The diverse substance abuse rehab programs which are offered to alcohol and drug addicted individuals in Pomona can vary in a lot of different ways. Quite a few substance abuse rehabilitation programs are conducted in a residential or inpatient location, where clients reside for the duration of their rehabilitation which provides a more conducive treatment setting. Others offer alcohol and drug abuse treatment programs on an outpatient basis which allows for more versatility, although outpatient centers may not be a suitable drug and alcohol abuse treatment program for individuals in Pomona who are struggling with long term drug or alcohol addiction difficulties. Regardless of whether inpatient or outpatient drug and alcohol abuse rehab programs are chosen, there are also different amounts of time that people will be expected to remain in the alcohol and drug rehab center. For instance, some short-term programs offer services for a month or less, whereas long-term programs will demand at least a 3 month stay.
