Does Drug Treatment Programs Include Activities or Lectures Regarding Family Issues?

My brother Jeff checked into a drug rehab a week ago and I miss him. He says that he’s doing just fine and that he’s enjoying the activities and the lectures included in the program. I think he’s in for a fast recovery. Before entering rehab, he had a rift with our dad. They had a fight about his addiction with marijuana. There were shouting and blaming all over the place that the only thing that my mom managed to do is cry. I was wondering if the rehab provides lectures or discussions about rebuilding relationships with family members. I’m wishing for a reconciliation between Jeff and dad.
