Ross James Davis, aged 56, died from complications of intravenous opioid use. He had severe chronic obstructive pulmonary disease exacerbated by heavy smoking, chronic pain, and opioid addiction. Despite two prior presentations to hospital with cardiorespiratory arrest from opioid overdose (most recently October 2013 requiring ventilation), he continued injecting opiates. He was found unresponsive on a couch after an evening where witnesses noted he appeared heavily sedated. Post-mortem toxicology showed morphine in the toxic/fatal range. Autopsy revealed severe pulmonary hypertension from IV drug use, empyema, emphysema, and myocarditis. Clinical lessons include the challenges of managing patients with concurrent severe lung disease and opioid addiction, the importance of recognising repeated overdose presentations as high-risk situations requiring intensive harm reduction and addiction services engagement, and the potential for impaired drug tolerance in the context of organ damage.
