In 2006 Newshub Journalist Patrick Gowers Mother, Joan, was diagnosed with terminal lung cancer. After a painful, year-long battle, she died at just 57.
"Anyone whose lost a relative to cancer will know the amount of suffering that people go through and how harrowing that is for families as they try to deal with the pain that their loved ones are in and my family's no different," Gower said.
"It was awful to see my mum suffering."
In the documentary, Gower interviews his father, Gordon, about his mother's last days, weeks, and months when they were pumping her full of morphine to manage her pain.
"The reason for that [interview] is I want to know if cannabis could've helped my mum at that time... We didn't give her any," Gower said.
"I look back now and I wonder whether we should have."
Gower said he felt like he had failed his Mum by not giving her cannabis as a treatment option.
"I am a firm believer that medical cannabis could've helped my mum and could still help the many thousands of New Zealanders who are out there in pain right now."
