The Swansea-born Waterloo Road star Richard Mylan has revealed a 20-year battle with heroin addiction.
Talking to the BBC in what "could be a career-ending interview", the former Waterloo Road and The Bill star, who has been in recovery for 10 years, said he was one of a "number of many functioning professional addicts".
He decided to share his story in order to try and reduce the stigma around drug addiction. He said: "What I care about is challenging our empathy response as a society. There are so many people out there who would never ever come forward because the stigma is so great."
