The various alcohol and drug abuse rehab services which are available to alcohol and drug addicted people in Lafayette, California can vary in a lot of different ways. Some alcohol and drug abuse treatment programs are offered in a residential or inpatient location, where clients reside for the duration of their rehabilitation which provides a more therapeutic rehab setting. Others provide substance abuse treatment programs on an outpatient basis which provides a sense of flexibility, though outpatient centers are not always a suitable substance abuse rehab service for individuals in Lafayette who are having difficulties with serious drug addiction issues. Whether or not inpatient or outpatient drug and alcohol abuse treatment services are chosen, there are also different lengths of time that individuals will be required to continue to be in the drug rehab center. For instance, some short-term programs offer programs for 4 weeks or less, whereas long-term facilities will require at least a 3 month stay.
