• We review what researchers have learned about CBD.
• We cover CBD safety, possible side effects, and the different product types and how they’re used.

Have you ever wondered how the body keeps itself in balance? The endocannabinoid system is one part of that process and helps regulate several normal bodily functions.

CBD has become widely used in recent years. Cannabidiol, better known as CBD, is a natural compound that may interact with this system. Let’s take a closer look.

What is the endocannabinoid system?

The endocannabinoid system (ECS) is a key cell-signaling system found throughout the human body.

The Role and Functions of the Endocannabinoid System

The ECS helps maintain the body’s internal balance, or homeostasis, and supports several normal physiological processes as conditions change.

The ECS is involved in several body functions, including:

• Sensory processing
• Mood and stress response
• Sleep and wakefulness
• Appetite and metabolism
• Immune function
• Inflammatory processes
• Well-being and mood
• Cognitive function

The historical background of cannabinoids

Scientists discovered the endocannabinoid system in the early 1990s, which expanded our understanding of human biology. In cannabis research, they identified key molecules such as anandamide in 1992 and 2-arachidonoylglycerol (2-AG) soon after.

What endogenous means

Endocannabinoids are compounds your body makes naturally. The term “endogenous” means “produced inside the body.” Their levels can vary, so there isn’t one ideal concentration for everyone.

Endocannabinoids in the Human Body

Anandamide and 2-AG are endocannabinoids made by the body. They circulate throughout the body and bind to receptors on cell membranes, helping support this important signaling system.

Endocannabinoids can bind to either of these receptors. Their effects depend on where in the body the receptors are located.

If the body is under stress from things like injury or heat, the ECS helps keep it in balance. Researchers generally describe homeostasis as the body’s internal state of balance.

Skin Receptors and the Endocannabinoid System

These receptors are found throughout the body. Endocannabinoids bind to them and signal that the ECS needs to respond.

There are two main endocannabinoid receptors:

• CB1 receptors — mostly found in the central nervous system.
• CB2 receptors – Found in the peripheral nervous system, especially on immune cells.

Endocannabinoids can bind to either receptor, and the effect depends on where in the body the receptor is located.

Enzymes

Enzymes break down endocannabinoids after they’ve done their job. Two main enzymes are involved:

• Fatty acid amide hydrolase (FAAH), an enzyme that breaks down anandamide.
• Monoacylglycerol lipase (MAGL), an enzyme that breaks down 2-AG.

 

We’ve seen how the ECS and the body’s endocannabinoids play important roles in normal bodily processes. Now let’s look at how this system interacts with cannabinoids like CBD and THC.

THC and Its Interaction with the Endocannabinoid System

Tetrahydrocannabinol (THC) is one of the main cannabinoids found in cannabis and is known for its psychoactive effects. In the body, THC interacts with the endocannabinoid system and can influence several physiological processes.

What CBD Is and How It Relates to the Endocannabinoid System

Another major cannabinoid in cannabis is cannabidiol (CBD). Unlike THC, CBD is not known for mind-altering effects.

Like THC, CBD may interact indirectly with receptors in the endocannabinoid system (ECS).

The relationship between CBD and anandamide

Anandamide is a key endocannabinoid in the human body. CBD has been studied for how it may interact with anandamide, but more research is needed.

How CBD May Interact with Endocannabinoid Receptors

Unlike THC, CBD does not bind directly to CB1 and CB2 receptors. Instead, it may influence them indirectly in the following ways:

• It may change receptor shape, which can affect how other cannabinoids bind.
• It affects receptor signaling.
• It can influence endocannabinoid activity without directly binding to receptors.

How CBD works

CBD’s effects may go beyond the endocannabinoid system because it also:

1. Researchers are still studying whether CBD interacts with serotonin receptors.
2. CBD interacts with vanilloid receptors, and researchers are still studying what that means.
3. Some research has explored CBD’s antioxidant activity and inflammation-related processes.

What Research Says About CBD

Now that we understand the connection between CBD and the endocannabinoid system, let’s look at what research says about CBD.

CBD and sleep

Research on CBD and sleep is still developing. Some studies have explored whether CBD may affect sleep quality, but the findings are mixed and more research is needed.

CBD Research: An Overview

A 2022 review discussed CBD in early-stage research, but the evidence is still preliminary and not a basis for product claims. More human research is needed.

CBD and the nervous system

Researchers are still studying CBD’s effects on brain function, but the evidence is limited and not conclusive.

CBD Research on Mood-Related Topics

Some studies have explored CBD’s possible effects on mood, but the research is still early and the results are not conclusive.

CBD Research on Inflammation and Related Topics

CBD has been studied for its possible role in the body’s inflammatory response, but more research is needed, especially in humans.

The benefits listed here are promising, but more research is needed to understand CBD’s safety and how it works.

CBD safety and side effects

Possible CBD side effects

Some people may experience mild side effects from CBD, including:

• Dry mouth
• Tiredness
• Changes in appetite
• Diarrhea
• Weight changes

CBD and drug interactions

CBD can interact with certain medications. Talk with a doctor before use. Key points:

• CBD can affect the CYP450 enzyme system, which may change how the body processes some medications.
• Use extra caution if you take blood thinners, anti-epileptic medications, or immunosuppressants.

CBD dosing

When choosing a CBD product, consider these factors:

1. Start with a low dose and increase gradually while paying attention to how your body responds.
2. CBD is not recommended during pregnancy or while breastfeeding.
3. Talk to a healthcare professional before use if you have a chronic condition or take regular medications.
