This study examines 5225 out-of-treatment crack users and drug injectors dr
awn from five different geographic areas to examine selected factors associ
ated with homelessness. Of these crack users, 27% considered themselves und
omiciled, and 60% had previously entered some type of drug treatment. Logis
tic regression found that substance abusers who were married, female, and p
ersons of color were less likely to be without a home when other variables
were controlled. Trading sex for money and perceived chance of getting acqu
ired immunodeficiency syndrome (AIDS) were associated positively with homel
essness, while participating in methadone detoxification and methadone main
tenance programs seemed to offer some protection from homelessness.
