How much methamphetamine product can an individual acquire in a 30-day period?

In South Carolina, regulations governing the sale of methamphetamine precursor products align with federal guidelines. An individual can legally purchase up to 9 grams of products containing pseudoephedrine, which is commonly found in over-the-counter medications used for cold and allergy relief, within any 30-day period. This limitation helps control the availability of substances that can be misused for the illicit production of methamphetamine.

Choosing this specific quantity acknowledges the regulatory intent to strike a balance between allowing access for legitimate medical uses while also mitigating the risks associated with the potential for abuse. Hence, the correct answer reflects the legal framework established to regulate these substances effectively.
