eLife assessment
This important study presents the validation of an oral delta9-tetrahydrocannabinol (THC) consumption mouse model utilizing highly palatable e-capsule gelatin. The results convincingly demonstrate that oral consumption produced THC behavioral and physiological effects, as well as measurable brain levels. The utility of the model for chronic consumption remains to be determined. The authors have clearly acknowledged limitations of their model and areas for future study and development. As the field of cannabinoid research moves toward application of routes of administration that mimic human use, these model systems will be pivotal in assessing the effects of cannabinoid-based drugs.
