"I would remind Whitney that, now you know, we said, doing coke couldn’t go where we’re going, and we’re already there," Crawford says. "So, we shouldn't be doing it. And I noticed that she would go ahead and do it. She was having difficulty stopping."
In June 2016, Brown sat down with Robin Roberts for an episode of 20/20 and was candid about his and Houston's drug use. Brown said their problem with drugs was at its height during "the last few years of our marriage," which ended in 2007 after 14 years.
"It was terrible," he said. "Both of us, you know, trying to be clean, or one of us trying to be clean and the other one don't wanna be clean. It's a big struggle."
According to Brown, the marriage crumbled because of Houston's refusal to get sober and stop using drugs.
"She just wasn't ready to go that direction," Brown said.
"Our friendship was a deep friendship," she said. "In the early part of that friendship, it was physical. It was during that first summer that we met. That was the first time that our lips touched."
"It wasn't anything planned, it just happened, and it felt wonderful," she continued. "And then, not long after that, we spent the night together. That evening was the night that we touched and that just brought us closer."
