DOGS IN DRUG DETECTION: An entry from Macmillan Reference USA's Encyclopedia of Drugs, Alcohol and Addictive Behavior

This second edition of the “Encyclopedia of Drugs, Alcohol, and Addictive Behavior” reflects changes in the attitudes about, use, and knowledge of drugs and alcohol since the first edition published in 1995. These changes include the decrease of crack cocaine use and resurgence of heroin use; changes in laws dealing with drug use (on both the state and national levels), and new discoveries leading to a better understanding of how drugs work and what makes them addictive. More than 700 articles, written for both the student and layperson, cover the social, medical and political issues related to drugs and alcohol, as well exploring and explaining types of addiction.
