National Association on Drug Abuse Programs (NADAP) Data Breach

Attorneys working with ClassAction.org are looking into whether a class action lawsuit can be filed in light of the NADAP data breach.

As part of their investigation, they need to hear from individuals who had their information exposed in the incident , including those who received notice of the NADAP data breach or otherwise believe they are affected.

The National Association on Drug Abuse Programs (NADAP) has reported a data breach potentially affecting personal and health information of clients, employees, and others connected to the organization.

A notice posted to NADAP’s website states that suspicious activity was first identified around January 10, 2026. According to a press release from NYC Health + Hospitals , further investigation revealed that unauthorized access occurred on or around November 26, 2025. By January 27, 2026, it was determined that affected data might include names, Social Security numbers, birth dates, health insurance information, and other health and financial information. NADAP has since enhanced security measures and notified relevant authorities.

NYC Health + Hospitals revealed that 5,086 of its patients were affected in the NADAP data breach, with compromised data including names, birth dates, addresses, Medicaid numbers, Social Security numbers, and clinical information. NADAP is a key partner in NYC Health + Hospitals' Lead Health program.

Across seven locations in NYC and Long Island, NADAP supports over 35,000 underserved New Yorkers annually with access to healthcare, employment, and community support.

If your information was exposed in the NADAP data breach, attorneys want to hear from you. You may be able to start a class action lawsuit to recover compensation for loss of privacy, time spent dealing with the breach, out-of-pocket costs, and more.

A successful case could also force NADAP to ensure they take proper steps to protect the information they were entrusted with.
