Recovering from substance abuse typically requires two phases. Initially, a substance abuser will deal with the physiological aspects of the addiction in the rehabilitation phase. Group therapy is then used to deal with the psychological aspects, where it’s more about the “why”.
Group therapy offers social support to a group of people who are experiencing similar issues at the same time.
There are advantages of sharing your experience and listening to others who feel similarly to you and can better understand and relate to your story. Group therapy sessions are led by licensed therapists – sometimes one therapist, but often an entire team with various skill sets.
