Hunter Biden, the president’s son, is being tried in federal court for falsely claiming on a gun purchase application that he did not use illicit drugs. Testimony from his ex-wife and former girlfriends describe his drug-fueled temper; his search for his dealer on the streets; his large cash withdrawals from the bank.

Hallie Biden, the widow of his brother Beau who dated him during the fall of 2018 when the gun purchase took place, spoke of his erratic behavior, his possession of rocks of crack cocaine “the size of Ping-Pong balls, or bigger, maybe” and how she frantically urged him to go to rehab. She, like Mr. Biden, is in recovery.

I write about addiction for The New York Times and have spoken with countless families who have shared wrenching experiences. I’m working on an article about how the Bidens’ addiction saga is reverberating for families who are also grappling with America’s deadly addiction crisis.

To better understand evolving public views toward addiction, I would like to hear your stories. I’ll read each response and reach out if I’d like to learn more. I won’t publish any part of your response without following up and verifying your information. And I won’t share your contact information outside the Times newsroom or use it for any reason other than to get in touch with you.
