The harmful effects of second hand smoke from tobacco products is widely understood to be a public health hazard. The exact temperature at which toxic chemicals like nicotine, formaldehyde, and acetone are vaporized during smoking and the volatilization of these toxic compounds in cigarettes do not always correspond directly to the vaporization temperatures of pure samples. To investigate the temperature that toxic chemicals in tobacco are released, raw tobacco, cigarettes, and cigarillos were analyzed using Thermogravimetric Analysis (TGA). Tobacco samples were heated at 30°C/min to 1000 °C and the emissions were collected in methanol. Analysis of the first derivative of the TGA curve indicated that each type of tobacco undergoes significant changes in mass over five major temperature ranges: 25-200°C, 200-300°C, 300-400°C,400-500°C, and 650-825°C. The TGA analysis of the tobacco products revealed that the Burley tobacco was most dissimilar from the others, with significant changes in TGA profiles at the 650-825°C temperature range. The analysis of the TGA data will be further analyzed using principal component analysis in R studio to explore key differences between Burley and Flue-Cured tobacco.
