Actor Christopher Lloyd has detailed his decades-long battle with cocaine and alcohol addiction in his new memoir, "In My Own Time." The 88-year-old star revealed that his substance use became deeply ingrained in his life before he ultimately sought treatment and achieved sobriety.

Lloyd recounts in the book that his cocaine use began after a woman at a Los Angeles nightclub offered him the drug. "She meant cocaine, which at that point I had never tried," Lloyd wrote. "I hadn’t been out looking for it, but I said all right. We went out to her car and did a couple of lines. That was all it took. I was hooked almost immediately. I loved it, and that was where my cocaine abuse began."

He added that within a couple of years of arriving in Los Angeles, cocaine, alcohol, and marijuana had become a significant part of his life. "It wasn’t just the occasional weekend indulgence. It got entrenched," he wrote.

Lloyd explained that he made a conscious effort to remain sober while working, refraining from being under the influence on set. "I never went onstage or in front of a camera high or drunk, because I knew I would lose control of myself," he said. "But once the curtain came down or the director said, ‘That’s a wrap,’ all bets were off."

His alcohol consumption also became problematic. During a medical appointment, a nurse informed him he was an alcoholic after he disclosed drinking two to three drinks daily. "It stunned me, because I didn’t think what I was doing was a problem," Lloyd wrote.

He recognized that his substance abuse was beginning to impact both his career and personal life. "I was recognizing that I had a problem, and if I couldn’t yet appreciate that I was putting my life at stake, I could at least see that it was endangering my career," he stated. "I had gotten into these things pretty seriously and I needed help to get under control and get out of it."

In 1993, Lloyd entered a treatment facility in Arizona. However, he initially resisted the program, escaping the facility and sustaining injuries from running into a barbed-wire fence. He was eventually admitted to Sierra Tucson, where he stayed for five weeks. Despite this, he experienced relapses in the years that followed.

Lloyd found comfort in attending a private 12-step meeting for high-profile men, where he felt able to discuss his addiction openly. "Some years later, on April 1, I got sober for what turned out to be the last time," he wrote.

During a conversation with his "Back to the Future" co-star Michael J. Fox, Lloyd acknowledged his past struggles. Fox, who has also been open about his own recovery, asked Lloyd if sharing his addiction in the memoir was difficult. "Yeah. I had a problem," Lloyd responded. "Well, you recovered. We’re both in recovery," Fox replied.
