Could you get sick from breathing in gasoline?

Fumes are unhealthy: Volatile fumes from gasoline, glue, paint, etc..., are bad because they diffuse throughout the body after inhalation. The fumes one smells at a gas station are diluted by the air, so don't cause illness. If one purposely sniffs gasoline or glue, or accidentally gets too much fumes while painting inside a closet, he can get damage to the lungs, brain, etc..., especially with repeated exposures.

Yes: Yes. I have seen a patient who had gasoline spilled on her. She has breathing issues for months.
