How did our nation's current opioid crisis come about? What steps were -- or were not -- taken as this epidemic was first being recognized? Who should ultimately be held accountable for this widespread tragedy? What policies enabled it, and who has benefitted most from those disastrous policies? On this edition of ST Medical Monday, we feature a "live onstage" interview that host John Schummann recently recorded here in Tulsa with Chris McGreal, a senior writer at The Guardian and former journalist for BBC. McGreal appeared at All Souls Unitarian Church last week in order to discuss his new book, "American Overdose: The Opioid Tragedy in Three Acts," and we taped our interview with him at that well-attended event.
