The various substance abuse treatment services which are offered to alcohol and drug addicted individuals in Vanport can vary in many various ways. Some substance abuse rehab programs are conducted in a residential or inpatient setting, where individuals reside for the duration of their treatment which offers a more therapeutic treatment environment. Others offer alcohol and drug abuse rehab programs on an outpatient basis which provides a sense of versatility, although outpatient centers may not be an appropriate substance abuse rehab service for individuals in Vanport who are having difficulties with serious drug addiction problems. Whether or not inpatient or outpatient drug and alcohol abuse treatment services are chosen, there are varying lengths of time that men and women will be required to remain in the alcohol and drug rehabilitation center. For instance, some short-term programs provide services for 4 weeks or less, while long-term facilities will require at least a 3 month stay.
