I used this book a great deal when I was a practicum student with little knowledge about substance abuse. It provides an extensive glossary/dictionary of both medical and slang terms for thousands of entries. I strongly recommend this book for anyone who would like to develop thier understanding of substance abuse.

Glen L. Evans is the 20th/21st century Renaissance Man. He has, in the course of a long life, been a geologist, an archaeologist,a photographer,a writer,an angler, a constant observer of nature in all its aspects, and a storied teller of tales, some of them rather tall in nature. He pulls all these facets together in this book with exceptional insight and a gloriously personal writing style. Those of us who are privileged to know Glen personally have been enriched and marvelously entertained over the years by his astonishing storytelling gifts. Somehow, he has managed to transfer his oral tales to written form without losing the magic. Here are stories of his favorite mule, of birds, of Longhorns, of frogs, of people, of weather, of trees...the topics are varied and the reader's interest and involvement in the lore of Texas is guaranteed on every page.
Accompanying Glen's wonderful observations are exquisite illustrations done by his wife, Darla Evans, with great accuracy and delicacy. This is an unusual book, and one to be kept, cherished and re-read; it is also a great gift for a reading, thinking friend.
