Cannabis reduction rates determination outcomes.

Assessment	Active (%)	SE	Lower 95% CI	Upper 95% CI	Sham (%)	SE	Lower 95% CI	Upper 95% CI	Mann–Whitney U, p-value
GPD	57.97	16.31	26.00	89.95	42.58	17.41	14.14	83.19	U = 30, p = 0.561
NarcoCheck (ng/mL)	43.78	15.18	14.03	73.53	18.75	23.02	−26.98	69.84	U = 33, p = 0.473

Reduction rates are comparing Baseline to Day 28 completers resulting in active n = 9; sham n = 8. A negative reduction rate is indicative of increased cannabis use. The table provides the test statistic, U statistic, as well as the asymptotic significance (2-tailed) p-value.
