The different drug and alcohol abuse rehabilitation services which are available to alcohol and drug addicted individuals in Stanford, California can differ in a lot of different ways. Quite a few substance abuse rehab services are offered in a residential or inpatient setting, where clients remain the entire time they are in treatment which offers a more conducive treatment environment. Others provide alcohol and drug abuse rehab programs on an outpatient basis which allows for more flexibility, although outpatient programs are not always a suitable substance abuse rehab program for individuals in Stanford who are struggling with serious addiction difficulties. Whether or not inpatient or outpatient drug and alcohol abuse rehabilitation programs are selected, there are also different amounts of time that individuals will be expected to continue to be in the alcohol and drug rehab center. For instance, many short-term programs provide services for 4 weeks or less, whereas long-term centers will demand at least a 90 day stay.
