When Richard Farrell read James Frey’s “A Million Little Pieces,” he got mad. He knew immediately that Frey’s story of drug rehab was bogus, because Farrell had gone through rehab himself — and not in an upscale detox facility like Hazleton, but in the municipal program in Lowell, Massachussetts. So Farrell decided to write his own book about the experience.

Today on KTRS/St. Louis, I talked to Farrell about that memoir, “What’s Left of Us.” We discussed what drove him to become a daily heroin user, what it was like going through detox, how he kicked the habit and became a successful screenwriter and film maker (his script for “The Fighter” is about to go into production, starring Mark Wahlberg and Christian Bale).
