Cannabis research papers are now coming out at a rate of around 4,030 a year. Most of these articles are medically relevant—many present convincing results in animal models of severe medical conditions. There is a pressing need to get this vital research into the hands of patients, families, and physicians. There is also a need to know which cannabis compounds are helpful for which conditions—something required to develop new medically relevant cannabis strains. The conditions covered include: Arthritic progression. Physical pain. Cognitive decline and other neurological conditions. Schizophrenia and other psychiatric disorders. Physical addictions. Cardiovascular conditions. 16 types of cancer. The author determines which of 9 cannabinoids and 21 cannabis terpenes are relevant for each medical condition and lists their effects. The presented research consists of facts gleaned from online peer-reviewed articles. An online supplement documents these facts using 1,400 citations and online references. The references are excluded from the book proper for more streamlined reading. The supplement is not generally accessible but may be obtained from the author by special arrangement.
