Cannabinoids 101: Understanding THC, CBD, CBG, CBN, CBC, and More

Cannabis labels can sometimes look like an alphabet lesson.

THC and CBD are familiar to many shoppers, but today’s menus may also mention CBG, CBN, CBC, THCA, CBDA, and other cannabis compounds. Understanding these abbreviations can help you read product information, compare options, and ask better questions during your next dispensary visit.

Cannabinoids are naturally occurring compounds found in cannabis. Researchers have identified many different cannabinoids, although THC and CBD remain the most extensively studied. Each compound has a different chemical structure and may interact with the body differently. However, research into many minor cannabinoids remains limited. (National Institute on Drug Abuse)

At Massachusetts Green Retail, we believe cannabinoid information should be useful—not overwhelming. Here is a straightforward introduction to some of the cannabinoids you may encounter while shopping.

THC: The Primary Intoxicating Cannabinoid

THC stands for tetrahydrocannabinol. When people describe the intoxicating or “high” effects associated with cannabis, they are generally referring to delta-9 THC.

THC can affect perception, coordination, memory, attention, and reaction time. The experience can vary considerably depending on the product, serving amount, method of consumption, individual tolerance, and other factors. (National Institute on Drug Abuse)

A higher THC percentage does not automatically mean a product is higher quality or that it will be the best option for every customer. Potency is only one part of the overall product.

When comparing cannabis, it can also be helpful to consider:

• Product format

• Serving size

• Terpene profile

• Cannabinoid balance

• Aroma and flavor

• Previous experience

• Personal tolerance

New or infrequent consumers should approach high-THC products carefully and begin with a low amount.

CBD: A Nonintoxicating Cannabinoid

CBD stands for cannabidiol.

CBD does not produce the same intoxicating effects associated with THC. It may appear in flower, edibles, tinctures, capsules, topicals, and products containing a combination of THC and CBD. (National Institute on Drug Abuse)

Products may be described using ratios such as:

• 1:1 THC to CBD

• 2:1 CBD to THC

• 5:1 CBD to THC

• CBD-dominant

• THC-dominant

A ratio tells you how the amounts of the two cannabinoids compare. For example, a 1:1 product contains approximately equal amounts of THC and CBD per labeled serving.

CBD is widely marketed for many purposes, but marketing claims often move faster than the available evidence. The FDA continues to identify unanswered questions about CBD’s safety, long-term use, drug interactions, and product quality. Customers should not assume that an over-the-counter or dispensary product has been proven to treat a medical condition. (U.S. Food and Drug Administration)

CBG: A Less Common Cannabinoid

CBG stands for cannabigerol.

The cannabis plant initially produces acidic cannabinoid compounds. One of them, CBGA, acts as a biological precursor used by the plant to form compounds that eventually become THC, CBD, and CBC. Heat can convert CBGA into CBG. (PMC)

CBG is typically present in smaller quantities than THC or CBD, although growers and manufacturers have developed products specifically marketed for higher CBG content.

You may find CBG in:

• Flower

• Gummies

• Tinctures

• Vape products

• Capsules

• Products combining CBG with THC or CBD

Research into CBG is growing, but much of the available evidence still comes from laboratory or animal studies. Early findings should not be treated as proof that CBG prevents, treats, or cures a health condition. (PubMed)

CBN: A Cannabinoid Associated With Aged THC

CBN stands for cannabinol.

CBN can form as THC changes through oxidation and degradation over time. This is one reason older cannabis may contain more CBN than freshly stored cannabis. Heat and storage conditions can also influence cannabinoid degradation. (PubMed)

CBN is frequently marketed in nighttime products, particularly gummies containing combinations of CBN, THC, CBD, or other ingredients. However, branding a product for nighttime use does not guarantee that it will produce a particular experience.

Research into isolated CBN remains much more limited than research into THC or CBD. Customers should be cautious of strong claims suggesting that CBN has been definitively proven to improve sleep or treat sleep disorders. (PMC)

CBC: An Emerging Minor Cannabinoid

CBC stands for cannabichromene.

CBC is another naturally occurring cannabinoid that may appear in small amounts in certain flower, extracts, and formulated products. It generally receives less consumer attention than THC, CBD, CBG, or CBN.

Scientists are studying how CBC interacts with different biological targets, but human research remains limited. A 2024 scientific review noted that commercial interest in CBC has expanded despite limited evidence regarding its safety and effectiveness. (PubMed)

For shoppers, CBC is best understood as another component of the cannabis plant—not as a guaranteed indicator of a particular benefit or experience.

THCA and CBDA: The Acidic Forms

Cannabis plants produce several cannabinoids first in their acidic forms.

Two abbreviations you may see are:

• THCA: Tetrahydrocannabinolic acid

• CBDA: Cannabidiolic acid

When exposed to sufficient heat, these acidic cannabinoids undergo a process called decarboxylation. THCA converts toward THC, while CBDA converts toward CBD. This conversion occurs during processes such as smoking, vaping, or controlled heating during manufacturing. (PubMed)

That is why flower labels may show both THC and THCA rather than displaying only one number.

Massachusetts testing protocols define a cannabinoid profile as including measured amounts of compounds such as delta-9 THC, CBD, THCA, and other cannabinoids. (Massachusetts Government)

What About Delta-8 THC?

Delta-8 THC is chemically related to delta-9 THC and may also produce intoxicating effects.

Many delta-8 products sold outside licensed dispensaries are made from hemp-derived CBD through chemical conversion. The FDA has warned that delta-8 THC products have not been evaluated or approved for safe use and has received reports of adverse events involving these products. (U.S. Food and Drug Administration)

Consumers should avoid assuming that a product is safe simply because it is labeled “hemp-derived” or is available outside a licensed cannabis retailer.

How to Read a Cannabinoid Label

When reviewing a cannabis package, look for information such as:

• Cannabinoid amount per serving

• Total cannabinoid amount in the package

• THC or THCA percentage

• CBD or CBDA percentage

• Ratios between cannabinoids

• Suggested serving size

• Testing and batch information

For flower, cannabinoids are commonly shown as percentages. Edibles and beverages usually display milligrams per serving and milligrams per package.

Always confirm whether a number refers to one serving or the entire container. A package containing 100 milligrams of THC may be divided into ten individually labeled 10-milligram servings.

Cannabinoids Are Only Part of the Product

Cannabinoid content can help you compare products, but it does not predict every aspect of the experience.

Two products with similar THC percentages can differ in aroma, flavor, terpene profile, cultivation quality, freshness, and format. Individual responses can also vary.

Instead of focusing on a single number, consider telling your budtender:

• Which formats you prefer

• Whether you are new or experienced

• What potency range you are comfortable with

• Whether you want THC-dominant, CBD-dominant, or balanced options

• Which aromas and flavors you enjoy

• What products you have previously liked or disliked

Research Status as of July 2026

Scientific knowledge about minor cannabinoids continues to develop. Information about CBG, CBN, CBC, and similar compounds may change as larger and better-controlled human studies become available. Early laboratory findings should not be interpreted as established medical benefits.
