The different substance abuse rehabilitation programs which are accessible to drug and alcohol addicted individuals in Annandale can differ in a lot of different ways. Quite a few substance abuse treatment services are conducted in a residential or inpatient setting, where individuals remain for the duration of their rehab which supplies a more therapeutic treatment environment. Others offer substance abuse rehab services on an outpatient basis which allows for more flexibility, though outpatient facilities are not always an appropriate alcohol and drug abuse treatment service for individuals in Annandale who are struggling with long term drug addiction difficulties. Whether or not inpatient or outpatient drug and alcohol abuse treatment services are selected, there are varying amounts of time that people will be asked to stay in the drug treatment facility. For example, quite a few short-term programs provide programs for 30 days or less, whereas long-term facilities will call for at least a 12 week stay.
