Pseudoephedrine is classified as which of the following?

Pseudoephedrine is classified as a precursor because it is a chemical compound that can be easily converted into other substances, particularly in the illicit production of methamphetamine. This classification is significant due to its potential to be misused in illegal drug manufacturing, which has led to various regulations surrounding the sale and distribution of products containing pseudoephedrine.

It is important to note that while pseudoephedrine does have stimulant-like effects because it can increase heart rate and blood pressure, its primary classification as a precursor highlights its role in the production of more dangerous substances rather than its effects on the body. Other classifications such as depressant, stimulant, and analgesic do not accurately encapsulate the main concern with pseudoephedrine, which is its use as a base material for illicit drug synthesis.
