In brief: Weeks

Chemcal pneumonia ( or pneumonitis) causes irritation to the cells in the lung.
.generally not an actual pneumonia like that caused by bacteria. Aspiration (from out stomachs) is most common. It can take days to weeks to resolve. Remember that the cells lining the lung have been damaged and are trying to heal.
