Addiction treatment is private and there are regulations that ensure the privacy of people who attend all treatment facilities. The foundation of a rehab center is built on the privacy and confidentiality of the clients and anyone who contacts them. Due to the delicate nature of the services, rehab centers will never share your information with anyone unless mandated by law to do so, or with your permission. All staff members of most rehab centers sign very strict Non-Disclosure and confidentiality agreements.
