What is THC?

THC, or tetrahydrocannabinol, is a compound found in the cannabis plant that has a significant impact on the brain and body. Let's break down what THC is by looking at its chemical structure, psychoactive effects, and interaction with cannabinoid receptors.

Chemical Structure

THC has a specific chemical makeup consisting of 21 carbon atoms, 30 hydrogen atoms, and 2 oxygen atoms. Its molecular structure is similar to another compound in the cannabis plant, CBD, but the arrangement of atoms differs. This difference in structure is why THC has psychoactive effects, while CBD does not.

Psychoactive Effects

THC is best known for its psychoactive effects—it's the component in cannabis that makes you feel "high." When you consume THC, it affects your brain's endocannabinoid system, which influences pleasure, memory, and concentration. It binds to cannabinoid receptors in the brain, leading to feelings of euphoria and relaxation. This effect is due to THC prompting the brain to release dopamine, a neurotransmitter that plays a major role in the feelings of pleasure.

Cannabinoid Receptors

Our brains are equipped with cannabinoid receptors, which are part of the endocannabinoid system. This system helps regulate various physiological processes, including pain sensation, mood, and memory. THC binds to these receptors, specifically the CB1 receptors located in the brain and nervous system, altering normal brain communication. This is why THC can affect how you think, and perceive the world around you.

Understanding what is THC and how it interacts with your body explains why it has such potent effects, both mentally and physically. It's not just about the high; it's about how THC taps into the natural cannabinoid system in your brain, influencing everything from your mood to how you perceive time. As we explore further, we'll see how these effects translate into both medicinal benefits and risks.

Sources and Forms of THC

THC, or tetrahydrocannabinol, is the chemical responsible for most of marijuana's psychological effects. It acts much like the cannabinoid chemicals made naturally by the body. Cannabinoid receptors are concentrated in certain areas of the brain associated with thinking, memory, pleasure, coordination, and time perception. THC attaches to these receptors and activates them, affecting these various functions.


Marijuana is the dried leaves, flowers, stems, and seeds from the Cannabis sativa or Cannabis indica plant. It contains the mind-altering chemical THC, among other similar compounds. Marijuana is the most common form of cannabis and is typically smoked, but it can also be added to foods (edibles), brewed as tea, or inhaled with vaporizers.

Hash and Hash Oil

Hash is made from the resin of the cannabis plant and is compressed into a variety of forms such as balls, cakes, or cookie-like sheets. Its THC concentration is higher than that of regular marijuana flowers. Hash oil, the most potent cannabis product, is a thick oil obtained from hashish or marijuana which might contain various amounts of THC. The oil is usually consumed by smoking, using a vaporizer, or ingesting orally.


Edibles are foods and beverages containing marijuana or marijuana oils. Edibles can be homemade or prepared commercially for dispensaries. When you consume these products, the THC level in edibles can vary, and the effects might not be felt immediately, leading to a risk of overconsumption.

Synthetic THC

Synthetic cannabinoids, like Spice or K2, are human-made chemicals that can be sprayed on dried, shredded plant material so they can be smoked or sold as liquids to be vaporized and inhaled in e-cigarettes and other devices. These products are often called "synthetic marijuana" or "fake weed," and they can affect the brain much more powerfully than marijuana; their actual effects can be unpredictable and, in some cases, more dangerous or even life-threatening.

Synthetic THC is also developed for medicinal use, where it is strictly regulated and its dosage is controlled. FDA-approved synthetic THC formulations include dronabinol and nabilone, which are used to treat nausea and vomiting caused by chemotherapy and to increase appetite in patients with extreme weight loss caused by AIDS.

The variety of THC sources and forms reflects its versatility but also underscores the importance of understanding its effects and risks. Whether used for medicinal purposes or recreational, knowing what form of THC you are interacting with can greatly influence your experience and its outcomes.

How THC Affects the Brain and Body

THC, or tetrahydrocannabinol, is the main psychoactive component in marijuana that affects the brain and body in various ways. Here, we'll explore how THC interacts with your brain and body, focusing on its psychological and physical effects.

Psychological Effects of THC

When you consume THC, it primarily affects the brain by binding to cannabinoid receptors. These receptors are part of the endocannabinoid system, which plays a crucial role in regulating mood, memory, appetite, and pain sensation. Here's how THC impacts different psychological aspects:

  • Pleasure: THC activates the brain's reward system by triggering the release of the chemical dopamine. This release causes the euphoria or the "high" associated with marijuana use.
  • Memory: THC affects the hippocampus, the area of the brain responsible for forming new memories. This can lead to difficulties in learning or recalling recent events while under the influence.
  • Coordination and Sensory Perception: THC impairs motor coordination and alters sensory perception, which can affect tasks that require fine motor skills or alter the way you experience sights, sounds, and time.
  • Time Perception: Many users report experiencing a distortion in time perception, where time seems to slow down.

The psychological effects can also include: - Euphoria: The feeling of being "high," a state of being happy, relaxed, and often unconcerned with surroundings. - Hallucinations: In high doses, THC can cause visual or auditory hallucinations. - Delusions: Some users may experience fixed, false beliefs that are not aligned with reality. - Anxiety: While THC can reduce anxiety in some users, it may increase it in others, especially at higher doses.

Physical Effects of THC

Alongside psychological effects, THC also has several physical impacts on the body: - Motor Skills: THC affects the cerebellum and basal ganglia, brain regions that regulate balance, posture, coordination, and reaction time. This can impair your ability to perform tasks that require coordination and fine motor skills. - Heart Rate: THC causes an increase in heart rate, which can be risky for people with heart conditions. - Respiratory Effects: Smoking marijuana can irritate the lungs and lead to issues similar to those found in tobacco smokers, including coughs, phlegm, and more frequent lung infections.

Each of these effects can vary widely among different individuals, influenced by factors such as the amount of THC consumed, the method of consumption, and personal tolerance levels.

Understanding these effects is crucial for anyone considering the use of THC, whether for recreational or medicinal purposes. It's important to approach THC use with awareness of its profound impact on the brain and body, ensuring informed decisions that prioritize safety and health.

Medicinal Uses of THC

FDA-Approved THC Medications

Dronabinol and Nabilone are two FDA-approved medications that contain synthetic forms of THC.

Frequently Asked Questions about THC

Navigating cannabinoids can be complex, especially when distinguishing between THC and CBD, understanding THC's interaction with the brain, and knowing its legal status. Here, we answer some common questions to clarify these points.

What's the difference between THC and CBD?

THC (Tetrahydrocannabinol) and CBD (Cannabidiol) are both cannabinoids found in the cannabis plant, but they differ significantly in their effects on the human body. THC is psychoactive, meaning it can alter brain function, resulting in temporary changes in perception, mood, consciousness, and behavior. Essentially, THC is the compound that makes you feel "high."

On the other hand, CBD does not have psychoactive effects and does not cause a high. Instead, it is often praised for its potential therapeutic benefits, helping with issues like anxiety, pain, and insomnia without the intoxicating effects of THC. This makes CBD a more appealing option for those seeking relief without the psychoactive experiences.
