A: The entourage effect, also known as the ensemble effect, is a term to describe: the synergy between cannabinoids and terpenes working together to create and magnify unique effects. 

The Entourage Effect = Cannabinoid Profile + Terpene Profile.
A combination (also known as a full-spectrum) of cannabinoids paired with terpenes will oftentimes help subdue negative side-effects too, smoothing out the “peaks and valleys” of user experience.  

An analogy about jet airplanes— cannabinoids are the “engine of the plane” and terpenes are the “pilot of the plane.” 
Airplanes differ and so do pilots but find the right combination and you’re in for a comfortable flight. 

If you don’t want to fly, that’s okay it’s just a metaphor.
