A Playboy model battling a terminal brain cancer claims using medicinal marijuana has shrunk her tumour - and she hopes to be free of the disease in less than three months' time.
Kerri Parker, 34, from Norwich, says her recent scans reveal she's 'shrunk' half of her cancer and she feels her brain is the 'best it's ever been'.
The former Ms Europe and Miss UK is now preparing to jet to the Bahamas in two weeks' time to compete in Ms World, which she previously thought would be her last ever pageant.
Having lost two stone and dropped to a UK size zero in a month while the cannabis 'purged' her body of cancer, Kerri said she's having to munch on a McDonalds a day to gain weight to fit into her size six outfits.

She told FEMAIL: 'I thought brain cancer would kill me, but now it's not going to. Now I finally have a life – Ms World's not my last pageant.
'I've proven them all wrong; doctors here told me cannabis doesn't cure cancer and that it'll kill me, they actually told me it would make it worse and that it only works in kids.
'They scared me so much I was ready to sign my life and career away to have chemo and radiotherapy, but not now.
'If I can shrink half my brain of cancer, I'll shrink the other half. I'll shrink it down so there's not a single cell left that can ever replicate.'
Kerri, who used to spend her time partying at Hugh Hefner's Playboy mansion in LA and has a black belt in martial arts, was first diagnosed with brain cancer in 2013, and underwent life-saving surgery to have the tumour removed.

But in September last year the qualified stunt artist was told her cancer had returned, with doctors urging her to have chemotherapy and radiotherapy.
According to Cancer Research UK, there isn't enough reliable evidence yet to prove that any form of cannabis can effectively treat cancer in patients - including hemp oil, cannabis oil or the active chemicals found within the cannabis plant (cannabinoids).
But Kerri refused traditional treatment in favour of using cannabis oil from the US and changing her diet, as she was put off by the 'horrible' side effects and couldn't face losing her hair.
She said a recent CT scan showed 'visible shrinkage' since using the drug, and rather than have chemo and radiotherapy in September, she has opted for another scan in three months' time instead.
'It's a visible difference, it's only now showing in half of my brain when before it was nearly three quarters,' she explained.

Prior to her cancer, Kerri used to spend her time partying at Hugh Hefner's Playboy mansion in LA (pictured with him in 2012)
'Specialists in America are telling me it's shrunk. The reality is, I just cured terminal cancer, I'm actually going to give myself a life.
'It's disgusting that they're keeping it from people over here, I've lost people to cancer and I didn't need to.'
Kerri said the way the Rick Simpson cannabis oil (RSO) - which contains high levels of tetrahydrocannabinol (THC) - has eased her symptoms is 'incredible'.
'Doctors in America said I should have seizures because of how much cancer is in my brain, but they said the cannabis would have prevented that,' she explained.
'I've enjoyed quality of life. I still have a driving licence - I would have lost it if I'd had a seizure.
