We report a rare complication after ketamine abuse. A 26-year-old known ketamine abuser developed pneumomediastinum, extensive surgical emphysema and pneumorrhachis after ‘snorting’ ketamine. He also suffered from acute on chronic renal failure and liver function impairment due to ketamine use. His pneumomediastinum and subcutaneous emphysema resolved with conservative management. Pneumomediastinum is a well-reported complication after illicit drug use, particularly smoking ‘crack’ cocaine. This case illustrates that such complication may also occur in ketamine abuse.
