What Are Terpenes in Cannabis? Aroma, Flavor and Effects

Cannabis is a plant of many secrets, and one of its most aromatic lies in the terpenes. Terpenes are organic compounds found throughout the plant world, and in cannabis they define much of what makes each strain smell and taste the way it does. They’ve also caught the attention of researchers, who are studying whether terpenes shape how a strain feels, though that research is still early.

So What are Terpenes

Terpenes are not exclusive to cannabis; they contribute to the aromatic essence of many herbs, fruits, and flowers. In cannabis, these compounds are responsible for the plant’s distinctive smell and taste. Many people also notice that strains with different terpene profiles feel different, which is why budtenders often talk about terpenes when helping you choose.

A quick note before we dig in: most of what we know about terpenes and their effects comes from lab and animal studies or from what people report, not from large clinical trials in humans. Think of what follows as how people commonly describe these terpenes, not as health promises.

Terpenes People Reach for to Unwind

Myrcene, limonene, and linalool come up most often when people talk about relaxing. Myrcene has an earthy, musky scent and is commonly associated with a mellow, body-heavy feel. Limonene’s bright citrus aroma is often described as uplifting. Linalool, the floral terpene also found in lavender, is the one people tend to associate with calm. Researchers are studying all three, but the evidence in people is still limited.

Caryophyllene, Pinene and Myrcene

Caryophyllene stands out among terpenes because it can bind to CB2 receptors in the endocannabinoid system, which has made it a focus of research on inflammation. Pinene brings the fresh scent of pine forests, and myrcene the earthy notes found in mangoes and hops. Lab studies have looked at these terpenes for anti-inflammatory activity, but whether that translates into noticeable effects from a cannabis product isn’t yet clear.

Terpenes Associated With Evening Use

Myrcene, linalool, and terpineol are the terpenes most often found in strains people choose for the evening. Myrcene-forward strains are commonly described as heavy or relaxing, linalool brings a lavender-like aroma, and terpineol has a sweet, floral scent. If sleep is a concern, talk with a healthcare provider; for product questions, a budtender can point you to strains with these profiles. See also cannabis and sleep.

Limonene, Linalool and Caryophyllene

These three terpenes also show up in everyday foods: limonene in citrus peel, linalool in lavender and herbs, and caryophyllene in black pepper. That overlap is part of why a strain can smell like lemons or pepper. Research into their wider effects is ongoing.

The world of cannabis is complex and fascinating, with terpenes playing a central role in the unique character of each strain. As research continues, we’re likely to learn more about how terpenes and cannabinoids work together, the idea behind the entourage effect.

Quick Answers About Terpenes

Do terpenes get you high?

No. Terpenes aren’t intoxicating on their own. What they may do is shape how a product feels when they’re combined with cannabinoids like THC and CBD.

Do terpenes contain THC?

No. Terpenes and cannabinoids are both made in the plant’s trichomes, but they’re separate classes of compounds. Terpenes drive aroma and flavor; THC is the main psychoactive cannabinoid.

How many terpenes are there?

More than 200 terpenes have been identified in cannabis, and more than 20,000 across the plant world. A handful, like myrcene, limonene, linalool, caryophyllene and pinene, show up most often in cannabis.

What does “full spectrum” have to do with terpenes?

A full-spectrum extract is made from the whole plant, so it keeps the plant’s terpenes, flavonoids and minor cannabinoids alongside THC. See what full spectrum THC is.
