Terpenes are the aromatic compounds that give cannabis its smell and flavor, and they may also influence how a strain feels. More than 200 terpenes have been identified in cannabis, ranging from citrus and pine to pepper and lavender. They form in the same resin glands that produce THC and CBD, so aroma and potency develop together.

What Are Terpenes?
Terpenes are volatile hydrocarbons built from repeating five-carbon units called isoprene. Plants use them to attract pollinators, repel pests, and shield tissue from heat and microbes. The same molecules show up in pine needles, citrus peel, hops, lavender, and black pepper.
Where Do Terpenes Come From in Cannabis?
Cannabis makes terpenes inside glandular trichomes, the tiny crystal-covered hairs on buds and leaves. Those trichomes also manufacture cannabinoids, which is why a sticky, fragrant flower usually signals a rich profile. Genetics set the baseline recipe, while light, temperature, nutrients, and harvest timing shift the final levels.
How Do Terpenes Interact With Cannabinoids?
Many consumers report that two strains with similar THC percentages feel different, and terpenes are one possible explanation. Scientists call this the entourage effect, the theory that terpenes and cannabinoids modulate each other's activity. Human clinical evidence is still thin, so treat bold marketing claims with caution.
Terpenes Explained: How They Work in Cannabis
Which Terpenes Are Most Common in Cannabis?
- Myrcene: earthy, musky, herbal; also found in mango and hops.
- Limonene: bright citrus; also found in lemon peel and orange rind.
- Pinene: sharp pine; also found in pine trees and rosemary.
- Linalool: soft floral; also found in lavender.
- Beta-caryophyllene: cracked pepper and spice; also found in black pepper and cloves.
- Humulene: woody and hoppy; also found in hops and sage.
- Terpinolene: complex, floral, and piney; also found in nutmeg and tea tree.
Do Terpenes Get You High?
Terpenes are not intoxicating on their own. They do not bind CB1 receptors the way THC does. They may still shape mood, alertness, or relaxation through other pathways, which helps explain why aroma feels like part of the high.
Do Terpenes Survive Heat?
Terpenes are volatile and evaporate at fairly low temperatures. Many begin to boil off between roughly 310 F and 390 F (155 C to 200 C). Gentle heat, low-temperature vaporizing, and sealed glass storage preserve more of the aroma profile.
How Do You Use Terpenes When Choosing Cannabis?
Smell the flower first, then read the terpene list on the label when one is printed. If you enjoy citrus and a lifted feel, limonene and terpinolene are common markers. If you want calm and body-heavy effects, myrcene and linalool appear often in those profiles.
Terpenes vs Cannabinoids: What Is the Difference?
Cannabinoids such as THC and CBD are the compounds most associated with psychoactive and therapeutic effects. Terpenes are the aromatic compounds responsible for scent and flavor. Both come from the same trichomes, so a full-spectrum product carries some of each.
Key Takeaways
- Terpenes create the smell and taste of cannabis.
- They are produced in trichomes alongside cannabinoids.
- They are not intoxicating by themselves.
- Aroma, storage, and heat all change the terpene profile.
