Pupil diameter (A), latency (B), velocity of contraction (C), constriction time (D) and contraction amplitude (E) over time for the THC and the placebo group. Data reported are mean and 95% confidence intervals. Placebo group: n = 4 for all timepoints and all parameters; THC group for pupil diameter (A), latency (B) and constriction time (D): baseline n = 14, 20 min n = 10, 60 min n = 7, 120 min n = 10, 180 min n = 13, 240 min n = 12, 300 min n = 13; THC group for velocity of contraction (C) and contraction amplitude (E): baseline n = 14, 20 min n = 8, 60 min n = 7, 120 min n = 10, 180 min n = 13, 240 min n = 12, 300 min n = 13
