The various drug and alcohol abuse rehab programs which are available to alcohol and drug addicted persons in La Salle can vary in many various ways. Some substance abuse treatment services are offered in a residential or inpatient facility, where individuals reside for the duration of their rehab which provides a more therapeutic treatment environment. Others provide alcohol and drug abuse treatment programs on an outpatient basis which provides a sense of versatility, though outpatient centers are not always an appropriate alcohol and drug abuse rehabilitation service for people in La Salle who are struggling with long term drug or alcohol addiction issues. Whether or not inpatient or outpatient drug and alcohol abuse rehabilitation services are chosen, there are also different lengths of time that people will be expected to continue to be in the drug rehabilitation program. For instance, some short-term programs provide programs for a month or less, whereas long-term facilities will require at least a 90 day stay.
