The various drug and alcohol abuse rehab programs which are available to drug and alcohol addicted people in Davis can differ in many various ways. Some drug and alcohol abuse rehabilitation programs are offered in a residential or inpatient location, where clients reside for the duration of their rehab which provides a more therapeutic rehabilitation environment. Others provide alcohol and drug abuse rehab services on an outpatient basis which allows for more versatility, although outpatient facilities may not be a suitable substance abuse rehab service for individuals in Davis who are having difficulties with serious addiction issues. Whether inpatient or outpatient substance abuse treatment programs are selected, there are also different amounts of time that people will be asked to continue to be in the drug rehabilitation program. For example, many short-term programs provide services for 30 days or less, while long-term centers will call for at least a 12 week stay.
