Terpenes vs cannabinoids: the short answer
Terpenes are the aromatic compounds that give cannabis its smell and flavor. Cannabinoids are the compounds that attach to receptors in your body, such as THC and CBD. Terpenes shape how a product smells and tastes. Cannabinoids shape how it feels.

Both come from the same plant and both show up on a lab report, but they are different molecules with different jobs. A strain can carry the same THC level as another and smell nothing like it, because the terpene mix differs.

What should you pick first?
Start with the cannabinoid ratio, then use terpenes to choose between products in the same range. Cannabinoid content is the part that sets intensity and direction of effect. Terpenes fine-tune aroma and, in some cases, the feel of the high.
terpenes explained chart
At Pop's Cannabis, that means reading the THC and CBD numbers before you open a jar. Once two options sit in the same range, pick the one whose terpene profile matches the smell you want.
- New user or low tolerance: start with a balanced or CBD-forward product.
- Daily smoker: pick by total THC, then choose a terpene profile you enjoy.
- Flavor chaser: put the terpene panel first, then confirm the cannabinoid numbers.
What are cannabinoids?
Cannabinoids are chemical compounds produced in the trichomes of the cannabis plant. The two on every label are THC (tetrahydrocannabinol) and CBD (cannabidiol), with CBG, CBC, and CBN in smaller amounts.
How cannabinoids work in the body
THC binds to CB1 receptors found in the brain and nervous system. That connection drives the psychoactive effect people call a high. CBD does not bind CB1 the same way and can temper some of the edge of THC.
CBG and CBN appear in smaller quantities. CBN forms as THC breaks down over time, so older flower can test higher for CBN and lower for THC.
What to read on a cannabinoid label
- Total THC: the main driver of intensity. On edibles, look at milligrams per serving, not the percentage alone.
- Total CBD: check the ratio. A 1:1 THC to CBD product feels milder than a THC-only product with the same THC dose.
- Minor cannabinoids: CBG, CBN, CBC. They matter at higher doses, and most flower carries them in small amounts.
What are terpenes?
Terpenes are volatile oils built from repeating carbon units. They evaporate at room temperature, which is why a fresh jar smells strong and an old one smells like hay.
More than 100 terpenes show up in cannabis, and a handful do most of the work. The mix, not a single terpene, creates the smell of a strain.
Common cannabis terpenes and their smells
- Myrcene: earthy, herbal, musky. Common in indica-leaning flower.
- Limonene: citrus peel. Found in many sativa-leaning strains.
- Pinene: pine needles and rosemary.
- Linalool: floral, lavender-like.
- Beta-caryophyllene: cracked black pepper and cloves. It also binds CB2 receptors in lab studies.
Breeders and extractors talk about a terpene profile the same way they talk about a cannabinoid profile. It is a fingerprint for the cultivar.
Do terpenes change the high?
Maybe. The entourage effect is the idea that cannabinoids and terpenes work together and produce a result that differs from THC alone. Human studies on this are thin, and most evidence comes from lab work and user reports.
What is well documented: terpenes drive flavor and smell, and smell shapes perception. Two products with the same THC can feel different when one tastes like citrus and the other like pepper, in part because aroma and expectation do real work.
Beta-caryophyllene is the strongest exception. It binds CB2 receptors in lab settings, which makes it more than a scent molecule.
Terpenes vs cannabinoids side by side
- Chemistry: cannabinoids are terpenophenolic compounds. Terpenes are hydrocarbons built from isoprene units.
- Role in the plant: cannabinoids are thought to defend against pests and UV light. Terpenes attract pollinators and repel plant eaters.
- Effect on you: cannabinoids bind receptors and drive the high. Terpenes shape aroma and may adjust the experience.
- Label numbers: cannabinoids show as percentages and milligrams. Terpenes show as percentages of the oil or flower and sit far lower than THC on the same report.
- Stability: cannabinoids hold up longer in storage. Terpenes fade with heat, air, and light.
Where the difference shows up in real products
In flower, both matter. You see cannabinoid percentages on the label and smell the terpenes through the jar. In vapes, the split is sharper: distillate carries cannabinoids and often added terpenes, while live resin keeps more of the plant's original terpene profile.
In edibles, cannabinoids do almost all the work. Terpenes burn off or get dosed too low to notice, and many gummies use added flavor instead. In topicals, cannabinoids act on skin and local receptors, while terpenes mostly add scent.
How to choose at Pop's Cannabis
Pick a cannabinoid target, then a terpene direction. These five routes cover most shoppers.
- Balanced 1:1 THC to CBD flower or vape. A good starting point for new users or anyone who finds high-THC products too much. Mild, clear, and hard to overdo.
- High-THC flower with limonene or pinene. For experienced users who want a citrus or pine aroma and a strong effect.
- CBD-dominant tincture or capsule. For people who want cannabinoids with little psychoactivity. Check total CBD per bottle, not just the percentage.
- Myrcene-heavy indica-style flower for evening. Earthy, herbal, and the usual pick for a slow night at home.
- Live resin or cured resin vape with cannabis-derived terpenes. More flavor than distillate with added botanical terpenes. Ask which one you are buying.
One warning: cannabis-derived terpenes and botanical terpenes are not the same. Botanical terpenes come from other plants and cost less. They smell sharp and can taste artificial in a vape.
Common questions about terpenes and cannabinoids
Is THC a terpene?
No. THC is a cannabinoid. It has no smell of its own in the way terpenes do.
Can terpenes get you high?
Not on their own. Terpenes are not psychoactive at normal doses. Products sold as terpene-only are flavor and aroma, not a high.
Why do two strains with the same THC feel different?
Terpene mix, minor cannabinoids, dose, and your own tolerance all play a part. THC percentage is one number, not the whole picture.
Do terpenes show up on a lab test?
Quality labs list them. Ask for the terpene panel if you want to compare two products beyond smell, and store your flower in a sealed jar away from light to keep those oils around longer.
