Understanding THC, CBD, and Ratio Products

THC and CBD are the two cannabinoids you will see most often, and knowing the basics makes shopping much easier.

The two you see most

THC is the compound most associated with the classic intoxicating effects of cannabis.

CBD is non-intoxicating and is often chosen by people who want to enjoy cannabis with a different, milder character.

Many products list both, and the balance between them is usually more informative than either number alone.

What the ratios mean

Ratio products are labeled with numbers like 1:1 or 2:1, telling you the balance of CBD to THC. A 1:1 product has equal parts of each. Higher-CBD ratios are popular with people who prefer a gentler experience, while THC-forward products lean toward stronger effects.

How to read a label

Look for four things:

1. Total THC and total CBD, usually as a percentage for flower or in milligrams for edibles.
2. The serving size, which matters enormously for edibles.
3. The ratio, if there is one.
4. The test date and lab, which every licensed product carries.

That last one is worth a moment. Everything on our shelves moves through the licensed supply chain, is tracked, and is lab tested against the state’s limits for pesticides, solvents, and microbial contaminants before it can be sold. Product that fails does not reach a shelf. That is the practical difference between a regulated shop and the alternative.

The entourage effect

THC and CBD get the headlines, but they are part of a much larger cast. Cannabis contains dozens of cannabinoids, plus terpenes and flavonoids, and there is a widely discussed idea called the entourage effect: the notion that these compounds work together, and that the whole is different from any single part.

Terpenes are the aromatic compounds that give a strain its smell. They are not unique to cannabis at all. The same families of terpenes give citrus its zest, pine trees their sharpness, and even black peppercorns their bite. Terpenes are not intoxicating, but aroma is powerful in its own right, the same way the scent of lavender is widely associated with a calm, settled feeling. Two products with the same THC number can smell and feel quite different depending on their terpenes.

Flavonoids are a third group, more associated with flavor, taste, and mouthfeel than aroma. They round out the character of a product.

Many people find that full-spectrum products, the ones that keep the plant’s natural range of compounds rather than isolating a single one, feel more rounded and even, even when they are potent. That is part of why the quality and cleanliness of a product matters as much as the number on the label.

Cannabinoids beyond THC and CBD

As the market matures, you will start to see lesser-known cannabinoids on labels. A few worth knowing by name:

• CBN appears as flower ages, when a portion of THC converts to it over time. You will see it listed on more labels than you used to.
• CBG is another minor cannabinoid attracting growing interest.
• THCV is a lesser-known compound that is currently an active area of research, and it behaves differently from THC in several ways.

These are areas of ongoing study rather than settled science, and nothing here is medical advice. If a particular product interests you, our team can tell you what is in it and how people tend to use it.

Two things that surprise people

How you take it changes the experience. Cannabis you eat is processed by your body differently from cannabis you smoke or vape, which is why edibles feel distinct and take longer to arrive. Our edibles guide covers that in detail.

Topicals with THC generally do not get you high. A balm or lotion works on the area you apply it to; the cannabinoids do not cross into the bloodstream in any meaningful amount. Transdermal patches are the exception, since they are designed to be absorbed, and they can be intoxicating. The label will tell you which you have.

Raw cannabis is not intoxicating. The plant produces THCA, the acid form of THC, which only converts when heated by smoking, vaping, baking, or cooking. That is why handling cannabis, or eating it raw, does nothing. Heat is the switch.

Where to start

If you are newer to cannabis or want something more balanced, a product with meaningful CBD alongside THC can be a comfortable place to start. Our Fairfax team is glad to help you compare options and find a ratio that fits.
