Key Takeaways:
- THC (tetrahydrocannabinol) is the primary psychoactive cannabinoid in cannabis. CBD (cannabidiol) is non-intoxicating. The ratio on a product label tells you how much of each is present relative to the other, always expressed as CBD:THC.
- Research published in the British Journal of Pharmacology found that CBD modulates the effects of THC by acting on overlapping receptor pathways, which is the scientific basis for why balanced-ratio products produce a characteristically different experience than straight-THC products.
- The most common ratios at cannabis dispensaries are 20:1 (CBD-dominant), 4:1, 2:1, and 1:1 (equal parts). High-THC products with no significant CBD are sometimes labeled as Type 1 or simply listed with THC percentage only.
- Minor cannabinoids including CBG, CBN, and CBC appear alongside THC and CBD on many product labels. Each interacts with the endocannabinoid system differently and contributes to the overall character of the product.
- Story Cannabis carries ratio products across all their dispensary locations, including Dialed In live rosin gummies, Wana gummies, Bits multi-cannabinoid gummies, CERTIFIED gummies, and Smokiez ratio options.

Most cannabis labels lead with a THC percentage. It is the most prominent number on the package, and for a long time it was treated as the only number worth knowing. But the legal market has matured, and a second number has become increasingly central to how consumers choose products: the ratio of CBD to THC.
Understanding that ratio is one of the most practical skills you can develop as a cannabis consumer. It changes how you read a menu, how you talk to a budtender, and how consistently you land on the experience you are actually looking for rather than the one you assumed you would get.
This guide covers what THC and CBD actually are at a molecular level, how they interact, what the different ratio categories mean in practice, how minor cannabinoids fit into the picture, and how to shop for ratio products at Story Cannabis locations in Arizona, Maryland, and Ohio.
What Are THC and CBD, and How Are They Different?
THC (tetrahydrocannabinol) is the primary psychoactive cannabinoid in cannabis. CBD (cannabidiol) is non-intoxicating. Although both are found in the cannabis plant, they interact with the body through different receptor pathways.
Cannabis contains over 100 identified cannabinoids. THC and CBD are the two most abundant and the most studied. They are chemically very similar, both derived from CBGA (cannabigerolic acid), the parent cannabinoid sometimes called the mother of all cannabinoids.
Despite that structural similarity, they interact with the body in meaningfully different ways.
A useful way to think about that difference is through a driving analogy: THC acts as the gas pedal, while CBD functions more like the brake.
THC: The Gas Pedal
THC binds directly to CB1 receptors in the brain and central nervous system. This direct binding is what produces the psychoactive experience cannabis is known for. The intensity scales with the amount consumed, your individual tolerance, the consumption method, and whether other cannabinoids are present alongside it.
Think of THC as the accelerator in the experience. More THC, more acceleration. The percentage on a label tells you the concentration in the product, not the total amount you will consume, which depends on how much of the product you use.
CBD: The Brake
CBD does not bind directly to CB1 receptors the way THC does, which is why it produces no psychoactive effect on its own. It interacts with the endocannabinoid system through indirect pathways and also acts on several non-cannabinoid receptor systems including serotonin (5-HT1A), vanilloid (TRPV1), and adenosine receptors.
When CBD is present alongside THC, it modulates how THC behaves. It does not cancel THC out, but it does change the character of the experience in ways that are now documented in peer-reviewed research.
A 2011 review in the British Journal of Pharmacology by Dr. Ethan Russo documented the evidence for synergistic interactions between cannabis compounds, including CBD’s modulation of THC’s receptor activity. This concept, often called the entourage effect, is the scientific basis for why ratio products produce a characteristically different experience than THC alone.
How Does the Endocannabinoid System Process THC and CBD?
The endocannabinoid system (ECS) is the reason cannabis affects the body at all. This internal signaling system helps regulate functions such as mood, appetite, memory, and pain perception. THC and CBD both interact with the ECS, but they do so in different ways, which helps explain why they produce distinct experiences.
The ECS is not a system that cannabis creates. It already exists within the body. Researchers first identified it in the early 1990s while studying how cannabis affects the brain and nervous system. The ECS consists of naturally occurring endocannabinoids, the receptors they bind to, and the enzymes that break them down. THC and CBD work by interacting with this existing network.
The key difference is where THC and CBD do most of their work. THC interacts strongly with receptors linked to its psychoactive effects, while CBD influences a broader mix of receptors throughout the body.
The receptor types below help explain why the two cannabinoids can create such different experiences:
- CB1 receptors: Concentrated in the brain and central nervous system. THC binds directly to CB1 receptors, driving its psychoactive effects. CB1 receptors are also involved in memory, pain signaling, appetite, and mood regulation.
- CB2 receptors: CBD interacts with CB2 receptors more than CB1 receptors and also influences several non-cannabinoid receptor systems. Caryophyllene, a common cannabis terpene found in spices like black pepper and cloves and various cannabis strains, also binds to CB2 receptors. That distinction makes it unique among cannabis terpenes because it can function similarly to a cannabinoid.
- Non-cannabinoid receptors: CBD acts on serotonin, vanilloid, and adenosine receptors, among others. This broader receptor profile is why CBD research has explored such a wide range of potential physiological roles.
When CBD is present alongside THC, it partially competes for some of the same receptor space and acts on overlapping pathways through different mechanisms. The combined product does not simply feel like THC plus CBD separately. The interaction produces a characteristically different experience than either compound alone.
What Each THC:CBD Ratio Tells You
THC:CBD ratios tell you how much CBD a product contains relative to THC. The first number represents CBD, and the second represents THC. A 1:1 ratio contains equal amounts of each cannabinoid, while a 20:1 ratio contains twenty times more CBD than THC.
Understanding the order is important because a 20:1 product is CBD-dominant, while a 1:20 product is THC-dominant. Getting this order wrong when reading a label leads to a very different experience than intended.
Reading the ratio is only the first step. The amount of CBD relative to THC can significantly influence how a product feels and who it may appeal to.
The most common ratio categories are outlined below:
20:1 and Higher: CBD-Dominant
At 20:1, CBD dominates by a wide margin. The trace amount of THC is typically below the threshold that produces noticeable psychoactive character for most people, though individual sensitivity varies. Products in this range are common in tincture and capsule formats. They are less common in flower or vape formats, since it is difficult to cultivate cannabis with a naturally high CBD:THC ratio that also produces compelling aromatic terpene profiles.
Consumers who are new to cannabis, who have a low THC tolerance, or who specifically want the full-spectrum character of a cannabis product with minimal psychoactive component often start in this range.
4:1 and 10:1: CBD-Forward, Low THC
These ratios carry enough THC to produce some psychoactive character, but the high CBD content significantly shapes that character. Consumers who find very high-THC products uncomfortable often find the 4:1 range more approachable. Wana produces a well-known 1:1 gummy available at Story locations; their 4:1 format appears on some menus as well.
The 4:1 ratio has become a standard benchmark for consumers transitioning from CBD-only products toward products with some THC, because the experience is meaningfully different from high-THC products without being as far removed as a 20:1.
2:1: Balanced, CBD-Led
A 2:1 ratio has twice as much CBD as THC. The psychoactive component is present and noticeable but modulated by the CBD content. This is a common ratio for consumers who want a functionally balanced experience rather than a strongly psychoactive one. Available in gummy, tincture, and some beverage formats.
1:1: The Balanced Ratio
The 1:1 ratio contains equal amounts of THC and CBD and has become one of the most recognized categories in cannabis retail. At this ratio, the interaction between THC and CBD is at its most direct. The experience is distinctly different from a THC-dominant product at the same dose and different again from a CBD-dominant product. Many consumers in the Story Cannabis community find it a useful middle ground after exploring other ratios.
Several products available at Story Cannabis locations showcase the 1:1 format and other balanced cannabinoid combinations:
- Wana Strawberry Lemonade 1:1 gummy: Each piece contains 5mg THC and 5mg CBD.
- Bits Elderberry Wellness (1:1 CBD): Each piece contains 5mg CBD and 5mg THC in a 20-count package.
- Dialed In Blood Orange Focus (1:1:1 CBC:THCV): This multi-cannabinoid live rosin gummy expands on the balanced-ratio concept by incorporating additional cannabinoids.
These products illustrate how the 1:1 format can serve as a foundation for both traditional THC ratios and more complex multi-cannabinoid formulations.
High THC (Type 1): Standard Cannabis
Most flower and many vape products on dispensary menus are Type 1, meaning they are high-THC with little or no CBD. These products are sometimes labeled as simply THC with a percentage, without a ratio, because the CBD content is too low to be meaningful in ratio terms.
Fade Co. flower, Rythm Live Resin, and most infused pre-rolls on the Story Cannabis menu fall into this category. For consumers who want the full terpene-forward experience of a specific strain without CBD modulation, Type 1 products are the appropriate choice.
THC:CBD Ratio Reference Guide
Ratio | CBD:THC | THC Character | Common Formats | Who It Tends to Suit |
|---|---|---|---|---|
20:1+ | CBD-dominant | Minimal to none | Tinctures, capsules | New consumers, low tolerance, CBD-focused |
10:1 | Strongly CBD-forward | Trace to mild | Tinctures, gummies | Low THC tolerance, CBD-forward preference |
4:1 | CBD-forward | Mild, modulated | Gummies, tinctures | Transitioning from CBD-only products |
2:1 | CBD-led balanced | Moderate, modulated | Gummies, beverages | Balanced experience, moderate consumers |
1:1 | Equal balance | Present, modulated | Gummies, tinctures, vapes | Experienced consumers seeking balance |
1:2+ | THC-forward | Pronounced | Gummies, tinctures | Experienced consumers wanting THC lead |
Type 1 | THC-dominant | Full psychoactive | Flower, vapes, pre-rolls, edibles | Experienced consumers, full THC experience |
Individual responses to cannabinoid ratios vary. These descriptions reflect general patterns, not guaranteed outcomes. Start at a low dose with any new ratio product.
What Are Minor Cannabinoids and How Do They Fit Into Ratio Products?
THC and CBD get most of the attention, but they are only two of the many cannabinoids produced by the cannabis plant. Minor cannabinoids such as CBG, CBN, CBC, and THCV also appear on product labels and can influence the overall character of a cannabis product.
The cannabis plant produces more than 100 cannabinoids. Most occur in much smaller amounts than THC and CBD, which is why they are classified as minor cannabinoids. Advances in extraction and formulation have made it easier for brands to include specific cannabinoids in ratio products, creating formulations that go beyond a simple THC balance.
Two products can have the same THC:CBD ratio and still produce different experiences. The reason often comes down to the additional cannabinoids in the formulation. Understanding the role of each of these four minor cannabinoids helps explain why:
- CBG (Cannabigerol): The precursor compound from which THC, CBD, and most other cannabinoids are derived. CBG interacts with both CB1 and CB2 receptors and is found in relatively small concentrations in most cannabis plants. Available in some specialty gummies and tinctures. Bits Yuzu Zone 1:1 CBG:THC (available at Story Cannabis Maryland) is a current example. Dialed In’s Rocket Berry 5:1 and Acai Berry 1:1:1 formats, available across Arizona, Maryland, and Ohio, also incorporate CBG alongside THC in their multi-cannabinoid rosin gummy lineup.
- CBN (Cannabinol): A mildly psychoactive cannabinoid that forms as THC degrades over time. Often associated with evening-use products in the retail market. The Bits Pomegranate R&R 1:1 CBN:THC (available at Story Cannabis Maryland), Wana Elderberry 2:1 THC:CBN (available at Story Cannabis Arizona, Maryland, and Ohio), and Smokiez Sour Mixed Berry 1:1 THC:CBN (available at Story Cannabis Arizona) are current examples.
- CBC (Cannabichromene): Non-intoxicating. Does not bind significantly to CB1 or CB2 receptors but interacts with other receptor systems including TRPV1. Found in Betty’s Eddies Cherry THC:CBD:CBC and Orange Creme 2:1:1 THC:CBN:CBC products at Story Cannabis Maryland.
- THCV (Tetrahydrocannabivarin): A minor cannabinoid structurally similar to THC but with different receptor activity at different doses. Found in small concentrations in some sativa-leaning strains and in a handful of specialty ratio products.
How to Read Multi-Cannabinoid Ratios on a Label
When a label shows a three-part ratio like 2:1:1 THC:CBN:CBC, read it as three separate cannabinoids listed in descending order of concentration. The product contains twice as much THC as either CBN or CBC, which are present in equal amounts.
How Multiple Cannabinoids Shape the Entourage Effect
Minor cannabinoid products are where the entourage effect concept becomes most practically relevant. The interaction between four or five cannabinoids produces a more complex profile than a simple two-compound ratio, and the research on these combinations is still catching up to what is commercially available.
How Do You Shop for Ratio Cannabis Products at Story Cannabis?
Ratio products are most commonly found in the edibles and tinctures sections of the Story Cannabis menu, both online and in-store. Most dispensary menus organize products by category, including flower, vapes, edibles, tinctures, pre-rolls, and concentrates.
While ratio products are most common in edibles and tinctures, flower is typically Type 1 with minimal CBD, and most vape cartridges follow the same pattern, though some brands produce 1:1 vape options.
When browsing online at StoryCannabis.com, the CBD content filter is one of the fastest ways to find ratio products. Sorting edibles by CBD content can quickly surface 1:1, 2:1, and higher-CBD options. You can also use the search bar with terms such as “1:1” to locate relevant products.
What to Ask Your Budtender
“Which gummies here have a 1:1 ratio?”
“Do you carry anything with a higher CBD content than THC?”
“What is the difference between the Wana 1:1 and the Bits 1:1?”
“Are there any 1:1 vape options currently in stock?”
“Which of your minor cannabinoid products would you recommend for someone new to ratios?”
How Do You Dose a Ratio Cannabis Product Correctly?
Dosing a ratio product follows the same basic principle as any edible: start low, wait for the effects to develop, and adjust gradually. One common misconception is that CBD neutralizes THC, making it safe to consume larger amounts. In reality, a 10mg THC 1:1 gummy still delivers 10mg of THC. The CBD may influence the overall experience, but it does not significantly reduce the THC dose.
When trying a new ratio product, follow these steps:
1. Start with 2.5mg to 5mg of THC
Begin in the same range you would use for any edible. If the lowest available option contains 10mg THC per piece, consider starting with half a gummy.
2. Wait for the Full Onset Window
Most edibles take between 30 minutes and 2 hours to take effect. Ratio products are not inherently faster acting than standard THC edibles unless they use nano-emulsification technology. Check the label before assuming a quicker onset.
3. Consider the Product Format
The delivery method can influence onset time. Tinctures taken sublingually (under the tongue) typically act faster than gummies because some absorption occurs through the mucous membranes. Fast-acting nano-emulsified gummies may also produce effects more quickly than traditional edibles.
4. Journal Your Response
Different ratios can produce different experiences. Keeping track of the ratio, THC dose, product type, and consumption setting can help you identify what works best for your preferences and tolerance level.
How Do You Read a Ratio on a Cannabis Product Label?
On licensed cannabis labels, ratios are most commonly expressed as CBD:THC, with CBD listed first. However, not all brands follow the same convention — some list THC first, and others use product-specific notation. Always check the label to confirm which cannabinoid each number refers to, since the order directly affects how you interpret the dose. Confirm the per-serving milligrams alongside the ratio, since the same ratio at different doses produces meaningfully different experiences.
When reading a ratio label, pay attention to three things:
- The ratio itself: 20:1, 4:1, 2:1, 1:1, or a multi-cannabinoid expression like 2:1:1 THC:CBN:CBC. Remember: CBD first, THC second.
- The per-serving milligrams: A 1:1 product at 2.5mg THC per piece is a very different starting point than a 1:1 product at 10mg THC per piece, even though both are technically the same ratio.
- The total package milligrams: A 100mg package that contains 20 servings is a 5mg-per-piece product. A 100mg package with 10 servings is 10mg per piece. Total package milligrams without knowing the serving count tells you nothing about dose.

Frequently Asked Questions
What does 1:1 mean on a cannabis product?
A 1:1 ratio means the product contains equal amounts of CBD and THC by weight. On a gummy labeled 1:1 with 5mg THC, there is also 5mg CBD. The CBD does not eliminate the psychoactive character of the THC, but research suggests it modulates how THC interacts with CB1 receptors, producing a characteristically different experience than a straight 5mg THC product. The Wana Strawberry Lemonade 1:1 gummy, available at Story Cannabis Arizona, Maryland, and Ohio, is one of the most widely stocked examples.
Does CBD cancel out the effects of THC?
No. CBD modulates THC’s interaction with CB1 receptors rather than blocking it entirely. The presence of CBD changes the character of the experience, but a 1:1 product with 10mg of THC still delivers 10mg of THC to your system. The often observed consequence is that a 1:1 product at the same THC milligram dose as a straight-THC product will provide a different experience, not weaker in all dimensions. Start at the same low dose you would with any edible product and adjust from there.
What is the difference between CBN and CBD?
CBD and CBN are both non-intoxicating cannabinoids, but they form through different processes and interact with the body differently. CBD is produced directly by the cannabis plant and does not bind significantly to CB1 receptors. CBN is produced as THC degrades over time, through oxidation, and is mildly psychoactive at higher doses. In ratio products, CBN is associated with evening-use formats, while CBD appears across the full ratio spectrum. Products like Wana Elderberry 2:1 CBN:THC, available at Story Cannabis, are built specifically around the CBN:THC pairing.
Which ratio is right for someone new to cannabis?
There is no universal answer, but a CBD-forward ratio is a practical starting point for consumers who have little or no prior cannabis experience. A 4:1 or 2:1 product at a low per-serving dose, 2.5mg to 5mg of THC, gives you the full-spectrum character of a ratio product with a more gradual introduction to THC’s psychoactive component. Starting with a Wana 1:1 at half the recommended serving, roughly 2.5mg THC and 2.5mg CBD, is another common approach. Ask your Story Cannabis budtender which specific ratio products are currently in stock and in the format that works for you.
