Olivia Newton-John: 'Medicinal cannabis enhanced my quality of life'

Olivia Newton-John says reports earlier this year, that she was about to die, were hurtful.

In a touching interview on 60 Minutes this week, Olivia tells Liz Hayes what it was like to read world headlines predicting her imminent death.

.

"It was a weird feeling," she said.

"It was upsetting… you think, maybe they know something I don't."

And Olivia's daughter, 33-year-old Chloe Lattanzi said her mother's new battle with cancer had been deeply traumatising.

"I would wake up in night sweats and panic attacks and I kind of pushed it, I didn't deal with it," she tells 60 Minutes.

In her first television interview speaking of her mother's illness, Chloe said, "If anyone doesn't deserve to go through cancer, it's my mum."

From the family home in Santa Barbara, California Olivia, her husband John Easterling and her daughter Chloe, talk openly about Olivia's stage 4 cancer.

Olivia was first diagnosed with breast cancer in 1992.

Her treatment was successful and Olivia remained free of her breast cancer for nearly 21 years. But it suddenly returned in 2013.

Olivia made the decision to keep the diagnosis a secret, and thought it had once again been beaten.

But in September last year Australia's doctors discovered the cancer had returned.

"I had moments where I was concerned I may not walk again," she tells 60 Minutes.

For this special 60 Minutes report, Olivia tells Liz Hayes that despite her latest diagnosis she was "getting strong again" and that her quality of life had been greatly enhanced by medicinal cannabis, grown for her by her husband John.

Olivia and John are strong believers in the power of plants particularly cannabis.

"I really believe the cannabis has made a huge difference," says Olivia.

"I'm confident," John concurs.

Olivia, John and Chloe are now cannabis converts, and now want medicinal cannabis legalised as an alternative treatment in Australia.
