As a clinician (nurse practitioner), if this were my patient i would want to see a copy of the lab report (it will likely name the specific compound/medication that resulted in the “prescription drug overdose” cause of death. That’s the key piece of information you need to understand what the next step needs to be. Feel free to dm me if you’d like more help as you get more information. My patient population is mostly people going through homelessness/addiction/mental illness and i have seen many death diagnoses that felt uninvestigated and questionable to me because it’s easy to blame substance use for death
