The different substance abuse rehab programs which are offered to alcohol and drug addicted individuals in Oakland can vary in many different ways. Some substance abuse rehabilitation programs take place in a residential or inpatient facility, where individuals reside the entire time they are in rehab which offers a more therapeutic treatment environment. Others provide drug and alcohol abuse treatment services on an outpatient basis which provides a sense of versatility, though outpatient facilities may not be a suitable alcohol and drug abuse treatment service for people in Oakland who are having difficulties with long term drug addiction problems. Whether or not inpatient or outpatient substance abuse treatment programs are chosen, there are also different amounts of time that individuals will be asked to continue to be in the alcohol and drug rehab program. For instance, many short-term programs offer services for a month or less, while long-term facilities will demand at least a 3 month stay.
