Near-death experiences (NDEs) are often seen either as proof of an afterlife or as hallucinations or fabrications. After two decades of research, neither extreme view is supported. The evidence suggests NDEs are complex phenomena that cannot be dismissed as mere hallucinations or taken as straightforward evidence for life after death.
A new edition of Karch's Pathology of Drug Abuse covers the toxicology, clinical effects, and epidemiology of recreational drugs, with detailed historical introductions. Cocaine is the most common cause of drug-related death in the US according to DAWN surveys, while heroin leads in the UK. The book discusses interpretation of toxicological findings, such as post-mortem drug redistribution and the difficulty of defining fatal concentrations. It includes chapters on stimulants like khat and ephedrine, hallucinogens including MDMA and LSD, opiates, dissociative anaesthetics like ketamine and GHB, anabolic steroids, and solvent abuse. The author recommends the book for anyone dealing with substance misuse.
