Which substance is specifically noted as a precursor to amphetamine, methamphetamine, or MDMA?

• A. Red Phosphorus
• B. Phenyl-2-Propanone (Phenylacetone)
• C. Pseudoephedrine
• D. Anhydrous Ammonia

Answer: (A)

Precursors are chemicals that can be transformed into controlled substances, so laws explicitly list certain substances as precursors to drugs like amphetamine, methamphetamine, or MDMA. Red phosphorus is a reagent used in a well-known illicit meth synthesis (the red phosphorus/HI reduction route). Because regulations specifically identify red phosphorus as a precursor that enables the production of methamphetamine and related drugs, it’s singled out in statutes and enforcement guidance. That explicit listing is why it’s the best answer here. Other substances may be involved in synthesis or used in production, but they aren’t described in the statutes as the specifically noted precursor in the same way.
