Handbook of Cannabis and Related Pathologies: Biology, Pharmacology, Diagnosis, and Treatment is the first book to take an interdisciplinary approach to the understanding of cannabis use and misuse. Recent worldwide trends toward decriminalizing marijuana for medical use have increased legal use of the drug and recreational use remains high, making cannabis one of the most commonly used drugs. Cannabis has a wide range of adverse neurological effects, and use and abuse can lead to physical, social, and psychopathological issues that are multifarious and complex. Effective understanding and treatment requires knowledge of the drug's effects from across scientific disciplines. This book provides an overview of the biological and pharmacological components of the cannabis plant, outlines its neurological, social, and psychopathological effects, assists in the diagnosis and screening for use and dependency, and aids researchers in developing effective treatments for cannabis-related issues and disorders. Fully illustrated, with contributions from internationally recognized experts, it is the go-to resource for neuroscientists, pharmacologists, pathologists, public-health workers, and any other researcher who needs an in-depth and cross-disciplinary understanding of cannabis and its effects.
