The Controlled Substance Act (CSA) primarily regulates the distribution and use of substances that have the potential for abuse, which is integral to controlling substance-related issues such as addiction and illegal trafficking. The Act classifies drugs into schedules based on their potential for abuse, accepted medical use, and safety or dependence liability. This regulation plays a key role in managing the prescribing and dispensing of these substances to prevent abuse and ensure that they are used appropriately within a medical context.

The other options do not accurately represent the focus of the CSA. For instance, while quality control of medications is important, it is not the central concern of the CSA, which specifically deals with substances prone to misuse. Additionally, the Act is not solely about the cost of controlled substances, nor does it regulate the personal use of all pharmaceuticals, as these areas fall outside its primary intent. The CSA's focus on substances with a high potential for abuse is crucial for public health and safety.
