The different alcohol and drug abuse rehab services which are available to alcohol and drug addicted individuals in Allen can differ in several different ways. Some substance abuse rehabilitation programs are conducted in a residential or inpatient location, where individuals remain for the duration of their treatment which offers a more therapeutic rehab setting. Others offer alcohol and drug abuse rehab programs on an outpatient basis which provides a sense of versatility, although outpatient programs may not be an appropriate alcohol and drug abuse rehabilitation program for men and women in Allen who are having difficulties with long term drug or alcohol addiction problems. Whether or not inpatient or outpatient substance abuse rehabilitation programs are chosen, there are varying amounts of time that men and women will be asked to continue to be in the drug and alcohol treatment program. For instance, many short-term programs offer services for 4 weeks or less, whereas long-term programs will call for at least a 3 month stay.
