Full Extract Cannabis Oil, otherwise known as Rick Simpson Oil or RSO, has been shown to cure seven of 10 cancers. But this is excellent in that it’s another study showing the efficacy of Marijuana in fighting cancer. Cancer can not be cured by smoking or vaporizing, though if you decide to go the traditional chemotherapy route, smoked Marijuana will help with the side effects. The cure is found in the concentrated oil.
