Hippa laws afford no protections for people that are engaged in illegal activities. So if you DD'ed lied about your condition HIPPA will not protect you. In the case of illegal pharmacies there would also be no HIPPA protections.
The DEA or prosecuting enity would maintain and review the list. Now in past cases they have sent letters asking for medical records and in a few cases asked people to testify.
Also I have seen people contacted by defense atty's asking to testify (Nations comes to mind).
Take care. Billylll
