Regardless if you are familiar with cannabis or not you probably have some knowledge about THC. But have you heard of THCA?

By definition, Tetrahydrocannabinol (THC) is the chemical compound responsible for the intoxicating effects caused by cannabis use and is most abundantly found in cannabis plants.

But what the heck is THCA, where does it come from and how can it be used?

Believe it or not – if you were to chew on the leaves of some freshly picked high-THC cannabis leaves or flowers, it won’t make you feel anything effects. Why? Maybe to your surprise, there is almost no THC present in raw cannabis plant material. Again, we ask ‘why’? To properly answer these questions we have composed a THCA vs THC guide.

What is THCA?

THCA (Tetrahydrocannabinol Acid) is the non-psychoactive precursor to THC. When heated, THC A decarboxylates and turns into THC. In other words, all THC was once THCA. You will most likely find higher levels of THCA in fresh flowers and from the living plant itself.

THCA vs THC – What Is The Difference?

THC A is different from THC in both its chemical makeup and how it interacts with the human body. THCA physically becomes THC during the heating process, such as when smoking, vaping, or cooking for a while before ingesting.

Heat and light lead to a chemical reaction called decarboxylation, which results in a molecule that more readily interacts with the body. THCA molecules are larger than THC molecules and do not bind to the body’s cannabinoid receptors that make up the endocannabinoid system.

Because of the above stated, it doesn’t mean there are no benefits to THCA or raw cannabis. Let’s review some of the health benefits of THCA below in more detail.

What Are The Health Benefits of THCA?

Although it is true that more studies are needed to confirm all the benefits of THCA before we can fully understand it, we may concede that it has already shown to have some of the following positive effects on the human body.

As a matter of fact, some preliminary research and anecdotal evidence suggest that THCA will play a great role in cannabis medicine as the industry moves forward.

Reported benefits include the following;

  • Anti-inflammatory properties for the effective treatment of  lupus disease and arthritis
  • Anti-anxiety properties fro the treatment of stress and anxiety
  • Ant-emetic properties for treatment of appetite loss and nausea
  • Neuroprotective properties for the treatment of neurodegenerative diseases
  • Anti-proliferative properties have been noted in studies of prostate cancer
  • Other medicinal benefits reported by patients include relief from pain, muscle spasms and insomnia.

How to Consume and How to Dab THC A

The best way to smoke THCA is to dab or vape THCA crystalline. The dabbing process simply requires specific equipment, including a dab rig – ensuring you get the most efficient use out of your THCA crystals.

Although you can probably smoke THCA products in your bong with some tweaking, a dab rig is a much better option.

In addition to using a dab rig to dab THC A, you can also use a vape box or box mod vaporizer. Working similar to traditional vaporizers, the coil inside is heated by a battery. Once you heat the coil, the vapor will start to build, and then you’re ready to inhale it.

To do this, add your THCA crystals to the special loading compartment on your box, activate the temperature control, and be enlightened.

Since there is almost 100% THC in THCA, it makes it easy for you to measure how much you consume.

How to Make THCA Isolate and/or Crystalline

The process of creating THCA crystalline and live resin is quite complicated in terms of chemistry, but it’s not rocket science to execute if you’re really interested in the process. First, your high-quality product should be treated with methanol, and then pexane. Doing this will ensure the separation of the dissolved plant matter from acidic cannabinoids.

After an hour or so, the mixture will settle and must then be filtered. The acetic acid and hexane are evaporated off – where the resulting concentrate is mostly THCA. 

After this step, chromatography methods are used to purify the concentrate even further. Once the chromatography process is finished, it’s time for chemical washes, a filter, and a round of roto-vapes.

Finally, after one last round of roto-vape, your result is THCA diamonds with greater than 99.97% of pure THC content. Now that the point of purity diamonds has been reached, how do you end up with both live resin and THCA crystals? Please note this technique takes a while, and so patients is key when making live resin.

The best way to achieve the above said, is to create butane hash oil (BHO), and then purge it at about 90 degrees Fahrenheit. Doing the above will evaporate most of the butane. Once that's done, be sure to seal the concentrate in a container for three weeks. 

During the three weeks, the THCA will naturally crystallize at the bottom of the container. What you are left with is the live resin.

After the crystals form, it’s time to separate them from the live resin. It should be a manageable task, as the live resin will pour off by itself. Ideally, live resin and crystals are purged at different times, after which, both the crystals and the live resin are now ready to use.

You can either recombine them for a flavorful concentrate, or use them separately for various other products.

Will THCA Make You Fail a Drug Test? Is It Legal?

Tetrahydrocannabinol acid (THCA) is not a banned substance as of yet. With that said, currently, THCA could likely be considered an equivalent of THC and possession of it could therefore be prosecuted under the Federal Analogue Act.

With that being said, no sample of THCA is completely free of THC. THCA can be found in blood and urine samples. And where standard hair tests will not detect THCA, forensic hair analysis is capable of measuring THCA in hair samples.

THC A Product Selection

Living THCA tincture is made with fresh-frozen cannabis and MCT oil. Raw THCA tincture promotes overall wellness with a full spectrum of cannabinoids and a full terpene profile. THCA Acid tinctures are non-psychoactive and has a very high terpene and antioxidant content.

THCA has its own unique properties that are quite different from the more commonly known THC properties. THCA has been found to have powerful analgesic (pain reliever), anti-inflammatory, antispasmodic and  neuroprotectant, properties. THCA tincture made with specially formulated full-plant extract combined with MCT oil is most recommended. ‘

As a note of interest, MCT oil has nutritional benefits, it is rapidly absorbed by the bloodstream and is easy to digest – so it makes for a good blending source.

Blending MCT with extract also produces a very even THCA tincture thanks to the compatible molecule size. THCA Tincture is highly recommended and all the more praised for its health benefits.

A Definition of THCA Sand

If you’ve never heard of live resin beach sand before, you’re not the only one. THCA sand is live resin beach sand on steroids, might we say. More precisely, THCA sand is a more concentrated product (95%+ purity) referred to as sand, due to its fine crystalline texture.

This pivotal part of the process takes place when heat is applied, for example upon combustion. When the crystalline concentrate is then finally derived from the live resin, it is then referred to as live resin beach sand.

What is DTHC Weed?

DTHC weed is the amount of activated THC present in fresh flowers, meaning no chemical reaction is necessary for the psychoactive effects of THC to take place.

This number is usually <0.00%, which is why you can't get high from simply ingesting bud. It has to be properly dried and cured, for starters.

THCA Diamonds & How To Make Them

THCA diamonds are made by carefully separating and crystallizing THCA molecules from the rest of the cannabis extract. The process starts by separating out the oil, waxes, and other unwanted compounds from the trichomes harvested from high-THC marijuana plants.

The THC then needs to be decarboxylated before it can become crystalline. After this is done, a solution is prepared with a solvent like tetrahydrofuran (THF) or ethanol that helps dissolve other compounds so that only pure THCA remains.

Then, cooling or heating may be used to induce THC crystal formation within the solution.

Once crystals form and settle in a single layer on the bottom of a container or dish, they are collected and dried to create THCA diamonds! Amazingly pure thca diamonds!

How To Smoke Diamonds

To smoke THCA diamonds, you will need a dab rig or an oil rig. After heating up the nail or banger on your device, use a dab tool to place the THCA diamond onto it.

Inhale through the mouthpiece and enjoy! Be sure to regulate your temperature and keep it low for optimal flavor. You can also mix in some terpenes for added flavor when smoking.

THC A vs THC  Wrap-up

However way you choose to consume your cannabis – smoke, eat, vape or juiced – understanding its powerful properties and how and why they interact with your body the way they do is essential in gaining the desired effects and avoiding possible adverse side effects.

Cannabis molecules each have their own benefits and as raw cannabis is further studied; we can rest easy knowing that it’s safe to integrate it into a healthy diet and accompanying lifestyle.

When it comes to THCA vs THC, there is no definitive winner – they are equally intriguing and enticing, in our books. And the best is yet to come…

Research and testing are becoming more readily available to the interested public, with THCA-focused products hitting store shelves in all of their glory and masses.

As we learn more about the benefits of THCA, we can only anticipate further revelations and potential celebrations in the blooming (medicinal) cannabis industry.


What is THC?

Tetrahydrocannabinol, or THC, is the main chemical in weed that makes you feel high. It causes the happy, “high” feeling or being drunk that most people associate with weed use.

What is THC A?

Tetrahydrocannabinolic acid, or THC A, is the building block of THC and is found in cannabis plants that have not been burned. It doesn't get you high and doesn't have the same psychoactive impacts as THC.

How does THC affect the body?

THC affects the endocannabinoid system in the body by attaching to cannabis receptors in the brain and the central nervous system. This relationship causes many physiological effects, such as euphoria, relaxation, changes in how we experience time and space, an increased appetite, and maybe even pain and inflammation relief.

What are the potential medical benefits of THC?

THC has been shown to possibly help with a number of medical problems, such as chronic pain, nausea and vomiting, muscle spasms, sleeplessness, and making you hungry. It is often found in medical cannabis products that help people feel better and ease their symptoms.

Can THCA cause a high?

When you buy THCa in its raw form, it has chemicals that might not work and are very unlikely to get you high. Intoxicating effects of THCa can only happen when it is heated. This process, called decarboxylation, changes THCa into Delta-9 THC, a very strong form of THC.

What does THCA do?

Tetrahydrocannabinolic acid, or THCa, is a naturally occurring cannabinoid that is found in large amounts in raw cannabis buds. When eaten in its raw form, THCa does not make you feel high. When THCa is burned, smoked, or vaped, it changes into the psychoactive THC chemical.

How powerful is THCA?

As a result of not being active and not making people high, THCa is thought to be less powerful than THC. It changes into a stronger THC compound when cooked, though. Crystals and extracts of THCa are sold by some companies. Crystals of this kind can turn into THC when cooked, which has strong effects.

Does THCA test positive?

Although THCa products that have not been heated are still non-psychoactive, eating them will not make you feel high. However, if you smoke, vape, or cook the THCa cannabis, it changes into THC, which means you will test positive for marijuana.

Is THCA federally legal in the United States?

Current legislation considers hemp products to be lawful under both federal and state law as long as they contain no more than 0.3% delta-9 THC in the state and are not food products that have been infused with THC.

Is delta-9 stronger than THCA?

There are no distinctions between delta 9 THC and decarboxylated THCA when compared. When heated, THCA transforms into delta 9 THC, which is the identical chemical with the same potencies and effects.

Is delta-8 stronger than THCA?

You won't ever feel stoned or disoriented from THCa because it doesn't have any psychoactive effects. The psychotropic effects of THCa manifest themselves when the drug becomes heated. In comparison to Delta-8 THC, THCa potency is essentially negligible. Compared to Delta-9 THC, Delta-8 is 40% less potent.

How do I activate my THCA?

To prepare edibles, place your THCa buds on a cookie tray in the oven and heat them for about 30 to 40 minutes at 220°F. The THCA buds must be heated for a longer amount of time and at a lower temperature if you intend to use them for smoking or vaping. Terpenes and cannabinoids are preserved in this way.

Is THCA natural or synthetic?

THCa is a naturally occurring cannabinoid.

Is THCA a controlled substance?

Because it isn't classified as a controlled substance, the cannabinoid THCA is compliant with the Farm Bill. As long as the finished product has no more than 0.3% delta-9 THC on a dry weight basis, the 2018 Farm Bill authorized hemp and its derivatives, including THCA.

Does THCA turn into delta-9?

The psychoactive form of THC found in cannabis plants is called delta-9 THC, which is derived from THCA. Heat treatment transforms thca into delta-9 THC, which is intoxicating in and of itself.

Is THCA legal in Florida?

In Florida as well as the United States, THC-A is permitted by federal law! Florida has explicitly approved all hemp products with a permissible amount of delta 9-THC, in accordance with state legislation that is consistent with federal law.
