The diverse drug and alcohol abuse treatment programs which are offered to drug and alcohol addicted persons in San Antonio can vary in many various ways. Some alcohol and drug abuse treatment programs are conducted in a residential or inpatient facility, where clients remain for the duration of their treatment which offers a more therapeutic rehabilitation environment. Others offer substance abuse treatment programs on an outpatient basis which provides a sense of versatility, although outpatient programs may not be an appropriate drug and alcohol abuse rehab service for people in San Antonio who are struggling with serious addiction issues. Regardless of whether inpatient or outpatient alcohol and drug abuse rehabilitation services are selected, there are varying amounts of time that people will be required to stay in the alcohol and drug treatment facility. For instance, many short-term programs offer programs for 30 days or less, whereas long-term facilities will call for at least a 3 month stay.
