The various drug and alcohol abuse treatment programs which are accessible to drug addicted people in Clarksville can differ in a lot of different ways. Quite a few substance abuse rehab programs are offered in a residential or inpatient setting, where individuals reside for the duration of their treatment which offers a more conducive rehabilitation setting. Others offer alcohol and drug abuse rehabilitation services on an outpatient basis which allows for more versatility, though outpatient facilities are not always a suitable alcohol and drug abuse rehab service for men and women in Clarksville who are struggling with long term drug or alcohol addiction issues. Regardless of whether inpatient or outpatient alcohol and drug abuse rehab services are selected, there are varying lengths of time that men and women will be required to continue to be in the alcohol and drug rehabilitation center. For example, some short-term programs provide programs for a month or less, while long-term centers will call for at least a 90 day stay.
