The diverse drug and alcohol abuse treatment services which are available to drug addicted individuals in San Diego can vary in several different ways. Quite a few substance abuse treatment services are offered in a residential or inpatient setting, where individuals remain the entire time they are in rehab which provides a more conducive rehab environment. Others provide substance abuse rehab services on an outpatient basis which provides a sense of versatility, though outpatient programs are not always a suitable alcohol and drug abuse treatment program for men and women in San Diego, California who are having difficulties with long term addiction difficulties. Whether inpatient or outpatient alcohol and drug abuse rehab programs are selected, there are also different amounts of time that individuals will be expected to remain in the drug and alcohol treatment program. For example, many short-term programs provide services for 4 weeks or less, whereas long-term facilities will demand at least a 90 day stay.
