The different substance abuse rehabilitation programs which are offered to drug and alcohol addicted individuals in Penngrove can differ in several various ways. Quite a few substance abuse treatment programs are offered in a residential or inpatient setting, where individuals reside for the duration of their rehab which provides a more conducive rehabilitation setting. Others offer alcohol and drug abuse rehabilitation services on an outpatient basis which provides a sense of versatility, though outpatient facilities are not always an appropriate substance abuse rehabilitation program for men and women in Penngrove who are having difficulties with serious drug or alcohol addiction issues. Whether inpatient or outpatient substance abuse rehabilitation programs are chosen, there are varying amounts of time that people will be required to continue to be in the drug and alcohol treatment program. For example, many short-term programs provide services for 30 days or less, while long-term programs will demand at least a 12 week stay.
