With a strong support group, he studied at the University of Auckland. He gained a Postgraduate Diploma in Health Science and a Postgraduate Diploma in Addictions, adding a Diploma of Counselling from Manukau Institute of Technology to complete his qualifications.
Since then he has travelled New Zealand and abroad, talking to groups as different as schools and gangs, the police and addiction services.
He has in the past 18 years become a huge asset to people wanting to find out how to deal with the world of drugs and mental health issues.
The group of listeners were fascinated and, after six hours of sharing his often-graphic experiences, sociocultural understandings and amazing scientific knowledge, they wanted to hear more.
Thorburn said his philosophy was based on the need for society to work to support addicts by providing a total list of needs.
He said it was important to give those wanting to break the drug cycle acceptance of who they were and how best to support them, like providing alternatives to drugs, such as jobs, sports and friendships.
The processes of helping those addicted varied, but he advocated walk-in centres, which were safe places where people could help by providing support.
He said his profound transformation came about by “having the right people at the right time who gave him choices he did not believe he had”.
