In an interview with RadarOnline.com’s Senior Executive Editor Dylan Howard on Saturday, Charlie Sheen responded to his father's comments comparing addiction to cancer, getting sober and the future of "Two and a Half Men.""Sounds poetic but it's rooted in bollocks," said Charlie, responding to an interview his father Martin Sheen held with Sky News where he called "the disease of addiction" a "form of cancer."Charlie proclaimed that addiction is a choice, and that he chose to free himself from addiction a couple months ago. To prove his sobriety, Charlie agreed to two drug tests conducted by Radar. He's already passed the first test and will get the results for a second, more in-depth drug test within 24 hours.
