The different substance abuse rehabilitation services which are offered to drug addicted persons in Greenville can vary in several various ways. Some alcohol and drug abuse rehab services take place in a residential or inpatient facility, where clients reside for the duration of their rehabilitation which offers a more therapeutic rehabilitation setting. Others provide alcohol and drug abuse rehabilitation services on an outpatient basis which allows for more versatility, although outpatient facilities may not be a suitable drug and alcohol abuse rehab service for men and women in Greenville who are struggling with serious drug addiction issues. Regardless of whether inpatient or outpatient alcohol and drug abuse rehab programs are selected, there are also different lengths of time that people will be asked to remain in the drug and alcohol rehab program. For instance, quite a few short-term programs provide services for a month or less, while long-term facilities will call for at least a 90 day stay.
