In this episode, we get a primer on cannabis science with Zoe Sigman, program director of Project CBD and science editor of Broccoli Magazine.

Zoe guides us through the history of cannabis research, explaining how scientists discovered the endocannabinoid system (aka the ECS): the system in our body that interacts with cannabis. Basically…. WTF is the ECS? What else does it do? And do we even need weed in order to keep this system healthy? Zoe updates us on the latest science and explains what we're still learning/that there is still a lot to learn.

Plus: can we trust the claims being made by cannabis brands? Zoe untangles the complex relationship between regulations and research, and offers some tips on making educated choices.
