内容説明
Drugs used for nonmedical purposes--whether obtained on the street or in the local pharmacy--today constitute a major social problem and controversial issue. In a frequently cited statement, the Federal Drug Administration has estimate that in 1962 nine billion doses of amphetamines and 854,000 pounds of barbiturates were produced the United States with about "half" of these doses finding illicit channels of distribution. A national prescription audit for 1965 indicated that 167 million prescriptions written for stimulants, sedatives, and tranquilizers were exchanged across the counter for approximately $590 million. Gallup polls taken two apart (1967, 1969) reveal a remarkable upward trend (an increase of 300-400 percent) in students using marijuana and LSD. It is impossible, however, to design reasonable policies for the social control of these drugs until a great deal more is known about their possible side effects.This book reviews existing toxicological information on drugs of abuse, defines the many areas of ignorance about their nonpsychiatric hazards, and indicates productive strategies for future research. The book grew out of a recent conference cosponsored be the Center for Studies of Narcotic and Drug Abuse of the National Institute of Mental Health and be the recently formed Environmental Mutagen Society. It discusses the possible hazards of cancer, birth defects, and genetic changes that might result from indiscriminate use of so-called street drugs, therapeutic drugs of common consumption, or by the interaction of any number of drugs with each other or with environmental pollutants such as pesticides and food additives.The book first covers the chemistry and sources of drugs of abuse of immediate social impact--marijuana, LSD, the amphetamines, barbiturates (in measure of gross abuse perhaps "the most serious single problem"), heroin, Sernyl, and STP; potential problem drugs--mescaline, Datura, and DMT; and rare drugs such as Psilocybin, Ibogaine, Harmala, and other botanicals and synthetics. Subsequent chapters discuss the epidemiology and nonbehavioral pharmacology of drugs of abuse and problems created by the practice of polypharmacy for the physician and patient as well as for the drug abuser. Examples are given of a number of drug interactions.Next, the authors consider the chronic biological hazards of drugs of abuse--carcinogenic, teratogenic, and genetic--and list certain chemical groups, some of which are present in these drugs, which are known to induce mutations. A final part of the book is devoted to methods for mutagenicity testing and provides an overview of bacterial (Drosophila), plant, and more definitive mammalian genetic approaches that should be used to identify the mutagenic properties of a drug "before" it is released for public use. Cytogenic studies, especially those dealing with LSD, are extensively reviewed, and newly established approaches such as the host-mediated and dominant lethal assays are presented. A survey of over 100 references of chromosomal damage induced by drugs of abuse (with studies of LSD predominating) reveals that evidence on the side effects of LSD and other nonpsychiatric drugs is totally inadequate. Psychiatric aspects of drug dependence and abuse and the role of the National Institute of Mental Health in drug abuse problems are discussed in appendixes.A note added in press refers to a major recent development: demonstration, in the laboratories of Dr. Marvin Legator of the Food and Drug Administration, Washington, DC, that the commonly prescribed phenothiazine tranquilizers, trifluoropromazine and cholorpromazine, are mutagenic in mammals in both the host-mediated and dominant lethal assays, and that they thus represent potential genetic hazards to man.
