Partial Hospitalization, also known as "PHP" or Day Treatment, is a form of recovery program which works to treat substance abuse issues and mental health issues which may be co-occurring. In a PHP program, the person in treatment participates in various recovery activities and techniques during the day and then returns home in the evening. This takes place anywhere from five to seven days a week, depending on the seriousness of the problem. Partial Hospitalization can be helpful for addicted individuals who may not be able to afford long-term inpatient care, or who are unable to be away from their families for prolonged periods of time. While in Day Treatment, individuals take part in standard counseling and therapy for addiction issues while also addressing mental health problems which could prevent them from making progress and obtaining gains throughout the treatment process.

Criminal justice clients frequently need substance abuse rehabilitation due to problems with drug and alcohol abuse. Due to the nature of the criminal justice system, there are specific steps and guidelines that must be performed in order to be admitted into a criminal justice drug rehabilitation program or recovery program. The first step is to determine the criminal justice clients eligibility. This step is accomplished by a panel of officials who determine how much and what type of treatment is necessary. Sometimes, the criminal justice clients obtain their substance abuse treatment while they are incarcerated. For optimum results, they are encouraged, if not strictly directed, to continue their recovery once they leave jail and enroll in sober living or a therapeutic community.

Many substance abuse rehab programs in the United States provide payment assistance to people struggling with drug or alcohol addiction and want to get help. The person in need of treatment can select a rehab facility which is a good fit, meaning the treatment curriculum and design of the program will offer them the best results. The addicted individual can then consult with one of the treatment professionals at the drug or alcohol rehab facility to talk about what kind of payment assistance options are available or that they qualify for. The financial department in most drug treatment centers are more than willing to work with potential clients to get them started by offering payment assistance, and if this is unavailable, treatment professionals will usually work with the individual to locate an equivalent or comparable rehab program which is more affordable or that can offer workable financing options so that they can acquire the rehabilitation they so desperately need.
