The diverse alcohol and drug abuse rehab services which are accessible to alcohol and drug addicted individuals in Princeton can vary in many various ways. Quite a few alcohol and drug abuse rehabilitation programs are offered in a residential or inpatient setting, where individuals remain the entire time they are in rehab which provides a more conducive rehab environment. Others offer substance abuse rehabilitation programs on an outpatient basis which provides a sense of versatility, though outpatient programs are not always an appropriate substance abuse treatment service for men and women in Princeton who are struggling with serious addiction issues. Whether or not inpatient or outpatient substance abuse rehab programs are chosen, there are also different amounts of time that individuals will be asked to remain in the alcohol and drug rehabilitation center. For instance, many short-term programs provide services for 4 weeks or less, while long-term centers will call for at least a 3 month stay.
