What Is THCA, and Is It Addictive? The Science Behind This Cannabinoid

The cannabinoid compound THCa found in raw cannabis has become increasingly popular recently among those who challenge the idea that all compounds found in cannabis plants are psychoactive. Yet, one of the most common misconceptions among people who discuss marijuana use is that THCa is a natural, non-psychoactive cannabinoid compound. THCa does actually convert into psychoactive THC in certain usage scenarios. As a result, it can have similar adverse side effects and potentially cause addiction.

For addicts seeking to end their addiction to drugs, removing marijuana and its byproducts from their lives is critical. This guide covers important details about this topic and the many options available for you or a loved one to live a better life without addiction.

What is THCa?

Cannabis plants contain several compounds with unique properties. Some parts of the plants contain more of one specific compound than another. Tetrahydrocannabinolic Acid (THCa or THC-A), found in the greatest concentration in raw buds or underdeveloped flowers, doesn’t act as a psychoactive compound when consumed in raw cannabis. Yet when someone heats a cannabis plant in any way, a decarboxylation organic reaction, or decarb process, breaks down THCa’s carboxylic acid group and removes the carboxyl from the molecule. This action converts THCa into tetrahydrocannabinol (THC or Delta-9 THC), which is psychoactive and the source of the “high” people experience from marijuana and many of its byproducts.

THCa is incredibly similar to THC chemically, but THC doesn’t have the carboxylic acid group. As a result, people who open-burn, cook (i.e., edibles, gummies) and smoke, dabbing or vape the raw cannabis create psychoactive byproducts. It’s important to keep in mind that both THCa and THC differ from Cannabidiol (CBD), another chemical found in marijuana that doesn’t have psychoactive properties. Although some people might experience side effects, they don’t experience the high.

How THCa Affects the Body

As noted by Harvard Health Publishing, the human body contains a widespread endocannabinoid system (ECS) made of cellular receptors and chemical signals that regulate many critical physical functions. The human brain contains more ECS cannabinoid (CB1) receptors than other types. CB1 receptors control most of the activity of other types of neurotransmitters throughout the body that impact everything from a person’s alertness and mood to their hunger and physical temperature.

Endocannabinoid molecules have a similar structure to cannabis plant molecules and provide receptor stimulation, which is how THCa and THC affect human brains. These compounds take over the ECS when introduced to the body. THCa doesn’t bind to CB1 or other brain receptors in the brain’s “reward” system like THC that causes the classic high sensation experienced by casual marijuana users and addicts.

People who choose to consume raw cannabis in juice, salads, smoothies and tinctures often receive many of the health benefits of using the plant without the high. A THCa patch also exists that helps people receive the benefits without dealing with the raw plant at all.

THCa has been found to provide antiemetic, anti-inflammatory, antioxidant, antiseizure, neuroprotective and many other therapeutic benefits. The federal government considers it legal as long as the plant or any product containing it has less than 0.3% Delta-9 THC. State laws vary.

Many people who experience extreme inflammation (i.e., hot swelling, pain and redness) from chronic conditions and environmental factors like environmental hazards and pollution, poor diet and stress might experience a reduction in symptoms because of consuming raw cannabis that contains the unbroken THCa compound. Uncooked marijuana and THCa products might also help people with certain mental health and mood disorders to find balance and experience more uplifted feelings.

Is THCa Addictive?

Although THCa isn’t usually thought of as addictive, it can cause allergic reactions, side effects and prescription and OTC drug interactions in some people that mimic a THC high that causes habit formation and psychological dependence. Some people are naturally ultrasensitive to THCa as well.

The most common reactions and side effects include itching and rashes, gastrointestinal pain and nausea, and respiratory symptoms. Yet, no matter the level of sensitivity, THCa can change a person’s appetite or cause them to feel drowsy or thirsty with dry mouth, as seen with THC.

These issues are especially true if the raw cannabis isn’t cleaned properly and contains harmful or toxic substances like heavy metals, molds and pesticides when consumed, or if a person uses the plant and one or more CBD products at the same time for medical or recreational reasons. That said, for the most part, the addiction only comes from the THC forms after heating the cannabis in any way, including the crystalline form known as “diamonds” that some users add to marijuana before smoking and vaping and when a person consumes a less fresh dry plant that was exposed to hot sunlight too long.

People from any walk of life might accidentally become exposed to THC when they think they’re only using THCa. What are other signs of dependence and cannabis use disorder?

• Altered perception and sensations
• Anxiety or paranoia
• Bloodshot eyes
• Cognition and memory problems
• Craving marijuana
• Euphoria
• Feeling of relaxation
• Hallucinations
• High heart rate
• Reduced physical mobility

These symptoms can continue long after a person discontinues the use of marijuana and any of its byproducts, especially THC. Cannabis use can cause permanent brain damage and serious mental health issues. Inhaling it via smoking or vaping can cause permanent lung damage and lifelong respiratory problems.

Risks of THCa Use

Beyond allergic reactions, side effects and potential THC conversion, casual users of THCa and addicts must understand that THCa usage comes with a lot of risks. Consider the following:

Quality Control

A lack of regulations and standardized testing exists, which means that it’s impossible to prevent quality control issues. Raw marijuana or THCa products might accidentally contain too much THC or some other chemical that can cause dosage problems and unexpected adverse outcomes. A lack of regulations means that consumers shouldn’t trust claims made by anyone selling THCa products. They also have limited methods for seeking justice and no protections if they have an adverse safety event.

Legal and Work Consequences

Diagnostic tests might reveal THCa or THC in the bloodstream. The level of accidental use of THC might be beyond the legal limit, which might place a person at risk of not being believed by police about their marijuana usage if they’re arrested for a crime. They might receive charges for their cannabis usage. Additionally, an employer might not hire a job seeker or might fire an existing employee based on their blood test results.

Gateway to Harder Drugs

Marijuana is often described as a “gateway” or “introductory” drug because people use it thinking it’s harmless and then become so dependent that they chase harder drugs in pursuit of a greater or longer-lasting high. Hard drugs include benzodiazepines or benzos, cocaine, methamphetamine and opioids.

Psychological Impact

Some people’s brain chemistry changes so much after any marijuana usage that they can’t function normally without repeated activation of the reward system. Outside of the previously mentioned side effects, they might suffer lasting anxiety, depression, sudden mood swings and even aggressive and violent behaviors, especially if they’re mixing usage with alcohol or other drugs.

Withdrawal Symptoms

Many people who try to stop their dependence on THCa and THC don’t seek medical help. When they fail to taper off or have someone to support them through detox and withdrawal, they can experience harmful symptoms that peak within 24 to 48 hours after use and can last for weeks or years. Potential symptoms include:

• Abdominal pain
• Anxiety, anger, irritability or aggression
• Decreased appetite
• Depression and negative feelings
• Headaches
• Nausea and vomiting
• Nervousness and shaking
• Restlessness
• Sleep disturbances like insomnia and nightmares
• Severe weight loss

Some people give up their attempts and return to their addiction. The number and intensity of symptoms vary based on different factors, including a person’s genetics, personality and response to stress, the presence of preexisting mental health problems, other habits (i.e., alcohol, tobacco and other drug use) and environmental factors. If the person has a serious underlying condition, these symptoms could potentially even lead to their death.
