Figure 3: Effect of route of administration on dose-normalized Cmax of THC, 11-OH-THC, COOH-THC, CBD, and CBN.

Figure 3:

Dose-normalized Cmax after administration of parent cannabinoid (THC, CBD, or CBN). 11-OH-THC and COOH-THC were measured after administration of THC via various routes; metabolite Cmax was normalized to the administered THC dose. Symbols represent mean values from individual studies (see Supplementary Table). Horizontal and vertical lines represent geometric means and corresponding 95% confidence intervals, respectively. Data were not available for CBN administered via oral mucosal spray.
