The various alcohol and drug abuse rehabilitation programs which are offered to drug and alcohol addicted people in Lewiston can differ in many various ways. Some substance abuse rehab services are offered in a residential or inpatient location, where clientele reside the entire time they are in rehab which provides a more conducive rehab environment. Others provide drug and alcohol abuse rehabilitation services on an outpatient basis which provides a sense of versatility, though outpatient centers are not always an appropriate drug and alcohol abuse rehab program for people in Lewiston who are struggling with serious addiction issues. Whether or not inpatient or outpatient substance abuse rehab services are selected, there are also different amounts of time that men and women will be asked to continue to be in the drug and alcohol treatment facility. For example, quite a few short-term programs offer services for 4 weeks or less, while long-term facilities will call for at least a 3 month stay.
