The different alcohol and drug abuse rehabilitation programs which are offered to drug and alcohol addicted individuals in Clarence can differ in a lot of different ways. Quite a few drug and alcohol abuse treatment services are offered in a residential or inpatient location, where clients remain for the duration of their rehabilitation which provides a more therapeutic treatment environment. Others offer substance abuse treatment programs on an outpatient basis which provides a sense of versatility, although outpatient centers are not always an appropriate substance abuse rehabilitation program for men and women in Clarence who are struggling with long term drug or alcohol addiction problems. Whether or not inpatient or outpatient alcohol and drug abuse treatment services are chosen, there are varying amounts of time that people will be asked to remain in the drug and alcohol rehab facility. For example, quite a few short-term programs provide programs for 30 days or less, while long-term facilities will call for at least a 3 month stay.
