In an effort to make drug and alcohol rehabilitation is accessible to persons with co-occurring mental health problems, Partial Hospitalization drug and alcohol rehabilitation centers in St. Paul can offer rehabilitation in special hospital and mental health hospital settings for clients in need of rehabilitation. Partial Hospitalization is the term used for this type of drug and alcohol treatment program, due to the fact that the treatment client will undergo drug and alcohol treatment during the day and returns home at night for about seven days per week. For this reason these drug and alcohol treatment programs are also referred to as Day Treatment. Partial Hospitalization drug rehabilitation programs address drug addiction issues and psychological disorders concurrently so that treatment staff can ensure that the treatment client doesn't relapse once drug and alcohol rehabilitation is finished.
