The different substance abuse treatment programs which are accessible to drug addicted individuals in Grinnell can vary in several various ways. Some drug and alcohol abuse rehabilitation services are offered in a residential or inpatient setting, where individuals remain the entire time they are in rehabilitation which provides a more conducive rehabilitation environment. Others provide substance abuse rehabilitation programs on an outpatient basis which provides a sense of flexibility, although outpatient facilities may not be an appropriate substance abuse rehabilitation program for men and women in Grinnell who are having difficulties with long term drug or alcohol addiction problems. Whether or not inpatient or outpatient substance abuse rehab services are chosen, there are varying amounts of time that people will be asked to stay in the alcohol and drug treatment facility. For example, some short-term programs offer programs for 4 weeks or less, while long-term facilities will call for at least a 90 day stay.
