The various substance abuse rehab services which are offered to drug and alcohol addicted people in Marshall, California can vary in several various ways. Quite a few alcohol and drug abuse rehab services are offered in a residential or inpatient location, where individuals remain the entire time they are in treatment which supplies a more therapeutic rehab setting. Others provide alcohol and drug abuse rehabilitation programs on an outpatient basis which allows for more flexibility, although outpatient programs are not always an appropriate drug and alcohol abuse rehabilitation program for people in Marshall who are having difficulties with long term drug or alcohol addiction problems. Regardless of whether inpatient or outpatient substance abuse rehabilitation services are selected, there are varying lengths of time that people will be required to remain in the drug and alcohol treatment center. For example, many short-term programs offer programs for 4 weeks or less, while long-term programs will require at least a 90 day stay.
