The various drug and alcohol abuse rehab programs which are accessible to drug addicted persons in Alton can vary in a lot of various ways. Quite a few alcohol and drug abuse treatment services are conducted in a residential or inpatient setting, where clients reside the entire time they are in rehab which provides a more therapeutic rehab environment. Others provide substance abuse rehabilitation services on an outpatient basis which allows for more versatility, although outpatient centers are not always an appropriate substance abuse treatment program for men and women in Alton who are having difficulties with serious drug or alcohol addiction problems. Regardless of whether inpatient or outpatient alcohol and drug abuse rehab programs are selected, there are also different lengths of time that men and women will be required to continue to be in the drug and alcohol rehabilitation program. For instance, quite a few short-term programs offer services for 4 weeks or less, whereas long-term centers will require at least a 3 month stay.
