Tobacco-derived nicotine is extracted from tobacco by one of several methods. All ofthese extraction methods allow for some minor tobacco constituents to be carried intothe final product.Synthetic nicotine is chemically the same molecule as tobacco-derived nicotine;however, it is not obtained from a biological source like tobacco. Synthetic nicotine isproduced in a manufacturing facility through a series of chemical reactions, which occurin a controlled environment. This resulting synthetic nicotine does not contain the sametrace levels of tobacco constituents, which are found in tobacco-derived nicotine.Importantly, whether tobacco-derived or synthetic, both forms of nicotine have the samechemical and physical properties.
