Etymology: "Polydrug" is a simple compound: the prefix "poly-", from Ancient Greek "polús" meaning "many" or "much," joined to "drug." The Greek prefix has been used in English for centuries to build words about multiplicity, such as "polygon" or "polyglot," so the new word fits a long-established pattern. The "drug" half is the more recent part of the story. English took "drug" from Old French "drogue," and its earliest senses were about dried plants and herbs used in medicine and cooking, not intoxicants. The sense of a substance that alters the body or mind came later, which means the modern meaning of "drug" is a narrowing and shift from the ordinary material of medicine. Put together, "polydrug" describes the use of several drugs at once, most often in the context of substance use or clinical treatment, where a patient or user takes more than one substance together. The term is a plain, transparent formation: its parts tell you exactly what it means, and nothing in its construction has been disguised or reshaped.
