Martin Sheen, the father of troubled actor Charlie, has candidly spoken about his son's addictions.
In a recent interview on Desert Island Discs, the 70-year-old actor described Charlie's battle with his demons as a "rollercoaster ride".
And he said that his addiction to alcohol and drugs was "as dangerous as cancer".
Martin – himself a member of AA since the mid-Eighties – told the BBC Radio 4 show: "Charlie is dealing with the most profound problems and addiction - there's no secret, his behaviour has been an example of that.
"So if he had cancer, you know, how would we deal with him?
"Well he has another disease and it's equally as dangerous as cancer, and so we lift him up, we pray for him and be present to him and try to lead him as much as we can.
"But he's an adult and he needs a lot of help on a lot of different levels.
"He's been out there on his own for a very long time and as a family, we never get used to it.
"It’s a roller coaster ride and it's been going on for some time. So you know we deal with it, every day."
