The diverse drug and alcohol abuse treatment programs which are offered to drug and alcohol addicted people in Champaign can differ in many different ways. Some drug and alcohol abuse rehab services are offered in a residential or inpatient location, where clients remain the entire time they are in rehab which provides a more conducive rehabilitation environment. Others provide substance abuse rehabilitation services on an outpatient basis which allows for more flexibility, though outpatient facilities are not always a suitable alcohol and drug abuse rehab service for men and women in Champaign who are struggling with long term drug or alcohol addiction problems. Whether inpatient or outpatient drug and alcohol abuse rehabilitation programs are selected, there are varying amounts of time that people will be required to continue to be in the drug and alcohol treatment center. For example, quite a few short-term programs offer services for 30 days or less, while long-term centers will call for at least a 3 month stay.
