Abstract: Primary pneumomediastinum is the presence of air in the interstitium of the mediastinum. The exact aetiology is unclear; nevertheless, it has been reported more frequently in patients with asthma and in individuals who use recreational drugs. It is commonly preceded by a sharp rise in intrathoracic pressure as in a Valsalva-like manoeuvre. We describe a rare case of severe pneumomediastinum with a small pneumothorax related to cannabis smoking and aggravated by vigorous sexual intercourse. The patient was successfully treated conservatively due to clinical and radiological stability and the absence of secondary cause.
