It is a chemical change, even though the cigarette is getting physically smaller. When heat is added and you inhale the chemicals, the cigarette burns and you blow out smoke which in itself is a chemical reaction that cannot be reversed. Therefore, it's purely chemical. Remember that chemical changes cannot be reversed and physical changes can. Freezing water and then melting it is an example of a physical change. The example you mentioned is a chemical change. Hope this helps! - D.F
