The different substance abuse rehab services which are offered to drug and alcohol addicted persons in Brentwood, California can differ in several various ways. Quite a few substance abuse rehabilitation services are offered in a residential or inpatient location, where individuals remain the entire time they are in treatment which supplies a more therapeutic treatment setting. Others offer alcohol and drug abuse treatment programs on an outpatient basis which allows for more versatility, although outpatient facilities are not always a suitable alcohol and drug abuse treatment program for men and women in Brentwood who are having difficulties with serious drug addiction difficulties. Regardless of whether inpatient or outpatient alcohol and drug abuse rehab services are chosen, there are varying lengths of time that men and women will be expected to stay in the alcohol and drug rehabilitation facility.
