Below is a YouTube playlist (40 minute total) I put together to help make the biology of cannabis easier to understand (I hope). 

It discusses:

- The Endocannabinoid System (our bodies produce some cannabinoids and we have receptors)

- Cannabinoids (e,g, THC, CBD, CBG, CBN)

- Terpenes (smelly but healthy)

- The Entourage Effect (different components complementing one another)
