Valdez2 1 School of Social Work, University of Maryland, Baltimore, Baltimore, MD, United States 2 School of Social Work, University of Southern California, Los Angeles, CA, United States Aims: Studies indicate crack use among Latino immigrant day laborers (LIDLs) who arrived in New Orleans to work on rebuilding efforts post-Katrina. This emergence of crack use is compelling as it hasbeenpreviously found tobe lowamongLatinoswhencompared to other groups and its use has been associated with the spread of HIV and other blood borne pathogens. The aim of this study is to explore heterogeneity among LIDLs who use crack and factors associated to sub-groups of crack users. Methods: In-depth qualitative interviewswere conductedwith 52 LIDLs in NewOrleans. Participants recruited fromday labor sites were: 18 years of age or older; self-reported use of illicit drugs during the past year; arrived in New Orleans post-Katrina; and living in the New Orleans area. In-depth interviews were conducted in Spanish lasting 1–1.5h. Analysis of data consisted of defining the broad dimensions and specific variations distinguishing patterns of crack use. Results: A post-disaster context, social isolation,workers’ rights abuseswere identified as contributing factors to drug initiation and periods of daily use. Variations among crack users were seen in frequency of use (occasional users vs. frequent users), initiation of druguse (initiationofdrugspre-migrationvs. initiationofdruguser post-migration), and family ties (strong ties vs. weak ties). Conclusions: The emergence of crack use among this sub-group of Latino immigrant day laborers is particularly problematic as this population lacks access to preventative and health care services. Interventions should acknowledge variations in crack use among Latino immigrant day laborers to provide effective services for this vulnerable and high risk population.
