Alveolar hemorrhage due to marijuana smoking using water pipe made with plastic bottle: case report and narrative review of the literature

Abstract

Introduction

We described a case of alveolar hemorrhage (AH) after marijuana smoking using a water pipe made with plastic bottle (bong) before making a narrative review of the literature.

Case report

A 19-year-old male was admitted for hemoptysis and dyspnea evolving since the previous day. He smoked marijuana ten times a day using bongs. Computed tomography scan of the chest (chest CT-scan) evidenced ground glass opacities involving upper lobes with crazy-paving pattern. Bronchoalveolar lavage (BAL) yielded fluid becoming progressively bloody suggestive of AH. Screening of drug metabolites ruled out the presence of cocaine degradation products. Treatment with prednisone was prescribed and oxygen requirements decreased rapidly. The patient accepted to stop bongs, but kept on smoking marijuana using joints. He was asymptomatic 2 months later; all ground glass opacities had vanished.

Review of the literature

Four cases described exactly the same circumstances as ours. All were young male patients containing ground glass opacities with diffuse or bilateral pattern in their chest CT-scan. The explanation suggested by the authors of these cases was the potential concomitant inhalation of acid anhydrides derived from use of heated plastic bottle. No acid anhydrides were experimentally evidenced after thermodesorption of heated polyethylene terephthalate (PET) (in which a majority of plastic bottles are made) we performed, but other compounds were. E-cigarette, or vaping, product use-associated lung injuries cases share some chest CT-scan patterns with those of AH following bong use and we tried to draw a parallel between these two latter before discussing a physiopathological hypothesis.
