In an upcoming interview with ABC's Diane Sawyer, Michael and his eldest son, Cameron Douglas, are candid about the 40-year-old actor's past issues with drugs.
"I did not think you were going to make it," Michael tells his son in a preview clip of the interview. "You were either going to kill somebody or you were going to get killed."
While Cameron says that he doesn't know how close he came to hurting someone else, he does detail shooting cocaine into his neck, his experiences with both drug dealing and smuggling. Cameron also discusses finding out about Michael's cancer diagnosis while he was serving a seven year prison sentence for possession of heroin, selling methamphetamine and smuggling drugs into prison.
"So much pain and suffering," says Cameron -- whose memoir, Long Way Home, will be released on Oct. 22. "... I reached a point where there was nothing that could be done."
As for whether his successful outcome is a miracle, Cameron admits, "I like the sound of that word."
Michael previously spoke about Cameron's past in a July 2018 interview with Radio Times.
"My son’s struggle was a nightmare," he said at the time. "It was stressful for all involved, very painful and difficult. I’m happy to say he’s in wonderful shape now."
