Kerry Katona has opened her own boot-camp rehab centre.
The 31-year-old TV personality - who has previously battled addiction to cocaine - believes exercise is the key to dealing with drug problems and has begun her own course to help others with their problems.
She told BBC Radio 5 Live: "I got massively lost in life. Cocaine became my best friend, my only friend. I went to boot camp and the first time I turned up there as high as a kite.
"A week-and-a-half through it, it was like coming out of a coma, the fog being lifted. Silly as this sounds, exercise changed my life. It was the first time I had a natural high."
According to the Daily Star, Kerry is keen to work with the NHS to expand the services.
Despite her being keen to help people get off drugs and back to health, Kerry also revealed recently she was desperate to get a role in 'Coronation Street'.
She said: "Imagine it, leopard print jacket, cigarette in me gob, 'All right love, lager and lime?' I'd be right at home.
"People don't realise how much acting I've done. I was in a comedy drama 'Showbands' which was only shown in Ireland and obviously there's the Iceland adverts."
