Davie

Davie is at the beginning of the process, after relapsing into drug use last year.

Davie is a cocaine and heroin user who spoke about his addiction as part of the BBC Disclosure documentary One More Fix.

"I felt on top of the world if I'm being honest, because I had never had that feeling of anything doing that to me," Davie said.

Davie has also had periods in recovery when he has been doing well, taking part in stage productions and playing for Scotland in the Homeless World Cup.

"I know where I can be, I know where I can get to... but time is running out," Davie said.
