Which term best describes a storage object for controlled substances?

The term that best describes a storage object specifically designed for controlled substances is "drug paraphernalia." This term generally refers to equipment, products, and materials that are primarily intended for the use, preparation, or storage of controlled substances. In the context of health and safety regulations, items categorized as drug paraphernalia are often closely regulated due to their association with the use and distribution of drugs.

While other options may seem plausible, they don't accurately capture the specific purpose of storing controlled substances. A containment device typically refers to equipment used for holding substances to prevent leaks or spills but may not be restricted to drugs. A storage system could refer to any organized method of storing items, not limited to controlled substances. A transport container may imply a temporary holding for substances during transportation, rather than specifically serving as a long-term storage solution. Thus, “drug paraphernalia” is the most precise term for a storage object designated for controlled substances.
