The fact sheet focuses on drug-related offenses and drug-using lifestyles. It reports results of federally sponsored surveys, including the National Household Survey on Drug Abuse, the Drug Use Forecasting Program, a survey of State and Federal prisons, and a study of homicides in the 75 most populous counties in the United States. Results reveal that arrestees often test positive for recent drug use and that incarcerated offenders are often under the influence of drugs when they commit their offenses. In addition, offenders often commit offenses to support their drug habits. Moreover, drug trafficking generates violent crime. However, the relationship between drugs and crime is difficult to specify because most crimes result from a variety of factors, the definition of drug-related varies from study to study, and offenders may exaggerate or minimize the relevance of drugs. Homicide statistics illustrate the difficulties in quantifying the drug-crime relationship. Tables and list of 6 references
