The different drug and alcohol abuse treatment programs which are available to drug and alcohol addicted individuals in St. Louis can differ in several different ways. Some alcohol and drug abuse treatment programs are offered in a residential or inpatient facility, where individuals reside for the duration of their rehab which offers a more therapeutic rehab environment. Others provide drug and alcohol abuse rehabilitation programs on an outpatient basis which allows for more versatility, although outpatient facilities may not be a suitable drug and alcohol abuse rehabilitation service for individuals in St. Louis who are having difficulties with long term drug or alcohol addiction issues. Whether inpatient or outpatient drug and alcohol abuse treatment services are chosen, there are varying amounts of time that individuals will be required to continue to be in the drug treatment facility. For instance, many short-term programs offer programs for 4 weeks or less, while long-term centers will require at least a 12 week stay.
