Whether you’re new to the world of weed or a seasoned stoner, you’re probably familiar with the concept of cannabinoids, namely the two primary cannabinoids in cannabis: THC and CBD. These molecules receive the most attention because THC is typically the most potent part of many flower strains, and CBD is the star of high-CBD flower varieties and extracts alike.
But cannabis is so much more than its cannabinoids. In this post, we’ll dig deep into three key terpenes: limonene, myrcene and pinene. What’s a terpene? Glad you asked. Stick around and learn more about these potent aromatic compounds that give your favorite flower its signature aroma and nuanced effects.
What Are Terpenes?
Terpenes are fragrant molecules in cannabis, but they do more than smell good; they can actually shape your experience by interacting with cannabinoids. This is known as the entourage effect. By working synergistically with cannabinoids, terpenes can enhance therapeutic benefits and refine psychoactive effects.
Depending on the type and concentration of terpenes, they can modulate everything from mood to focus, offering a tailored journey with each inhale.
While we’re focusing on cannabis terpenes, they aren’t exclusive to the hemp plant. They can be found in citrus fruits, pine trees, lavender blossoms and all kinds of fruit, flowers and even herbs.
Limonene: Citrus Energizer
Limonene is a monoterpene abundant in the rinds of lemons, oranges and limes, as well as in rosemary and juniper. In the plant kingdom, limonene evolved to repel pests and lure pollinators with its vivid lemon-peel aroma.
In cannabis, limonene lends its citrus notes to certain strains’ aroma profile. Limonene can be preserved through careful extraction methods and proper curing techniques that minimize heat and oxidation. Proper handling during processing helps maintain the aromatic qualities that contribute to a strain’s overall sensory profile.
Mood and Benefits
A sunny lemon scent is associated with brightness and mood uplift. A recent study from Johns Hopkins researchers suggests that limonene can reduce some of the nervousness or paranoia commonly associated with THC consumption, without affecting the high.
Finding Limonene-Rich Strains
The amount of limonene in certain strains can vary by plant and by harvest. To ensure you’re getting a limonene-rich strain, choose products that have been lab-tested to confirm terpene concentration.
Myrcene: Relaxation Maestro
Myrcene is one of the most common terpenes in modern cannabis, characterized by an earthy, musky bouquet with hints of ripe mango and clove. It’s also found in hops, lemongrass and thyme, where it evolved as a defense against fungi and bacteria. Out of all the cannabis terpenes, myrcene is the most likely to be dominant in commercial strains. According to Leafly, if a consumer were to pick out a random flower in a legal state, the chances of it being myrcene-dominant are about 40%.
Mood and Benefits
Myrcene-rich plants like lemongrass have been used for pain relief and relaxation for centuries. In cannabis, myrcene’s reputation as a relaxant stands, though the effects are more anecdotal than scientific.
There have been some rodent studies that point to a strong connection between myrcene and sleep. Some research has also shown that myrcene could be used for pain management and even has antioxidant and antimicrobial benefits.
Finding Myrcene-Rich Strains
Seek out strains that list myrcene as a top terpene. Full-spectrum products, especially oils and tinctures, often preserve myrcene better than heat-exposed concentrates. If labels aren’t explicit, ask a knowledgeable budtender for products marketed as “earthy” or “clove-spicy.”
Many growers share terpene breakdowns on Leafly or manufacturer websites, so research before you buy to ensure your choice delivers that deep-relaxation effect.
Pinene: Forest-Fresh Focus
Pinene is the most abundant aromatic terpene in the natural world. It is found in orange peels, conifer trees, herbals like rosemary, dill, basil and parsley, and pine needles. Plants evolved pinene to deter herbivores and attract beneficial insects. Pinene is the second most common terpene found in cannabis flower, after myrcene.
Mood and Benefits
As with all terpene-related effects, the research is still in early stages. But pinene is thought to have anti-inflammatory, anti-anxiety and pain relief benefits. Pinene’s bronchodilator properties support clearer breathing and may counteract short-term memory fog, enhancing cognitive function.
Animal studies have indicated that pinene moderates memory impairment, suggesting potential for improved learning and recall.
Finding Pinene-Rich Products
Aim for products that list pinene among the top three terpenes. Raw terpene sprays or cold-extracted distillates often showcase pinene’s aroma without altering the flower’s flavor profile. For flower-lovers, seek growers who highlight “fresh-cut pine” or “forest-floor” in their product descriptions.
If you’re wondering about the terpene profile of a particular strain, ask your budtender to fill you in.
Frequently Asked Questions
How do I match a terpene to my intended activity?
Terpenes have been used for everything from relaxation to healing for centuries. When highlighted in different cannabis strains, they can have a unique effect on your high.
While each user will experience terpene effects differently, some have been shown to increase energy, while others are better for sleep and relaxation.
What’s the safest way to dose each terpene?
As with any substance or additive, start low and go slow. If a terpene-forward strain is new to you, try a small amount and wait at least 5 to 10 minutes before inhaling again. Pay attention to your body and how you feel before increasing your intake.
How should I store terpene-rich flower?
As volatile compounds, terpenes are especially sensitive to environmental factors like light and heat. The best way to store dried flower is in an airtight, opaque glass container kept in a cool, dark place. This preserves volatile oils and helps to maintain aroma and potency.
Can terpenes interact with medications?
Any form of cannabis has the potential to interact with both pharmaceuticals (including over-the-counter medications) and natural supplements. For example, limonene might change the rate at which the liver breaks down certain medications. Make sure to consult with your healthcare provider before using cannabis products, especially if you’re on prescription medications.
