What is the difference between THC and TAC on weed labels?

In recent years, the cannabis market in the United States has skyrocketed. You can now choose from hundreds of marijuana products because marijuana is now legal in many jurisdictions and because demand is growing. Every time you visit a pharmacy you are surrounded by edibles, THC and CBD concentrates, pills and ointments all over the place. Knowing how to read product labels and understand THC levels will help you feel more comfortable.

Have you ever experienced information overload when reading cannabis labels like THC vs. TAC? After all, there are numerous abbreviations, percentages and intake techniques to learn and at first it may seem difficult to choose the right product. However, if you brush up on your basic cannabis knowledge, you will understand everything that the label on your product means.

The TAC number is perhaps the most important element on a cannabis label, even though THC and CBD are perhaps the two most well-known cannabinoids. What does TAC stand for specifically and why is it important? Does TAC make you higher too?


Total Active Cannabinoids or TAC is the term used to describe the number of active cannabinoids found in cannabis when analyzed in a laboratory. Cannabis contains a range of active ingredients, unlike medicines, which often have only one active ingredient.

Over 400 chemicals, including more than 100 cannabinoids, are believed to be present in marijuana (hemp and cannabis). They can be broadly grouped into the following categories: cannabinoids, terpenoids, flavonoids, alkaloids, and glycoproteins.

TAC, an indicator of the amount of all cannabinoids that make up a cannabis product, is used to measure its potency. Consider the following important cannabinoids:

Tetrahydrocannabinol (THC)

THC, often known as tetrahydrocannabinol, is the main ingredient in marijuana. In its active state, it is scientifically known as delta-9-tetrahydrocannabinol or delta-9-THC. Additionally, it leads to the ecstasy, or “high” associated with marijuana use. It is generally accepted that a high produced by high levels of THC is stronger than one produced by low levels of the active component.

Cannabidiol (CBD)

Next to THC, CBD is probably the cannabinoid that has the most popularity and demand. CBD may offer a range of health benefits, including reducing stress and inflammation. All of the CBD in your product is included in the TAC. Most importantly, unlike THC, CBD does not induce a high.

Cannabinol (CBN)

CBN is commonly referred to as the “sleep” cannabinoid. CBN is a non-intoxicating substance with a wide range of medicinal effects. Early studies suggest that cannabinol may improve sleep and reduce pain.

Cannabigerol (CBG)

Much like CBD might lessen the euphoric effects of THC, CBG has no intoxicating properties. Cannabis users can do this to reap the benefits of THC without experiencing strong highs.

This action of the endocannabinoid system may mediate this effect and may also be caused by CBG’s action on alpha-2-adrenergic receptors, which reduce the activity of the sympathetic nervous system.

Cannabichromene (CBC)

Although this substance has been known for 50 years, its benefits are still unknown. The fact that CBC, like THC and CBD, comes from cannabigerolic acids (CBGA) is well recognized. However, how the less popular cannabinoids affect human biology is not well understood.

Inexperienced professionals often mispronounce TAC as the Total Aerobic Count. The difference between it and Total Active Cannabinoids is that it alludes to a specific element of plant composition. You can determine the number of microorganisms in the cannabis sample by calculating the total aerobic count.


As the name suggests, TAC describes the chemical makeup of any cannabis or hemp plant, providing a list of the cannabinoids active in the plant. The total cannabis content of the product is therefore represented by TAC. TAC takes into account the full range of active cannabinoids present in the product, which is quite different from THC, which is just a cannabinoid.


There is a significant interaction between TAC and THC components. For example, CBD can reduce the anxiety caused by THC, thus altering the psychoactive effect as a whole.

Additionally, it’s important to remember that some TAC cannabinoids, like CBGA, aid in the synthesis of THC. Acidic CBGA, a type of CBG, breaks down into CBG and then breaks down even more into other cannabinoids like THC.


The synergistic interplay of terpenes, cannabinoids and flavonoids in cannabis is theoretically referred to as the entourage effect. Phytocannabinoids and terpenes, among other components of the cannabis plant, are said to mutually enhance their effects.

The TAC is crucial for the entourage effect. Still, fatty acids, flavonoids, and terpenes are other important chemicals that exist alongside cannabinoids. In addition, the entourage effect depends on all other connections, even if most of them are poorly understood.

Terpenes found in cannabis give each strain its own distinctive flavor. Terpenes are produced by all plants, fruits, and flowers, not just cannabis plants; They are a natural part of all plants. The terpenes limonene, linalool, pinene, and eucalyptol are some of the most popular. Terpenes can also have psychotropic effects, which explains why some terpenes have sedative properties.

But plant pigments come from flavonoids, which stand out as powerful antioxidants. Alongside this, there is still a need to study the process by which they contribute to the entourage effect.


TAC and THC are contrasted to see which is more beneficial or “greater” in terms of potency or purity. Instead, it suggests that when choosing a cannabis product, whether for medical or recreational use, you should definitely consider the percentage of TAC in addition to THC to make an informed choice. A more accurate picture of the overall cannabis product is the TAC percentage. But if strength is your first priority, you might want to opt for a product with a higher THC content. Of course, it’s important to remember that everyone’s reaction to cannabis is different, so start with a modest dose and gradually increase as needed.
