What are drug labs commonly referred to as?

Drug labs are commonly referred to as "Clandestine Labs" because the term specifically denotes facilities that are set up covertly for the illegal production of controlled substances. The word "clandestine" implies secrecy and concealment, which perfectly encapsulates the nature of these operations. These labs often operate in hidden locations to avoid detection by law enforcement agencies, emphasizing their illegal and illicit activities.

Other terms may describe aspects of drug manufacturing but do not capture the nuance of covert operation as effectively. "Illegal establishments" is too broad and can refer to any unlawful business, whereas "underground factories" and "secret operations" can apply to a wider variety of illicit activities, not limited to drug production. Therefore, "Clandestine Labs" is the precise term used in law enforcement and drug policy discussions to identify these specific illegal operations.
