Open a jar of good craft flower and the first thing you notice is the smell. That smell is terpenes. They are the aromatic compounds the cannabis plant produces in its trichomes, the same sticky resin glands that hold THC and CBD. Pine, lemon, pepper, lavender, diesel, mango: every one of those notes is a terpene, or a blend of them.
Here is the short answer to the question most people are really asking. Terpenes are why two jars at the exact same THC percentage can smell and feel like different products. THC sets the intensity. Terpenes shape the character. They are not unique to cannabis either. The same compounds show up in citrus peel, hops, black pepper, and lavender.
What terpenes actually are
Terpenes are volatile oils, which is a fancy way of saying they evaporate easily and you smell them in the air. Cannabis makes dozens of them, but only a handful show up in large enough amounts to drive a strain's aroma. On a lab report you will often see the top three to five listed by percentage. Reading those is one of the most useful skills a shopper can pick up, because aroma is the most honest preview of what you are buying.
What are terpenes in cannabis?
Terpenes are the aromatic oils cannabis produces in its trichomes, the resin glands that also make cannabinoids like THC and CBD. They give each strain its distinct smell and flavor, from citrus to pine to pepper. The same compounds appear in many plants, including lemon peel, hops, and lavender.
The five you will see most
You do not need to memorize a chemistry chart. Learning five terpenes by their smell covers most of what you will meet on a NY craft menu.
- Myrcene: earthy and musky, a little like cloves or ripe mango. It is one of the most common terpenes in cannabis and is often associated with relaxed, heavy evening profiles.
- Limonene: bright citrus, the smell of fresh lemon or orange peel. Many people report an upbeat, clear-headed feel with limonene-forward strains.
- Caryophyllene: spicy and peppery, the same compound that gives black pepper its kick. It is the only terpene known to interact with the body's CB2 receptors directly.
- Pinene: sharp pine and fresh forest. It is the most common terpene in the plant kingdom and tends to read as crisp and alert.
- Linalool: soft and floral, the lavender note. It is often found in strains people reach for to wind down at night.
Terpenes and the entourage effect
The entourage effect is the idea that cannabinoids and terpenes work together, so the whole plant feels different from THC on its own. The term traces back to chemist Raphael Mechoulam in 1998. More recent research, including a 2021 University of Arizona study, suggests terpenes may modulate how cannabinoids behave at certain receptors. It is a promising area, but the science is still early and the synergy is not proven. Treat the entourage effect as a useful framework for choosing aroma profiles, not as a medical promise.
THC sets the intensity. Terpenes shape the character.
Do terpenes get you high?
No. Terpenes are not intoxicating on their own and do not produce a high the way THC does. They drive a strain's aroma and flavor and may influence the overall character of the experience. Cannabinoids like THC are responsible for intoxication. Effects may vary. Please consume responsibly.
How to use terpenes when you shop
Stop shopping by THC percentage alone. Look at the terpene list on the label, then ask your budtender to open the jar. If you like the smell, you will usually like the flower. Note which terpenes show up in the strains you already enjoy, and use that as a shortcut next time. A myrcene-and-linalool jar and a limonene-and-pinene jar are pointing you in genuinely different directions, even at the same potency.
At The Highline on Main Street in Hastings-on-Hudson, our roughly 40 craft cultivars come from independent upstate growers, and we can walk you through the terpene profile of anything on the shelf.
