The diverse drug and alcohol abuse rehabilitation programs which are accessible to drug addicted people in Arcata, California can vary in many different ways. Some drug and alcohol abuse treatment programs are offered in a residential or inpatient facility, where individuals reside the entire time they are in rehab which supplies a more therapeutic rehab setting. Others offer substance abuse rehab services on an outpatient basis which allows for more flexibility, though outpatient facilities are not always an appropriate drug and alcohol abuse treatment program for individuals in Arcata who are having difficulties with serious drug addiction issues. Regardless of whether inpatient or outpatient substance abuse rehab services are chosen, there are varying lengths of time that people will be expected to continue to be in the drug and alcohol rehabilitation program. For instance, many short-term programs provide services for a month or less, while long-term programs will require at least a 90 day stay.
