Expectations about alcohol, cocaine, and benzodiazepine abstinence following inpatient heroin withdrawal management.

BACKGROUND AND

OBJECTIVES

Polysubstance use is associated with relapse and poor treatment outcomes among people dependent on heroin. Despite the high prevalence of polysubstance use among patients detoxifying from heroin, little is known about patients' expectations to abstain or use non-opiate substances. The current study examined factors associated with expectations about abstaining from alcohol, cocaine, and benzodiazepines (BZDs) following heroin withdrawal management.

METHODS

Between May and December of 2015, we surveyed 417 patients (71.9% male, 31.7 [±8.39] mean years old) initiating short-term inpatient heroin withdrawal management who reported alcohol, cocaine, or BZD use in the past 30 days. We used logistic regression to evaluate the adjusted associations of background characteristics with expectations about using each substance following discharge.

RESULTS

Approximately half of respondents reported past month alcohol (52%), cocaine (47.0%), or BZD (47.0%) use, and 25.9% reported using all three substances. Approximately half of those reporting drinking, 6.6% reporting cocaine use, and 27% of reporting BZD use expected to abstain from using that substance following heroin withdrawal. Prior opioid withdrawal was associated with a lower likelihood of expecting to stop using alcohol and BZDs, and more days of BZD use was associated with a greater likelihood of expecting to abstain from BZDs following discharge.

CONCLUSION

Persons with opioid use disorder often do not expect to stop using other substances following withdrawal management, with very few planning cocaine cessation.

SCIENTIFIC SIGNIFICANCE: Inpatient heroin withdrawal programs need to address and educate patients about how polysubstance use complicates recovery from heroin use. (Am J Addict 2019;28:36-42).
