It's every parent's worst nightmare. There have have been more and more deaths from drug overdoses in recent years – just like my son Daniel who died at a music festival in January 2012.

My world fell apart when police arrived at my door to tell me my boy had died at a festival. There's no other word to describe it but horror.

What devastates me further is knowing we could stop this madness. My son made a mistake in taking a drug. It wasn't what he thought it was, and it killed him.

Doctors and experts are saying Australian festivals need to urgently introduce pill testing services to stop more deaths.

They're common in UK and other countries. Pill testing services tell people exactly what substance they would be about to take – and it's helping stop deaths. The Queensland Government has started pill testing, the ACT Government has too, but the other states are dragging their heels and too many kids are dying.

I can't get my son back but I want to make sure no-one else has to go through the hell of losing their child to a mistake like I did.

I'm pleading with you – please help me stop people dying from drug overdoses. Introduce pill testing services now.
