Though each rehab center in Massachusetts follows a different pattern of treatment, there are some similarities. Basically, there are three main stages to the rehab program in Massachusetts. These are the intervention, the detoxification and the aftercare phases.

The intervention phase begins as soon as the person has been enrolled into a rehabilitation center in Massachusetts for treatment. There is always some denial present in the persons who have been brought to treatment, even if there have been several attempts to convince the person to accept treatment beforehand. In any case, the patient needs to be encouraged to accept treatment, because without that, the person will not respond to the recovery methods. By using careful counseling and educational programs, the patients are convinced that they need treatment.

Once the convincing part is over, the patient can be led through a medical program to completely remove the addiction from their system. Here, the focus is on removing the addictive substance from their body. This phase, known as detoxification, goes on for as long as it takes to completely cleanse the person's body.

Detoxification can take a long time, depending on how intense the person's addiction has been. An aftercare program where the patient is taught certain methods and therapies that can help them to control their addictive urges follow this. The program can continue for several weeks after the detoxification program has been completed.
