What is THCa?
Overview: What is THCa?
THCa, short for tetrahydrocannabinolic acid, is one of the many cannabinoids found in the cannabis plant. In recent months, THCa has gained recognition for it’s significant role in the euphoric experience loved by cannabis enthusiasts. Unlike its well-known counterpart Delta 9 THC (tetrahydrocannabinol), THCa is non-psychoactive, meaning it does not produce the euphoric “high” commonly associated with cannabis consumption. However, THCa is the precursor to Delta 9 THC, which is the cannabinoid most responsible for the psychoactive effect of cannabis.
The conversion of non-intoxicating THCa into psychoactive Delta 9 THC, also known as decarboxylation, is the key element of THCa that has generated buzz in the hemp industry. THCa flower refers to cannabis flower with high levels of THCa, that with exposure to heat, converts to Delta 9 THC and produces the common psychoactive effects associated with cannabis.
THC vs THCa: The Differences
In the realm of cannabis, understanding the difference between THC and THCa is crucial for making informed choices about your experience. Under the 2018 Farm Bill Act, legally compliant hemp products must remain below 0.3% Delta 9 THC on a dry weight basis. THCa alone is non-psychoactive and will produce no effect upon consumption. However, upon exposure to heat through processes like smoking or vaping, THCa undergoes decarboxylation, transforming into THC and unlocking its psychoactive potential. Most recent breakthroughs in hemp genetics and growing methods have created a compelling alternative to legal marijunana for states where hemp-derived cannabis is legal.

Delta 9 vs. THCa: The Differences
THCa, or tetrahydrocannabinolic acid, represents the unactivated form of THC. As we previously mentioned, THCa alone lacks the psychoactive effects commonly associated with cannabis, serving as the precursor that, through decarboxylation, undergoes a remarkable conversion into the more potent Delta 9 THC. In other words, THCa plays a significant role in the creation of Delta 9 THC and the associated euphoric effects in both cannabis and marijuana plants.
For those unfamiliar with the marijuana industry in states like Colorado or California, the THCa and cannabis chemistry lingo may seem like a foreign language, it’s daunting. If you were to pick up a label and inspect the contents in these marijuana legal states, total THC measurements would include both THCa and THC as they go hand in hand in complementing the user’s cannabis experience. This same harmonious blend also applies to hemp-derived THC cannabis products, but due to a lack of reliable information surrounding this subject, there has been reluctance from many. We will now dive into the specifics of hemp-derived THCa, how it works, and what are the potential benefits.
How Does THCa Work?
It is crucial to distinguish between hemp-derived and marijuana-derived THCa. Hemp plants contain minimal amounts of Delta 9 THC (<0.3%), ensuring that hemp-derived THCa products comply with legal standards. On the other hand, marijuana-derived THCa may contain higher levels of THC, potentially leading to psychoactive effects.
THCa is typically found in raw or unheated cannabis plants, and it undergoes a process called decarboxylation to convert into Delta 9 THC. When cannabis is exposed to heat, such as through smoking, vaping, or cooking, the carboxyl group in THCa is removed in a process called decarboxylation, which then turns into Delta 9 THC.

Legality of THCa
The legality of THCa hinges on its source. Hemp-derived THCa, with its low THC content, is generally legal in many jurisdictions. As laws surrounding cannabis and hemp continue to evolve, consumers should stay informed about the legal status of THCa in their region.
Thanks to the 2018 Farm Bill, the legal status of hemp and hemp-derived products changed dramatically in the United States. Under this legislation, hemp products with up to 0.3 percent Delta-9 THC (tetrahydrocannabinol) became federally legal. This inclusivity extended to numerous hemp products, including THCa hemp flower and other cannabinoids, making high THCa flower accessible to consumers for the first time. [1]
North Carolina’s legal stance aligns with the 2018 Hemp Farm Bill, which mandates that all Delta 9 THC products contain less than 0.3% THC. This distinction places marijuana (with THC content greater than 0.3%) and hemp-derived products like THCa (with less than 0.3% THC) in different legal categories. At Dogwood, we ensure our hemp flower displays a lower THC content. This allows us to remain within legal guidelines while maintaining high levels of THCa. The beauty lies in the consumption: THCa’s transformation into THC means users can enjoy the desired effects legally.
Potential Benefits of THCa
THCa, despite being non-psychoactive in its raw form, has shown promise in offering various potential therapeutic benefits. Additionally, the conversion of THCa to Delta 9 THC opens the possibility for potential benefits. While research is ongoing and more comprehensive studies are needed, preliminary findings suggest that THCa may have several advantageous properties, particularly in the realm of health and wellness. It is important to realize THCa is not a fix all, and all information is anecdotal, always consult a healthcare professional when considering THCa or any other alternatives as a remedy.
Anti-Inflammatory Properties: THCa has been studied for its potential anti-inflammatory effects. Inflammation is a key factor in many chronic conditions, such as arthritis, inflammatory bowel disease, and neurodegenerative disorders. While more research is needed, there is promising studies in this domain. [2]
Neuroprotective Effects: Some studies indicate that THCa may possess neuroprotective properties, meaning it could help protect nerve cells from damage or degeneration. This aspect is particularly relevant in conditions like Parkinson’s disease, Alzheimer’s disease, and multiple sclerosis, where maintaining neurological health is crucial for quality of life. [3]
Anti-Nausea and Appetite Stimulation: THCa has been explored for its potential antiemetic (anti-nausea) properties. This is of interest in medical contexts, especially for patients undergoing chemotherapy or experiencing nausea and vomiting due to various conditions. Additionally, THCa’s ability to stimulate appetite could be beneficial for individuals with appetite loss or eating disorders.
Pain Management: Preliminary research suggests that THCa may contribute to pain management. Chronic pain conditions, such as neuropathic pain, arthritis, and fibromyalgia, are areas where THCa’s potential analgesic (pain-relieving) effects could be explored further.
Anti-Cancer Potential: While research is in early stages, some studies suggest that THCa may have anti-cancer properties. This includes potential inhibition of cancer cell growth and promotion of apoptosis (cell death) in certain cancer types. However, more research is needed to understand the mechanisms and efficacy of THCa in cancer treatment. [4]
It’s important to note that while these potential benefits are promising, further clinical trials and research are necessary to validate and fully understand THCa’s therapeutic effects. As the scientific understanding of cannabis compounds continues to evolve, THCa remains an area of interest for its potential contributions to health and wellness.
Safety and Side Effects of THCa
When smoking THCa flower, the effects can vary depending on the individual and the specific strain. Common effects may include euphoria, relaxation, increased creativity and deep feelings of relief. It’s important to note that because everyone’s system is unique, the effects may differ depending on the individual [5].
What are the potential adverse effects?
The most common side effects of THCa and cannabis use are anxiety, paranoia, and dry mouth. Some individuals might experience gastrointestinal disturbances, such as nausea or diarrhea, especially if consumed in large quantities. Preliminary studies suggest that THCa might affect the way certain drugs are metabolized, potentially enhancing, or diminishing their effects. It is essential to consult with a healthcare professional before using THCa, especially for those already taking prescription medications.
What is the recommended dosage?
Because everyone’s system is unique, the effects may differ depending on the individual. When smoking THCa flower, the onset time is only a few minutes, so you can determine the right amount for you through gradual inhalation. It is always advised to start with a smaller dose and increase gradually to help the body acclimate and mitigate potential side effects.
What is a high THCa percentage?
A high THCa percentage refers to the concentration of the raw cannabinoid in a cannabis flower or hemp flower product. The ideal THCa percentage depends on individual preferences and desired outcomes. Yet, many people seek potent THCa hemp flower. For high THCa hemp flower, a good THCa percentage typically ranges from 15-30 percent, although strains with even higher concentrations are available.
