What is the limit on daily purchases of products that can be used to produce methamphetamine according to relevant legislation?

The limit on daily purchases of products that can be used to produce methamphetamine, as stated in legislation such as the Combat Methamphetamine Epidemic Act, is 3.6 grams. This restriction aims to regulate the sale of over-the-counter medications containing pseudoephedrine, a common ingredient used in the illicit manufacturing of methamphetamine. By limiting the quantity an individual can purchase within a single day, legislation seeks to curb the potential for misuse of these products, thereby reducing the risk of methamphetamine production and its associated dangers to public health and safety.

This limit is based on the importance of balancing access to legitimate medical use while simultaneously preventing the diversion of such substances for illegal activities. Other options mentioned do not reflect the regulatory framework established for these purchases, making the 3.6-gram limit the correct and relevant figure within the context of the legislation designed to combat methamphetamine production.
