A 26-year-old man with a history of heavy marijuana and minimal tobacco use was found to have extensive bilateral lung bullae and interstitial fibrosis, heavily infiltrated by pigmented macrophages. These features can be associated with marijuana smoking. The differential diagnoses in this patient

The case histories are presented of four men with multiple large upper zone lung bullae but otherwise relatively preserved lung parenchyma. Each had a history of significant exposure to marijuana. In three of the four cases the tobacco smoking load had been relatively small, suggesting a possible

Cannabis use is common, controversial and its clinical toxicology is likely under-recognised. A 56-year-old man presented with disabling shortness of breath. He smoked up to 7 g cannabis daily for 25 years (maximum 63 875 g) plus large amounts of hashish oil. Chest x ray suggested giant bullae. CT

BACKGROUND If pulmonary complications of tobacco smoking are well documented, those associated with cannabis use are less known. OBJECTIVE Systematic literature review of data on pneumothorax and lung emphysema in cannabis users. UNASSIGNED Medline, on the period 1980-2018 with the following

We present the case of a 48-year-old man with an extensive cannabis smoking history who presented with pleuritic chest pain. A chest X-ray revealed multiple large, apical lung bullae with fluid levels, an appearance consistent with infection. Lung function tests showed moderate airflow obstruction

Increasing cannabis use and legalisation highlights the paucity of data we have on the safety of cannabis smoking for respiratory health. Unfortunately, concurrent use of tobacco among marijuana smokers makes it difficult to untangle individual effect of marijuana smoking. Chronic cannabis only

BACKGROUND We observed a remarkable increase in the number of young patients who presented with lung emphysema and secondary spontaneous pneumothorax (SSP) at our institution for over a period of 30 months; most of them have a common history of marijuana abuse. METHODS Retrospective case
