This well meaning book provides good basic information about a select group of “designer drugs” including china white (fentanyl), crack, mdma, MPTP, crystal meth, and PCP. It has interesting and diverse quotes from interviews with a wide range of characters including experienced users, police, chemists, physicians and researchers. The chosen audience is those outside the entheogen communities… with an angle on some of the problems these substances can cause, but in all the book is reasonably fair and accurate.
