Harmful Components in Tobacco Smoke and Factors Affecting Their Content

M. Docheva, Y. Kochev, M. Kasheva and H. Bozukov


The aim of this study was to determine the influence of the smoking regime on thе content of tar, nicotine and CO, and to establish the decreasing content of tar, nicotine and CO with increasing the filter ventilation by 10, 20, and 30 %. The smoking regime and filter ventilation were investigated as the factors influencing the components of tobacco smoke. The intensive smoking regimes increased the content of tar, nicotine, and CO between 57 and 164 %. The filter ventilation was the other most significant factor on the increased content of components in tobacco smoke. Tar, nicotine and CO in non-ventilation cigarettes increased between 36 and 92 % compared to the same cigarettes with 30 % ventilation. The greatest increase was observed in intensive smoking regimes and closed ventilation.
