What is THCa flower?

THCa (tetrahydrocannabinolic acid) flower applies to any and all strains of hemp flower that have high levels of THCa in them. As long as the Delta 9 THC level is .3% or lower then it’s classified as hemp (according to the 2018 Hemp Farming Act) and can be legally sold online under federal law.

THC vs THCa

THC and THCa are two of over 100 different cannabinoids that can be found in the cannabis plant.

THC is the primary psychoactive compound and is responsible for the "high" associated with cannabis use.

THCa is not psychoactive and is found in the raw, unheated plant material. However, when THCa is exposed to heat, it is decarboxylated and converted to THC.

Will THCa flower get you high?

THCa is not a psychoactive compound, so when THCa hemp flower is consumed in its raw, unheated state, it is unable to make its user feel high. However, when THCa is decarboxylated, via smoking or vaping, it is converted to THC, enabling it to bind to cannabinoid receptors in the brain and produce intoxicating effects.

What is decarboxylation?

Decarboxylation is a chemical process that removes a carboxyl group from a molecule, resulting in the release of carbon dioxide.

In the context of cannabis, decarboxylation is the process of heating the plant material to activate cannabinoids like THC and CBD.

In raw cannabis, cannabinoids exist in their acidic form, such as THCa (tetrahydrocannabinolic acid), CBDa (cannabidiolic acid), CBGa, CBCa, and so on.

Decarboxylation occurs naturally over time as the cannabis plant dries and ages, but it can also be accelerated by heating the plant material.

The most common at-home method of decarboxylation involves baking or heating the cannabis in an oven. Additionally, decarboxylation can also occur when smoking or vaporizing cannabis, as the heat from the flame or vaporizer activates the cannabinoids.

It’s estimated that THCa converts into THC at a rate of around 87.7%

THC vs THCa flower - cannabis labeling

In order to better understand the difference between THC and THCa flower, let’s take a quick look at two images. The first one is a picture of a cannabis flower label and the second one shows a hemp flower lab report.

First up, this label for a strain called Dutch Treat shows a THC content of 0.80% (in blue). This identifies the flower as a cannabis strain as this is over the legal threshold of 0.3% for hemp.

The THCa content is shown in red and then the total THC level (in green) actually indicates how much THC you might end up with after the THCa has been decarboxylated. Therefore, this “total THC” content is, more specifically, a “total potential THC” content that includes both the THCa and THC.

Next up, on this high THCa flower lab report, you can see that the Delta 9 THC level (in red) is just 0.267%. So, in the eyes of the law, this is a hemp flower strain.

However, this strain also contains 21.657% THCa (in purple), making a total potential THC level of 19.26%. This means that this hemp flower strain will also have incredibly intoxicating effects if it’s smoked or vaped (anything upwards of 15% total THC is considered to be highly potent), despite it being classified as hemp.

Is THCa flower legal in the US?

The legality of THCa flower in the US all depends on the Delta 9 THC content of the flower. Hemp is defined as cannabis with a THC content of 0.3% or less by dry weight, so as long as the THCa flower you buy is legally classified as hemp flower, then it is federally legal according to the 2018 Farm Bill.

However, some state and local laws may vary, and some states may have stricter regulations regarding hemp and hemp-derived products.

Is THCa legal in Texas?

Yes, THCa and THCa flower is legal in Texas as long as the THC level is compliant with the federal limits for hemp. According to Texas.gov, “Consumable hemp products with less than 0.3% Delta-9 tetrahydrocannabinol THC are permitted under Chapter 443 of the Texas Health & Safety Code.”

THCa flower - benefits and uses

Due to the fact that THCa transforms into THC when it’s heated, THCa flower can offer different uses, depending on whether it’s ingested raw or heated first.

  • Raw THCa flower

In its raw state, THCa flower may offer unique therapeutic benefits due to its non-psychoactive nature and potential anti-inflammatory and neuroprotective properties.

You can learn more about the potential benefits of THCa here.

Raw THCa flower can be consumed by juicing the raw plant material or using it in food preparations such as smoothies and salads. Juicing is particularly popular, as it allows for the consumption of large quantities of THCa without the psychoactive effects of THC. Some people also use THCa flower as a topical treatment for skin conditions such as eczema and psoriasis.

  • Heated THCa flower

If THCa is decarboxylated, through heating, smoking, or vaping it’s estimated that almost 90% of the THCa within the flower transforms into THC. So, despite hemp only having .3% or less THC, the many therapeutic benefits of THC can be accessed by smoking or vaping THCa flower.

Delta-9-tetrahydrocannabinol (THC) is a psychoactive compound that has been studied extensively for its potential therapeutic benefits. THC can activate the endocannabinoid system in the brain and body, which plays a critical role in regulating mood, pain, appetite, as well as many other physiological and cognitive processes.

THC LAWS IN TEXAS (FAQ’s)

Still not sure where you stand on THC vs THCa in the eyes of the law? Here’s a quick Q&A session to answer any remaining questions you have about the legality of THC and THCa in Texas:

Is THC legal in Texas?

These days, there are many different types of THC available on the market, including Delta 8, Delta 9, and Delta 10 THC, so it really depends on what type of THC you’re talking about!

Is Delta 9 THC legal in Texas?

No, Delta 9 THC is a controlled substance (it’s in penalty group 2 for the purposes of criminal penalties). However, hemp-derived THC products that contain 0.3% or less Delta 9 THC, by dry weight, are legal.

So, as long as you buy your hemp-derived THC products from a reputable vendor, you can be sure that the amount of THC offered (within their products) is legally compliant with both federal and state laws.

Is Delta 8 THC legal in Texas?

Yes, like Delta 10 THC, Delta 8 THC is legal in the state of Texas because it is a hemp-derived cannabinoid and neither Delta 8 or 10 are named substances in the Controlled Substances Act (only Delta 9 THC is).

Are THC vapes legal in Texas?

THC vapes may or may not be legal, depending on whether they contain Delta 8 or Delta 9 THC (see above). The best THC carts in Texas (that you can buy legally) are Delta 8 THC vapes (for milder effects) or THCa vape carts (for a more potent experience).
