One month is thought about "short-term rehab," and anything longer is thought about "long-lasting rehabilitation." The only difference in between rehab lengths is that treatment is more extensive in short-term rehab considering that more therapy is being condensed into a shorter time period. Unlike inpatient rehabilitation, when you go with an outpatient program, each step of the rehab process is normally completed at a different center.As soon as that's completed, the real treatment can start 90 days is typically a minimum, but many people continue seeing a counselor or participating in group therapy for numerous years. The longer you invest in rehab, the more expensive it will be. Nevertheless, those who have serious addictions may not get all the help that they need in short-term rehab.
