The various alcohol and drug abuse treatment programs which are accessible to drug and alcohol addicted persons in Brownsville can vary in several different ways. Some alcohol and drug abuse rehab services take place in a residential or inpatient setting, where clients reside the entire time they are in rehab which offers a more conducive rehabilitation environment. Others offer drug and alcohol abuse rehab programs on an outpatient basis which provides a sense of flexibility, although outpatient facilities may not be an appropriate substance abuse rehabilitation service for individuals in Brownsville who are having difficulties with serious drug addiction issues. Whether or not inpatient or outpatient substance abuse rehabilitation services are selected, there are also different lengths of time that people will be expected to continue to be in the drug and alcohol rehabilitation center. For instance, quite a few short-term programs offer services for 4 weeks or less, whereas long-term facilities will call for at least a 12 week stay.
