Most existing research on the relationship between drug use and street
crime relates to heroin users and thus predates the widespread availa
bility of crack-cocaine; social science studies of crime among crack u
sers are few in number and focus on a limited set of offense types. Th
is article reports findings from interviews with 387 adult crack users
in Miami, Florida, regarding their drug use and criminal histories an
d their current involvement in a broad range of criminal activities. M
any significant differences are noted between the street and treatment
subsamples, particularly an earlier drug and crime initiation and a m
ore exclusive focus on one crime type - retail drug sales - among stre
et respondents. Gender differences are markedly smaller, especially in
the street sample. Comparisons are also made between the street sampl
e and a similar sample of heroin users interviewed in Miami some ten y
ears earlier.
