younger applicants are higher continue to rise. Laboratory testing is the only way to discover who has “smoker’s amnesia.”

Smoking non-disclosure rates for applicants 18 to 34 years old are up from 25% in 2005 to 30% in 2015. 

Cotinine myths

You may have encountered an applicant with a positive cotinine result who said things like:

  • “I’ve never had a cigarette in my life.”
  • “I was at a concert/bar last night and everyone around me was smoking.”
  • “I smoked one cigar to celebrate my new grandchild and I have never smoked before.”

The truth is that those types of explanations do not generally hold true. Indulging in a rare cigar or being around people who smoke is most likely not going to result in a positive cotinine result. A positive cotinine test is usually the result of someone who smokes, chews tobacco or wears a nicotine patch.

There will always be myths about smoking, but a laboratory test can see through the smoke and get the real results.
