Is cocaine use to blame for this lung condition?
John, a 22-year-old retail worker, presents to an ED around midday complaining of a sore throat, a sensation of swelling in the anterior neck and chest pain on deep inspiration.
He admits to binge drinking alcohol and nasally insufflating one-quarter of a gram of cocaine the night before, with symptom onset on waking that morning.
He denies associated coryza, cough, fever, nausea, vomiting or diarrhoea.
There is no rash or wheeze. There is no past medical history of note. John takes no regular medications and has no known allergies.
