Wigmore on Cannabis is an indispensable and definitive source book for medical and legal practitioners seeking relevant information about cannabis, a drug that has been recently legalized in many jurisdictions. Well-known forensic toxicologist James G. Wigmore has abstracted, organized, and edited over 550 studies on the human forensic toxicology of tetrahydrocannabinol and other cannabinoids found in marijuana to produce a practical and highly comprehensible book for experts and lay people alike. Using accessible tables to illustrate the differences — and surprising similarities — between the medicolegal effects of alcohol and cannabis, Wigmore on Cannabis will be a valuable resource in both scientific and legal libraries.
