Olivia Newton-John Talks Cancer Diagnosis, Medicinal Marijuana on 'TODAY'

Twenty-five years on from her first cancer diagnosis, Olivia Newton-John is still, in her words, "a thriver."

The singer/actress sat down with TODAY to catch up on her resurgent struggles with breast cancer that metastasized to her lower back. The pain had been so debilitating she was forced to cancel her tour that was scheduled for May and, at times, made it difficult for her to walk.

"In my mind, it was over, I'd finished with it," she told TODAY's Natalie Morales. Newton-John's first bout of cancer occurred in 1992, which motivated her to become an advocate for cancer research and eventually build the namesake Olivia Newton-John Cancer Wellness and Research Centre in 2008.

On top of chemotherapy and a holistic treatment plan, she attributed the remission of her first cancer to medicinal marijuana, which her husband (a president of a natural remedy company) grows himself. 

“People have this vision from the ’60s of people just sitting around and getting stoned,” she said. “It’s not about that. This plant is a healing plant. I think we need to change the vision of what it is because it helped me greatly and it helps with pain and inflammation.”
