Thank you for what you posted on page one, Raina. My dad has a Glioblastoma Multiforme, and is going for radiation and chemo soon. I looked into everything you've posted, and when we go to the hospital soon I am going to ask if we can try Sativex. It's not prescribed for cancers here though, so I may not be able to get it for my dad.
Only other option would be to grow a plant of the right type and then get the oil but actually, it looks like we won't have time for that, the tumour is very aggressive.
