Cannabis

A cancer patient claims to have been cured by cannabis.

Has his "cure" be verified by doctors? I don't see that in the story, so how do we know his "claim" is true.

‘I felt like the chemo was killing me and I had nothing to lose. I could not really accept I was going to die.’

He had underwent gruelling sessions of chemotherapy and radiotherapy before having surgery to remove his large bowel in March 2013, which were all unsuccessful.

So, he underwent traditional treatments of chemo and surgery, seems to me far more likely that his remission is thanks to that as opposed to thanks to marijuana.

Now, I am very much in favor of more medical research into cannabis, and favor its treatment for chemo patients, but I draw the line at vague claims in tabloid papers.

As to your links:

The active ingredient in marijuana cuts tumor growth in common lung cancer in half and significantly reduces the ability of the cancer to spread, say researchers at Harvard University who tested the chemical in both lab and mouse studies.

Mr. Hibbit was suffering from a cancer of the bowel, not lung cancer based on what the story said.

A British researcher has found that cannabinoids, a term for chemicals derived from marijuana, can kill leukemia cells, and he expects clinical trials for new medications to begin soon.

Again, wrong cancer.
