A similar process can occur in the upper palate of the mouth. Palatal perforations are not as common as septal perforations, but they can occur through long-term abuse.
Respiratory problems and pulmonary damage : Snorting cocaine can cause mucous membrane damage through the sinus cavity, leading to the throat and upper respiratory system; however, smoking crack cocaine is more likely to cause serious respiratory problems . Blood vessels in the lungs constrict; alveolar walls are destroyed so oxygen does not enter the bloodstream as well; and capillaries that carry oxygen to the rest of the body can be destroyed. Chronic cough, higher risk of infections like pneumonia and tuberculosis, acute respiratory distress, asthma, and pulmonary edema are all associated with freebasing cocaine.
People who chronically abuse crack cocaine can develop “crack lung,” or eosinophilic pneumonitis. Symptoms of this condition include:
