Ingested drugs from two or more drug categories are referred to as ______.

The term that best describes the ingestion of drugs from two or more categories is "poly drug use." This terminology specifically refers to the use of multiple substances simultaneously or consecutively, which can lead to complex interactions and effects. It illustrates a significant concern in drug abuse scenarios because the combination of different drugs can enhance or alter the effects of each substance, leading to potential overdose or other serious health risks.

Understanding poly drug use is crucial for drug recognition experts as it allows them to identify patterns of substance abuse and predict the symptoms that may arise from such combinations. This term is commonly referenced in both clinical settings and drug policy discussions, emphasizing the need for awareness around the multi-faceted nature of drug interactions.
