A clear understanding of individual differences in these sub- jective changes can help researchers investigate the etiology of substance abuse. Links between subjective and neurological changes during intoxication also reveal valuable information about the brain mechanisms involved in alterations of consciousness. In addition, frank discussions of these changes in mood, sensations, and consciousness can help substance abusers sort the pros and cons of their drug con- sumption in therapeutic ways. Nevertheless, researchers and clinicians familiar with drugs often do not know the best way to describe or quantify their subjective effects. At least a third of Americans have used an illicit drug at least once. Drugs attract considerable attention in science, legislation, and the media. Nevertheless, people develop their attitudes about drugs and drug users based on limited information. Government policies form without a complete picture of the intoxication experience, too. Research- ers often find themselves divided into camps based on the drug they study most often (e.g., the Research Society on Alcoholism), limiting their ability to benefit from important work done on other drugs. A thorough and accessible review of the subjective effects of drugs and the dominant theories behind these effects will help inform read- ers about the experience of intoxication and help researchers learn from studies in other disciplines. I sincerely hope that readers will finish this book with a clear sense of the theories and techniques behind the investigations of intoxication and how subjective experiences relate to addictive potential. This work should help people make educated vi PREFACE decisions about drug use. It will also help researchers identify ideal ways to assess a drug’s subjective effects. In addition, clinicians may understand their substance-abusing cli- ents better once they gain insight into the intoxication that they seek. The chapters here reveal that each drug of abuse has its own unique properties, creating novel sensations, thoughts, emotions, and experi- ences. In addition, these changes in subjective states appear to moti- vate consumption in a way that may help explain problematic use. In addition, the final chapter shows an alternative technique (neuro- feedback) that can create comparable changes in subjective state. Each chapter describes the relevant research and explains its limitations. These concise descriptions of select studies will also help readers un- derstand the complex interaction of societal, biological, social, and psychological factors in the creation of altered states of consciousness.
