Cannabis Terpenes: The Complete Guide [2024]

Cannabis terpenes are aromatic compounds found in the resin glands of cannabis plants, contributing to the unique cannabis plants smell, flavors, and potential therapeutic effects associated with different cannabis strains.

As the cannabis industry continues to evolve, understanding terpenes has become crucial for both consumers and producers seeking to optimize their cannabis experience.

What Are Cannabis Terpenes?

Terpenes are naturally occurring chemical compounds produced by a wide variety of plants, including cannabis. In cannabis plants, terpenes are primarily synthesized in the trichomes – the tiny, crystal-like structures on the surface of cannabis flowers and leaves.

The primary functions of terpenes in nature include:

• Protecting plants from predators and environmental stressors
• Attracting pollinators
• Regulating plant growth

In marijuana plants, terpenes not only contribute to their unique aromas but also play crucial roles in repelling pests and enhancing the plant’s immune system.

In cannabis, terpenes work synergistically with cannabinoids like THC and CBD to produce what’s known as the “entourage effect” – the theory that cannabis compounds work better together than in isolation.

Terpene Biosynthesis in Cannabis

The cannabis sativa plant produces terpenes through two main biochemical pathways:

1. The methylerythritol phosphate (MEP) pathway
2. The mevalonate (MVA) pathway

These pathways convert simple organic molecules into the building blocks of terpenes – isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Specialized enzymes called terpene synthases then catalyze reactions to form the diverse array of terpenes found in cannabis.

The Most Common Cannabis Terpenes and Their Effects

While cannabis contains hundreds of terpenes, a select few appear in significant concentrations and contribute notably to the plant’s effects. Here are some of the most prevalent and well-studied cannabis terpenes:
