Thirty days is considered "short-term rehab," and anything longer is thought about "long-term rehabilitation." The only distinction in between rehab lengths is that treatment is more extensive in short-term rehab since more therapy is being condensed into a much shorter time period. Unlike inpatient rehabilitation, when you select an outpatient program, each step of the rehab process is typically finished at a separate center.Once that's completed, the actual treatment can start 90 days is typically a minimum, but lots of individuals continue seeing a therapist or attending group therapy for several years. The longer you invest in rehab, the more costly it will be. However, those who have severe dependencies may not get all the aid that they require in short-term rehabilitation.
