Another person decided to share their story about how cannabis was very helpful in stopping the further growth of his tumor.
Two years ago, Kieran McCrory, 38, was given just three to five years to live but doctors have now told him his tumor has stopped growing and no other treatment is needed at this stage.
Even though it is illegal Kieran says he is going to continue using it.
Kieran is hoping to shrink the tumor with continued use of cannabis oil in the hope that he can be treated with chemotherapy if necessary, Belfast Live reported.
Kieran, from Omagh, said: “I can be optimistic about spending a good length of time on this planet with my wife and child.
“It is good to see a bit of light. Basically, the tumor has stopped in its tracks. So it’s not spread and it’s not got any bigger.”
In a moving interview with BBC Radio Ulster, Kieran added: “I just want to live. I’m not hurting anyone. I am not out there selling drugs and I don’t run a drugs factory.
“You can’t afford to put up restrictions when you’re fighting for your life. I will be taking this oil for the rest of my life. I want to get to the age of 80.”
Mr McCrory, 38, was diagnosed with a brain tumor two years ago.
In a bid to save his life, he underwent brain surgery and radiation treatment but was given a short prognosis and last year he started using cannabis oil and has witnessed a huge change in his well-being.
It remains illegal in the UK to use cannabis for medicinal purposes but two studies are currently underway for Cancer Research UK.
A spokesman for the charity said: “We know that cannabinoids, the active chemicals found in cannabis, can have a range of different effects on cancer cells grown in the lab and animal tumors.
“But at the moment there isn’t good evidence from clinical trials to prove that they can safely and effectively treat cancer in patients.
“Cancer Research UK is supporting clinical trials for treating cancer with cannabinoid-based drugs in order to gather solid data on whether they benefit people with cancer.”
Cannabis was classed outlawed as a class B drug in the UK, but a derivative is used in a spray for Multiple Sclerosis patients.
It is legal to use cannabis oil in 23 out of America’s 50 states and legislation is pending in other states.
And now Kieran is lending his voice to the campaign for medical cannabis to be legalised in the UK.
Supporters from End Our Pain have claimed the move would help more than an estimated one million people who regularly use cannabis for medical reasons.
