The various drug and alcohol abuse rehab services which are available to alcohol and drug addicted individuals in Princeton can differ in many various ways. Quite a few alcohol and drug abuse treatment services are conducted in a residential or inpatient location, where clients remain the entire time they are in rehab which provides a more therapeutic rehabilitation setting. Others offer alcohol and drug abuse treatment programs on an outpatient basis which provides a sense of flexibility, though outpatient programs may not be an appropriate alcohol and drug abuse rehab program for individuals in Princeton who are having difficulties with long term drug or alcohol addiction problems. Regardless of whether inpatient or outpatient drug and alcohol abuse rehab programs are chosen, there are varying lengths of time that individuals will be asked to remain in the alcohol and drug treatment center. For instance, many short-term programs offer services for 4 weeks or less, whereas long-term programs will call for at least a 90 day stay.
