Abstract
It is very important to have objective measurements of nicotine dependence or tobacco addiction, especially in the treatment of smokers.

A noninvasive measure of nicotine dependence is the Fagerström's Tolerance Questionnaire. In our study we compared responses on the Tolerance Questionnaire of 217 smokers who participated in a treatment to stop smoking and also measurements of carbon monoxide in expired air (evaluated with a Mini Smokerlyzer EC-50).
