What are the quantity limits on the sale of ephedrine and pseudoephedrine in Virginia?

The quantity limits for the sale of ephedrine and pseudoephedrine in Virginia adhere to regulations established to prevent misuse of these substances in the illicit production of methamphetamine. The correct choice states that individuals can purchase a maximum of 3.6 grams in one day and no more than 9 grams within a 30-day period.

These limits are grounded in both federal and state laws aimed at curbing drug trafficking and ensuring that legitimate access for medical use is not overly restricted. The daily limit allows consumers to acquire enough of these medications for legitimate health needs, while the monthly limit serves as a safeguard to prevent excessive purchases that could indicate intent to misuse the drugs. This regulatory approach helps mitigate the risks associated with these substances while still allowing access for consumers who may require them for symptoms such as nasal congestion.

The other quantities presented do not align with the established legal limits, thereby illustrating why they cannot be viewed as correct regarding Virginia's regulations.
