PREFACE
It is hoped that this book will help employers and employees comply
with the Drug-Free Workplace Act as well as to help in stemming the
tide of drug abuse sweeping the nation at this time.
Our appreciation is expressed to many people —Jon Lewis of Lewis
Publishers, the editors at CRC Press, especially Helen Linna, as well as
the students we tested this material on.
Both of us would like to express deep appreciation for the under­
standing of the ladies in our lives, Renee Scudder and Cecilia Son-Hee
Langford, during the many hours in front of the word processor away
from them. This book is dedicated to them.
To all others who have helped us in this endeavor, thank you.
Any errors, omissions, and other mistakes belong to us.
