Federal Supervised Release doesn't have either. Drug Court would be different than re-entry. If you are asking about a federal inmate, neither would apply.
If you are asking about a state case, you want to go to the State of Maryland for information on the state programs.
If your loved one went through RDAP, there is unique drug treatment they will have to go through, especially for the first 6 months. I think it varies from region to region, but it could include extra AA/NA groups, or individual or group therapy. It all depends on what his Supervisor decides to implement.
