Comparison of the effect of increasing concentrations of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) (ng/ml) on blood elasticity (mPa·s). Blood was collected from the antecubital vein of 24 participants, and experiments were conducted in vitro. Values are expressed as means for plots (n = 24). The error bars represent the standard error of each mean (CBD, cannabidiol; THC, delta-9-tetrahydrocannabinol)
