The different substance abuse treatment services which are offered to alcohol and drug addicted individuals in Mercedes can vary in several different ways. Quite a few drug and alcohol abuse treatment programs take place in a residential or inpatient setting, where individuals remain the entire time they are in treatment which supplies a more conducive rehab setting. Others provide drug and alcohol abuse rehabilitation services on an outpatient basis which provides a sense of versatility, though outpatient facilities may not be an appropriate drug and alcohol abuse rehabilitation program for people in Mercedes who are having difficulties with long term drug addiction difficulties. Whether or not inpatient or outpatient substance abuse rehabilitation services are selected, there are also different amounts of time that people will be required to remain in the drug rehab program. For example, many short-term programs provide programs for 30 days or less, whereas long-term programs will require at least a 90 day stay.
