Cannabinoids Guide
Cannabinoids are the active chemical compounds in cannabis that interact with your body's endocannabinoid system. THC and CBD are the most common, but the plant makes over 100, including CBG, CBN, and CBC. Each behaves differently, and together they shape a product's commonly reported effects.

So what exactly is a cannabinoid?
A cannabinoid is one of the active chemical compounds cannabis produces. They interact with receptors in your body's endocannabinoid system, which influences things like mood, appetite, and sleep. THC and CBD are the headliners, but the plant makes more than 100 cannabinoids in varying amounts.
Think of the cannabis plant as a small chemistry set. Alongside cannabinoids, it produces terpenes, the aromatic compounds that give each strain its smell. Cannabinoids are the part most people are asking about when they want to know how a product will feel.
NIDA, part of the National Institutes of Health, identifies THC as the main psychoactive compound and notes the plant contains more than 100 cannabinoids total. Most are present in trace amounts.
Your body has its own endocannabinoid system with receptors that these plant compounds latch onto. That interaction is why cannabinoids do anything at all, and why dose and product format change the outcome.
THC vs CBD, the two everyone knows
THC is the cannabinoid responsible for the high people commonly report. CBD is non-intoxicating and does not produce that effect. Many products list both, and the ratio between them is one of the first things a Rezidue budtender will point you toward when matching a product to what you want.
THC, short for tetrahydrocannabinol, is what most people mean when they talk about getting high. According to NIDA, it acts on receptors concentrated in brain regions tied to memory, coordination, and time perception.
CBD, or cannabidiol, does not cause intoxication. People often reach for CBD or balanced THC-to-CBD products when they want something milder. If you are weighing the two, our THC vs CBD guide goes deeper.
A product labeled, say, 1:1 has roughly equal THC and CBD. A high-THC, low-CBD product tends to feel more intense. Neither number alone tells the whole story, which is where the rest of the cannabinoid and terpene profile comes in.
The minor cannabinoids: CBG, CBN, CBC and more
Beyond THC and CBD, the plant makes smaller amounts of compounds like CBG, CBN, and CBC. Research on these minor cannabinoids is still early, so any effects are commonly reported rather than medically established. They show up increasingly on labels and in specialty products.
CBG, cannabigerol, is sometimes called a precursor compound because other cannabinoids form from its acidic version as the plant grows. It usually appears in small quantities.
CBN, cannabinol, forms as THC ages and oxidizes, which is why older flower can show more of it. Some people seek out CBN products in the evening, though the human evidence is limited.
CBC, cannabichromene, is another minor cannabinoid under active study. The honest framing for all of these is curiosity, not certainty. At a licensed shop, you can read the verified panel before deciding.
Why raw flower is mostly THCA, not THC
Fresh cannabis flower contains very little active THC. It is rich in THCA, the acidic precursor, which converts to THC only when heated. This decarboxylation is why a label can show high THCA next to low THC, and why you smoke or vape flower rather than eat it raw.
When you apply heat by smoking, vaping, or baking, THCA loses a carbon-dioxide molecule and becomes the THC that produces effects. CBDA converts to CBD the same way.
This explains a label that confuses a lot of first-timers: a flower package might read 24 percent THCA and under 1 percent THC. The activated potency comes from the THCA figure once heat does its work.
Edibles are made with already-activated cannabinoids, which is part of why they hit differently. For the full breakdown, see our THCA vs THC explainer.
How cannabinoids and terpenes work together
People often report that cannabinoids and terpenes shape the experience together rather than in isolation. That idea is commonly called the entourage effect.
It is a popular framework, not a settled medical fact, but it is useful when choosing products. Reading both the cannabinoid panel and the terpene list gives you a fuller picture than chasing a single THC number.
How to read cannabinoids on a New York label
In New York, licensed dispensaries must sell lab-tested products with a Certificate of Analysis. The label and COA show the cannabinoid profile, total THC, CBD, and often minor cannabinoids. Those tested numbers, required by the NY Office of Cannabis Management, are what you should trust over marketing.
The NY Office of Cannabis Management requires adult-use products to be tested and labeled. That testing is the source of every cannabinoid figure on the package.
Look for total THC and total CBD first, then any minor cannabinoids listed. The COA also screens for contaminants, which is one reason buying from a licensed shop matters.
If a product anywhere claims big numbers with no testing behind it, treat that as a red flag. OCM publishes the official licensed-retailer list at cannabis.ny.gov.

- THCA and CBDA: acidic precursors common on raw flower labels
- Minor cannabinoids: CBG, CBN, CBC where present

NIDA and NIH on how cannabinoids act in the body
The National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, describes cannabis as containing more than 100 compounds called cannabinoids, with delta-9-tetrahydrocannabinol (THC) identified as the main psychoactive component. NIDA explains that THC acts on cannabinoid receptors found on nerve cells throughout the brain and body, part of the endocannabinoid system the body produces naturally. According to NIDA, the highest density of these receptors sits in regions that influence memory, coordination, pleasure, and time perception, which helps explain why effects vary by region and dose. NIDA notes cannabidiol (CBD) does not produce the intoxication associated with THC. This receptor-level framing, rather than any single marketing claim, is the accurate way to understand why two products with similar THC numbers can feel different.
FDA on cannabis-derived cannabinoid status
The U.S. Food and Drug Administration (FDA) maintains that, apart from a small number of specific prescription medications, it has not approved cannabis or most cannabinoids for the diagnosis, cure, mitigation, treatment, or prevention of any disease. The FDA has approved one CBD-based prescription drug for certain rare seizure disorders and a small set of synthetic THC-related drugs, but it stresses that adult-use dispensary products are not FDA-evaluated medicines. The agency also cautions that cannabinoid content on labels is not always verified outside of regulated testing programs. For a New York shopper, the practical takeaway is to rely on a product's Certificate of Analysis and the state's testing requirements rather than treating any cannabinoid as a medical remedy. Rezidue frames all cannabinoid effects as commonly reported, never as treatment.
NY Office of Cannabis Management on testing and labeling
The New York Office of Cannabis Management (OCM), the state body created under the Marijuana Regulation and Taxation Act (MRTA) of 2021, requires that adult-use products sold at licensed dispensaries be lab tested and labeled. That testing is where the cannabinoid numbers on a package, total THC, CBD, and often minor cannabinoids, come from. OCM rules mean a product at a licensed retailer like Rezidue carries a Certificate of Analysis verifying its cannabinoid profile and screening for contaminants. The agency publishes the official licensed-retailer list at cannabis.ny.gov, and only OCM-licensed dispensaries may legally sell these tested products. For anyone trying to understand cannabinoids in practice, the COA is the document that turns plant chemistry into the verified numbers you actually buy.
Peer-reviewed consensus on THCA and decarboxylation
A broad scientific consensus, reflected across peer-reviewed cannabis chemistry literature, holds that raw cannabis flower contains very little active THC. Instead it is rich in tetrahydrocannabinolic acid (THCA), the acidic precursor. THCA converts to THC through decarboxylation, a reaction driven by heat, which is why smoking, vaping, and cooking activate the intoxicating effect that raw flower does not produce. The same acid-to-neutral relationship applies to CBDA and CBD. This is why a flower label may list a high THCA figure alongside a small THC figure, and why edibles are made with already-activated cannabinoids. Understanding decarboxylation is central to reading a label correctly. Rezidue budtenders point shoppers to the THCA-versus-THC distinction so the potency line on a package makes sense before purchase.

NIDA on CBN, minor cannabinoids, and degradation
NIDA and the broader research community recognize that THC and CBD are only the best-studied members of a much larger cannabinoid family. Minor cannabinoids such as cannabigerol (CBG), often called a precursor compound, cannabinol (CBN), which forms as THC ages and oxidizes, and cannabichromene (CBC) appear in smaller amounts and are areas of ongoing study rather than settled effect claims. Researchers note that the human evidence base for most minor cannabinoids remains limited, so reported effects should be treated as preliminary and individual. For a shopper, the honest framing is that minor-cannabinoid products are interesting and increasingly available, but their benefits are commonly reported rather than medically established. Rezidue stocks products with verified cannabinoid panels so you can see exactly which compounds, and how much, you are buying.
What are cannabinoids?
Cannabinoids are the active chemical compounds in cannabis that interact with the body's endocannabinoid system. THC and CBD are the most familiar, but the plant produces more than 100, including CBG, CBN, CBC, and the acidic forms THCA and CBDA. Each interacts with receptors differently.
What is the difference between THC and CBD?
THC is the main intoxicating cannabinoid, responsible for the high people commonly report. CBD is non-intoxicating and does not produce that effect, according to NIDA. Many people choose CBD or balanced THC-to-CBD products for a gentler experience. Both are tested and labeled at licensed New York dispensaries.
How many cannabinoids are in cannabis?
NIDA describes cannabis as containing more than 100 cannabinoids. Only a handful, mainly THC and CBD, are well studied. Minor cannabinoids like CBG, CBN, and CBC appear in smaller amounts and are active areas of research, so their effects are commonly reported rather than medically established.
What is THCA and why is it on my label?
THCA is the raw, acidic precursor to THC found in unheated flower. It converts to active THC through decarboxylation, which heat triggers when you smoke or vape. That is why a flower label can show high THCA alongside low THC. For a deeper breakdown, see Rezidue's THCA vs THC guide.
Are minor cannabinoids like CBN and CBG worth trying?
They can be, but the science is still early. CBN forms as THC ages, and CBG is often called a precursor compound. Human research on minor cannabinoids is limited, so any benefits are commonly reported, not proven. At Rezidue, products show verified cannabinoid panels so you know what you are buying.
How do cannabinoids work in the body?
NIDA explains that cannabinoids act on receptors in the endocannabinoid system, found on nerve cells throughout the brain and body. The densest receptor regions affect memory, coordination, and time perception, which helps explain why effects shift with dose, product, and the cannabinoid involved.
Are cannabinoid products tested in New York?
Yes. The NY Office of Cannabis Management requires adult-use products at licensed dispensaries to be lab tested and labeled with their cannabinoid profile. That testing produces the Certificate of Analysis you can review. Rezidue, at 723 11th Ave in Hell's Kitchen, sells only OCM-tested products to adults 21+.
Where can I learn how cannabinoids work together?
Cannabinoids and terpenes are often discussed together because people report they interact. Rezidue's guide to the entourage effect covers that idea in plain English, and our strains pages explain how cannabinoid and terpene profiles shape the experience you might choose.
