The diverse alcohol and drug abuse treatment services which are available to drug and alcohol addicted persons in Brussels can differ in several various ways. Quite a few substance abuse treatment services take place in a residential or inpatient location, where clients reside the entire time they are in rehabilitation which provides a more therapeutic rehab setting. Others provide alcohol and drug abuse rehabilitation services on an outpatient basis which provides a sense of flexibility, although outpatient programs are not always a suitable substance abuse rehab program for men and women in Brussels who are having difficulties with long term drug or alcohol addiction issues. Regardless of whether inpatient or outpatient alcohol and drug abuse rehabilitation services are selected, there are also different lengths of time that individuals will be required to stay in the drug and alcohol rehab program. For example, quite a few short-term programs provide services for 30 days or less, while long-term programs will demand at least a 3 month stay.
