Introduction: The precise estimation of epidemiologic and economic rates contributes to make better the whole process of taking decisions for the effective smoking control. In 2017 the authors published a new formula to estimate the probability for the effective demand of health services attributable to smoking. This rate is very important because show the representativeness from the smoking economic burden in the burden of sickness related to smoking. 

Objective: To check analytically the ability of the rate of probability for the effective demand of health services attributable to smoking suggested by the authors. 

Materials and methods: Was made an analytic research for the ability to use a rate to measures the probability of the effective demand of health services attributable to smoking. Were used as theoretical methods the comparative and the inductive-deductive. As empiric method was utilized the bibliographic research and the differential calculus. 

Results: The formula of probability of the effective demand of health services attributable to smoking is growing and concave front of the intensity of the tobacco consumption. 

Conclusion: The suggested rate to measure the probability of the effective demand of health services attributable to smoking is strong trustable estimating the economic burden attributable to smoking.
