Predictors of Illicit Drug Use Among Prisoners.

BACKGROUND

The United States of America currently has the highest incarceration rate in the world, and approximately 80% of incarcerated individuals have a history of illicit drug use. Despite institutional prohibitions, drug use continues in prison, and is associated with a range of negative outcomes.

OBJECTIVES

To assess the relationship between prison drug use, duration of incarceration, and a range of covariates.

RESULTS

Most participants self-reported a history of illicit drug use (77.5%). Seven percent reportedly used drugs during the previous six months of incarceration (n = 100). Participants who had been incarcerated for more than a year were less likely than those incarcerated for longer than a year to report using drugs (OR = 0.50; 95% CI = 0.26-0.98). Participants aged 37-89 were less likely than younger prisoners to use drugs (OR = 0.39; 95% CI = 0.19-0.80). Heroin users were twice as likely as nonheroin users to use drugs (OR = 2.28; 95% CI = 1.04-5.03); crack cocaine users were also twice as likely as participants with no history of crack cocaine usage to report drug use (OR = 2.53; 95% CI = 1.13-5.69).

CONCLUSIONS

Correctional institutions should be used as a resource to offer evidence-based services to curb drug usage. Drug treatment programs for younger prisoners, heroin and crack cocaine users, and at the beginning of a prisoner's sentence should be considered for this population.
