Fig. 4From: Measurement of Δ9THC and metabolites in the brain and peripheral tissues after intranasal instillation of a nanoformulationChanges over time of concentrations of Δ9THC and metabolites in the A blood, B plasma, C liver, and D urine. Two-way analysis ANOVA (metabolites vs time) was statistically significant for each panel (p=0.05) with metabolites accounting for the greatest percentage of total variance in levels of Δ9THC, Δ9THC-COOH, and Δ9THC-OHBack to article page
