"For some of these children, it's normal in their home and for some, the drugs are just a way of getting through their day."
For the past 16 years, Davy has taken care of troubled youth in the small town of Pahiatua, population around 4000.
The veteran youth worker is now embarking on a Mental Health and Addiction Support Apprenticeship through Industry Training Organisation Careerforce, seeking to arm herself with the tools she needs to provide specialised care to the youngsters.
"One of the biggest challenges in our community and for our service is that we have become a one-stop-shop but we can't access adequate mental health services - this is why I wanted to do the qualification," she said. "I'm doing the work already."
Ms Davy, who runs the Tararua Youth Centre, said the biggest issue facing youth alongside mental health, was addiction.
"We have 14-year olds smoking P because it's easier to get than pot. We struggle with things like family violence and the normalisation of addictions."
She said the impact of P in the community was across the board.
"We've got people you'd never expect taking these drugs. When they legalised synthetics and then they decided they wanted to take it off the shelves, this centre was like a sick bay.
"We were here for days with kids trying to come off. This is where we come in."
Multiple sources in the town said dealers were giving marijuana laced with P freely to youth.
"A lot of the time it's in the tinnies... the kids are aware of it, they can spot it now.
"You've only got to walk down the street and see someone from a couple of years ago and you don't recognise them. It's the adults too...then it's the ripple effect down.
"People are losing everything."
Suicide, depression, self-harm and violence are also part of the job.
"We've lost young people to suicide yes and, things like self-harm can also become an addiction. It's a release and we've got to be here to help them, on the ground.
"There are times we call mental health; no one comes so we drive the 45 minutes to hospital with these kids."
Local police declined to comment on the issue of methamphetamine use in Pahiatua.
However, Sergeant Shane Brown said they were aware it was an issue, just as in any other rural community in New Zealand. He welcomed any information from the public on the sale and supply of drugs.
Tararua College principal Jon Ward acknowledged drug use had been an issue with some youth but said supporting students with a positive education helped them overcome this.
"We really need to give decent pathways to youth. I think there's been a real gap around supporting students in this particular area here because there haven't been those linkages with industry...but that's changing.
"The criteria...low to moderate, moderate to high, it needs to go.
"We have actually taken young people and adults over to A and E after making phone calls to Palmerston North Hospital and nobody coming.
"We've sat there for hours until they've been accessed help and, unfortunately, a lot of the time they're not put into a ward because we've managed to sit with them for six to eight hours, got them a bit calm, so of course they say well they're not actually a risk at the moment."
"We can wait weeks for referrals, and sometimes they will ring the young person, leave a message and then close the file saying no contact."
Ms Davy said care provided to those suffering from mental health issues was below par and she hoped the apprenticeship would enable her to improve this.
