Brief Summary:
The purpose of this study is to investigate the effects of oral psilocybin in post-traumatic headache. Subjects will be randomized to receive placebo, low dose psilocybin, or high dose psilocybin on two separate test days approximately 14 days apart. Subjects will maintain a headache diary prior to, during, and after the treatments in order to document headache frequency and intensity, as well as associated symptoms. Blood samples will be drawn at various timepoints to measure levels of inflammatory peptides.

- Psychedelic effects using the 5-Dimensional Altered States of Consciousness (5D-ASC) scale [ Time Frame: Taken on each test day approximately 6 hours after drug administration ]94 questions scored 0 to 100 each; higher numbers indicate greater psychedelic effects Questions address 5 dimensions: (1) Oceanic boundlessness (score range 0-2700), (2) Dread of Ego Dissolution (score range 0-2100), (3) Visionary Restructuralization (score range 0-1800), (4) Auditory Alterations (score range 0-1600), and (5) Vigilance reduction (score range 0-1200) Score for each dimension as well as total score (range 0 to 9400) will be measured.
- Change in blood pressure [ Time Frame: Measured during each test session prior to drug administration, every 15 min in the first hour, every 30 min in the second hour, and then hourly for 4 hours or until resolution of psychedelic effects (~6 hours post drug) ]Maximum change from baseline during each test day (mmHg)
