TAC vs THC: A Comprehensive Comparison

The world of cannabis is vast and complex, with many terms and acronyms that can be confusing to newcomers and experienced users alike. Two such terms are TAC and THC. While THC (tetrahydrocannabinol) is a well-known component of cannabis, TAC (Total Active Cannabinoids) is a broader term that encompasses more than just THC. Understanding the differences between TAC and THC is crucial for anyone interested in the effects and benefits of cannabis. This comprehensive comparison will clarify these concepts and explore their implications for selecting the best weed strains.

What is THC?

Tetrahydrocannabinol or THC is the thing in cannabis that gets people high. When people talk about getting high they are usually talking about THC. It works by attaching to something called CB1 receptors in the brain and the rest of the body. This is what causes the feelings people get when they use cannabis.

THC is not just for getting high. Scientists have found that it can also be used for reasons.

What THC does in your body:

  • Triggers psychoactive effects: this includes feeling happy seeing things differently and feeling relaxed because it affects the CB1 receptors in the brain
  • Relieves pain: some people use THC of regular pain medicine for pain that will not go away or for pain caused by damaged nerves
  • Stimulates appetite: doctors sometimes tell patients to use THC if they are not eating enough because they are sick or because they have an eating problem
  • Reduces nausea: a time ago doctors started using THC to help people who were sick to their stomachs especially people, with cancer
  • Supports sleep: some people use THC to help them sleep if they have trouble sleeping because they are stressed out or because they have insomnia

What is TAC?

TAC stands for Total Active Cannabinoids. It is not a thing. It is a measure.TAC tells you how much of every cannabinoid is in a cannabis product. All these are added together to make one number.

Think of it like this: THC is one ingredient. TAC is all the ingredients together.

What TAC includes:

  • THC (Tetrahydrocannabinol) — the psychoactive compound responsible for the “high”
  • CBD (Cannabidiol) — non-psychoactive; known for anxiety, inflammation, and seizure relief
  • CBG (Cannabigerol) — the “mother cannabinoid”; anti-inflammatory and antibacterial properties
  • CBC (Cannabichromene) — supports pain relief and anti-inflammatory effects
  • CBN (Cannabinol) — mildly psychoactive; widely used as a natural sleep aid
  • THCA & CBDA — raw, non-psychoactive acid forms that activate when heated

Why does TAC matter on a label?

A product’s TAC number tells you everything about its cannabinoids. Not just how strong it is. Two products can have the THC number but different TAC numbers. This means they will feel and work differently.The more cannabinoids a product has the better it might work. Research shows that when cannabinoids are combined they can help each other. This is called the entourage effect.When cannabinoids work together they might help more. TAC tells you how much of every cannabinoid is, in a product.

Key insight: Research shows that a diverse cannabinoid profile, reflected in a higher TAC, can enhance therapeutic outcomes through the entourage effect, where cannabinoids amplify each other’s benefits when combined (Russo, 2011, British Journal of Pharmacology).

Key Differences Between TAC and THC

1.Scope: THC refers specifically to one cannabinoid, while TAC encompasses the total concentration of all active cannabinoids in a cannabis strain. This makes TAC a more inclusive measure.

2.Effects: THC is primarily responsible for the psychoactive effects of cannabis. In contrast, TAC includes non-psychoactive cannabinoids like CBD, which can modulate the effects of THC and provide additional therapeutic benefits.

3.Measurement: THC levels are often highlighted on cannabis products to indicate potency. TAC, however, provides a fuller picture of a strain’s chemical makeup, which can be particularly useful for medical cannabis patients seeking specific therapeutic effects.

Why TAC Matters

Understanding TAC is important for several reasons:

1.Holistic Understanding: TAC offers a more comprehensive view of a cannabis strain’s potential effects. For example, a strain with a high TAC but moderate THC might still provide significant therapeutic benefits due to the presence of other cannabinoids.

2.Therapeutic Benefits: Many cannabinoids work synergistically, enhancing each other’s effects in what is known as the entourage effect. By considering TAC, users can better predict the overall therapeutic potential of a cannabis strain.

3.Personalized Use: For medical cannabis users, understanding TAC can help tailor their consumption to their specific needs. Different combinations of cannabinoids can target different conditions, such as pain, inflammation, anxiety, or epilepsy.

Best Weed Strains: Considering TAC and THC

When selecting the best weed strains, it’s crucial to consider both THC and TAC. Here are some top cannabis strains, highlighting their THC and TAC content, to help you make an informed choice:

1.ACDC

  • THC: Very low, usually around 1-2%
  • TAC: High, primarily CBD, making it ideal for pain relief and anxiety without psychoactive effects.

2.Blue Dream

  • THC: Moderate to high, typically around 17-24%
  • TAC: Includes CBG and CBC, providing a balanced, relaxing high with potential anti-inflammatory benefits.

3.Harlequin

  • THC: Low, about 4-7%THC: Low, about 4-7%
  • TAC: High CBD content, excellent for pain and anxiety relief while maintaining a clear head.

4.Northern Lights

  • THC: High, around 16-21%
  • TAC: Includes small amounts of CBN, enhancing its sedative effects, making it great for insomnia and stress.

5.Charlotte’s Web

Practical Applications of TAC and THC Knowledge

1.Medical Use: Patients seeking specific therapeutic effects should look at TAC to understand the full cannabinoid profile of a strain. For instance, those needing pain relief might benefit from strains with a high TAC that includes both THC and CBD.

2.Recreational Use: Recreational users often focus on THC content for its psychoactive effects. However, considering TAC can enhance the overall experience by providing a more balanced and nuanced high.

3.Cultivation: Growers can use TAC and THC data to breed cannabis strains that meet specific market demands, whether for high-THC recreational use or balanced TAC for medical applications.

4.Product Development: Cannabis product manufacturers can formulate products with targeted cannabinoid profiles by considering both THC and TAC, ensuring consistent and predictable effects for consumers.

Understanding the differences between TAC and THC is essential for anyone interested in cannabis, whether for medical or recreational use. While THC is a key player in the psychoactive effects of cannabis, TAC offers a broader perspective on a strain’s overall cannabinoid profile. By considering both THC and TAC, users can make more informed decisions about the cannabis strains they choose, ensuring they get the most out of their cannabis experience. Whether you are seeking the best weed strains for specific therapeutic benefits or a balanced recreational high, knowledge of TAC and THC will guide you towards better choices and more satisfying results.

Frequently Asked Questions​

TAC stands for Total Active Cannabinoids, which includes THC (tetrahydrocannabinol) and other cannabinoids like CBD (cannabidiol). THC specifically refers to tetrahydrocannabinol, the psychoactive component of cannabis responsible for its intoxicating effects.

Understanding TAC helps consumers and researchers gauge the overall potency and effects of cannabis products. It provides a broader view of the cannabinoid profile beyond just THC, which impacts therapeutic benefits, legality, and potential psychoactive effects.

Legal thresholds for THC content often dictate whether a cannabis product is considered hemp (low THC, legal under federal law in many countries) or marijuana (higher THC, subject to stricter regulations). TAC measurements can influence product categorization and legal compliance.

Higher TAC generally indicates a more potent cannabis product, potentially influencing its psychoactive effects and therapeutic benefits. Products with higher THC may produce stronger psychoactive effects, while those with balanced TAC profiles (including CBD) might offer a more balanced experience.

Consumers should review labels for clear TAC and THC percentages to understand potency and potential effects. This information helps in making informed decisions based on personal preferences, desired effects, and legal considerations.
