CBD vs CBG vs CBN: A Shopper's Guide

For a long time, cannabis shopping was mostly about THC percentages. In the last few years, minor cannabinoids — the other molecules in the plant that do interesting things — have gone from footnotes to real product categories. Vermont dispensaries now carry products specifically formulated around CBD, CBG, CBN, and increasingly CBC and THCV.

Here's what they actually do and how to shop for them.

CBD (cannabidiol)

The most studied minor cannabinoid. Non-intoxicating — CBD alone will not get you high. It's associated with anti-inflammatory effects, anxiety reduction, pain modulation, and some sleep benefits. CBD is legal in all 50 states when derived from hemp, and the cannabis version (from cannabis sativa above the 0.3% THC threshold) is sold at dispensaries.

Typical formulations:

• CBD-dominant flower: Strains like ACDC, Harlequin, Cannatonic. High CBD, low THC, minimal psychoactive effect.
• 1:1 ratios: Equal parts CBD and THC. Mellower high, less anxiety, often used medicinally.
• CBD tinctures: Sublingual oil, 15–30mg CBD per dropper. Slow, stable effect.
• CBD topicals: Creams and balms for localized pain. These don't cross into the bloodstream at intoxicating levels.

CBD works best when given time and a reasonable dose — 15–50mg daily for anxiety, higher for pain. One-off 10mg doses often don't do much. Our ACDC strain page covers one of the most common CBD-dominant cultivars.

CBG (cannabigerol)

Known as "the mother cannabinoid" because it's the precursor to THC and CBD in the plant. As the plant matures, most CBG converts into other cannabinoids, so mature flower is typically CBG-low. CBG-dominant strains are bred specifically to halt this conversion early.

User-reported effects: focused, clear-headed, gently uplifting. Non-intoxicating or very mildly so. CBG is often marketed for focus, mood support, and daytime use. Early research suggests anti-inflammatory and neuroprotective properties, but the evidence base is much thinner than for CBD or THC.

Typical formulations:

• CBG tinctures: Often blended with CBD.
• CBG-dominant flower: Rare but emerging — White CBG, Jack Frost CBG. Tastes different, smokes clean, no high.
• CBG + CBD daytime gummies: Popular format for "functional" cannabis — designed for focus, not intoxication.

CBN (cannabinol)

CBN is what THC becomes when it ages and oxidizes. Old, degraded cannabis has more CBN than fresh cannabis. This is why some people report that old-stash flower hits heavier and more sedating — the THC has partially converted.

Reported effects: sedating, sleep-inducing, mildly intoxicating in higher doses. CBN is the cannabinoid most associated with sleep products — "CBN sleep gummies," "CBN night tinctures," etc. The research is still thin on whether CBN itself is responsible for the sleep effect or whether it's the combination of CBN with small amounts of THC and terpenes.

Typical formulations:

• CBN sleep gummies: Often 5mg CBN + 2.5mg THC per gummy. Widely available at Vermont dispensaries.
• CBN tinctures: Usually taken 30–60 min before bed.
• CBN + melatonin combos: Stacked with other sleep aids.

Note: CBN products often contain small amounts of THC. Check the label. If you're sensitive to THC or drug-tested, CBN-only (zero-THC) products exist but are less common.

CBC (cannabichromene)

Much less common, not typically called out in Vermont products yet. Early research suggests anti-inflammatory and mood-related effects. If you see it listed, it's usually as a minor component of a full-spectrum product.

THCV (tetrahydrocannabivarin)

Interesting emerging cannabinoid. In low doses, appears to be appetite-suppressing and mildly stimulating (nicknamed "diet weed" in some circles, which is overselling it). In higher doses, psychoactive. African landrace sativas — Durban Poison, some Malawian strains — naturally contain elevated THCV. Specific THCV-dominant products are rare but starting to appear.

The "full-spectrum" question

Most of the most-reported cannabis benefits seem to come from the interaction of multiple cannabinoids and terpenes — the "entourage effect." Isolated single cannabinoids (pure CBD, pure CBN) can work, but full-spectrum products — which contain the full matrix of the plant's cannabinoids and terpenes — tend to be more effective for many users.

When shopping: "full-spectrum" on a tincture label means the product contains the complete range of cannabinoids from the source plant. "Broad-spectrum" usually means full spectrum minus THC. "Isolate" means a single cannabinoid, nothing else.

How to shop by goal

• Anxiety, day-to-day calm: Start with CBD tincture, 15–25mg, daily for 1–2 weeks. Build up if needed.
• Pain, inflammation: CBD + a small amount of THC often works better than CBD alone. Topicals for localized pain, tinctures for systemic.
• Sleep: CBN + THC gummies, or a 1:1 tincture 30–60 min before bed.
• Focus, mood lift without intoxication: CBG-dominant product, often in tincture or gummy form.

What to ignore

Marketing that makes medical claims ("cures anxiety," "treats insomnia") without evidence. Cannabinoid research is real but young; most claims are extrapolated from small studies. Keep expectations modest and build up dosing gradually.

And: products that list only a strain name without cannabinoid percentages. Minor cannabinoid content is not visible in the smell or the color. Ask for lab results. Vermont dispensaries are required to have them on file.
