Charlie Sheen doesn't believe in rehab.

The Anger Management actor had an erratic 2011 - confessing to "banging seven-gram rocks" of crack-cocaine - but even though he successfully completed home treatment for substances and alcohol, he said rehab is not for him.

Charlie, who is now drug free but still drinks alcohol, told TV show Good Morning America, "I don't believe in rehab anymore. It's not for me. It's not for everyone. It's not a one-size-fits-all and it didn't fit me." Referring to US beer brand Miller, he added, "We live in a country where it's always Miller Time so what are you going to do? It's happy hour somewhere in the world."

Charlie does regret some of his outbursts, many of which were personal and directed at certain people, including Two and a Half Men creator Chuck Lorre, and lost him his multi-million dollar job starring in the show.
