Cannabis for kids

Sa
I just watched a short documentary from National Geographic about parents who are choosing to give their children cannabis oil (I think it's similar to an essential oil?) for it's medicinal purposes. The documentary followed three families, two of the families had a child with severe epilepsy, another family had a child with a brain tumor. All three families saw an incredible change in their kids even just days after beginning the cannabis oil. Seizures were reduced from several hundred a day to only a few a day, the children's eyes were cleared and they began to function normally. The families are convinced that cannabis is extremely healing, and they're hoping the government will allow for more long term research to be done on the topic.
My question is, what do you think? Would you ever consider giving yourself or your child cannabis oil if you were in this kind of situation?
