The different drug and alcohol abuse rehab services which are offered to drug and alcohol addicted individuals in Lima can differ in many various ways. Quite a few alcohol and drug abuse rehab services are offered in a residential or inpatient setting, where clients remain the entire time they are in rehab which provides a more conducive rehab environment. Others provide substance abuse rehab services on an outpatient basis which allows for more flexibility, though outpatient centers may not be an appropriate alcohol and drug abuse treatment program for individuals in Lima who are struggling with long term drug or alcohol addiction issues. Regardless of whether inpatient or outpatient alcohol and drug abuse treatment services are chosen, there are also different lengths of time that men and women will be asked to remain in the drug and alcohol rehab facility. For instance, some short-term programs provide programs for a month or less, while long-term facilities will call for at least a 3 month stay.
