The various substance abuse rehab services which are available to drug and alcohol addicted individuals in Redwood City can vary in many different ways. Quite a few alcohol and drug abuse rehab programs take place in a residential or inpatient location, where clients remain for the duration of their rehabilitation which provides a more therapeutic rehab setting. Others offer substance abuse treatment programs on an outpatient basis which provides a sense of versatility, though outpatient centers are not always a suitable substance abuse treatment service for individuals in Redwood City who are having difficulties with long term drug addiction issues. Regardless of whether inpatient or outpatient substance abuse rehab services are chosen, there are varying amounts of time that men and women will be expected to remain in the alcohol and drug treatment program. For example, many short-term programs provide services for 4 weeks or less, while long-term programs will require at least a 12 week stay.
