Some cannabinoids inhibit the growth of tumour cells in test tubes and mice, but others encourage growth. Human studies are still small and hard to come by.
There is no evidence that CBD oil can be used to treat cancer in people. CBD does show promise for the management of some cancer related symptoms, including pain and anxiety, however, more research into appropriate amounts of CBD and its effects on humans is necessary.
There is some evidence that CBD oil could be effective against some rare childhood epilepsies. But again, more data is needed before we can draw any firm conclusions. Studies also show that CBD oil could be beneficial for managing anxiety and insomnia in some people, and early research also suggests a possible use of CBD for the treatment of certain types of pain.
This is difficult to answer, as research into cannabis and the chemicals in cannabis is still in its infancy. Most of the research so far has involved work in cells and mice. THC and CBD are two of the main cannabinoids found in the cannabis plant.
Is CBD oil safe?
Relatively. The doses sold in UK health stores are generally too low to cause any serious harm. Side effects of CBD include nausea, fatigue and diarrhoea. Most importantly, it can affect certain medications and you should always check with your GP before trying CBD oil. Because CBD oil is freely available to purchase in stores, it is not as tightly regulated as medicines.
This is why research and regulated clinical trials are so important. They enable us to make informed decisions on what treatments are likely to work best based on solid evidence.
One study of cannabis users found they had a lower risk of bladder cancer, but their risk of developing prostate cancer increased.

We don’t know yet whether cannabis, or any of the chemicals in cannabis, are useful to treat cancer. But it’s an important topic to discuss. And because we believe in the power of research, we dug into the science to answer some of the top questions you might have on cannabis and its effect on cancer.
The problem with these stories is that it’s difficult to know whether you have all of the facts. It’s impossible to make any kind of judgement without knowing about the type of cancer, other treatment and the person’s medical history.
It comes in many forms: oils that are dropped under the tongue, roll-ons that are applied to the skin and even solutions for vaping. Some producers extract CBD oil and add it into foods to create edible products.
Have any products using CBD-oil been approved by the FDA to treat anything?
Right now, no. There is no evidence that CBD oil can cure cancer.
