Addiction, like asthma, heart disease, and other chronic illnesses, is not curable. However, it is manageable. In some cases, going to rehab more than once is part of that management process.The rate of relapse for people who get treatment for a substance use disorder is between 40 to 60 percent. When a person relapses, they can go back to rehab to assess what went wrong and how to fortify their position in recovery going forward.Relapse provides an opportunity to analyze your treatment plan and determine what can be strengthened. You will work with health care and addiction treatment professionals to make changes to your initial treatment plan. These changes will better set you up for ongoing sobriety.
