A vast array of neurotransmitters are produced by the nervous system in response to various states of health and also environmental factors. They interact with receptors found on the surface of cells throughout our bodies. Their job is to instruct a cell to adjust its activities. This can include changing how cells react to other neurotransmitters.

In order to illustrate how neurotransmitters work, let’s use an analogy. The brain doesn’t connect with every cell in your body, just like traffic officers can’t connect directly with every car on the road to be able to instruct individual drivers how to behave in every traffic situation. In order to manage traffic, we implement traffic signals. These include street signs, traffic lights, the lines on the road and so on. Traffic signals inform drivers where they can and cannot travel, when they should stop and when they should go and how fast they are allowed to move. 

Some of these signals can sense what’s going on in the environment, such as when a car pulls up to a traffic light. The sensor triggers a controller, causing the light to change, thereby changing the behavior of the drivers approaching that intersection.

Now that we understand how neurotransmitters work to adjust our cellular activity, let’s take a look at the role of cannabinoids in particular and their role in supporting homeostasis, a state of balance, within the body.

The human endocannabinoid system (ECS) has two components. First is the endocannabinoid receptors found on the surface of cells throughout the body. Second is the endocannabinoids themselves that interact with those receptors.

For example, a well-known endocannabinoid is called anandamide. Anandamide is responsible for the production and uptake of serotonin. Serotonin is often referred to as the “bliss molecule” because levels of serotonin in the body are directly associated with mood. Serotonin is the neurotransmitter that is responsible for “runner’s high.”

The endocannabinoid system is vast and far-reaching. It regulates a wide array of bodily functions, from appetite regulation to sleep patterns, moods, metabolism, immune response, the lifespan of cells and much more.

Terpenes are a class of volatile hydrocarbon compounds produced by the cannabis plant as well as most other plants. However, cannabis is currently the most terpene-dense plant known to humans. Terpenes readily evaporate at room temperature and our noses are highly sensitive to them.

Terpenes are recognized as safe for human consumption by the Food and Drug Association (FDA) and are used in a wide variety of food and cosmetic products.

In nature, terpenes act as both a repellent for pests and as attractants for pollinators and seed spreaders.

Although terpene molecules are all very similar, each has its own unique scent and flavor. Various combinations of terpenes are responsible for the distinct aromas of cannabis strains.

Terpenes can also have powerful effects in our bodies. In fact, terpenes have been utilized by humans for millennia in what’s commonly known as aromatherapy. For example, the scent of citrus is produced primarily by a combination of limonene and pinene, both of which are thought to elevate mood.

Some common terpenes include linalool, myrcene, caryophyllene, limonene, terpinolene, citronellol and camphene. The traditional uses of these terpenes and others vary, but they include use as support for muscle and joint function, mood and overall wellness.

In cannabis, terpenes are produced in the highest concentrations in the plant’s female flowers. Terpenes also act on cannabinoid receptors and are known to modify the effects of cannabinoids.

This is worth touching on. Many companies will put CBD products on the market and make serious health claims about their product. These claims are not supported by the levels of scientific evidence that the FDA requires. These claims are a strong sign that a company is exaggerating what its product can do. Avoid those products.
