This book examines the effectiveness of a unique area of patient care, cannabis use in medicine. While many American states have legalized medical marijuana, the FDA still has not approved it as a treatment due to a lack of studies to prove its validity.Countries such as Canada and Uruguay, on the other hand, have legalized cannabis. This book aids in accelerating the medical legitimacy of cannabis through comprehensive coverage of its uses, legality, pharmacology, and potential issues. Organized into three parts, the book begins with topics that function as an introduction to cannabis for medical use, such as patient assessments, the role of genetics, evidence-based therapy reviews, legal aspects, and pharmacology. Subsequent chapters then delve into the practical applications of medical cannabis use, including treatment for gastrointestinal disorders, neurological diseases, rheumatic diseases, and pain management.
