Scientists are calling for more research into effects of cannabis on cancer cells after one teenage boy was given marijuana by his mom and survived a terminal diagnosis.


Callie Blackwell stated that she decided she would give marijuana to Deryn, her son suffering from an aggressive and rare form of leukemia so that she can ease his anxiety and pain as he was dying in hospice.

After being unsuccessful after requesting from doctors a legal prescription painkiller that was cannabis-based, Blackwell along with Simon, her husband, met with a drug dealer at a service station in order to buy marijuana themselves, which they later prepared in their homw using a pressure cooker.

“I thought: ‘what have I got to lose? He’s dying anyway’. The effects of it blew my mind. It wasn’t what I expected,” Blackwell said to ITV’s show This Morning.

Blackwell stated that she expected the 14 year old boy, who previously underwent multiple cycles of chemo and radio-theraphy since he was diagnosed at age 10, to pass away when his doctors said there was nothing else that they could do.


Deryn, now 17, recovered gradually and now studies catering and works part time as a chef.

Wai Liu, one of the senior cancer research fellows in St George’s University of London, led research on potential anti-cancer characteristics of cannabis chemicals such as tetrahydrocannabinol (THC) and cannabidiol (CBD).

“I try and separate the science from clinical studies from anecdotal evidence, but there are certain compounds in cannabis, namely CBD and THC, which in a laboratory are anti-cancer in effect,” he stated.

“There’s no two ways about it. What it does to certain cancer cells is precisely the same thing as drug companies are trying to develop.

“But the difficulty is always translating what we see in clinical and animal studies into what we see in humans.”

“There’s something in it worth exploring, and that’s what a number of scientists are trying to do.”
