The various alcohol and drug abuse rehabilitation services which are offered to alcohol and drug addicted individuals in Lamar can vary in several various ways. Some substance abuse rehabilitation programs are offered in a residential or inpatient setting, where individuals reside the entire time they are in rehab which offers a more therapeutic treatment setting. Others offer substance abuse rehab services on an outpatient basis which provides a sense of versatility, though outpatient centers may not be a suitable substance abuse treatment service for individuals in Lamar who are having difficulties with long term drug addiction issues. Regardless of whether inpatient or outpatient alcohol and drug abuse rehabilitation services are chosen, there are also different amounts of time that individuals will be expected to continue to be in the alcohol and drug treatment center. For instance, many short-term programs provide services for 30 days or less, while long-term centers will require at least a 12 week stay.
