In an interview with W magazine, the West Wing writer insisted that he never hit rock bottom during his days of addiction and that he did not believe that attending rehab would help him to recover.
"I had what they call a 'high bottom'. My life didn't fall apart before I got into rehab. I didn't lose my job or run over a kid or injure anyone when I was high," he explained.
"But the hardest thing I do every day is not take cocaine. You don't get cured of addiction - you're just in remission."
He added: "I had no intention of rehab working. I just thought it would be good to put 28 days between me and drugs. There were fortune cookie sayings on the walls at Hazelden, and I'm not susceptible to those things. But I've never seen anything work as well."
