Bolded F values indicate p<0.05. Bold mean (SE) values indicate significant (p<0.05) post-hoc compared to placebo. Only individual adjective items with significant post-hoc results are shown. Only cognitive test outcomes with significant dose effects are shown. For each drug condition, n=12 except n=9 for dronabinol 30mg. P.O. indicates oral route.
