What is a conversion lab primarily used for?

A conversion lab is primarily used for the illicit alteration of drugs from one form to another. This process often involves converting precursor chemicals into fully synthesized narcotics that may be more potent or appealing for users. For example, it could involve transforming powders into solid forms for more efficient trafficking or use. Understanding the function of a conversion lab is critical in the context of drug enforcement and public safety, as it highlights the methods utilized by drug manufacturers to circumvent legal standards and control substances.

In contrast, the other options relate to different activities: the storage of illegal firearms, legal drug manufacturing, and the disposal of hazardous materials do not accurately describe the primary activities conducted in a conversion lab, which specifically focuses on altering the chemical state of drugs.
