With the increasing legalization of medicinal use of cannabis, health professionals are realizing the need for a text designed specifically for clinical practitioners. To address that need, this book offers a valuable resource for cannabis education, providing general knowledge all clinicians need in order to work with patients using medicinal cannabis. Although some books exist that discuss the endocannabinoid system and the pharmacology of cannabis components, these are often much more specialized or more appropriate for a scientific researcher, rather than a clinical practitioner. This book takes an interdisciplinary approach to medicinal cannabis, examining the history, laws, science, and current clinical research on the topic. From this introductory textbook, readers will gain analytical skills useful for interpreting ongoing research and new clinical information. This book fills the gap in cannabis science for both clinical practitioners and students.
