Baldwin, brother of actors William, Stephen and Alec Baldwin, allowed "Primetime" to chart his progress through a three-month drug treatment program at Renaissance Malibu, in Malibu, Calif. He taped more than 19 video entries for "Primetime."
"I've been very thorough in my recovery, and identified where I am powerless," the 46-year-old actor said. "And I'm truly powerless over cocaine. There's no question about that in my life."
Last year, police said they found Baldwin and another man in a Santa Monica motel, along with cocaine and drug paraphernalia. Prosecutors declined to file felony charges.
"It's difficult to look into this camera," Baldwin said. "It's difficult to talk about, you know, my inadequacies, my inability to stay sober when I'm a relatively bright man and I've had a lot of great blessings and a lot of great opportunities."
Baldwin, who appeared in TV's "Homicide: Life on the Street," said he tried to "get things fixed so quickly" but has now accepted that addiction will be a part of his life.
"Fact of the matter is, I will never recover," he said. "I will just always be in recovery and stay sober, so I pray."
Baldwin said in a statement posted on Renaissance Malibu's Web site that he had tried nine other treatment centers in his battle with addiction.
