Cannabis is the Human Companion Plant was born out of the urgent need to publish an introductory guide-line as to how the recently discovered human Endocannabinoid System (ECS) works, and the truth about the importance of the Cannabis plant to our health. As the writer it is important for me to present this vital information in such a way that even ordinary, non-medical people will be able to read with relative ease, even if they have never heard about Cannabis before. There is no doubt that people need scientific proof, and everyone should absolutely always insist on scientific evidence. The challenge has always been to search for literature and scientific proof about the healing properties of the Cannabis plant, and then to correlate authentic scientific evidence with ancient knowledge carried down by generations of herbalists and traditional healers. Within the Cannabis plant, is a very special chemical, which can only be found in this plant; this chemical is called THC (Tetrahydrocannabinol Delta-9 THC). Our EC system requires THC and other chemicals from Cannabis to offer us excellent health, which the plant has being doing for human beings for thousands of years. Because the truth is that we have always had the EC system and we have always been in need of nutritional supplementation from the Cannabis plant in order to maintain good health. There are two major reasons why human beings need Cannabis, and why Cannabis is a real medicine. First, is that all human beings have a biological system of receptors inside our bodies that requires THC, only found in the Cannabis plant. Second, is that all human beings produce a chemical known as Anandamide that is the scientifically declared human version of THC. People use Cannabis to feel better, to eat better, to sleep better, to be pain free, to relax and to be less stressed. These are all genuine medical conditions which we know Cannabis can cure. On a spiritual level people also use Cannabis to become the type of person they feel they really want to become, because for the majority of people, Cannabis can make them feel the way they want and need to feel. It is the writer's opinion that everything about Cannabis medicine and how it heals human beings is completely dependent on the activities of the THC molecule. There is a profound connection between plants and humans, and the key to unlocking the secrets of The Human Companion Plant is and always will be THC. It is no coincidence that the acronym for the title of this book is THC Plant. We must also realize and recognize that as human beings we have practically evolved with Cannabis since the beginning of time. Cannabis is older than writing itself and it is part of us and always has been. Cannabis can enhance life and help to deliver people from disease, pain and suffering, as it has been doing for thousands of years already. Far too many people have died unnecessarily because of lack of access to Cannabis. If only we had listened earlier; so many more lives could have been saved.

I will show you how Cannabis is the most effective herbal medicine for so many different medical conditions, including mental conditions.
