The diverse substance abuse rehabilitation services which are available to drug addicted persons in Marissa can vary in many various ways. Some drug and alcohol abuse rehabilitation services are conducted in a residential or inpatient facility, where individuals remain for the duration of their rehabilitation which offers a more therapeutic treatment environment. Others offer alcohol and drug abuse treatment services on an outpatient basis which allows for more flexibility, though outpatient facilities may not be a suitable substance abuse rehabilitation service for people in Marissa who are struggling with long term drug addiction difficulties. Regardless of whether inpatient or outpatient alcohol and drug abuse treatment programs are chosen, there are also different lengths of time that individuals will be asked to continue to be in the alcohol and drug rehab facility. For example, many short-term programs offer services for 30 days or less, while long-term facilities will call for at least a 3 month stay.
