Do strong-smelling substances such as gasoline, oil, and nail polish break one's fast, and how can addiction to these substances be overcome?

Inhaling substances that only have an odor does not invalidate the fast. However, if a substance has particles that enter the body cavity, like smoke, it invalidates the fast. As for the ruling on inhaling these substances, if it is harmful, then it is forbidden. To overcome this, one must seek Allah's help, strive in supplication, struggle against oneself, and be sincere in the desire to get rid of the matter.
