This book provides guidance to workplace substance management investigations.
While each sample collection for testing or analysis is the start of an investigation, it
is not always the end of it. Criminal interviewing, evidence gathering, and
presentation of evidence is a skill usually acquired after a basic training protocol.
Success from investigating comes after years of experience and application of those
skills. There are set policies, practices, processes and procedures to follow in any
investigation or project, this book provides the basic information for practitioners to
build upon in their own profession or sectors. In this case the subject area is
workplace substance management.
