Cross-Addiction
The development of an addiction to a different substance while in recovery from another addiction.
Full Definition
Cross-addiction refers to the phenomenon where an individual recovering from one substance use disorder develops a new addiction to a different substance. This occurs because the underlying neurobiological mechanisms of addiction remain active, making the person vulnerable to developing dependencies on other substances. It is a significant concern in addiction treatment and requires careful monitoring, particularly when prescribing medications that have abuse potential. The term is distinct from polysubstance use, which involves simultaneous use of multiple substances.
Usage
Usage note: Often confused with cross-tolerance; cross-addiction involves developing a new addiction, while cross-tolerance refers to reduced response to substances with similar mechanisms.
