Dennis Quaid is opening up like never before about his battle with cocaine addiction.
In an interview with Megyn Kelly that aired on Monday, the 64-year-old actor shares how his past drug addiction has affected his life.
"I grew up in the '60s and the 7'0s and there was a completely different attitude about [drugs] back then," Quaid says on Megyn Kelly Today. "It was even in some movie budgets. I kept roaring on."
Quaid also reveals that he "was basically doing cocaine pretty much on a daily basis during the 80s."
"I spent many, many a night screaming at God to please take this away from me. [I said], 'I'll never do it again because I've only got an hour before I have to be at work,'" Quaid says. "At about four o'clock in the afternoon I would go, 'That's not so bad.'"
The turning point for the Parent Trap star was an out-of-body experience of sorts. "I had what I call a 'white light experience' where I saw myself either dead or losing everything that meant anything to me," he recalls.
