St. Martin Academy – Investigations (Week 9) Practice Test

The idea behind this question is that certain chemical precursors used to manufacture illegal drugs are tightly regulated, with a specific possession limit to deter stockpiling while still allowing legitimate, licensed uses. Ephedrine, pseudoephedrine, and phenylpropanolamine are such precursors, so the law sets a threshold: possessing these substances without the proper license beyond that amount is unlawful.

Twelve grams is the established limit in this context. Possessing up to that amount may be permissible under proper licensing or legitimate use, but having twelve grams or more without the necessary authorization triggers unlawful possession charges. This threshold helps authorities distinguish everyday, legitimate handling from quantities that raise red flags for illicit production.

Other listed amounts don’t fit the defined limit because they are either below or above the official threshold. The key point to remember is that twelve grams is the cutoff used to determine unlawful possession of these precursor chemicals.
