The nose has a fragile blood supply which is reduced by cocaine snorting. This process is called vasoconstriction (narrowing of blood vessels). When the blood vessels constrict, the blood supply is compromised, delivering less oxygen to the tissues of the septum. With low oxygen, the septum lining begins to die. Once the lining is damaged, it can no longer support the cartilage underneath and the cartilage dies. This is called a septal perforation. Once the septum is perforated, the nose can collapse because the septum is the structural support of the nose. Once a septal perforation is present it will never heal on its own.
It is much easier to deal with septum damage if it is identified early. Medical advice should be sought at the earliest opportunity if any of the following symptoms occur: constant runny nose, discharge from the nose or frequent bleeding.
