However, for him, the turning point came when his wife LaTanya Richardson and their daughter Zoe, now 34, found him passed out in their kitchen drunk and in possession of cocaine.
Recalling the moment, he said: "When I looked up, LaTanya and Zoe were standing there. The cocaine was cooked but I'd never smoked it. That was the first time LaTanya realised I was doing something that was greater than just smoking weed and drinking."
And whilst alcohol and drugs are still around him, Samuel insists his wife is not worried he will suffer a relapse.
He shared: "I hang out with people who smoke weed on the golf course, I've been in rooms with big plates of cocaine. When I was drinking nobody offered me f***ing Cristal, now I've got bottles of it in my house that people keep giving me. My wife doesn't worry about me opening those bottles."
