Mean subjective ratings ± standard error of the mean (SEM) for the Capsule Rating Form under placebo conditions (inactive cannabis + 0 mg oxycodone), and oxycodone (2.5 and 5.0 mg) and active cannabis administered alone or together. Significant differences from placebo are indicated by **, p ≤ 0.01, and ***, p ≤ 0.001; significant differences from active cannabis alone are indicated with #, p ≤ 0.05, ##, p ≤ 0.01, and ###, p ≤ 0.001.
