What is the Entourage Effect? CBG, Terpenes, and Full-Spectrum Hemp

Where the entourage effect comes from

The term "entourage effect" was introduced by Israeli pharmacologist Dr. Raphael Mechoulam and colleagues in a 1998 paper studying endocannabinoid compounds. The central observation was that compounds present in the cannabis plant alongside the primary cannabinoids appeared to modulate their effects — not by acting as cannabinoids themselves, but by interacting with other receptor systems and influencing how the primary compounds behaved.

Since then, research into the entourage effect has expanded considerably, though it remains a hypothesis rather than a fully established mechanism. The clearest evidence exists for the interaction between terpenes and cannabinoids — not for any specific therapeutic claim, but for the general principle that compound combinations produce different experiences than single isolated compounds.

For CBG flower specifically, this means the 13.8% CBG in Stem Cell operates in the context of that strain's full terpene profile, minor cannabinoids, and flavonoids — not as an isolated molecule.

What terpenes are and why they matter

Terpenes are aromatic organic compounds produced by many plants — lavender, pine, citrus, black pepper, and hemp all produce terpenes. They are responsible for the distinctive smell of each plant. In hemp, terpenes are produced in the same trichomes that produce cannabinoids, which is why high-terpene flower and high-cannabinoid flower are often the same flower.

Terpenes are not intoxicating on their own. They do not bind to CB1 receptors and they do not get you high. What the entourage effect research suggests is that terpenes interact with neurotransmitter systems — including the endocannabinoid system — in ways that modify the overall experience of consuming the plant.

The most studied hemp terpenes include:

• Myrcene — The most common hemp terpene. Found in hops, mangoes, and lemongrass. Earthy, musky, herbal scent. Associated in research with relaxing character — myrcene is thought to enhance absorption of cannabinoids across the blood-brain barrier, though this mechanism is still studied.
• Ocimene — Sweet, floral, slightly herbal. Found in mint, parsley, and basil. Less studied than myrcene but present in notable quantities in lighter hemp strains.
• Pinene (alpha and beta) — The most widely occurring terpene in nature. Pine trees, rosemary, and basil. Sharp, clean, resinous scent. Alpha-pinene has been studied for its potential interaction with memory systems and as a bronchodilator.
• Linalool — Floral, lavender-adjacent. Found in lavender and many flowers. Often associated with calming character in aromatherapy research.

Terpene profiles: Stem Cell vs The White

The two Sober Sativas strains have meaningfully different terpene profiles, which contributes to their different character — not just in flavor, but potentially in the overall experience.

Terpene percentages vary by batch and growing season. Current batch data is available on our Compliance page.

Why whole-flower is different from isolate

CBG is available in multiple forms: isolate powder, oil tinctures, capsules, gummies, and smokable flower. The isolate and many processed formats strip out the terpenes and minor cannabinoids, delivering CBG as a single extracted compound.

Flower delivers none of that extraction. When you smoke or vaporize CBG flower, you are getting the whole plant — CBG, CBD, trace CBC, trace THC (below 0.3%), and the complete terpene profile the specific strain produced in that growing season.

The entourage effect theory argues that this matters — that the presence of myrcene, ocimene, and pinene alongside CBG creates an experience that is different in character from CBG alone. Research on this specific combination is limited, but the underlying principle (plant compounds interact) is well-supported.

For users who have tried CBD gummies or CBG capsules and felt nothing notable, whole-flower is worth trying. The delivery method (inhalation vs. digestion) is different, the onset is different (minutes vs. 30–90 minutes), and the compound profile is different. Many people who found edibles underwhelming report a more perceptible experience with flower.

The full-spectrum hemp picture

"Full-spectrum" is a term used to describe hemp products that retain the complete range of compounds present in the plant — all cannabinoids, all terpenes, all flavonoids. Full-spectrum products are distinct from:

• Broad-spectrum: All compounds retained except THC, which is removed via additional processing.
• Isolate: A single compound extracted and purified — everything else removed.

CBG flower is inherently full-spectrum. It is the plant in its natural state — dried, cured, and consumed. Nothing added, nothing extracted. The full spectrum of what the plant produced in that growing season is present in every bowl.

This is worth noting in the context of the November 2026 hemp regulations (P.L. 119-37). Many full-spectrum CBD products will face compliance challenges under the new total THC cap because their full-spectrum THC content is too high. CBG flower, which is naturally ultra-low in total THC, remains fully compliant as a full-spectrum product. See our legal guide for more on the regulatory landscape.

What this means for how you consume

If you care about the entourage effect, the practical implication is straightforward: consume the flower in ways that preserve the terpene profile.

• Dry herb vaporizer at lower temperatures (320–350°F / 160–177°C) preserves the most delicate terpenes, which volatilize at lower temperatures than cannabinoids. Higher temperatures release more cannabinoids but degrade lighter terpenes.
• Store properly. Terpenes are volatile. Exposure to heat, light, and air degrades the terpene content faster than the cannabinoid content. An airtight glass jar in a cool, dark location protects both.
• Do not grind too far in advance. Ground flower has significantly more surface area and off-gasses terpenes faster than whole buds. Grind immediately before use.
