The role of marijuana in homicide

In this paper we examine the relationship between marijuana use and homicide. Data derive from interviews with 268 individuals incarcerated in New York State correctional facilities for homicides that occurred in 1984. We found that in terms of lifetime use, marijuana was the most commonly used illicit drug in this sample; that about one-third of respondents who had ever used marijuana used the drug in the 24-hour period before the homicide; and that almost three-quarters of those respondents were experiencing some type of effect from the drug when the homicide occurred. A total of 18 respondents (7% of the total sample) said that the homicide was related to their marijuana use. We examine the reasons these respondents gave for this relationship and the other substances they reported using at the time of the homicide. We also demonstrate that from the perspective of a conceptual framework that specifies the ways that drugs and violence may be linked, there are various nuances in the ways that marijuana and homicide are related. We discuss the implications and limitations of using self-report data from perpetrators of violence for our understanding of the drugs-violence connection.
