The various alcohol and drug abuse treatment programs which are offered to drug addicted individuals in Charleston can vary in many various ways. Some substance abuse treatment services take place in a residential or inpatient location, where clientele remain for the duration of their rehab which provides a more therapeutic rehabilitation environment. Others provide substance abuse treatment services on an outpatient basis which provides a sense of flexibility, although outpatient centers may not be an appropriate alcohol and drug abuse treatment program for men and women in Charleston who are struggling with serious addiction difficulties. Whether or not inpatient or outpatient substance abuse treatment programs are selected, there are also different lengths of time that people will be asked to stay in the drug and alcohol treatment program. For example, some short-term programs offer programs for 30 days or less, whereas long-term centers will require at least a 90 day stay.
