Measuring the Reinforcing Strength of Abused Drugs

McLean Hospital/Harvard Medical School, 115 Mill St. Belmont, MA 02478

Animal models for human diseases are highly valued for their utility in developing new therapies. Animals have long provided suitable platforms for the development of innovative surgical procedures and for the study of disease states that are relatively easy to produce in otherwise healthy animals, such as diabetes or hypertension. Increasingly, new strains of animals susceptible to common human illnesses are being introduced into medical research, promising new inroads into the treatment of a variety of organic disorders. Despite these advances in model development, psychiatric disorders, by and large, remain among the hardest to induce experimentally, and the search for reasonable animal procedures to study diseases of the mind is an ongoing challenge for experimental biologists. An exception to this limitation, however, comes in the study of drug abuse. Major developments in this area of research over the last several decades have steadily advanced our ability to identify pharmacological, genetic, and environmental determinants that contribute to the development of drug dependence and addictive behavior.
