01 / The essentials
What Is CBD? A Simple
Introduction to Cannabidiol
CBD stands for cannabidiol, one of the naturally occurring compounds called cannabinoids found in the cannabis plant. Hemp is a type of cannabis, and many consumer products use hemp-derived CBD extract.
CBD and tetrahydrocannabinol (THC) are different compounds. THC produces the characteristic cannabis “high”; CBD does not produce that same effect. However, a CBD product may also contain THC, and CBD itself can have side effects. The CDC’s CBD overview explains this distinction.
People commonly research CBD for questions about sleep, stress, discomfort, and general wellness. Interest in potential CBD benefits is not proof that a retail product will work for a particular concern. Research into CBD continues, and findings about prescription formulations should not be assumed to apply to every store-bought product.
CBD products come in oils, gummies, capsules, creams, and other formats. Understanding the format and the extract inside it gives you a useful starting point before comparing brands.

One compound. Different formats.
Popular types of CBD products, at a glance. The format describes how a product is made to be used; the spectrum describes its cannabinoid composition.
In focus
CBD Gummies
Flavored, chewable products with a labeled CBD amount per piece. Compare the serving definition, sugar content, ingredients, and extract type.
Explore CBD gummiesCBD Capsules
Capsules and softgels package a measured amount of CBD in a swallowable form. Check the capsule material, carrier ingredients, and CBD amount per unit.
CBD Topicals
Creams, balms, and lotions formulated for skin application. Review the complete formula, including fragrances and other active ingredients, and follow the product’s directions.
CBD Vape Products
Liquids and devices intended for inhalation. Vaping has distinct health risks; inclusion here is not a recommendation. Never put an oral CBD oil into a vape device.
CBD Isolate
CBD separated from other plant compounds, often supplied as a powder or incorporated into finished products. Isolate describes the ingredient, not a guarantee of final-product quality.
For inhalation safety context, see the FDA’s information on vaping-related lung injuries.

CBD Oil: What to Know
Before Choosing a Product
CBD oil combines a CBD extract with a carrier such as medium-chain triglyceride (MCT) oil, hemp seed oil, or olive oil. Hemp seed oil on its own is a different ingredient and should not be assumed to contain meaningful amounts of CBD.
Oils may use full-spectrum, broad-spectrum, or isolate-based extracts. Compare the formula alongside the bottle size: a larger bottle does not necessarily contain more cannabidiol, and a higher total does not always mean a stronger concentration.
A useful label states total CBD, volume, and CBD per serving. Match those figures to a current, third-party Certificate of Analysis (COA) for the same batch. A marked dropper can help interpret volume; drop size alone is not a reliable measurement.
04 / A closer look
CBD Gummies: A Convenient Way to Use CBD
CBD gummies are edible products made with cannabidiol and gummy ingredients such as pectin or gelatin. People often choose this format for its flavor, portability, and fixed amount per piece, without needing to measure a liquid.
That convenience makes the label especially important. “25 mg per serving” could refer to one gummy or several. Check the number of servings in the package, dietary requirements, and any added ingredients such as melatonin; these create a different formulation to assess.
Gummies can contain full-spectrum, broad-spectrum, or isolate-based CBD. The format does not tell you whether THC is present. Keep these products away from children and pets, since they can resemble ordinary candy.
05 / What’s in the extract?
Understanding the Types of CBD
Full-spectrum, broad-spectrum, and CBD isolate describe different compositions. No type is universally better; the actual formula and testing matter more than the label alone.
Full-Spectrum CBD
Retains a range of compounds from the plant, including other cannabinoids and terpenes. It generally includes some THC; the amount depends on the extract and finished product.
CBD + other plant compounds + THC
Broad-Spectrum CBD
Contains CBD and other plant compounds, with processing intended to remove THC. A “THC-free” claim needs checking against the laboratory’s results and detection limits.
CBD + other compounds · THC removed
CBD Isolate
Cannabidiol isolated from other cannabis compounds. It offers a simpler cannabinoid profile, but a finished product may still include carrier oils, flavors, or other active ingredients.
CBD separated from other plant compounds
Spectrum names are useful starting points, not proof of purity or a guarantee about drug testing. Read the batch report and the CDC’s guidance on possible THC exposure.

How to Evaluate
CBD Products
Good research starts with information you can check. Use the same questions across CBD brands to make differences easier to see.
A COA is a test report, not an endorsement. It describes a tested sample and does not establish medical effectiveness or guarantee every aspect of safety.
Check concentration
Separate total extract weight from actual CBD content. Compare milligrams per serving and the number of servings, alongside your preferred format.
Read every ingredient
Look for carrier oils, sweeteners, allergens, fragrances, and added actives. A short front label rarely tells the full story.
Find the batch COA
Match the batch number and date. Review cannabinoid results and whether testing covers pesticides, heavy metals, microbes, and residual solvents.
Trace the source
Look for the hemp’s origin and a disclosed extraction method. CO₂ or ethanol extraction alone does not prove quality; the finished-product report matters.
Compare real value
Divide price by total milligrams of CBD for a useful comparison within similar products. Factor in testing, ingredients, shipping, and subscription terms.
Look behind the brand
Check accessible contact details, clear policies, and explanations of testing. Be cautious of medical promises or reports that cannot be matched to a product.

Building a Better
CBD Directory
In development · listings coming laterCBD Index is being developed into a structured CBD directory for brands, products, communities, publications, and educational resources. Today, this guide helps you build the knowledge to research them.
The planned CBD products directory will organize oils, gummies, capsules, and topicals around useful details such as format, ingredients, extract type, and available testing information. Community and website listings will explain their focus and intended audience.
The aim is context you can use, beyond a collection of links. Directory listings are not available yet, and inclusion in a future index should not be read as a medical endorsement.

A few things
you might be wondering.
Clear answers to common CBD questions, all in one place.
Back to the essentialsWhat is CBD?
CBD is cannabidiol, a cannabinoid found in cannabis, including hemp. Unlike THC, it does not produce the characteristic cannabis high. That distinction does not mean CBD is free of side effects or suitable for everyone.
What is CBD oil?
CBD oil combines CBD extract with a carrier oil, such as MCT or hemp seed oil. Compare the CBD amount per milliliter, the extract type, ingredients, and a batch-specific laboratory report. Hemp seed oil alone is not the same product.
What are CBD gummies?
CBD gummies are edible gummies formulated with cannabidiol. Labels usually state a CBD amount per gummy or serving. Check how many pieces make up a serving, plus sugar, allergens, other active ingredients, and reported THC content.
Does CBD contain THC?
CBD itself is a different molecule from THC, but a CBD product may contain both. Full-spectrum extracts generally include THC. Even products labeled THC-free can be mislabeled or contain traces, so a label cannot guarantee a negative drug test.
What is the difference between full-spectrum and broad-spectrum CBD?
Full-spectrum CBD retains a range of plant compounds, generally including some THC. Broad-spectrum CBD is processed to remove THC while retaining other compounds. Check the actual laboratory results because terminology alone does not establish a product’s composition.
What is CBD isolate?
CBD isolate is cannabidiol separated from other cannabis compounds. It may be sold as a powder or used in oils, gummies, and other formulations. An isolate-based product still needs ingredient checks and laboratory testing.
How should I compare CBD products?
Start with the same format and extract type, then compare CBD per serving, ingredients, batch-matched testing, and price per milligram of CBD. Read the full report rather than relying on a tested badge. A higher concentration does not automatically mean a better fit.
What will the CBD Index directory contain?
The planned directory will cover CBD brands, products, communities, publications, educational resources, and related websites. Listings are not live yet. The current homepage provides a guide to product formats, extract types, and useful research questions.
