"I am on a drug, it's called Charlie Sheen," The Hollywood Reporter said the actor tells ABC in an interview recorded at his Los Angeles home this weekend.
"I have one speed, one gear, Go!...I dare you to keep up with me."
The Reporter said parts of the talk will air Monday and Tuesday on "Good Morning America" and the entire interview at 10 p.m. Tuesday on a special edition of "20/20."
"There's some wrongs to be righted and stories to tell. But people need to hear my side of it," he adds.
CBS put "Two and a Half Men" on hiatus after Sheen, 45, entered rehab in January. On Thursday, it canceled the remainder of the season after a tirade against series co-creator Chuck Lorre on a radio program.
In the ABC interview, Sheen repeats his defense of using Lorre's Hebrew name, Chaim Levine, saying it is no more anti-Semitic than others referring to him by his real name, Carlos Estevez, is anti-Hispanic.
