Study ends at 2.5 hrs post induction following the final blood draw. The psychologist will debrief subjects and will assess their affective state. Their subjective units of distress will be checked. Persons who are in a continued negative cognitive state will receive 30 minutes of Cognitive Behavioral Therapy (CBT) by the on-site psychologist. Care will be taken not to allow participants to leave the study site in distress. Participants will receive follow up psychology care at the CPC as indicated in their treatment plan.
