Question

legal restrictions apply to the purchase of pseudoephedrine because of which of the following risks?
respiratory depression
drug misuse
medication tolerance
rebound congestion

Explanation:

Pseudoephedrine is a precursor chemical that can be diverted and misused to illicitly manufacture methamphetamine, a highly addictive stimulant. This diversion and subsequent drug misuse is the primary reason for legal restrictions on its purchase. The other options (respiratory depression, medication tolerance, rebound congestion) are not the basis for legal purchasing restrictions.

Answer:

B. Drug misuse
