The diverse drug and alcohol abuse rehabilitation services which are offered to alcohol and drug addicted individuals in Dallas can differ in a lot of different ways. Some substance abuse rehab services are conducted in a residential or inpatient facility, where individuals reside for the duration of their rehab which offers a more conducive treatment setting. Others provide alcohol and drug abuse rehabilitation services on an outpatient basis which allows for more flexibility, although outpatient programs may not be a suitable drug and alcohol abuse rehabilitation program for individuals in Dallas who are having difficulties with serious drug addiction problems. Whether inpatient or outpatient drug and alcohol abuse treatment programs are chosen, there are also different lengths of time that people will be expected to remain in the alcohol and drug rehabilitation facility. For example, quite a few short-term programs offer programs for 30 days or less, while long-term facilities will call for at least a 12 week stay.
