If you have ever noticed that two strains with the same THC percentage feel completely different, you have experienced something that researchers have been studying for nearly three decades. The theory behind this phenomenon has a name: the entourage effect. It suggests that the full spectrum of compounds in cannabis, from cannabinoids like THC and CBD to terpenes, flavonoids, and other plant molecules, work together to shape the experience in ways that no single compound can replicate on its own.
For consumers shopping at licensed dispensaries in New York, understanding the entourage effect can change the way you think about choosing flower. Instead of chasing the highest THC number on the menu, you start paying attention to the full chemical profile of a strain, and that shift can lead to a much more satisfying experience.
Where the Idea Came From
The term "entourage effect" was coined in 1998 by Israeli researchers Raphael Mechoulam and Shimon Ben-Shabat. Mechoulam, widely regarded as the father of cannabis science, had already identified THC as the primary psychoactive compound in cannabis decades earlier. But his later work revealed something important: isolated THC did not always produce the same effects as whole-plant cannabis. Something else in the plant appeared to be modifying and shaping the experience.
Mechoulam and Ben-Shabat proposed that the many secondary compounds in cannabis, particularly terpenes and minor cannabinoids, act as a supporting cast that modulates how THC and CBD interact with the body's endocannabinoid system. The whole plant, they argued, is greater than the sum of its parts.[1]
What the Latest Research Says
For years, the entourage effect remained more of a theoretical framework than an established scientific fact. That has started to change. A wave of recent research is providing new evidence that terpenes do more than contribute aroma and flavor.
A 2021 study published in Scientific Reports found that several common cannabis terpenes, including alpha-humulene, beta-pinene, linalool, and geraniol, exhibited what researchers called "cannabimimetic" properties. In cell-based assays, these terpenes selectively enhanced cannabinoid activity, suggesting they may amplify or modulate the effects of THC and CBD at a cellular level.[2]
In 2025, a team of researchers in Israel reported that multiple cannabis terpenes activated both CB1 and CB2 cannabinoid receptors in a dose-dependent manner. This was significant because earlier studies had questioned whether terpenes could interact with these receptors at all. The Israeli findings suggest that terpenes may not just support cannabinoids indirectly, but may also engage the endocannabinoid system on their own.[3]
A comprehensive review published in early 2025 in Pharmaceuticals examined the accumulated evidence and concluded that while large-scale human clinical trials are still needed, it would be "premature to deny the existence of either pharmacodynamic or pharmacokinetic interactions among active compounds present in cannabis."[4] In other words, the scientific community increasingly acknowledges that these interactions are real, even if the precise mechanisms are still being mapped.
The Terpenes at the Center of the Conversation
Not all terpenes appear to contribute equally to the entourage effect. Research has highlighted several that seem to play particularly important roles in how cannabis interacts with the body.
Beta-Caryophyllene
This is the most well-established terpene in the entourage effect conversation. Beta-caryophyllene is unique among terpenes because it directly binds to CB2 cannabinoid receptors, the same receptors targeted by certain cannabinoids. Research suggests it may produce anti-inflammatory and analgesic effects without any psychoactive properties, making it a compound of significant therapeutic interest.[5] You will find caryophyllene in many Greenline strains, including Blue Dream and Deep Space, where it contributes warm, peppery notes.
Myrcene
Myrcene is the most abundant terpene in cannabis. It carries an earthy, musky aroma and is associated with sedating, relaxing effects. Research suggests that flower with elevated myrcene levels is associated with greater perceived symptom relief among patients.[6] In the context of the entourage effect, myrcene may help explain why certain indica-leaning strains produce such pronounced body relaxation.
Pinene
Alpha-pinene and beta-pinene are found across many plant species and give cannabis strains their fresh, piney character. A 2025 analysis reported that beta-pinene acts as a partial agonist on CB1 and CB2 receptors, opening new avenues for understanding how this terpene contributes to the overall cannabis experience.[3] Early research also suggests pinene may support alertness and memory retention, which could help balance the cognitive effects of THC.[7]
Linalool
The same terpene that gives lavender its calming character, linalool was among the terpenes that showed cannabimimetic activity in the 2021 Scientific Reports study.[2] Research suggests it may support relaxation and calm mood, and its presence in the entourage may enhance the soothing properties of cannabinoids. Strains like Sugar Breath feature linalool prominently in their terpene profiles.
Limonene
A 2024 Johns Hopkins clinical trial found that limonene, the citrusy terpene found in many sativa-leaning strains, reduced self-reported anxiety in participants who consumed THC alongside it. The study was among the first controlled human trials to examine individual terpene-cannabinoid interactions, and its findings support the idea that specific terpenes can meaningfully shape the cannabis experience.[8] We covered this study in detail in our post on cannabis terpenes and anxiety.
Why This Matters When Choosing Flower
The practical takeaway from the entourage effect is straightforward: THC percentage alone does not tell you how a strain will feel. Two strains at 25% THC can produce very different experiences depending on their terpene and minor cannabinoid profiles.
This is especially relevant in New York's maturing cannabis market, where consumers have more options than ever. As of early 2026, the state has surpassed $3.3 billion in cumulative legal cannabis sales with over 600 licensed dispensaries operating statewide. With that kind of selection, understanding what drives the effects you enjoy gives you a real advantage.
When browsing the menu, consider these practical steps. First, look beyond THC percentage. A strain at 21% THC with a rich, diverse terpene profile may deliver a more nuanced and enjoyable experience than a strain at 30% THC with a thinner chemical profile. Second, pay attention to dominant terpenes. If you want relaxation, look for myrcene and linalool. If you want energy and focus, pinene and terpinolene are good signals. If you want potential anti-inflammatory support, caryophyllene is the one to watch. Third, choose whole-plant flower. The entourage effect is most relevant to full-spectrum products like whole flower, where the complete chemical profile of the plant is preserved. Heavily processed concentrates and isolates may strip away the terpenes and minor cannabinoids that contribute to this synergy.
What Still Needs to Be Studied
Intellectual honesty matters here. While the evidence for the entourage effect is growing, the science is not yet settled. Most of the research to date has been conducted in cell-based or animal models, and the handful of human trials, like the Johns Hopkins limonene study, are small in scale. The cannabis research community broadly agrees that more rigorous, large-scale clinical trials are needed before the entourage effect can be considered fully proven.
There is also an important nuance: some studies have found no significant direct interaction between certain terpenes and cannabinoid receptors.[9] This does not disprove the entourage effect, as the interactions may occur through other biological pathways, but it does highlight that the mechanisms are more complex than a simple "terpenes boost THC" narrative.
What consumers can take from the current state of research is this: the chemical diversity of cannabis flower matters. Whether through direct receptor binding, modulation of cannabinoid metabolism, or other pathways yet to be fully described, the terpenes and minor cannabinoids in your flower are likely contributing to your experience in meaningful ways.
The Bottom Line
The entourage effect represents a shift in how we think about cannabis quality. It moves the conversation beyond potency alone and toward the richness and complexity of the whole plant. For consumers in New York, this means looking at the full picture when selecting flower: the terpene profile, the minor cannabinoid content, and the overall chemical diversity of the strain.
At Greenline Apothecary, every strain in our lineup is chosen for its complete terpene profile. We believe great flower is about more than just THC, and the emerging science supports that perspective.

Frequently Asked Questions
What is the entourage effect in cannabis?
The entourage effect is the theory that the full spectrum of compounds in cannabis, including cannabinoids like THC and CBD alongside terpenes and flavonoids, work together to produce effects that differ from any single compound acting alone. The idea was first proposed by researchers Raphael Mechoulam and Shimon Ben-Shabat in 1998.
Do terpenes activate cannabinoid receptors?
Recent research suggests they might. A 2021 study published in Scientific Reports found that several common cannabis terpenes, including myrcene, pinene, and linalool, produced cannabimimetic effects and selectively enhanced cannabinoid activity in cell-based assays. A 2025 study from Israel reported dose-dependent activation of both CB1 and CB2 receptors by cannabis terpenes. However, some earlier studies found no direct terpene interaction with these receptors, so the science is still evolving.
Which terpenes contribute to the entourage effect?
Several terpenes are thought to play a role. Beta-caryophyllene is the most established, as it directly binds to CB2 cannabinoid receptors. Myrcene, pinene, linalool, and limonene have also shown potential interactions with the endocannabinoid system in recent studies. Each terpene may contribute different modulatory effects, from calming to energizing.
Is the entourage effect scientifically proven?
The entourage effect is a well-supported hypothesis, but it is not yet considered fully proven by scientific consensus. There is growing evidence from cell-based studies and some clinical research, but large-scale human clinical trials are still needed. Researchers generally agree it would be premature to dismiss the concept, given the multiple biological activities attributed to cannabis terpenes and minor cannabinoids.
How do I choose cannabis strains for the entourage effect?
Look for whole-plant, full-spectrum flower with a rich terpene profile rather than focusing solely on THC percentage. Strains with diverse terpene profiles, including combinations of myrcene, pinene, caryophyllene, and linalool, may offer a more complete experience. Checking the Certificate of Analysis (COA) for terpene content is the best way to evaluate a strain's chemical diversity.
