The diverse substance abuse treatment services which are available to drug and alcohol addicted individuals in Tomales can differ in several different ways. Some substance abuse rehab services are conducted in a residential or inpatient facility, where clients remain the entire time they are in rehabilitation which offers a more therapeutic rehabilitation setting. Others provide drug and alcohol abuse treatment programs on an outpatient basis which allows for more flexibility, although outpatient facilities are not always an appropriate substance abuse treatment service for individuals in Tomales who are having difficulties with serious drug or alcohol addiction problems. Whether or not inpatient or outpatient drug and alcohol abuse rehab services are chosen, there are varying lengths of time that individuals will be required to remain in the alcohol and drug treatment facility. For example, some short-term programs offer services for 30 days or less, while long-term facilities will demand at least a 3 month stay.
