For recovering addict Candy Trudgett, the distance she's travelled to battle the disease can be measured in over a million steps.
The mother and addiction survivor was one of many participants in the Uniting Church's Half a Million Steps campaign - and one of the focuses of the subsequent documentary - that attempted highlight the need for a drug rehab centre in Dubbo.
"I was in with Uniting through one of the kid's programs and I heard about the walk, and I said that I wanted to do it, I was in the process of going to rehab at the time, but it was so hard to find a facility around here," Ms Trudgett said.
Ms Trudgett said a huge source of motivation was the knowledge that if the campaign was successful, no one else in her local community would have to undergo the same travels and troubles that she had in securing rehabilitation.
"I thought if I make a difference in doing this, it could really help them out too, so that was why I did the walk," Ms Trudgett said.
"I was lucky to do it, but it's a family thing, to get to rehab before, I had to use all my family, Uniting, everyone, it wasn't something I could do by myself."
One of the biggest impediments to successful rehabilitation for Ms Trudgett and others like her has been the travel involved, with a fruitful trip sometimes taking multiple days.
"The closest rehabs were in Sydney, Canberra, I was lucky enough to get into Woolongong with the help of Uniting, but that's still six hours away, I'd get in the car to Lithgow, then a train to Sydney, then if I hadn't made it in by a specific time, I'd be in a motel for that night, then into rehab the next day," Ms Trudgett said.
Ms Trudgett says she's optimistic that things will change throughout the region now that a rehab facility has been funded as part of the state government's 2020 budget, calling her experiences 'life-changing'.
"It took me that long to get there, I kept relapsing, relapsing, relapsing because I didn't have the opportunity to go to a rehab centre and when I finally got the opportunity to go there, it was life-changing," Ms Trudgett said.
She's also hopeful that having an easily accessible rehab centre will assist families that have been gripped by the disease, having seen the impact it's had on her family first hand.
"I think it makes a big difference, especially in a Aboriginal community and in a large family, if one person does something, it chance everyone's outcome for the whole family, it has for my kids and if they can see their parents receiving treatment here, it'll make a big difference," Ms Trudgett said.
"When I heard about the funding, it was unbelievable, I just thought to myself; this is going to change the whole community, it's giving the opportunity for people to go to rehab and change their lives, it'll be life-changing."
