The former Two and a Half Men star, who was fired from the show after feuding with creator Chuck Lorre, insisted that rehab is not an effective solution to his substance abuse problem.
"I don't believe in rehab anymore. It's not for me," Sheen said while appearing on Good Morning America. "It's not a one size fits all.
"We live in a country where it's always Miller Time," he continued. "It's happy hour somewhere in the world."
When asked if he consumes alcohol, Sheen responded: "Who doesn't?"
Sheen recently spoke out about his 2011 public meltdown, describing it as a "weird dream [he] couldn't wake up from".
The actor is currently promoting his new FX sitcom Anger Management, which premieres at 9pm on June 28.
