The day-to-day criminality of heroin addicts in Baltimore--a study in the continuity of offence rates

A representative sample of 354 male heroin addicts living in the Baltimore metropolitan area was traced from onset of opiate use to time of interview to ascertain any changes in the frequency or type of offences committed during their years at risk. Five basic measures of criminality were employed: crime-day theft, crime-day violence, crime-day dealing, crime-day con games and crime-day other offences. A sixth measure -- composite crime day -- incorporated all five crime-day measures. Crime rates per year were derived from these six measures. It was found that the start of addiction was associated with a high level of criminality (255 composite crime-days per year), and that this high rate continued over numerous subsequent periods of addiction. Theft of property was the most common type of crime, followed by drug sales, other offences, con games, and violent offences. In contrast to the addiction periods, criminality decreased over successive non-addiction periods. Thus, the composite crime rate (82 composite crime-days per year) for the first non-addiction period was only 32% of the rate of the first addiction period and this lower rate of criminality decreased markedly thereafter.

The criminality of narcotic addicts

Recent research conducted by independent investigators concerning the relationship between crime and narcotic (primarily heroin) addiction has revealed a remarkable degree of consistency of findings across studies. The major conclusion supported by the majority of these studies is that narcotic addicts commit a vast amount of crime and that much of this is directly related to the need to purchase drugs. A large proportion of the crimes committed does not consist merely of drug sales or possession, but involves other criminal behaviors including serious crimes. The strongest evidence of a causal relationship between narcotic drug use and crime is derived from longitudinal studies in which the amount of crime committed during periods of active addiction far exceeds that committed during periods of nonaddiction. Much of this crime goes unreported, although addicts, under conditions of strict confidentiality, have provided information that permits realistic estimates of criminal activity. Use of this methodology has permitted the identification of different types of addicts, especially with respect to the amounts and types of crimes in which they are engaged. The implication of these findings is that although addicts as a group commit a great amount of crime, they cannot be regarded as a homogeneous class. Some addicts commit many crimes, regardless of current addiction status, whereas others commit relatively few, and these are obviously related to their need to purchase drugs. There is a discernible impact of treatment on narcotic drug use and criminality. Although the relationships between addict characteristics and treatment response have yet to be fully determined, extensive prior criminal involvement is associated with a negative outcome.

A Long-Term Program of Research on Drug Use and Crime

This paper describes the major findings emanating from a long-term research program conducted in Baltimore, Maryland, on the drugs-crime relationship. It is the compilation of experiences, studies, and findings related to the research career of David N. Nurco, D.S.W., and his colleagues. Covering a period of over 30 years, the program of research, described in the report from the personal perspective of Dr. Nurco, has moved from the study of the nature and correlates of narcotic drug use to the development of data-based interventions. Topics investigated involve many aspects of narcotic addiction, including the relationship between addiction status and crime rates; changes in addict behavior over time; individual variation among addicts in the type, frequency, and severity of crime; and an examination of the early adolescent behavior of males who eventually become narcotic addicts in contrast to that of their never-addicted peers. It concludes with a description of the programs ongoing research, principally dealing with community-based interventions.

Lifetime Criminality of Heroin Addicts in the United States

A probability-based sample of 243 addicts was selected for study from a Baltimore population of 4,069 male opiate addicts. The sample was interviewed and their criminal history was traced in detail over an 11 year risk period during which they were “on the street”. It was found that these 243 heroin addicts had committed more than 473,000 crimes. As measured by crime-days, the average addict committed over 178 offenses per year and almost 2,000 offenses during his post-onset lifetime. Although the predominant offense committed was theft (as with most populations of criminals), these addicts were also involved in a wide range of other crimes: drug sales, robbery, forgery, pimping, assault, and murder. The implications of these findings are discussed with respect to the impact of arrest and incarceration upon the lifetime criminality of these addicts. These research results provide a means for estimating the extent of criminality among heroin addicts throughout the United States. Our calculations indicate that the 450,000 heroin addicts in the United States commit more than 50,000,000 crimes per year and that their lifetime criminality exceeds 819,000,000 offenses.

Factors associated with frequency of 12-step attendance by drug abuse clients

Comparison was made of treatment clients attending Narcotics Anonymous and/or Alcoholics Anonymous meetings less than weekly (n = 41) with treatment clients attending meetings at least three times a week (n = 30). The frequent attenders (attending an average of 30.6 meetings monthly) differed from non- and infrequent attenders (attending an average of 0.4 meetings monthly) in terms of histories of greater lifetime drug use, more arrests and treatment experiences, and an earlier age of first use of alcohol. Although the frequent attender was also older, age was not found to influence the differences found between groups. Measures of religiosity, use of community services, and support from others for recovery and psychological functioning, other than ratings of the helpfulness of 12-Step, were not differentiated among groups. The findings suggest that 12-Step groups are more likely to be selected by clients with more severe histories of drug use and criminal activity, i.e., those most in need of the support to behavior change those groups provide. The role of treatment programs in facilitating the use of 12-Step groups is discussed.

A new classification of narcotic addicts based on type and extent of criminal activity

Abstract On the basis of confidential interview data obtained from a stratified random sample of 354 narcotic addicts residing within the Baltimore metropolitan area, measures of the amount of crime they committed in each of five separate categories were derived. Moreover, crimes committed during periods of active addiction were distinguished from those committed during periods of nonaddiction. Subsequent application of numerical taxonomic methods yielded eight addict types for periods of addiction and six types for periods of nonaddiction. Although fewer crimes were committed during periods of nonaddiction, individual patterns of criminal activity tended to remain constant. Differences among types in terms of demographic and background variables were also noted. Despite the fact that wide variations in criminal activity preclude generalizations to individuals, the amount of crime committed by narcotic addicts as a class can fairly be described as staggering.

Addict careers. II. The first ten years.

The varying life-styles of narcotic addicts in Baltimore during the first decade of their addictive careers are examined with respect to the following: (1) periods of addiction, (2) transitions from addiction, (3) periods of nonaddiction. Emphasis is upon the relationship between aspects of the life-styles and the characterization of addicts according to a typology based on the concepts of opportunity and motivation to use narcotics. What emerges is a general hypothesis linking social class, associated competencies, and pattern of addiction.

Early Deviance and Related Risk Factors in the Children of Narcotic Addicts

This descriptive study examines the self-reported behaviors of 285 male and female adolescent children (ages 12-17) of narcotic addicts participating in methadone maintenance programs. These children responded to an extensive 2.5-hour interview questionnaire focusing on current and past activities, including criminal activities prior to age 12. The findings revealed that early deviance, assessed by self-report measures of both severity and variety, is related to current adolescent drug and alcohol use, association with deviant peers, a negative view of home atmosphere, and psychological symptomatology. These results are contrasted with the retrospective reports of adolescent behavior obtained from adult male narcotic addicts in a prior study of vulnerability to addiction. The comparability of study results is discussed in the context of developmental risk factors, prevention and treatment strategies, and other considerations specifically related to the development of children of narcotic addicts.

Differential contributions of family and peer factors to the etiology of narcotic addiction

This retrospective study investigated relationships among early family circumstances, peer associations, and narcotic addiction in a sample of 601 urban males. Results of logistic regression analyses indicated that the extent of deviant behavior among close friends at ages 12-14 and disruption in family structure (parental divorce/separation) prior to age 11 were significantly associated with narcotic addiction. Additional regression analyses indicated that deviant behavior among family members, as well as family disruption, experienced prior to age 11, also increased the probability of association with deviant peers and a negative home atmosphere at ages 12-14. Implications of these findings for preventive interventions and for future research are presented.

An ecological analysis of the interrelationships among drug abuse and other indices of social pathology

In a study of the interrelationships among 12 separate indices of social pathology, including drug abuse, in which census tracts were the units of analysis, moderate to high intercorrelations among all indices were observed. A subsequent components-types factor analysis revealed only a single eigenvalue greater than unity, suggesting that the interrelationships among the several indices may be most parsimoniously explained in terms of a single underlying construct-generalized social pathology. Exact factor scores on this construct were computed for each tract, and those may be viewed as estimates of the degree of social upheaval present.
