Frequently Asked Questions About Drug Rehab in
Santa Ana, CA
There's no universal rule about how long a stay in drug rehab may last for an individual. Medical professionals and addiction professionals develop treatment plans for every individual who enters treatment, designed to address their particular needs.
Cornerstone has been a leader in drug rehab and dual diagnosis treatment since 1984, and our comprehensive treatment programs are designed to serve the needs of the whole person. We believe healing is a lifelong effort, and we’re here to provide support at every stage. Cornerstone is one of the most established treatment centers in the United States, and we’re here to help.
At Cornerstone, we strongly believe in family involvement during a person’s recovery from addiction. We encourage and facilitate connection with family and community during the healing process.
If the people in your life have voiced concern about your substance use, you've had encounters with the law based on substance use disorder, or you're unable to meet your obligations due to using substances, it may be time to consider entering drug rehab.
No. Having a mental health condition only means that it's important to seek out a drug rehab that provides dual-diagnosis treatment for your condition. For example, if you want to enter drug rehab for alcohol use disorder but also have a diagnosis of bipolar disorder, dual-diagnosis treatment can provide bipolar disorder treatment that supports not using alcohol for self-medication.
Cornerstone provides specialized programs that include a residential program, PHPs, IOPs, an extended care program, and much more. If the program you need for long-term recovery isn't immediately available, we'll refer you to a location that can better serve your needs.
Addiction specialists and medical professionals can help you determine what level of addiction treatment will best suit your needs. Needing a more intensive level of treatment doesn't mean anything about you — the best level of treatment is whatever will lead you to a place of sustained recovery.
Most insurance providers provide some level of coverage under the coverage of the Affordable Care Act and other laws. Coverage may vary by company or individual policy, so it's important to verify coverage before entering treatment.
