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."
Olivia will be spending Christmas with John and her daughter Chloe, and she is hoping the 31-year-old singer will tie the knot to her fiance James Driskill next year.
Speaking on 'The Today Show', she added: "I think next year they will get married. I hope they will. If they don't, that's fine and whatever they want. But I think they might do it."
In September, Olivia insisted she didn't want to be a cancer "statistic", refusing to research the numbers who have died from the disease after being diagnosed a second time.
She said: "I think that can be really depressing, and I'm not going to be one of those statistics. I'm going to be fine. I think you can live with cancer like you can live with other things if you take care of yourself.
"I think it taught me I'm stronger than I thought I was. Because even though you have a team around you and people are helping you, really in the end, it's up to you. Believe you can do it and to go through it."
