The various substance abuse rehab programs which are accessible to alcohol and drug addicted persons in Rowlett can vary in many different ways. Some substance abuse treatment services take place in a residential or inpatient facility, where individuals remain the entire time they are in rehabilitation which provides a more therapeutic treatment environment. Others provide substance abuse treatment programs on an outpatient basis which provides a sense of versatility, although outpatient facilities are not always an appropriate alcohol and drug abuse treatment program for people in Rowlett who are struggling with long term drug or alcohol 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 expected to stay in the drug and alcohol rehabilitation facility. For example, some short-term programs offer programs for 4 weeks or less, whereas long-term programs will demand at least a 3 month stay.
