Charlie Sheen says he's clean of drugs and alcohol, but high on himself.
"I am on a drug. It's called Charlie Sheen. It's not available because if you try it once, you will die. Your face will melt off and your children will weep over your exploded body," the embattled "Two and a Half Men" star said in an interview with ABC News.
"I woke up and decided, you know, I've been kicked around. I've been criticized. I've been like the, 'Ah, shucks' guy with like this bitchin' rockstar life. And I'm just finally going to completely embrace it, wrap both arms around it, and love it violently. And defend it violently through violent hatred."
Sheen, 45, sat down for an interview with ABC News at his home where he was surrounded by his two girlfriends and the two sons he shares with ex-wife Brooke Mueller. The controversial actor said he wanted to respond to all his recent headline-making actions, including his public feud with his hit show's creator, Chuck Lorre, and show that he's now living a clean life.

Sheen, known as a bad boy in Hollywood, opened up about his past drug use, saying the last time he used drugs he "probably took more than anybody could survive [on]."
"I was banging seven-gram rocks and finishing them, because that's how I roll," he said. "I have one speed. I have one gear. Go."
Sheen described himself as superhuman, citing a "different constitution," "different brain" and "different heart" than normal people that allowed him to survive such extreme bouts of drug use.
"I got tiger blood, man," he said. "My brain….fires in a way that is -- I don't know, maybe not from this particular terrestrial realm."
When asked if he worries about dying from drug binges, Sheen quipped, "dying's for fools." He went on to explain his set of "rules" when he took drugs, which included avoiding certain blends that brought others down.
"There's certain blends I will not entertain because this [is] how people go down. I'm too smart to do that," he said. "I'm sorry for the guys that that happened to, but, you know, you should have read the directions before you showed up at the party."
At the end of January, Sheen voluntarily checked into a rehab facility following a brief hospitalization and partying spree. His decision to go to rehab prompted CBS Entertainment and Warner Bros. Television to put "Two and a Half Men" on an indefinite hiatus. Sheen later decided to undergo rehab at home.
Sheen said he no longer craved the feeling of being on drugs, saying it "bored the hell out of [him] after a while." Despite his track record, which includes three stints in rehab, Sheen said he was not worried about relapsing.
"I'm not going to, period, the end," he said. "I blinked and I cured my brain, that's how. Everybody has the power. …Can't is the cancer of happen. I can't do it. The Nike slogan doesn't say, 'Just Try It.' Oh, OK. Just try it. No, 'Just Do It,' man."
The sitcom star says he is now clean and sober. Sheen could not pinpoint the last time he took drugs, saying it was about six weeks or a month ago, but that it was shortly before CBS suspended production of his hit show for the rest of the season.
During the ABC News interview, Sheen offered to take a drug test to prove it.
"Give me [a] 'cop in a cup.' I call it 'cop in a cup,'" he said. "I'd love to prove this."
