A Christchurch man has made an extraordinary turnaround from being in the grip of a drug psychosis to rapping about his life to help others and save lives.
Seven Sharp met Hunter Wilson, 31, who by the time he was in his twenties had been hooked on hard drugs.
In the grip of meth-induced psychosis last October, Hunter agreed to be admitted to hospital, and it was there that he poured his pain into lyrics.
"When I found music it's like the feeling, it's butterflies. Music is the medicine," said Hunter, who's making a comeback as rapper King Cass.
And this 'bad kid' from Christchurch has big dreams, starting with a big project - an album dedicated solely to suicide prevention.
"For me it's really wanting to spread this message of positivity is my main thing, but definitely suicide prevention and suicide awareness," he said.
Seven Sharp told how, at the age of two, Hunter had turned devilish, and for five long years, his mother, Therese Spinks, and his father had no clue why.
"He would throw tantrums for two hours and then take a breath and go for another half hour," Ms Spinks said.
He was eventually diagnosed with attention deficit hyperactivity disorder (ADHD).
His mother had her own problems with depression which had culminated with a suicide attempt.
In a happy twist, Hunter Wilson's rock bottom was his catalyst to rising up during his hospital stay.
