THCa vs THC: Which Is Stronger?

Thca Vs Thc Which Is Stronger

As of 2025, THCA accounts for nearly 15% of the total cannabinoid market share - significantly up from less than 2% in 2020.

But what's the difference between up-and-coming THCA and the ever-popular THC? 

Keep reading to find out more.

Key takeaways:

  • THCa on its own does not contain psychoactive properties, unlike THC.
  • THCa and THC are similar in some ways but contain key differences that impact their effects and usage.
  • THCa converts to THC when heated through a process called decarboxylation.
  • Smoking THCA products can produce intoxicating effects due to the heat, but THCA can also be consumed in an edible form.

What is THCa?

Whether you are currently experiencing physical pain or signs of stress, you may be wondering whether the solution could be hidden inside the cannabis plant.

The cannabis plant has been looked to for thousands of years for its wide variety of health benefits.

But when shopping for cannabis products to treat physical and emotional symptoms, how can you be sure which product is best to address your specific needs?

The truth is, compounds like THCa (Tetrahydrocannabinolic acid) and THC (tetrahydrocannabinol), while similar in some ways, are vastly different and impact the body in various ways.

Whether from a medical standpoint or a legal standpoint, it is helpful to fully grasp the differences between the two in order to make an educated decision regarding the best product for you.

Tetrahydrocannabinolic acid, or THCa, is a natural compound that can be found in raw, unheated cannabis plants. It is a non-psychoactive cannabinoid that shares some similarities with THC. But unlike THC, THCa doesn’t produce a “high” in its raw form. 

What is THC?

THC, or tetrahydrocannabinol, is the psychoactive compound naturally found in the cannabis plant. 

It works by interacting with the body's cannabinoid receptors to provide intoxicating effects, including relaxation, euphoria, altered perception, and even increased appetite. 

THCa vs. THC: Key differences

While similar in some ways, there are key differences between THCa and THC.

The most significant difference between THCa and THC can be found in a single carboxyl group. This single carboxyl group is lost when THCA is heated, in a process known as decarboxylation.

When heated, smoked, or vaporized, cannabis undergoes a chemical reaction that sees THCa converted to the psychoactive THC. 

Once THCa undergoes decarboxylation, its chemical structure changes, causing it to adopt psychoactive properties.

THCa vs. THC: Which is stronger?

While THC is not technically “stronger” than THCa, it can cause psychoactive effects that THCa does not unless heated. 

More research is needed to fully understand the impact of THC and THCa and how they can affect certain physical symptoms.

THCa: Potential health benefits

There is currently evidence to suggest that THCa may offer therapeutic benefits when taken in raw form. Some of these benefits may be anti-inflammatory, antiemetic, neuroprotective, and antioxidant. 

Anti-nausea properties

Anti-nausea effects can be particularly helpful for users dealing with certain medical conditions. THCa shows promise in alleviating nausea brought on by chemotherapy and other cancer drugs.

Anti-inflammatory effects

Other potential therapeutic benefits of THCa may include anti-inflammatory effects.

THCa may even help with digestive issues and autoimmune conditions.

THCa also may help in protecting the brain against neurodegenerative diseases, including Alzheimer’s and Parkinson’s.

THC: Potential health benefits

THC is the primary psychoactive compound found in the cannabis plant. Due to its psychoactive effects, THC is commonly consumed for recreational use and even medical use.

There are many well-documented benefits associated with THC use that go beyond psychological aspects. These include:

  • Pain relief
  • Nausea reduction
  • Appetite stimulation (in cases of chemotherapy) 
  • Muscle relaxation
  • Stress relief
  • Anxiety relief

Pain relief

THC can provide moderate pain relief due to its interaction with the body’s endocannabinoid system. These effects can be particularly beneficial for neuropathic conditions and in the management of chronic pain.

Nausea reduction

THC interacts with the endocannabinoid receptors in the brain and gut, also known as the brain-gut axis, which is responsible for regulating digestive functions. This can even suppress the urge to vomit, making THC helpful in battling nausea. 

Appetite stimulation

THC stimulates the appetite by interacting with the body’s CB1 receptors, triggering effects like increased hunger, often referred to as “the munchies.” 

On a deeper level, THC stimulates neurons in the brain’s hypothalamus, which is the portion of the brain responsible for food cravings. This can cause hunger even though your body is not in need of calories. 

These effects are why THCa, THC, and other cannabis products are used for patients dealing with certain conditions that affect appetite.

Muscle relaxation

THC has the potential to act as a muscle relaxant. It achieves this effect by interacting with the body’s endocannabinoid system to reduce muscle spasms and improve motility. 

THC may even help with spasm control in individuals with neurological conditions like Multiple Sclerosis (MS).

How do THC and THCa impact mental health?

People dealing with mental health challenges may find that cannabis use helps alleviate symptoms associated with stress and anxiety.

THC interacts with the body’s CB1 receptors, which can impact mood and relaxation. Due to this, THC in lower doses can provide relief from anxiety, while higher doses may have the opposite effect and instead cause panic or anxiety. 

As of now, there are no cannabis-derived products that have been approved by the FDA to treat mental health issues, though anecdotal evidence is promising. 

Cannabis’s psychoactive effects can vary from person to person. Because of this, individuals dealing with stress or anxiety should start with a very low dose of these products in order to first gauge their reaction. 

Choosing the right cannabis product

The right cannabis product for an individual may vary from person to person. Whether THCa or THC is the better choice for you will depend on the underlying reason for use and preferred consumption methods.

For example, some cannabis users may use THC products for their psychoactive effects, while others may use them solely for potential medical benefits. 

Clean Remedies is one retailer offering a wide range of THC and CBD products to help address various health concerns, from stress and anxiety to pain relief. 

Different THCa and THC consumption methods

There are various ways to consume cannabis to reap the benefits of THCa and THC.

Different smoking methods can affect how quickly THC’s effects kick in, their intensity, and how long these effects can last. 

Some of today's most popular consumption methods for smoking THC and THCa products include:

Smoking, vaping, and dabbing

Factors like concentration, temperature, and absorption rate can all affect how strong THCA and THC are to an individual. 

Smoking, vaping, and dabbing cannabis flower remains a popular way to indulge in cannabis. Each of these methods can impact the psychoactive effects of THC.

By smoking cannabis flower, effects occur almost immediately, often within minutes. The duration of these effects can last anywhere from 2 to 4 hours. Vaping cannabis can have similar effects, while dabbing THC extracts can produce effects in seconds. 

Edibles and beverages

Popular edibles include THC or CBD gummies, brownies, chocolates with THC, or beverages. When consumed, THC’s effects can occur in as little as 30 minutes to two hours.

The reason for the longer onset is that THC must be digested and metabolized by the liver in order to take effect. Because of this, the effects can last even longer than other methods of consumption — from 4 to 8 hours or sometimes longer. 

Many individuals turn to edibles due to convenience, flavor, and enjoyment. There's no need to smoke or vape anything, and your taste buds will thank you, too!

Sublingual tinctures

Many cannabis users consume THC in tincture form. When taken sublingually (under the tongue), THC is absorbed directly into the bloodstream. This means effects can come in as little as 15-45 minutes, making the onset quicker than edibles. 

When taking THC in tincture form, effects can last anywhere between 4 and 6 hours. When swallowed or mixed with food (which is recommended), effects can last for as long as 8 hours. During this time, users may experience a sense of calm and relaxation. Another benefit of THC tinctures is improved sleep quality. 

THCa, on the other hand, can be made by juicing raw cannabis leaves or flower or by making capsules that preserve the raw cannabinoid. 

Raw cannabis

One of the most common ways to enjoy the benefits of THCa is through consuming fresh cannabis in smoothies or juices. This allows the body to absorb it without converting it into THC, as would happen through smoking.

Another way to consume THCa is through specially made products such as capsules, crystalline “diamonds”, or other tinctures. All of these are specially manufactured to isolate THCa.

Are THC and THCa legal?

The legalities surrounding THCa products like THCA flower and delta-9 THC depend largely on where you live and whether recreational cannabis is legal in that particular state.

THCa in its raw, unheated form is legal under certain conditions, although the laws are constantly evolving. Just be sure to check your local laws and regulations before buying or consuming THC or THCA products.

Current cannabis legislation

Currently, due to legislation under the 2018 Farm Bill, hemp and its hemp gummies are legal so long as they don’t contain more than 0.3% delta-9 THC by dry weight. 

Do THCa and THC show up on a drug test?

Both THC and THCa can result in a positive drug test. Although most drug tests are focused on THC and its metabolites, THCA can be converted into THC and then broken down into THC metabolites, which can trigger a positive result in today’s standard THC drug tests. 

Conclusion

Finding the right type of THCa and THC products for your unique needs is important if you are hoping to reap the full benefits the cannabis plant has to offer.

THCa and THC products continue to provide much-needed relief for users dealing with a broad spectrum of physical and psychological symptoms. Whether for medical or recreational use, there is no disputing the popularity of THC, THCa, and other delta-9 THC products.

Whether consumed orally or topically, the benefits of these compounds can have a profound impact on quality of life.
