The various alcohol and drug abuse rehab programs which are offered to drug addicted individuals in Parsons can vary in several various ways. Some substance abuse treatment services are conducted in a residential or inpatient setting, where clients reside the entire time they are in rehab which offers a more conducive rehabilitation environment. Others offer substance abuse treatment services on an outpatient basis which allows for more flexibility, although outpatient programs may not be a suitable drug and alcohol abuse rehab service for people in Parsons who are having difficulties with serious drug or alcohol addiction difficulties. Whether inpatient or outpatient drug and alcohol abuse rehabilitation programs are selected, there are varying lengths of time that people will be asked to continue to be in the drug rehabilitation program. For example, many short-term programs provide programs for 30 days or less, while long-term facilities will call for at least a 90 day stay.
