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!

Smoking a cigarette involves a combination of physical and chemical changes. The act of lighting the cigarette and burning the tobacco involves a chemical change, producing new substances. The process of inhaling and exhaling the smoke is a physical change as it involves a change in state (from solid to gas) without altering the chemical composition of the smoke.
Origami is a physical change because it involves the folding and manipulation of paper without altering its chemical composition.
A physical change that does not produce a new substance is called a reversible change. This means the change can be undone by reversing the process, such as melting or freezing.
It's a physical change why are some people f$#@%ing stupid and saying a chemical change??
Hardness is a physical change. It does not involve a change in the chemical composition or structure of a substance, but rather a change in its physical properties such as strength or resistance to deformation.

What!?!?!?!?
The process of dry ice sublimating, or turning directly from a solid to a gas, is a physical change. No new substances are formed, just a change in the physical state of the dry ice from solid to gas.
I've had dermagraphia before and after I started smoking cigarettes. I didn't see any difference. If anything, the stress relief of a cigarette has helped calm me down after or during a bad attack or outbreak.
Camel, no filter. Lucky Strike no filter. Pretty strong stuff.
your physical health? don't be dumb.
Australia did change the legal age for smoking in 2009.
Crumple is a physical change.
