THCa (tetrahydrocannabinolic acid) is a naturally occurring cannabinoid found abundantly in raw cannabis buds, and it lacks psychoactive properties in its unprocessed state. However, when THCa is heated, smoked, or vaped, it converts into psychoactive THC, which can pose more significant risks.

This transformed substance can lead to altered sensations, impaired physical coordination, and, at higher doses, hallucinations. While possession of THCa is legal in most U.S. states, unregulated products sold online can be risky due to potential contamination and unknown potency levels. If someone you know is struggling with THCa or THC use and it’s affecting their health and well-being, Hanley can offer solutions and support to help them on the path to recovery.

What Is THCa?

THCa stands for tetrahydrocannabinolic acid, a non-intoxicating compound found in cannabis. It serves as the precursor to delta-9-tetrahydrocannabinol (THC), the widely recognized hallucinogenic compound in cannabis. In its natural state, cannabis plants produce THCa instead of THC. The levels of THCa are typically higher in fresh, uncured cannabis plants compared to dried ones.

What Happens When THCa Is Heated or Smoked?

When cannabis is heated or decarboxylated through methods like smoking, vaping, or cooking, THCa undergoes a chemical transformation, converting into THC. This conversion occurs by removing a carboxyl group (COOH) from THCa, leading to the creation of THC. Once THC is formed, it is inhaled or smoked, rapidly entering the bloodstream through the lungs. From there, it travels to the brain and various parts of the body, binding primarily to cannabinoid receptors like CB1 receptors, which triggers a range of effects. These effects can vary from person to person and are influenced by factors such as dosage, individual sensitivity, and the potency of the cannabis strain used.

Is THCa Legal to Use?

At the federal level, THCa is permissible as long as it meets the acceptable threshold of 0.3% delta-9 THC. However, individual state regulations can vary regarding this cannabinoid. Due to differing interpretations of hemp laws, THCa products may be more accessible than THC products in certain jurisdictions, creating a potential legal workaround for those seeking cannabis’s euphoric effects. In Florida, only delta-9 THC is prohibited under the state’s medicinal marijuana laws, so there are currently no restrictions on consuming THCa derived from hemp. Texas adheres to the federal cannabis policy, making Farm Bill-compliant THCa legal there.

Differences Between THCA and Cannabigerol


THCa is the precursor to THC (tetrahydrocannabinol), the primary psychoactive compound in cannabis. THCa is found in raw cannabis buds and does not have psychoactive effects until it is heated or decarboxylated, converting into THC.


Cannabigerol is considered a minor cannabinoid and is also found in raw cannabis. It is the precursor to other cannabinoids like THC, CBD (cannabidiol), and CBC (cannabichromene). CBG is present in lower concentrations compared to THC and CBD in most cannabis strains.

Alternative to THCA

Psychoactive Alternative:

If you’re specifically interested in the psychoactive effects of THC but want an alternative to THCa, you could consider THC (tetrahydrocannabinol) itself. Unlike THCa, THC is psychoactive and produces the “high” associated with cannabis when consumed. However, it’s essential to note that THC’s legality and availability vary depending on local regulations.

THCa Side Effects

THCa, when consumed in its raw form, does not typically induce intoxication or psychoactive effects. Ingesting raw THCa or THCa-infused gummies will not result in a “high,” although it can register on a drug test and potentially lead to a failed test. However, consuming THCa without the psychoactive effects of THC can still lead to less desirable side effects, including nausea, indigestion, allergic reactions like skin rashes or respiratory symptoms, and potential drug interactions with medications.

The main concern with THCa arises when its properties are altered through processes like cooking, heating, or vaping, which can transform it into the psychoactive THC compound.

Short-Term Effects of Heating/Smoking THCa:

  • Euphoria and relaxation
  • Changes in perception
  • Impaired memory and cognition
  • Dry mouth and increased thirst
  • Bloodshot eyes
  • Elevated heart rate
  • Anxiety and paranoia

Long-Term Effects of Smoking THCa:

  • Regular and excessive THC use, particularly starting in the teenage years, can lead to adverse outcomes, including potential addiction with withdrawal symptoms upon cessation.
  • Smoking THC, similar to smoking any substance, can have significant impacts on lung health, potentially causing respiratory issues and chronic bronchitis.
  • While the connection between THC and mental health is complex, prolonged or excessive use of high-potency THC has been associated with an increased risk of mental health disorders such as depression, anxiety, and psychosis.

Dangers of Unregulated THCa

Regulated THCa supplements may be offered as raw food supplements in capsule form. In such instances, a product can be verified as strictly THCa through analysis conducted by an accredited third-party laboratory, with the results compiled in a comprehensive report. On the other hand, unregulated THCa products sourced from various sources pose several risks to users. These unregulated products are often sold online and may contain undisclosed substances or impurities, making them potentially unsafe for consumption.

Six Risks of Unregulated THCa

  1. Inconsistent Potency: Unregulated THCa products may lack standardized testing for potency and quality control, leading to variations in THCa concentration. This inconsistency makes it challenging to determine the appropriate dosage, potentially leading to unexpected effects.
  2. Contamination: Uncontrolled THCa products pose a higher risk of contamination due to the absence of regulatory oversight. Contaminants such as pesticides, heavy metals, molds, and other harmful substances could be present, posing health risks upon consumption.
  3. Lack of Labeling and Information: Unregulated products often lack accurate labeling and comprehensive information regarding dosage, potency, ingredients, and potential side effects. This lack of transparency makes it difficult for consumers to make informed decisions about their purchases.
  4. Legal Implications: Unregulated THCa products may be illegal in certain jurisdictions, leading to potential legal consequences such as fines or criminal charges for purchasing or possessing them.
  5. Safety Concerns: The absence of quality control measures in manufacturing unregulated products raises concerns about unsafe production practices, improper handling, and subpar product quality, posing safety risks to consumers.
  6. Lack of Consumer Protection: Unregulated products do not offer the same level of consumer protection as regulated markets. Consumers may have difficulty reporting adverse reactions, seeking compensation for losses, or ensuring product recalls in case of safety issues.


THCa, a naturally occurring cannabinoid in raw cannabis, lacks psychoactive effects in its unprocessed state. However, when heated or vaped, it transforms into THC, which can lead to altered sensations and potential health risks. While THCa possession is legal in many states, caution is needed with unregulated products due to contamination and uncertain potency levels. If someone is facing challenges related to THCa or THC use, seeking professional support and guidance, such as that offered by Hanley, can be crucial for their well-being and recovery journey.
