Understanding Terpenes

Terpenes are the natural scents and flavours in cannabis. They shape how each strain smells, tastes, and feels. This guide uses trusted science, and an interactive wheel.

What are terpenes?

Terpenes are natural chemicals made by plants, including cannabis. They give plants their smell and flavour. When you open a cannabis medicine and notice an earthy, citrus, or pine smell, that is terpenes at work.

Cannabis makes over 200 different terpenes (Booth and Bohlmann, 2019). Each strain has its own mix. That is why some strains smell like lemons, some like berries, and some like a damp forest. You find the same terpenes in everyday food: Myrcene is in mangoes, Limonene is in lemon peel, Linalool is in lavender.

Terpenes may also change how cannabis affects the body by working alongside cannabinoids like THC and CBD. Scientists call this the "entourage effect" (Russo, 2011).

The Entourage Effect

Think of a band. THC and CBD are the lead singers. Terpenes are the rest of the band. On their own each part is useful, but together they can make something richer and more powerful.

Dr Ethan Russo found evidence that terpenes can help cannabis work better for things like pain, anxiety, and sleep (Russo, 2011). Israeli researchers then showed that 16 cannabis terpenes can activate the same receptors in the body that cannabinoids use (Baram et al., 2022).
