The earlier you light up your cigarettes, the higher the levels of cotinine, a by-product of nicotine you’ll have in your blood, regardless of how many cigarettes you have throughout the day, say the results of a study recently published in the journal Cancer Epidemiology, Biomarkers & Prevention.
Researchers looked at 252 healthy people daily cigarette smokers, with an emphasis on their urges to smoke and when they lit up their first cigarette of the day. The researchers then measured the cotinine levels in the smokers’ blood. what they found was that that the range was extremely variable – from between 16 ng/mL (mostly among smokers who waited at least a half hour before the first cigarette) to 1180 ng/mL (mostly among smokers who lit up not long after waking).
It’s not yet understood why this happens, but researchers may now be able to use this information to work on various approaches to smoking cessation tools and techniques.
