The various alcohol and drug abuse treatment services which are available to drug addicted people in Calexico can vary in many different ways. Quite a few alcohol and drug abuse rehabilitation services take place in a residential or inpatient setting, where clients reside the entire time they are in rehab which offers a more therapeutic treatment environment. Others offer drug and alcohol abuse rehabilitation services on an outpatient basis which provides a sense of flexibility, though outpatient programs are not always an appropriate substance abuse rehab program for individuals in Calexico who are struggling with serious addiction issues. Whether inpatient or outpatient substance abuse treatment services are selected, there are varying amounts of time that men and women will be expected to remain in the drug rehabilitation program. For example, many short-term programs provide programs for 30 days or less, whereas long-term facilities will require at least a 3 month stay.
