Charlie Sheen: "I Am On A Drug, It's Called Charlie Sheen"

In an interview scheduled to air on a special one hour edition of 20/20 Tuesday night, actor Charlie Sheen continues to "open up" in an interview with ABC News' Andrea Canning.

Here's a snippet of what the Two and a Half Men star has to say:

"I am on a drug. It's called Charlie Sheen. I have one speed. I have one gear. Go! I dare you to keep up with me.



There's some wrongs to be righted and some stories to tell. People need to hear my side of it."

Sheen has recently called show creator Chuck Lorre a "turd" and a "clown."

Portions of the interview will air on Good Morning America Monday and Tuesday.
