The various alcohol and drug abuse rehab programs which are available to drug and alcohol addicted people in San Rafael can vary in several different ways. Some alcohol and drug abuse treatment programs take place in a residential or inpatient facility, where clients reside for the duration of their rehabilitation which provides a more therapeutic rehab environment. Others provide substance abuse treatment services on an outpatient basis which provides a sense of versatility, although outpatient programs are not always an appropriate substance abuse rehab program for individuals in San Rafael, California who are struggling with long term drug addiction difficulties. Whether or not inpatient or outpatient substance abuse treatment services are chosen, there are also different amounts of time that men and women will be asked to continue to be in the alcohol and drug rehab center. For example, quite a few short-term programs provide services for 30 days or less, whereas long-term facilities will demand at least a 12 week stay.
