The diverse alcohol and drug abuse rehabilitation programs which are offered to drug addicted persons in Oakland can differ in several various ways. Quite a few drug and alcohol abuse rehab programs are offered in a residential or inpatient location, where clients reside for the duration of their rehab which provides a more conducive rehab setting. Others provide drug and alcohol abuse treatment services on an outpatient basis which provides a sense of versatility, although outpatient programs may not be a suitable substance abuse rehab program for individuals in Oakland who are struggling with serious drug addiction difficulties. Whether or not inpatient or outpatient substance abuse rehabilitation programs are selected, there are also different amounts of time that people will be asked to continue to be in the drug and alcohol rehabilitation center. For instance, many short-term programs provide services for 30 days or less, while long-term centers will require at least a 3 month stay.
