Illicit use of clonidine in opiate-abusing pregnant women.

To examine prevalence rates and psychosocial correlates of clonidine use in a sample of opiate-dependent pregnant women.Clonidine use was assessed in 90 treatment-seeking, pregnant, opiate-abusing women using both self-report and urinalysis toxicology. Clonidine-positive and -negative subjects were compared for selected demographic, substance use, and psychosocial measures.One-third of the sample was clonidine-positive. Urinalysis identified 26 clonidine-positive subjects, whereas self-report detected only six cases. Logistic regression identified four predictors of clonidine use at treatment admission: recent clinical anxiety, greater severity of family or social problems, recent cocaine use, and recent drug treatment.Clonidine use is prevalent in treatment-seeking opiate abusers, particularly those with concurrent cocaine use. The abuse potential of the drug warrants further study in this high-risk population.
