What Are Cannabis Terpenes? — Bangkok Guide
Open a jar of one strain and you'll get bright citrus; open another and it's diesel, pine, or sweet earth. That smell isn't random — it's terpenes, the aromatic compounds behind every strain's distinct character. Most people notice them without ever knowing the name. This guide covers what terpenes are, what they actually do, the main ones you'll come across, and why they matter so much in concentrates.
The basics
What Are Terpenes?
Terpenes are aromatic compounds found in cannabis and virtually all plant life. They're what give each cannabis strain its unique smell and flavour — the citrus, pine, fuel, berry, or earthy notes you pick up the moment you open a jar. They're also responsible for the scent of lavender, the zest of a lemon peel, and the sharpness of a pine forest.
In cannabis, terpenes are produced in the trichomes — the tiny, frosty resin glands on the flower — right alongside cannabinoids like THC and CBD. A single strain can contain dozens of different terpenes in varying amounts, and that specific blend is a big part of what makes one strain feel and taste different from the next.
Why they matter
What Terpenes Do — The Entourage Effect
Terpenes do more than shape smell and flavour — many believe they also influence the character of the experience. This idea is known as the entourage effect: the theory that cannabinoids and terpenes work together, each one shaping how the others are felt, rather than acting in isolation.
It's the most common explanation for something a lot of people notice — that two strains with nearly identical THC percentages can feel completely different. One might feel bright and social, another heavy and relaxing. The cannabinoid content is similar, but the terpene profile isn't. While research into the entourage effect is still developing, terpenes are widely regarded as a meaningful part of why each strain has its own personality.
Know your profiles
Common Cannabis Terpenes
Dozens of terpenes appear in cannabis, but a handful show up often enough to be worth knowing. Here are the most common ones and the characters they're typically associated with:
The most common cannabis terpene. Often associated with relaxing, heavy, body-focused effects.
Found in citrus peel. Commonly associated with uplifted, elevated mood.
Smells like a pine forest. Often linked to a sense of alertness and clarity.
Also found in black pepper. Notable as the only terpene that interacts with cannabinoid receptors.
The terpene behind lavender's scent. Frequently associated with calm and relaxation.
Multi-layered and hard to pin down. Found in many bright, uplifting strains.
Where it gets technical
Terpenes in Concentrates
Terpenes are delicate. They're volatile compounds that heat, light, and time break down easily — which is exactly why the way a concentrate is made has such a big impact on how it tastes and feels.
Live rosin and live resin are made from fresh-frozen flower specifically to capture the plant's full terpene profile before it degrades — which is why they're so prized for flavour. Distillate, at the other end, is refined to near-pure cannabinoid content, a process that strips terpenes out almost entirely. That's why distillate is nearly flavourless — and why producers often add terpenes back in afterward to restore taste and effect.
So when you taste a rich, flavourful extract versus a clean, neutral one, terpenes — or the lack of them — are usually the reason.
Added flavour
Reintroduced & Botanical Terpenes
When terpenes are added back into a product, they generally come from one of two sources:
- Cannabis-derived terpenes. Extracted from cannabis itself, these aim to recreate the original strain's profile as faithfully as possible. Generally considered the premium option.
- Botanical terpenes. Sourced from other plants but chemically identical to their cannabis counterparts. More accessible and widely used for flavouring and custom blends.
Both are used to restore flavour to distillate, customise vape cartridges, and craft specific aroma and effect profiles. Dedicated terpene products — like those from TrueTerpenes — let producers and enthusiasts fine-tune flavour and experience with precision, recreating well-known strain profiles or building something entirely new.
Terpenes are the aromatic compounds that give every cannabis strain its distinct smell, flavour, and — many believe — much of its character through the entourage effect. The main ones to know include myrcene, limonene, pinene, caryophyllene, linalool, and terpinolene. Because terpenes are delicate, extraction method matters: live rosin and live resin preserve them, while distillate strips them out and often has them reintroduced. Terpenes can be cannabis-derived or botanical, and dedicated terpene products let you fine-tune flavour and effect.
