Primary heroin users + drug-free treatment: an equation for success?

This study of persons referred to publicly funded drug-free substance abuse treatment in Washington State compares 122 primary heroin users (those specifying heroin as a drug of choice) with 532 persons who preferred other substances. Information on treatment entry and completion was obtained through review of client charts at the referral agency. Follow-up interviews with 587 participants provided self-reports of substance use during a 90-day period 3-6 months following removal from the treatment waitlist. Primary heroin users were significantly less likely than others to enter the treatment programs to which they were referred. Among treatment entrants, primary heroin users were somewhat less likely than other users to complete inpatient programs but no less likely to complete outpatient programs. The heroin preference group reported less abstinence and greater frequency of use during the follow-up period than did other users, patterns that almost entirely coincided with the lower treatment compliance in the heroin group. The authors note the importance of investigating methods for increasing treatment entry rates for opiate users who desire drug-free treatment.
