I edited this book for LawTech and did a major revision for this edition. This drug identification guide includes information regarding drug paraphernalia, symptoms of influence, effects, duration, methods of ingestion, overdose symptoms, field drug testing procedures, gateway drugs, a street slang glossary and more. It also includes 208 color photos of illicit street drugs including GHB, Rohypnol, ecstasy, jimson weed and spice. It is a perfect companion for the Drug Abuse Recognition School or the DAR Instructor’s Course. As a young officer, I had the first edition in my patrol car for many years.
