This book highlights current Cannabis research: its botany, authentication, biotechnology, in vitro propagation, chemistry, cannabinoids biosynthesis, metabolomics, genomics, biomass production, quality control, and pharmacology. Cannabis sativa L. (Family: Cannabaceae) is one of the oldest sources of fiber, food and medicine. This plant has been of interest to researchers, general public and media not only due to its medicinal properties but also the controversy surrounding its illicit use. Cannabis has a long history of medicinal use in the Middle East and Asia, being first introduced as a medicine in Western Europe in the early 19th century. Due to its numerous natural constituents, Cannabis is considered a chemically complex species. It contains a unique class of terpeno-phenolic compounds (cannabinoids or phytocannabinoids), which have been extensively studied since the discovery of the chemical structure of tetrah ydrocannabinol ( 9-THC), commonly known as THC, the main constituent responsible for the plant's psychoactive effects. An additionally important cannabinoid of current interest is Cannabidiol (CBD). There has been a significant interest in CBD and CBD oil (extract of CBD rich Cannabis) over the last few years because of its reported activity as an antiepileptic agent, particularly its potential use in the treatment of intractable epilepsy in children.

Marijuana and the Cannabinoids presents a compendium of research into the botany, chemistry, and pharmacology of cannabis and the medicinal aspects of the cannabinoids. While medicinal use of Cannabis sativa L. has been reported for over 5000 years, interest in its medicinal potential and controversy surrounding its illicit use have grown exponentially since the identification of the chemical structure of the plant's active constituent (D9-THC) in 1964. This volume presents the findings of researchers on the forefront of this emerging and controversial field of study.
Chapter 1 is an overview of Cannabis and natural Cannabis medicines, while Chapter 2 focuses on the chemistry and analysis of phytocannabinoids and other Cannabis constituents. Chapter 3 discusses the potential of chemical fingerprinting of Cannabis as a means for source identification, and Chapters 4 and 5 outline the chemistry and pharmacology of cannabinoids and marijuana smoke condensate. In Chapter 6, the endocannabinoid system and the therapeutic potential of cannabinoids is presented. Chapter 7 provides technologies, development strategies, and multilevel applications for immunoassays for the detection of Cannabis abuse. In Chapter 8, mass spectrometric methods for the analysis of cannabinoids in physiological specimens are described. Chapters 9-12 discuss various consequences and adverse effects of prolonged marijuana use, including medical and health concerns and driving impairments. Chapters 13 and 14 examine postmortem considerations and the effects of cannabinoids on biopsychological, neuropsychiatric, and neurological processes.

Although primarily used today as one of the most prevalent illicit leisure drugs, the use of Cannabis sativa L., commonly referred to as marijuana, for medicinal purposes has been reported for more than 5000 years. Marijuana use has been shown to create numerous health problems, and, consequently, the expanding use beyond medical purposes into recreational use (abuse) resulted in control of the drug through international treaties. Much research has been carried out over the past few decades following the identification of the chemical structure of THC in 1964. The purpose of Marijuana and the Cannabinoids is to present in a single volume the comprehensive knowledge and experience of renowned researchers and scientists. Each chapter is written independently by an expert in his/her field of endeavor, ranging from the botany, the constituents, the chemistry and pharmacokinetics, the effects and consequences of illicit use on the human body, to the therapeutic potential of the cannabinoids.

This book serves as an introduction to graduate students and early career researchers on chemistry and botany of the cannabis plant. Cannabis botany, propagation, biotechnology, chemistry, cannabinoids and their biosynthesis, chemovars of cannabis and their identification as well as the other chemical classes of compounds known to exist in the plant are discussed. This book will build a base of knowledge on the complexity of cannabis chemistry. The Cannabis Chemistry Subdivision of the American Chemical Society recently founded in 2022 the ElSohly Award sponsored by Heidolph North America in honour of Prof. Mahmoud A. ElSohly. This award provides researchers, students, and industry professionals with resources to present their work at the Spring National Meeting of the American Chemical Society at the ElSohly Award Symposium.
