Following yet another bender, fueled by an alleged “briefcase full of cocaine,” and a radio rant against his bosses at CBS, the struggling star's show was finally shut down for the season in February. While Sheen claimed he's clean -- and allowed a national TV news show to release test results to prove it -- and said the network would be "begging" him to come back, CBS still seemed reluctant to restart production on his popular sitcom "Two and a Half Men."
The troubled TV star entered rehab in January, three months after he was hospitalized in October 2010 after authorities found him drunk and naked at the Plaza Hotel, where he had allegedly terrorized a porn star. Such behavior is not unusual for someone high on cocaine, say experts. The illicit drug is an incredibly powerful, highly addictive stimulant that can be snorted, injected, or smoked. Sheen's alleged experience with the drug may have captured more headlines, but the National Institute on Drug Abuse estimates millions of Americans -- about 15 percent -- have tried cocaine, six percent of them by their senior year of high school. Sheen’s father, Martin, has overcome his own alcohol-fueled demons. Let’s hope his son can, too.
