Which substance is listed as a precursor to dangerous drugs and is commonly used as a decongestant?

• A. Phenylpropanolamine
• B. Pseudoephedrine
• C. Anhydrous Ammonia
• D. Lead Acetate

Answer: (A)

Pseudoephedrine is a chemical that regulators flag as a precursor to illicit drugs, specifically methamphetamine, while also being a common decongestant in OTC medicines. Its status as a listed precursor comes from its potential use in illegal drug synthesis, which is why it’s tightly regulated, even though it remains widely used to relieve nasal congestion. Phenylpropanolamine is also a decongestant but is not treated as a listed precursor under standard regulations, and its safety concerns have led to decreased use. The other options don’t fit both parts of the description: anhydrous ammonia is an industrial chemical sometimes discussed in illicit drug contexts but not a decongestant, and lead acetate is toxic and not a decongestant or regulated precursor.
