I absolutely loved this treatment facility. From beginning to end I was treated with respect and compassion from all the staff. I learned a lot about myself and the disease of addiction and was also was taught coping skills and pre lapse signs. Definitely recommend anyone seeking treatment for themselves or a family member to check out Cornerstone Detox Residential, Phase 1 & 2 , and IOP.

BEST DECISION OF MY LIFE! I called Cornerstone on my own accord when I knew I needed help and could not detox or handle my alcoholism on my own anymore. Going to a rehab facility is a scary thought, but once I arrived all fear and anxiety disappeared, I knew I was in a safe place. The staff makes every effort to make sure that you are comfortable. Group sessions with the counselors have taught me lessons that will be with me for life. I have learned more about myself in the short time I was at Cornerstone, than I have in my entire 32 years at of life

What to expect during Rehab

The specifics of what you can expect during rehab will depend on the type of treatment program you are in and your individual needs and goals. In general, however, you can expect the following during rehab:

Drug Rehab Costa Mesa

Drug Addiction Assessment #1

The first step to recovery is understanding. We offer free and private drug addiction assessments to anyone who is concerned that they may require alcohol or drug rehab. At a pre-admission assessment, you will speak with one of our addiction specialists as they work to discover the scope and depth of your substance abuse, the impacts it has had on your life, and your current living situation. They can also point out any mental health issues that may be present in addition to the addiction. A dual diagnosis is a medical approach to drug abuse treatment that recognizes the connection between emotional well-being and mental sickness and substance use disorders.

Drug Detox Costa Mesa #2

The next stage is to begin a detox, which is the process of the body eliminating toxins (in this case, the substance of abuse). Detoxification, or detox, refers to both the natural process that takes place when your body rids itself of poisons (in this case, the drug) and also the medical procedure that aids it. Intense withdrawal symptoms affect individuals who have been binging or using a drug for an extended period. Depending on your demands, which are evaluated on a regular basis, we provide medication-assisted treatment and support at our drug and alcohol detox facilities. We put the health and well-being of our clients above all else.

Inpatient or Outpatient Treatment #3

The vast majority of our clients choose to continue with us for our twenty-eight-day inpatient residential treatment program at Cornerstone. We encourage our clients to devote their whole attention and effort during the duration of the program by visiting one of our pleasant, modern campuses. Inpatient care provides patients with 24-hour medical supervision on a substance-free campus, where they may use the beautiful state-of-the-art treatment centers filled with dynamic activities and peaceful downtime to meditate and reflect. You’ll also get a full program of physical and occupational therapy, fresh, nutritious meals prepared on-site, and a helpful community of other Cornerstone rehabilitation center patients to help you through your stay.

Post-Treatment Addiction Care #4

After completing one of our substance abuse treatments, you will continue to work on your recovery. Addiction treatment is often a time to retreat and learn new skills, fully engage with therapy, and grow your coping mechanism toolkit so that you may live your life without giving in to drug addiction outside of rehab. We do not have to return to real life without a support system. However, we must overcome the challenges of returning to reality: we face daily pressures and difficulties. Many people’s jobs, finances, and even social relationships are lost due to addiction or other problems. We want you to have a smooth and stress-free transition from one facility to the next. After addiction treatment, you will get assistance in coming up with an extended care plan for yourself following rehabilitation.

The average length of rehab is typically around 30 to 90 days. However, it is worth noting that the ideal length of rehab will vary from person to person, and it is important to choose a program that is tailored to your specific needs and goals.

The minimum length of rehab is usually a few days, although some programs may be shorter. These shorter programs are often referred to as “detox” programs, and they are designed to help the individual safely withdraw from the substance they are addicted to.


The maximum length of rehab is usually several months, although some programs may last longer. These longer programs are often referred to as “residential” programs, and they typically involve a more intensive level of treatment.

When you complete a rehab program, you will typically have a number of options for continuing your recovery journey. This may include developing an aftercare plan, returning to daily life, seeking ongoing support, and coping with challenges. The goal of rehab is to provide you with the tools and support you need to build a strong foundation for lasting recovery.

At our rehab center, the cost of drug and alcohol rehab can vary depending on the type of treatment being provided and the length of stay. Many insurance plans cover some or all of the cost of rehab, and we can help you verify your insurance to determine your coverage. If you have questions about the cost of rehab or how to pay for it, please don’t hesitate to contact us for more information.
