Sorry my comments might have offended some people. However the points I would like to make are these.
1. Although NICE have approved CBD for some circumstances, you cannot get a prescription for it and pop along to your chemist.
2. That means you have to obtain it "from the internet". So, you need to ask
a) To what pharmasutical standards is it manufactured?
b) What is it's purity?
c) Is it manufactured free from contamination?
d) What is the maximum dosage?
e) What are the side effects?
I have read reports that as it is a purely natural product it will not do you any harm. Well, so is a grapefruit and we all know it reduces the effectiveness of any chemo.
Until proper clinical trials have taken place it is impossible to know the answers to any of this. It is often the case that the law of unintended consequenses takes everyone by suprise. Anecdotal evidence is not good enough.
If having chemo, your health is stricty monitored, blood tests etc. Any anomolies are dealt with promptly because they know exactly what is going into your body. Throwing a curved ball into the mix of something you obtained from the internet whose origin and toxicity is in doubt is playing fast and loose with your life.
Of course there are some studies from America, the people are desperate for an alternative to the bankrupting cost of medication. However we are very lucky in the UK. Once again, until there are conclusive clinical trials of this product, and production becomes mainstream from sources that can be trusted, please listen to your oncologist.
