THC vs. CBD: What’s the Difference?
THC and CBD are two of the most recognizable compounds found in cannabis—but they aren’t the same thing.
Both belong to a group of naturally occurring compounds called cannabinoids, yet they interact with the body differently. The biggest distinction is simple: THC can produce an intoxicating “high,” while CBD does not produce the same intoxicating effect.
Understanding the difference between THC and CBD can make cannabis labels, product descriptions and cannabinoid percentages much easier to understand.
What Are Cannabinoids?
Cannabinoids are chemical compounds produced by the cannabis plant.
Researchers have identified many different cannabinoids, but THC (tetrahydrocannabinol) and CBD (cannabidiol) are two of the best known.
Cannabinoids interact with a network in the human body known as the endocannabinoid system, which includes cannabinoid receptors and naturally occurring compounds produced by the body.
What Is THC?
THC, or tetrahydrocannabinol, is the primary intoxicating cannabinoid in cannabis.
In other words, THC is largely responsible for the “high” associated with cannabis.
Different cannabis products can contain very different amounts of THC. This is why looking at cannabinoid information can tell you more than simply seeing a strain labelled indica, sativa or hybrid.
Higher THC content doesn’t necessarily mean a product is “better.” It simply tells you something about its cannabinoid composition.
What Is CBD?
CBD, or cannabidiol, is another major cannabinoid found in cannabis.
Unlike THC, CBD does not produce the same intoxicating high.
Cannabis products can contain primarily THC, primarily CBD, or different ratios of the two cannabinoids.
You’ll often see these amounts or ratios displayed on cannabis product information.
THC vs. CBD: The Main Difference
The easiest way to remember the difference is:
THC is intoxicating. CBD is not intoxicating in the same way.
However, there’s more to cannabis than just THC and CBD.
Different varieties can contain different combinations of cannabinoids as well as aromatic compounds called terpenes.
This chemical composition is one reason two cannabis varieties with similar THC percentages may still have very different aromas and characteristics.
What Do THC and CBD Percentages Mean?
When looking at dried cannabis flower, you’ll often see THC and CBD expressed as percentages.
These numbers indicate the concentration of those cannabinoids in the product.
For example, two cannabis strains could both be labelled as hybrids while having very different THC and CBD concentrations.
This is another reason it’s useful to look beyond the traditional indica, sativa and hybrid labels when learning about cannabis.
Where Do THC and CBD Come From?
Here’s where those tiny crystals covering cannabis flower become important.
Cannabinoids and terpenes are produced in the plant’s glandular trichomes.
Trichomes are the tiny resin-producing structures that can give cannabis flower its frosty or crystal-covered appearance.

What About Terpenes?
THC and CBD aren’t responsible for everything you notice about cannabis.
The plant also produces terpenes, aromatic compounds that contribute significantly to the smell and flavour of different cannabis varieties.
Terpenes such as myrcene, limonene, pinene and caryophyllene can create earthy, citrus, pine, spicy and other distinctive aromas.
You can learn more in our What Are Terpenes in Cannabis? guide.
Is THC or CBD Better?
Neither cannabinoid is automatically “better.”
THC and CBD are different compounds with different properties. Cannabis products can also contain varying concentrations and combinations of cannabinoids.
Rather than judging cannabis solely by THC percentage, understanding its broader cannabinoid and terpene profile can give you a more complete picture of what’s actually in the product.
The Bottom Line
THC and CBD may come from the same plant, but they’re distinctly different cannabinoids.
THC is the primary intoxicating cannabinoid in cannabis, while CBD does not produce the same intoxicating high.
Learning to recognize cannabinoids, terpenes and trichomes can make cannabis labels and terminology much easier to understand—and that’s exactly what our Cannabis 101 series is here to help with.
