To ensure that drug and alcohol treatment can be available to those with co-occurring psychological problems, Partial Hospitalization drug and alcohol rehab programs in Lisle, Illinois can provide rehabilitation in special hospital and mental health hospital settings for those who need rehab. Partial Hospitalization is the term used for this kind of drug rehabilitation facility, because the individual takes part in drug and alcohol rehab in the day and will then return home at night for about seven days a week. For this reason these drug and alcohol rehab programs are also known as Day Treatment. Partial Hospitalization drug and alcohol treatment centers deal with drug addiction disorders and mental health troubles concurrently so that treatment staff can ensure that the individual avoids relapse once drug and alcohol rehab is finished.
