This is an interesting book that does just what it says: it views alcohol as a drug with significant physiologic effects. Several chapters are devoted to the effects of ethanol given in conjunction with other drugs (barbiturates, nonbarbiturate hypnotics, tranquilizers, narcotics, caffeine, amphetamines, methanol, anticoagulants, hypoglycemic agents, and others). A final chapter discusses legislation concerning alcohol-drug combinations. This is a valuable addition to the expanding literature on the impact of alcohol in our society. Refreshingly, it stresses pharmacology and physiology and spares us another tiresome recitation of psychosociologic aspects.
