At what age can a person legally purchase Schedule V exempt products?

In Arkansas, the legal age to purchase Schedule V exempt products is 18 years old. Schedule V substances are those that have some medicinal use but are considered less risky regarding abuse potential. The law recognizes that individuals who are 18 years of age are legally considered adults and, therefore, are allowed to make certain decisions regarding the purchase and consumption of products regulated under controlled substance laws.

This age restriction is in place to ensure that individuals have reached a level of maturity regarding the responsibilities associated with purchasing and using substances that could affect their health and wellbeing. The other options present ages that do not align with the specific laws governing the purchase of Schedule V substances in Arkansas. Thus, the correct answer reflects the legislation that governs the legal responsibilities of individuals in this context.
