Charlie Sheen has a reason to celebrate Independence Day that has nothing to do with America.
The "Two and a Half Men" actor, 54, announced on Twitter that he's celebrating one year of quitting his smoking habit in a message he addressed to his lungs.
"dear @my lungs, it was one year ago TODAY, that i quit smoking ! hashtag - YOU'RE WELCOME !" his tweet began.

The actor's tweet also included an admission of regret for ever picking up a cigarette in the first place.
"if i could go back in time and have NEVER STARTED, i would absolutely do so ! if you are on the fence about quitting, trust me; the sooner the better ! happy 4th !" Sheen concluded along with a picture of a cigarette.
Last December, Sheen reached two years of sobriety. Months prior, he revealed on "Jay Leno's Garage" what led him to living a sober lifestyle.

“About a year and a half ago, it just hit me that I knew it was time to make a change -- and you know, it didn’t require some crazy rehab stint or a shootout with the cops. It didn’t require anything super-dramatic and crazy and front-page news," he told Leno at the time.
He previously said on ITV's "Loose Women" that his children were a big reason behind his new, clean lifestyle.

“I couldn’t get my daughter to an appointment that she had. I don’t drink and drive ever, I have never had a DUI,” Sheen said. “I was like, ‘Wow, I am not even responsible enough to be available for my children’s needs.’ The next morning I woke up and was like, ‘Today is the day.’"
