St. Louis Author Turns to Film to Expose Overlooked Addiction Treatment

When St. Louis journalist Ben Westhoff met pharmacist Percy Menzies, it wasn’t a casual conversation—it was a challenge. That moment sparked Antagonist: How a Wonder Drug Got Sidelined, Westhoff’s debut documentary about Naltrexone, a medication that blocks opioids and curbs alcohol cravings. The film dives into Menzies’ decades-long fight to bring this overlooked treatment into the spotlight, revealing how big money interests and misconceptions have kept it on the sidelines.
