Is smoking considered among the things that break the fast, even though it is a gas, and what is its ruling?

Smoking, in all its forms, invalidates the fast of a fasting person, because a substance enters their body cavities by their own choice. Some of it reaches the lungs, and some of it descends into the stomach. It is not like smelling roses or musk; rather, it is a tangible substance (body) that reaches the body cavities through the actions of the fasting person.
