If you’ve ever looked at a cannabis product label, you likely noticed that it is VERY different from anything you’d find on food packaging. That’s because there are hundreds of different compounds present in the cannabis plant, each with its own potential experiences. However, one of the most confusing percentages found on marijuana labels is “TAC.”
We get plenty of questions about this number–specifically how it relates to THC. In this guide, we’ll explain:
- Total Active Cannabinoids (TAC): Everything You Need to Know
- Differences Between TAC and THC
- Impact of TAC on the Entourage Effect
- Frequently Asked Questions
TAC
Also: Total Active Cannabinoids
TAC indicates the total number of active cannabinoids present in the product. The term “active” refers to the cannabinoids in the product that have already undergone decarboxylation, or exposure to heat or light.
Total Active Cannabinoids (TAC): Everything You Need to Know
TAC–or total active cannabinoids–is a number you’ll often find on a cannabis product label that indicates the total number of active cannabinoids present in the product. The term “active” refers to the cannabinoids in the product that have already undergone decarboxylation, or exposure to heat or light. This is important because it determines the potency and overall effect of the cannabis products you consume.1
Still confused? Here’s even more detail about TAC.
What is a Cannabinoid?
Cannabinoids, technically called phytocannabinoids since they are plant derived, are the chemical compounds in cannabis that give it its unique effects. This includes THC, CBD, and more than 150 others! These compounds interact with your endocannabinoid system, a biological system in your body that regulates various physiological processes, including mood, memory, and pain perception.2
What is THC?
Tetrahydrocannabinol–i.e. THC–is the most well-known cannabinoid, recognized for its psychoactive effects. It binds to the body’s endocannabinoid receptors to produce the “high” associated with consuming cannabis. THC content is heavily regulated, with various laws determining the allowable limits in cannabis products and where it’s sold.3
What Cannabinoids Are Included In TAC?
TAC includes a variety of cannabinoids, each with its own properties and effects, that contribute to the overall experience of cannabis products.4 While there are hundreds that we know of, the most widely known include THC, CBD, cannabigerol (CBG), cannabichromene (CBC), cannabinol (CBN), and tetrahydrocannabivarin (THCV).
How Does TAC Measure Cannabis Potency?
TAC is a comprehensive measure of cannabis potency. By accounting for all the active cannabinoids, TAC provides a more accurate presentation of a product’s strength compared to focusing solely on THC. This can be particularly useful for consumers looking to understand the full potential effects of a product.5
Differences Between TAC and THC
Imagine that TAC is the whole symphony, while THC represents only one musician and their instrument. All the instruments playing together, or even in groups, produce different results than the solo musician.
TAC encompasses all active (decarboxylated) cannabinoids in a cannabis product, which provides a broader measure of its potency. In contrast, THC is only one cannabinoid and isn’t an accurate measure of a product’s strength–unless it’s a THC-only product and not a broad-spectrum one.6
Two products with the same THC percentage won’t yield the same effects because the other cannabinoids also contribute to the product’s potency and effects. It’s essential to look at a product’s TAC because it gives you a comprehensive understanding of what you consume.
Impact of TAC on the Entourage Effect
The entourage effect is the synergy or combined interaction between compounds, including cannabinoids and cannabis terpenes. TAC plays a significant role in this effect by providing a holistic look at the active cannabinoids, which can boost the overall experience and therapeutic benefits of cannabis products. Considering TAC when choosing products can help you manage and achieve the desired effects more effectively.
