All of us know someone who has cancer or if you are lucky you may know someone who had cancer and beat it.
There is a lot of evidence that points to the fact that some cancers may be helped or even stopped by medical cannabis. The best ratio for cancer is a 1:1 ratio (eg. 7%THC:7%CBD). It has been proven that some cancers respond better than others, but some 4th stage cancers have responded in a positive way. You can take up to a gram a day. Most 30 ml bottles contain about 5 grams of cannabis. So you need to do some math to figure out how much to take. Always start low and go slow until you build to the amount you feel is helping you. Most people get results with even 500 mg/day (0.5 grams).
Even if it does not cause your cancer to retreat, at least it greatly reduces the pain and anxiety a cancer patient might suffer. There is so much to learn about this plant and how to use it and a lot of it is found out by just experimenting with it.
The THC is the part that actually appears to help kill the cancer cells and research thinks that the CBD keeps the cancer from spreading. There is so much more research to be done to know what all the benefits are and what the best way to consume (smoke, oils, edibles) might be for different types of diseases.
I know one thing for sure, if I was diagnosed with cancer or any other serious disease, I would try it and even if you want to do chemo, radiation and other treatments, it will still help your body to be less anxious, less nauseous, and you will sleep better. Sleeping properly is probably the best thing you can do to help your body heal.
