What regulation limits unauthorized disclosure of client information in addiction counseling?

The correct choice regarding the regulation that limits unauthorized disclosure of client information in addiction counseling is 42 CFR. Specifically, 42 CFR Part 2 is a federal regulation that is designed to protect the confidentiality of substance use disorder patient records. It is particularly critical for those receiving treatment for addiction, as it provides significant restrictions on the disclosure of information without a patient's written consent.

This regulation is vital in addiction counseling because it recognizes the sensitive nature of substance use treatments and the potential stigma that clients may face. By safeguarding client data, 42 CFR encourages individuals to seek help without fear that their information will be shared with employers, law enforcement, or other parties without their permission.

Other options, while related to privacy and nondisclosure in various contexts, do not provide the specific protections tailored to addiction treatment as effectively as 42 CFR does. For instance, HIPAA (the Health Insurance Portability and Accountability Act) does offer protections for health information but is not as comprehensive regarding substance use disorder treatment records as 42 CFR. Title 21, U.S. Code section 290e relates to substance abuse research and services but does not specifically focus on client confidentiality, and the Americans with Disabilities Act (ADA) primarily addresses discrimination against individuals with disabilities rather
