One month is thought about "short-term rehabilitation," and anything longer is thought about "long-term rehabilitation." The only distinction between rehab lengths is that treatment is more extensive in short-term rehabilitation since more treatment is being condensed into a shorter amount of time. Unlike inpatient rehabilitation, when you go with an outpatient program, each action of the rehabilitation process is normally finished at a separate center.When that's completed, the real treatment can begin 90 days is usually a minimum, but many people continue seeing a counselor or going to group therapy for numerous years. The longer you invest in rehab, the more costly it will be. However, those who have severe dependencies might not get all the assistance that they need in short-term rehabilitation.
