The diverse drug and alcohol abuse treatment services which are offered to alcohol and drug addicted individuals in Colchester can vary in many different ways. Some drug and alcohol abuse rehab programs take place in a residential or inpatient setting, where clients reside the entire time they are in rehabilitation which offers a more conducive rehabilitation environment. Others offer alcohol and drug abuse treatment services on an outpatient basis which provides a sense of flexibility, though outpatient programs may not be an appropriate alcohol and drug abuse rehab program for people in Colchester who are struggling with long term drug or alcohol addiction problems. Regardless of whether inpatient or outpatient drug and alcohol abuse rehab programs are chosen, there are also different lengths of time that men and women will be asked to stay in the alcohol and drug treatment center. For instance, many short-term programs offer services for 4 weeks or less, while long-term centers will call for at least a 90 day stay.
