Subjects will need to provide a urine free of all illicit drugs other than cocaine and marijuana at study onset to be randomized. Subjects who test positive for any drugs other than marijuana prior to a study session will be allowed a single retest and a chance to reschedule their session. If the subject tests positive for any drug other than marijuana at the retest, their participation in the study will be terminated.~3. Subjects who meet current or lifetime DSM-IV criteria for bipolar affective disorder, schizophrenia, or any psychotic disorder~4.

Patients with impaired renal function, as indicated by corrected creatinine clearance below 60 ml/min as determined by the modified Cockcroft equation (CDC, 1986).~14. An unacceptable liver panel or liver function tests (LFTs) that may be indicative of hepatic dysfunction.~15. Clinical laboratory tests (e.g., complete blood count (CBC), blood chemistries, urinalysis) outside normal limits, as determined by the study PI.~16. History of significant heart disease or dysfunction (e.g., an arrhythmia which required medication, Wolff Parkinson -White Syndrome, angina pectoris, documented history of myocardial infarction, heart failure).~17. Electrocardiography (EKG) indicative of 1st degree heart block, sinus tachycardia, left-axis deviation, non-specific ST or T-wave changes.~18.

Study Arms:
- Placebo Session 1, Aprepitant Session 2 (Type: EXPERIMENTAL): Participants receive placebo in session 1 and Aprepitant in session 2 of a psychological stressor presentation and receive placebo in session 1 and Aprepitant in session 2 of a physiological stressor presentation. Participants take Aprepitant (80 mg) or placebo tablets for 7 days prior to each session.
- Placebo Session 1, Placebo Session 2 (Type: PLACEBO_COMPARATOR): Participants receive placebo in session 1 and placebo in session 2 of a psychological stressor presentation and receive placebo in session 1 and placebo in session 2 of a physiological stressor presentation. Participants take placebo tablets for 7 days prior to each session. The placebo group is used for analysis purposes in order to control for any order effects found in the Experimental group.

Based on this trial design, predict the completion outcome and termination type (if applicable).
