Overview

Polysubstance use refers to the use of more than one substance, either simultaneously or within a short period. This is extremely common — many overdose deaths involve multiple drugs.

Dangerous Combinations

  • Opioids + benzodiazepines (dramatically increased respiratory depression risk)
  • Opioids + alcohol
  • Stimulants + depressants
  • Fentanyl + xylazine
  • Any combination involving fentanyl given its extreme potency

Treatment

Treatment must address all substances involved and may require specialized integrated treatment protocols. A thorough assessment is critical to developing an effective treatment plan.
