The various alcohol and drug abuse rehab services which are accessible to drug and alcohol addicted individuals in Collinsville can vary in several different ways. Some substance abuse treatment programs take place in a residential or inpatient facility, where individuals remain the entire time they are in treatment which supplies a more conducive rehabilitation environment. Others provide alcohol and drug abuse treatment programs on an outpatient basis which provides a sense of versatility, though outpatient facilities are not always a suitable substance abuse rehabilitation service for people in Collinsville who are struggling with serious drug or alcohol addiction problems. Whether or not inpatient or outpatient drug and alcohol abuse treatment services are selected, there are varying lengths of time that individuals will be expected to continue to be in the drug and alcohol rehabilitation facility. For instance, some short-term programs offer programs for 4 weeks or less, while long-term centers will call for at least a 12 week stay.
