The diverse alcohol and drug abuse rehabilitation programs which are available to alcohol and drug addicted persons in Dennis can vary in many various ways. Some alcohol and drug abuse rehabilitation services are offered in a residential or inpatient facility, where individuals remain for the duration of their rehab which provides a more therapeutic rehabilitation environment. Others provide drug and alcohol abuse rehabilitation programs on an outpatient basis which allows for more flexibility, though outpatient programs may not be an appropriate drug and alcohol abuse treatment program for men and women in Dennis who are struggling with long term drug or alcohol addiction issues. Regardless of whether inpatient or outpatient drug and alcohol abuse rehabilitation services are chosen, there are varying amounts of time that men and women will be expected to continue to be in the drug and alcohol rehabilitation program. For instance, some short-term programs provide programs for 30 days or less, whereas long-term programs will demand at least a 3 month stay.
