Here is a perfect case of how cannabis is of immense benefit. The girl is not smoking it but using the oil extract so there is no damage to the lungs or bronchi. It has been proved to be non-addictive so that is of no concern. Finally the lethargic effects have proved to be quite temporary. There have been many extraordinary reports of cures using the extract and now medical science is beginning to discover and understand why.
Her father is worring unnecessarily and when you consider the alternatives his attitude could actually contribute to permanently damaging her or to her actual premature death. More people die from the effects of current cancer treatment than survive I am told. The degree of indoctrination after years of propaganda has created this resistance to what otherwise would be a kind of miracle drug in my opinion.
I guarantee you that if I am ever diagnosed with cancer of any kind I would definitely try the cannabis cure before I would allow myself to be burned and disfigured with radiation and poisoned with chemotherapy. There is just too much current science supporting its effectiveness to ignore it.
When we are talking potential death age is not relevant. Survival is all that matters. Frankly I cannot understand her biological father's attitude unless he is just totally unfamiliar with the current state of research on this herbal medication. I think that the fact that her leukemia is presently in remission is positive proof of its effectiveness even if the doctors treating her insist it is their treatments. It really doesn't matter who is right. The point is she is doing OK and surviving.
