Joy Smith was told she would have six weeks to live when she was diagnosed with an inoperable and incurable cancer in August 2016.
The survivor recounted how she discovered the stomach and bowel cancer and afterwards went to the pub to process the news with her friends.
Joy, 52, went on to explain to This Morning hosts, Phillip Schofield and Holly Willoughby, that she turned to cannabis oil after reading about an american cancer patient who made a full recovery after using the product.
She said: “I was told it was inoperable and chemo might buy me time and hopefully they would get me eating before I died.”
Once she tried the product – which is illegal in this country – she noted feeling “giggly” and not aggressive.
Joy pays £250 for five millilitres which she says lasts her a couple of months.
What’s more, when she went to the hospital to have her next update and was stunned by the result.
Joy revealed: “I hit the oil every night and I was playing with it and I didn’t know if it would work.
“My next scan [came] and the results were astounding. It’s all gone [apart from] a little bit left in my gastric stomach.”
Holly, 37, could be heard saying, “My God!” in disbelief.
The presenter then demanded to know why it is illegal in this country when it was having such a profound effect on Joy’s life.
Research consultant on cannabis consumption, Matthew Atha, reasoned the THC compound is the banned part of the oil as it is what makes the user high.
Phillip, 55, purported: “I’m assuming that curing cancer with cannabidiol will be cheaper than all the other cancer treatments?”
Matthew agreed, adding: “Some accuse big pharma of using cancer to make money.
“It causes cancer cells to commit suicide and it also prevents the level of blood supply to tissues.
“It doesn’t work for all cancers and it doesn’t work for all individuals.”
Phillip added that Joy is breaking the law by buying and owning the cannabis oil, to which she defended: “[It doesn’t bother me that I’m breaking the law].
“It’s my life. When your back’s against the wall and you’re told you have six weeks to live then you will try anything.”
Meanwhile, it seemed This Morning viewers had made up their own mind on the debate and flocked to Twitter to share their thoughts.
One wrote: “I have #CRPS The most painful chronic disease known to science. Cannabis has saved my life. I was ready to end my life bcos the pain is just too much to handle every second of every day.”
A second added: “Alcohol is legal and is addictive. Doesn’t have ANY health benefits. Cannabis could have so much health benefits. It’s all in moderation. Now the UK is leaving the EU , the government should jump on it make money and regulate cannabis properly.”
A third commented: “Crazy how this lady is ‘breaking the law’ by taking a cannabis pill that has eaten away her cancer. Legalise it.”
