ABSTRACT
At the moment, there are no international standard methods for determining isotope ratios designed to address tobacco issues. Most of the techniques used in study of other objects of food production (which also include tobacco) involve the measurement of isotope ratios for a single element, although the reliability of the conclusions substantially increases by the use of isotope ratios of two elements (δ13C and δ18O or δ13C and δ15N). For professionals, engaged in the identification of tobacco and tobacco products, of great interest is the isotopic analysis aimed at clarifying the origin of plant products in the same way as is done in the case of wine [5] (for example, by correlation of the values of δ13C of alcohol and δ18O of water in samples).
