Morphology

controlled + substance

The phrase is compositionally transparent: 'controlled' means regulated and 'substance' means a material, so a B1 learner who knows both words can infer it denotes a material whose possession/use is regulated (typically by law). While the specific legal/drug-classification nuance may require context, the core meaning is directly derivable from the constituents and is cross-linguistically common.

Etymology

Controlled substance comes from the image of medicines or drugs put 'under control' by the law. The word controlled shows they are closely watched or limited and substance means the drug or chemical, so the phrase means a drug 'regulated by law'.
