Thirty days is considered "short-term rehab," and anything longer is considered "long-term rehabilitation." The only difference between rehab lengths is that treatment is more intensive in short-term rehabilitation given that more therapy is being condensed into a shorter amount of time. Unlike inpatient rehabilitation, when you go with an outpatient program, each action of the rehabilitation procedure is typically completed at a separate facility.Once that's completed, the real therapy can start 90 days is normally a minimum, however lots of individuals continue seeing a therapist or participating in group therapy for several years. The longer you invest in rehabilitation, the more expensive it will be. However, those who have serious addictions might not receive all the assistance that they require in short-term rehab.
