Drugs, Behavior, and Crime

Abstract

The difficulty of assessing the effects of mind- altering drugs on human behavior, especially conduct in real-life situations, is discussed. Problems in classification of drugs are also noted; it is emphasized that assumed drug effects are, at best, statements of probability. In considering crimes associated with drug use, it is necessary to distinguish between crimes based on drug use itself, which include all offenses for illicit acquisition, possession, and use of dangerous drugs and narcotics, and dangerous behavior resulting from use. The evidence is clearest for alcohol, revealing a distinct relationship between alcohol use and health hazard, suicide, accidents, and violence. The evidence is less clear for heroin, since most users are delinquent prior to being identified as "addicts" so that continued criminality after heroin use cannot be "caused" by narcotics. That the kind of criminality engaged in is influenced by drug use does seem a reasonable conclusion. Evidence about the degree of risk for the use of other drugs (sedatives, stimulants, hallucinogens, volatile intoxicants, and the like) and crime is absent. Generally, it appears that most Americans use drugs without major ill- effects—including occasional illicit use. Those likely to be engaged in drug use and in crime are likely to be urban slum- dwelling males, with an overrepresentation of minority groups. Such behavior is apt to be part of a life pattern of deficit and disorder.
