Understanding THC: What Is THC and Its Effects

THC, or tetrahydrocannabinol, is the main psychoactive compound in cannabis that causes the ‘high’ sensation. If you are new to THC or have a specific question about it, here is everything you need to know about this helpful plant-based compound. Starting with: what is THC, and how does it work in the body?

What Is THC?

Tetrahydrocannabinol (THC) is the primary psychoactive compound produced by the Cannabis Sativa plant species, which means it is the cornerstone of cannabis’s effects. Also known as delta-9-tetrahydrocannabinol, THC is the main ingredient responsible for the “high” associated with marijuana use. But this compound is one of over 100 cannabinoids identified in the cannabis plant, each of which contribute to the overall effects.

THC is available in multiple forms. These include dried flowers, hash, extracts, edibles, and more. With so many formats, there are also so many ways to consume it, including smoking marijuana, vaping, dabbing, and eating cannabis products.

THC may be best known for its fun recreational properties, but it is a critical component of medical marijuana, offering potential therapeutic benefits.

Wait a Minute, What are Cannabinoids?

Cannabinoids, the active substances in cannabis, include a diverse group of compounds, with THC being one of the most famous. All cannabinoids interact with the body’s endocannabinoid system, a complex network of receptors that regulate a variety of physiological processes. This interaction adds to the myriad effects we all know and love from the plant.

How THC Works in the Body

The magic of THC lies in its interaction with the body’s cannabinoid receptors. There are two main receptors, CB1 and CB2, but THC primarily interacts with CB1. When THC enters the bloodstream, it binds to the CB1 receptors, which are part of the endocannabinoid system. This binding initiates a cascade of physiological and psychoactive effects, influencing everything from pain perception to appetite to mood.

CB1 receptors are predominantly located in the central nervous system, including the brain. These receptors are crucial for regulating pain, mood, appetite, and memory. When THC binds to CB1 receptors, it can alter behavior, uplifting mood, reducing discomfort, and creating the sensation of a body buzz. It can also change appetite cues, resulting in the munchies.

In contrast, CB2 receptors are found mainly in the peripheral nervous and immune systems. These receptors are essential for modulating immune responses and pain interactions. The binding of THC to CB2 receptors isn’t as strong, but its relationship to CB2 may also help with inflammation, physical discomfort, and more.

THC’s effects on the brain are particularly interesting. It increases blood flow to the prefrontal cortex, the region responsible for complex cognitive behavior, decision-making, and moderating social behavior. This increased activity can heighten sensory perception and emotions, contributing to the psychoactive experience or the “high.”

Medical Uses of THC

These medical uses of THC illustrate its versatility and potential as a therapeutic agent. However, it is crucial to approach its use wcautiously given the variability in individual responses and the need for precise dosing.

THC for Cancer and Chemotherapy Induced Nausea and Vomiting

Medical cannabis has potential to alleviate symptoms of a long list of medical conditions, and THC plays a pivotal role. The FDA has approved specific medications that use synthetic cannabinoids, such as dronabinol and nabilone, for treating chemotherapy-induced nausea and vomiting. These medications mimic THC’s effects, providing relief for patients undergoing intense treatments.

Dronabinol is also approved for addressing appetite loss and weight loss in HIV/AIDS patients. While these medications are synthetic versions of THC, they help establish the medicinal value of the cannabis plant’s natural cannabinoids as equally useful as medicine.

THC for Multiple Sclerosis

Patients with multiple sclerosis frequently experience various types of pain, including neuropathic, musculoskeletal, and mixed pain. While cannabis is not uniformly effective for all pain types, its potential for managing challenging pain conditions highlights the need for tailored cannabinoid therapies, often with a THC component.

THC for Pain

One of the most significant benefits is its analgesic properties. Cannabinoids, including THC, may provide pain relief by activating non-cannabinoid receptors like TRPV1 and influencing pain signaling pathways. This mechanism offers a promising avenue for managing chronic pain, a condition that affects millions of people worldwide.

THC for Appetite

THC’s ability to stimulate appetite is another well-documented benefit. This effect is particularly valuable for patients experiencing severe weight loss due to conditions like HIV/AIDS or cancer. THC’s appetite-stimulating properties help patients maintain weight and enhance their quality of life.

THC for Mental Health

Beyond physical health, THC may also offer mental health benefits. Some users report relief from anxiety and depression, but these effects haven’t been proven in scientific studies. They can also vary widely based on the individual. It is essential to approach these potential benefits with caution, as THC can also exacerbate mental health conditions in some individuals.

As more states adopt medical cannabis laws, the potential benefits of THC are becoming more accessible to patients in need. However, balancing these benefits with a thorough understanding of the risks is crucial. Because all medicine, even cannabis plant-based medicines, come with some level of risk.

Legal Status of THC

THC’s legal landscape is complex because of the intricacies of federal and state laws. Despite the growing acceptance of medical marijuana and now even recreational marijuana, THC remains illegal at the federal level in the United States. The Drug Enforcement Administration (DEA) classifies THC alongside other Schedule 1 substances, indicating a high potential for abuse and no accepted medical use. While this classification may not reflect the science, it’s still the legal reality in which this plant finds itself.

Now, the federal classification contrasts with the state-level laws. At this point, a majority of states have enacted laws allowing the use of THC for medical purposes, and dozens have gone one step further to legalize recreational use. Still, this patchwork of regulations creates a complex legal environment for people seeking THC-based solutions.

For instance, while some states have robust medical cannabis programs, others have stricter regulations or outright bans on THC. This inconsistency can create challenges for patients seeking access to THC for therapeutic purposes, especially if they are far from home.

Marijuana legalization remains a contentious issue, with ongoing debates about its potential benefits and risks. Proponents argue that legalization can provide significant medical and economic benefits, while opponents raise public health and safety concerns.

Understanding the legal status of THC is crucial for anyone considering its use, whether for medical or recreational purposes. Staying informed about current laws and regulations can help users navigate this complex environment and ensure compliance with local and federal laws.

Safety Concerns and Precautions

While THC offers potential benefits, it is not without risks. One of the primary safety concerns is the risk of cannabis use disorder. Regular use of THC may lead to dependence.

Cannabis Use Disorder (CUD) is a medical condition characterized by problematic cannabis use that leads to significant impairment or distress. It is recognized in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and encompasses a range of symptoms related to the overuse of cannabis despite negative consequences. For example, it may actually cause nausea and vomiting instead of preventing it. While dependence on cannabis looks a lot different than other substances prone to drug abuse, it is, nevertheless, still a risk.

Adverse health effects are another significant concern. THC can impact mental health, potentially exacerbating conditions like anxiety, depression, or underlying cases of schizophrenia. It can also impair cognitive function and motor skills, increasing the risk of accidents and injuries, particularly motor vehicle crashes. These effects highlight the need for caution, especially when using THC in situations requiring full cognitive and motor function.

Finally, there are some concerns with smoking cannabis. Over time, smoking cannabis may harm lung health due to the inhalation of fine particulate matter in the smoke. It could cause respiratory issues with chronic use, but studies show this tends to clear up when the smoking stops. The good news is that there are other ways to enjoy cannabis and reap its benefits than inhaling it.

THC vs. CBD: Key Differences

THC and CBD, two of the most well-known cannabinoids, share a very similar chemical formula but differ in their atomic arrangement, leading to their distinct properties—this difference in structure results in different effects on the body and mind.

The primary source of THC is marijuana, which is explicitly bred for higher THC content compared to hemp. In contrast, CBD is more commonly derived from hemp, which contains lower levels of THC. These days, through advanced extraction processes, it’s possible to convert CBD into THC, but this process can be expensive.

THC induces a euphoric high, making it the compound responsible for the psychoactive effects of cannabis. In contrast, CBD does not produce any psychoactive effects, making it a popular choice for those seeking the therapeutic benefits of cannabis without the high. This difference makes CBD more widely accepted for wellness and legally available in most states.

THC and CBD interact with the endocannabinoid system but affect the body differently. THC’s interaction with CB1 receptors leads to its psychoactive effects, while CBD’s interaction with these receptors is less direct and does not produce a high.

Drug tests are more likely to detect THC, as it is the compound responsible for the psychoactive effects of cannabis. CBD, on the other hand, may not show up on standard drug tests unless specifically tested for. This isn’t guaranteed, however, so if you have a drug test in the future, it’s best to take a break from all cannabinoids.

Research and Clinical Trials

While the FDA hasn’t approved THC or cannabis specifically for any conditions, the research is very compelling. For example, studies show that medicinal cannabis can effectively reduce chronic pain, with meta-analyses revealing it is more effective than a placebo for achieving 30–50% reductions in pain scores and significant decreases in pain intensity.

THC has also demonstrated particular success in managing specific pain conditions, including neuropathic pain, multiple sclerosis-related pain, chemotherapy-induced pain, and fibromyalgia. These findings highlight cannabis’s potential as a therapeutic option for individuals with persistent pain conditions.

Current research on cannabis and pain management is focusing on the mechanisms by which cannabinoids may alleviate pain. These studies aim to uncover how THC and other cannabinoids interact with the body’s pain-signaling pathways, providing insights that could lead to more effective treatments.

Other studies have found medical marijuana has short-term benefits for sleep. THC initially helps improve sleep by reducing the time it takes to fall asleep and increasing total sleep time. It primarily increases deep, slow-wave sleep while reducing REM sleep, which is when most dreaming occurs.

As the body of research grows, we can expect to see more evidence-based guidelines for the use of the cannabis plant, including THC, in medical practice.
