The diverse substance abuse treatment services which are accessible to drug addicted people in San Marcos, California can differ in many different ways. Quite a few drug and alcohol abuse treatment programs take place in a residential or inpatient setting, where clients remain the entire time they are in rehabilitation which supplies a more therapeutic rehab setting. Others offer alcohol and drug abuse rehabilitation services on an outpatient basis which provides a sense of flexibility, though outpatient programs are not always an appropriate substance abuse rehab service for people in San Marcos who are struggling with serious addiction difficulties. Regardless of whether inpatient or outpatient substance abuse rehab services are selected, there are varying lengths of time that men and women will be asked to remain in the drug and alcohol treatment program. For instance, quite a few short-term programs provide services for a month or less, while long-term programs will call for at least a 90 day stay.
