What should I ask Ben Westhoff?

I will be doing a Conversation with him, no associated public event, here is from his home page:

Ben Westhoff is an award-winning investigative journalist who writes about culture, drugs, and poverty. His books are taught around the country and have been translated into languages all over the world.

His new book Fentanyl, Inc.: How Rogue Chemists Are Creating the Deadliest Wave of the Opioid Epidemic releases September 3, 2019 in the U.S. (Grove Atlantic) and October 10, 2019 in the UK, Austrailia, and New Zealand (Scribe). Here’s more information.

His previous book Original Gangstas: Tupac Shakur, Dr. Dre, Eazy-E, Ice Cube, and the Birth of West Coast Rap has received raves from Rolling Stone and People, a starred review in Kirkus, a five-star Amazon rating, and made numerous year-end best lists. More info can be found here.

…his 2011 book on southern hip-hop, Dirty South: OutKast, Lil Wayne, Soulja Boy, and the Southern Rappers Who Reinvented Hip-Hop was a Library Journal best seller.

Here is my review of his excellent forthcoming Fentanyl, Inc.  He also has a well-acclaimed book on New York City bars and dives.  All of his work is fascinating.

So what should I ask him?
