The different drug and alcohol abuse treatment programs which are accessible to drug and alcohol addicted individuals in Harlan can differ in several various ways. Quite a few substance abuse rehab programs take place in a residential or inpatient setting, where clients reside for the duration of their rehab which provides a more conducive treatment environment. Others offer alcohol and drug abuse rehab services on an outpatient basis which allows for more versatility, though outpatient centers may not be an appropriate drug and alcohol abuse rehab service for people in Harlan who are struggling with long term addiction issues. Whether inpatient or outpatient alcohol and drug abuse treatment services are chosen, there are varying lengths of time that people will be expected to continue to be in the alcohol and drug treatment center. For instance, many short-term programs offer programs for a month or less, while long-term programs will demand at least a 12 week stay.
