Olivia Newton John takes medical marijuana to ease her pain during her cancer battle.
The 'Grease' legend was diagnosed with breast cancer in May - 25 years after recovering from the life-threatening illness - and she has been taking cannabis to help her out after her herbal medicine importer husband John Easterling introduced her to its pain-relieving qualities.
She said: "I take a lot of natural herbs and healing remedies and also medicinal cannabis that's helped me a lot.
"Initially I had a lot of pain. I don't have pain now.
"I'm so lucky. I'm married to an amazing man who is a plant medicine expert."
