In September 1989, the National Institute on Drug Abuse (NIDA), with the collaboration of the National Institute of Justice (NIJ), held a technical review meeting focusing on the relationships of drugs and violence. Data from a number of NIDA and NIJ-funded research projects addressing different aspects of these relationships were presented and are included in this monograph. Following a foreword and an introduction, the articles are as follows: (1) "Violence as Regulation and Social Control in the Distribution of Crack" (Jeffrey Fagan and Ko-lin Chin); (2) "Violence Associated with Acute Cocaine Use in Patients Admitted to a Medical Emergency Department" (Steven L. Brody); (3) The Operational Styles of Crack Houses in Detroit (Tom Mieczkowski); (4) "The Crack-Violence Connection Within a Population of Hard-Core Adolescent Offenders" (James A.
