What Are Terpenes? The Flavor and Aroma Compounds Behind the Plant

Think about stepping off a plane somewhere new. Before you see a single landmark, the air reaches you first: citrus and salt, pine and warm earth, something you can't name but recognize right away. Your nose has mapped the place before your eyes catch up.

That's terpenes. They aren't a cannabis trend. They're the chemistry that turns a place into a smell. If you've seen the word on labels and wondered what it means, this guide covers what terpenes are, the five you'll meet most often, whether they get you high, and why processing decides how many of them survive, which is the whole idea behind live resin.

Terpenes, Defined

Terpenes are aromatic compounds made by a huge range of plants. They come in sizes: monoterpenes are the smallest and most volatile, sesquiterpenes are heavier and more complex, and larger terpenoids go beyond those. The lighter the molecule, the faster it reaches your nose, which is why monoterpenes are what you smell the instant you peel an orange or crush a pine needle.

A review of plant essential oils notes that mono- and sesquiterpenes dominate the aroma of many plants. Lavender fields, pine forests and a ripe lemon all owe much of their scent to terpenes.

Cannabis is one of those plants, and an especially aromatic one. A 2025 review of cannabis aroma and flavor describes more than a hundred terpenes across varieties, with each cultivar's scent shaped largely by its genetics. In Highlandia terms, every region has its own weather, and terpenes are what that weather smells like. It's also why every can in the Highlandia THC drink lineup is made with CBDA live resin, an extract built to keep more of them. The same CBD live resin goes into Highlandia's 10mg THC gummies and 750 mL THC elixirs.

The Common Ones: Myrcene, Limonene, Linalool, Pinene and Beta-Caryophyllene

None of these is exclusive to cannabis. You've probably met all five before breakfast.

Terpene	Where else you smell it	Aroma notes
Myrcene	Hops, lemongrass, mango	Earthy, musky, slightly fruity
Limonene	Lemon and orange peel	Bright, fresh citrus
Linalool	Lavender	Floral, soft, slightly sweet
Alpha-pinene	Pine and other conifers	Fresh pine, resinous
Beta-caryophyllene	Black pepper, cloves	Spicy, woody, warm

Myrcene is among the most common terpenes in cannabis and part of what gives hops their earthy character. Limonene is the bright lift you get from scratching a lemon rind, linalool is a key part of lavender's scent, and alpha-pinene is the smell of a pine forest. Beta-caryophyllene is one of the main compounds in black pepper oil. These aromas feel familiar because they're everywhere in the food and plant world, long before they show up on a cannabis label.

Do Terpenes Get You High?

No.

THC acting on the brain's CB1 receptor is what produces cannabis intoxication, and common terpenes don't reproduce that. A 2020 study in Frontiers in Pharmacology found that cannabis terpenoids did not activate CB1 or CB2 receptors or change how THC acted at them in the models tested. A 2022 evaluation of terpenoid signaling at CB1 reached a similar conclusion in a neuronal model.

Some lab studies have reported interactions at high concentrations, and the research continues, but there's no human evidence that terpenes on their own are intoxicating. If you smell pine and feel something, that's the forest doing its job.

Terpenes vs Cannabinoids

Think of it this way: cannabinoids are the pharmacology, and terpenes are the geography.

Cannabinoids such as THC and CBD interact directly with the body's endocannabinoid system. Terpenes are mainly aromatic compounds; in nature they help plants attract pollinators, deter pests and respond to their surroundings.

Beta-caryophyllene is the interesting exception. Research published in PNAS in 2008 found that it selectively binds the CB2 receptor, which isn't the receptor behind intoxication. It's a common example of a dietary terpene with receptor activity, though human research on what that means is still limited.

The idea that terpenes and cannabinoids work together in ways greater than the sum of their parts has a name: the entourage effect. It's a big reason people seek out full-spectrum ingredients like live resin instead of isolates. The science is still developing, with some lab studies reporting interactions and others not, so we treat it as a promising idea rather than a proven effect. Our CBD + THC explainer covers how the cannabinoids in a Highlandia can relate to each other.

Why Most Edibles Lose Their Terpenes, and How Live Resin Keeps Them

Terpenes are volatile. That's what makes them aromatic, and it's also why they escape at almost every stage of processing.

Research on preserving terpenes in cannabis flowers describes substantial terpene losses during storage, with the lighter monoterpenes disappearing fastest. Drying and heat speed that up.

Distillation goes further. It separates cannabinoids from the lighter, more volatile parts of an extract, as research on wiped-film molecular distillation shows, leaving an oil with little of the plant's native aroma. That's why many edibles start from a neutral base and get their flavor from added ingredients. Our guide to distillate gummies vs live resin gummies looks at that choice in gummy form.

Live resin takes a different route: freeze at harvest, then extract cold. A 2021 study of a solventless method for fresh cannabis flowers found that working with fresh material at low temperatures preserved the plant's native terpene and cannabinoid profiles. Our distillate vs live resin comparison puts the two processes side by side.

What Live Resin Brings to a Drink

A drink built on distillate or isolate starts from a blank slate, and its flavor comes entirely from what's added. That's how many hemp beverages are made. A live resin input starts with more of the plant's native chemistry intact, which makes it a full-spectrum ingredient.

Highlandia's cans list "Hemp Derived CBDA Live Resin" on the ingredient panel. It supplies the CBD in every Highlandia can: the 5mg drinks (5mg THC + 2mg CBD per 7.5 oz seltzer, sold in 4-packs) and 50mg drinks like the Cottondew Clouds 50mg THC Drink (50mg THC + 2mg CBD per 12 oz can, sold in 4-packs), made with the live resin process that starts from fresh-frozen hemp. Our CBDA vs CBD guide explains why the label names the acid form.

The flavors are their own destinations: Rocket Peak is cherry, lime and blue raspberry, Cottondew Clouds is cotton candy and honeydew, and Tangilime Grove is tangerine and lime. All three medaled at the 2026 Summer PR%F Awards, with Rocket Peak taking Best in Show; our ranking of the best THC drinks of 2026 has the details. Each flavor is crafted to taste like its own corner of the map, with CBDA live resin in the formula to keep more of the plant's native chemistry in the can. Every batch is third-party tested, with results at coa.urb.shop.

Prefer a pour or a gummy? The same live resin is behind the CBD in Highlandia's 750 mL THC elixirs, Limoncello Coast (sun-soaked lemon, limonene's home turf), Goldentea Trails and Free Spirit, each at 10mg THC + 2mg CBD per 1.5 oz serving, and in its 10mg THC gummies, 10mg THC + 2mg CBD per piece from a whole plant extract.

Frequently Asked Questions About Terpenes

What are terpenes?

Terpenes are aromatic compounds made by many plants. They give citrus peel its brightness, lavender its floral scent and pine forests their unmistakable smell. Cannabis contains more than a hundred of them, and the mix varies by cultivar, growing conditions and how the plant is handled after harvest.

Do terpenes get you high?

No. Intoxication comes from THC acting on CB1 receptors. Common terpenes don't activate those receptors in standard lab tests, and there's no human evidence that terpenes on their own are intoxicating.

What's the difference between terpenes and cannabinoids?

Terpenes shape how a plant smells and tastes. Cannabinoids such as THC and CBD interact directly with the endocannabinoid system. Beta-caryophyllene sits in between: it's a terpene found in black pepper that binds the CB2 receptor without being intoxicating.

Why are terpenes in edibles often missing?

Many edibles start from distillate, a refined extract that loses most of its native terpenes along the way, and flavor is added back with food-grade ingredients. Live resin inputs start from fresh-frozen plants and keep more of the original aroma.

What is myrcene?

Myrcene is a monoterpene with an earthy, musky, slightly fruity aroma. It's found in hops, lemongrass and mango, and it's one of the most commonly detected terpenes in cannabis, though levels vary widely by cultivar.
