Cannabis glossary
Plain-language definitions of the cannabis terms you'll see on labels, menus, and across our guides.
- Anandamide
- One of the body’s own endocannabinoids, sometimes called the "bliss molecule," that THC partly mimics.

- Cure
- The slow post-harvest process of storing dried flower to develop aroma and smoothness.
- Dab
- A small dose of concentrate vaporized at high heat, potent, and not a beginner’s method.
- Decarboxylation
- Heating cannabis to activate THC, why raw flower must be heated to have an effect.

- Endocannabinoid system
- The body’s own signalling network that cannabis interacts with, regulating mood, appetite, sleep and more.
- Entourage effect
- The theory that cannabinoids and terpenes work together, shaping effects more than THC alone.
