Waylon Jennings' drug habit became very public knowledge on Aug. 25, 1977, when the singer got arrested at a Nashville recording studio and charged with conspiracy and possession of cocaine with intent to distribute.

The charges were eventually dropped -- Jennings was rumored to have flushed the drugs before the police could produce a warrant -- but the story led to the hit song "Don't You Think This Outlaw Bit's Done Got Outta Hand."

"We were wrapped up in our music that's why we never saw / Cars pull up, the boys get out and the room fills up with law / They came bounding through the back door in the middle of a song / They got me for possession of something that was gone, long gone," Jennings sings in the second verse.

Jennings was open and honest about his addiction in his later years, saying, "I did more drugs than anybody you ever saw in your life." At one point, he claimed he had a $1,500 a day cocaine habit that he wasn't able to kick until he went cold turkey in 1984. The heavy drug use contributed to health problems for the singer, which eventually led to his death in February 2002 at the age of 64 from complications from diabetes.
