The various drug and alcohol abuse rehab programs which are available to alcohol and drug addicted individuals in Oakley, California can differ in many various ways. Quite a few substance abuse treatment services are offered in a residential or inpatient setting, where clients reside for the duration of their rehabilitation which supplies a more conducive rehab environment. Others provide substance abuse rehab programs on an outpatient basis which allows for more versatility, though outpatient centers may not be an appropriate alcohol and drug abuse rehabilitation service for people in Oakley who are struggling with long term drug addiction problems. Whether inpatient or outpatient substance abuse rehabilitation services are selected, there are also different amounts of time that people will be expected to remain in the alcohol and drug rehabilitation center. For example, quite a few short-term programs offer services for 30 days or less, whereas long-term centers will call for at least a 90 day stay.
