In recent years, there’s been a lot of buzz around CBD and THC, two key compounds found in marijuana. With the increasing legalization of marijuana, it’s important to understand the differences between these two substances and how they interact with our bodies.
Within our bodies, there’s a complex network known as the endocannabinoid system. This system plays a crucial role in regulating various functions such as mood, appetite, memory, and pain sensation. Both THC and CBD interact with this system, but they do so in different ways.
THC, or tetrahydrocannabinol, and CBD, or cannabidiol, have very similar chemical structures. They share the same molecular formula, C21H30O2, and have a mass of approximately 314 grams per mole. However, the key difference lies in their structures: THC contains a cyclic ring, while CBD has a hydroxyl group. This small structural variation significantly impacts their effects on the body.
The CB1 receptor is a part of the endocannabinoid system and is influenced by a neurotransmitter called anandamide. Anandamide is associated with feelings of pleasure and motivation and is released after activities like exercise, contributing to the “runner’s high.” THC’s structure closely resembles anandamide, allowing it to bind effectively to the CB1 receptor, which results in the psychoactive effects, or the “high,” associated with marijuana.
Unlike THC, CBD does not bind to the CB1 receptor due to its different structure. As a result, it does not produce a high. However, CBD interacts with other receptors in the endocannabinoid system, influencing the body in various beneficial ways.
Research has shown promising results regarding CBD’s potential therapeutic effects. A notable study from 2011 involved individuals with social anxiety disorder who were asked to speak publicly. Those who received CBD reported significantly reduced anxiety compared to those who received a placebo. Additionally, animal studies have highlighted CBD’s anti-anxiety and anti-inflammatory properties, which may explain its effectiveness in managing anxiety and chronic pain.
Interestingly, research indicates that THC may worsen psychotic symptoms, while CBD might help alleviate them. This distinction highlights the importance of understanding the specific effects of each compound.
When THC and CBD are consumed together, they can influence each other’s effects. A study found that CBD can bind to the CB1 receptor and inhibit THC’s ability to bind, a process known as allosteric inhibition. This means that CBD can reduce the intensity of the high produced by THC. For instance, consuming marijuana with a high THC content and low CBD content will result in a stronger high. Conversely, a higher CBD content can lead to a milder high.
In regions where marijuana is legally available, products often display the percentages of THC and CBD. This information helps consumers understand the potential effects on their bodies. In summary, THC is the compound responsible for the high associated with marijuana, while CBD has a different structure and does not produce a high but offers other potential benefits.
There is still much to learn about THC and CBD, and ongoing research is crucial. As more states and countries legalize marijuana, increased research efforts will hopefully provide deeper insights into how these compounds affect us.
In light of marijuana’s legalization in Canada, a new series called “Stoned Science” has been created. In this series, comedians explore complex scientific concepts while under the influence of marijuana. The first episode focuses on the respiratory system, offering a unique and entertaining educational experience.

Everyone is talking about CBD and THC, which are two important compounds found in marijuana. With marijuana legalization becoming mainstream, what is the actual difference between CBD and THC?
Inside your body, there’s a biological pathway at work called the endocannabinoid system, which helps regulate your mood, appetite, memory, and pain sensation. THC and CBD interact with this system.
This is the chemical structure of THC, also known as tetrahydrocannabinol, and this is the chemical structure of CBD, also known as cannabidiol. You may notice that their chemical structures are almost identical; they have the same molecular formula, C21H30O2, and both have a mass of approximately 314 grams per mole. However, there is one significant structural difference: THC contains a cyclic ring, while CBD contains a hydroxyl group. This difference in biochemistry affects whether or not you feel high.
To understand this, you need to know about the CB1 receptor in your body. The CB1 receptor is influenced by a neurotransmitter called anandamide, which plays a role in pleasure, motivation, and feeding behavior. Anandamide is released after exercise and contributes to the feeling known as a “runner’s high.” THC’s structure is similar to anandamide, allowing it to fit perfectly into the CB1 receptor, which is why it produces a high.
On the other hand, CBD, due to its hydroxyl group, has a different shape and does not bind to the CB1 receptor, so it does not produce a high. However, CBD does interact with other receptors in the endocannabinoid system, affecting the body in various ways.
A notable study from 2011 involved individuals with social anxiety disorder who were asked to speak in front of a large audience. Some received CBD, while others received a placebo. Those who received CBD reported significantly less anxiety. Additionally, many animal studies have shown CBD’s anti-anxiety and anti-inflammatory properties, which may explain why some people find it helpful for anxiety and chronic pain.
Research is also revealing that THC can exacerbate psychotic symptoms, while CBD may help alleviate psychosis.
What happens when you consume both THC and CBD together? One study found that CBD can bind to the CB1 receptor and inhibit THC’s ability to bind, a process known as allosteric inhibition. This means that CBD can reduce the intensity of the high produced by THC. For example, if you vaporize marijuana with 25% THC and 0.1% CBD, you will feel high, as the THC binds to the CB1 receptor with minimal interference from CBD. However, if you consume marijuana with 25% THC and 12% CBD, the higher CBD content will inhibit THC’s binding to the CB1 receptor, leading to a milder high.
In places where marijuana is legally sold, products typically indicate the percentages of THC and CBD, helping you understand their effects on your body. In summary, THC is a compound in marijuana that produces a high, while CBD has a different structure and does not produce a high but can affect the body in other ways.
There is still ongoing research and much to learn about both compounds. With more states and countries legalizing marijuana, hopefully, increased research will provide further insights into how these two compounds affect us.
Since marijuana is now legal in Canada, we created a new series called “Stoned Science,” where comedians get high and attempt to explain complex scientific concepts. Our first episode is about the respiratory system, so click here to watch it and share your thoughts as we continue to develop this new idea.
