terpenes with cannabis

What are terpenes?

What are terpenes, and what do they have to do with cannabis?

Simply put; terpenes are what you can smell. You know that sweet and fruity scent you get from a fresh bud, or that first whiff of skunk as you open 'the jar'? Well, that's all down to terpenes just doing their thing. But, why does cannabis sometimes smell and taste different, and how does that difference translate to variations in benefits to the body? Read on to find out more.

Terpenes are naturally occurring compounds found in a mixture of the foods derived from plant matter that we all like to enjoy. Many of the cleaning products we see on store shelves utilise terpenes to give our homes a deep, clean scent. They have been deemed safe to consume, we encounter them daily. But how does this relate to cannabis? 

Well, they craft the delightful aromas you may find irresistible in many of the strains you enjoy. Terpenes account for a portion of the total dry weight of the cannabis plant—up to 5%. While CBD and THC have had the spotlight in recent years, terpenes have been lesser-known. In fact to most people this could be the first they’ve heard of terpenes, though they provide tons of potential benefits. They may also help to enhance many of the purported effects of other compounds in cannabis, such as THC and CBD as well. However, a big question on your mind may include whether terpenes can get you high. To uncover the truth, we’ve researched the science behind what terpenes are, and how they affect the body to give you the answer you’re looking for.

Take a second to zoom in on the below image.

Terpenes + Cannabis: An Analysis

Terpenes describe a group of chemical compounds that give both flavor and aroma to a variety of plants. This includes conifers, pines and the plants within the Cannabaceae family, or cannabis. In cannabis alone, there are hundreds of such components, although only a few feature prominently in most strains.

Terpenes serve an important purpose in plants. They are the first line of defense against predation. Although the smell of lavender, rose, and other scents may smell great to humans, for many organisms they function as a repellent. A terpene in this instance is commonly known to humans is citronella.

Terpenes are defined by most researchers as unsaturated hydrocarbons. These hydrocarbons are typically found in the resin that coats female cannabis plants, known as trichomes. Terpenes make up the essential oils of the cannabis plant.

Hydrocarbons are a class of molecular compounds that contain both hydrogen and carbon. Many thousands of terpenes occur naturally. The main types of terpenes found in cannabis include the following:

  • Myrcene
  • Humulene
  • Linalool
  • Limonene
  • α-pinene ( and also β-pinene)
  • Eucalyptol
  • Delta-III Carene

Many of these major terpenes can’t get you “high” on their own. Instead, that’s a distinction given to a more psychoactive ingredient in cannabis: THC. Although these components don’t get you high, they have an impact on how cannabis functions. They not only provide the flavors and aromas, but they work alongside THC, CBD, and a host of other phytochemicals and cannabinoids. This is known as the “entourage effect.”

The term was first coined by researchers S. Ben-Shabat and Raphael Mechoulam in 1998 during their research on the body’s endocannabinoid system, or ECS. They noticed that certain substances amplified the effects of some others in the body.

He states that terpenes work together to decrease the cognitive side effects that may be induced by THC while amplifying the medicinal benefits. He further contends that many of the cannabinoids – including terpenes – come together to reduce psychological side effects.The endocannabinoid system (ECS) is the body’s regulatory system. It is responsible for ensuring that basic functions stay within an acceptable range. The ECS includes much of the nervous system, some immune cells, and the brain. The brain uses signals from chemical messengers, called neurotransmitters.

Think of the ECS as a delivery system. The nerve cells are intricate transport systems, the neurotransmitters function as delivery operators and the brain is the central processing hub. These components work together to interpret and translate signals associated with pain, memory, temperature, and movement.

Cannabis mimics many of the body’s chemicals. These chemicals are known as endocannabinoids. Due to this similarity, cannabinoids, including terpenes, assist the body with residual side effects. Terpenes can be useful in a variety of ways.

They don’t simply provide smell and flavor. They may have therapeutic effects of their own. They have been historically used to treat a host of afflictions and maladies and each major terpene has its own set of chemical attributes that may support many bodily processes. Check out this great video!

Terpenes and Their Functions

Myrcene

Myrcene is one of the most prevalent terpenes found in cannabis. It has been utilized in history as an alternative medicine for myriad ailments, including dysentery and hypertension. It has been said to have a variety of calming attributes, including anti-inflammatory properties. It may also allow for easier transport of substances across the blood-brain barrier.

Limonene

Limonene is derived from the essential oils of citrus plants, such as lemons, limes, and oranges, hence its name. It is very popular in the household cleaner, food and perfume industries. Its tangy smell lends it well to a host of products, and it may possess beneficial antidepressant and anti-inflammatory properties.

Pinene

Pinene, as you may have guessed is what gives pine its fresh, clean scent. If you’ve ever taken a whiff of a kitchen cleaned with a “pure pine” disinfectant and loved the smell, pinene was the power behind it. Pinene comes in two different forms: Alpha and beta. It’s the alpha version that is most commonly found in cannabis.

Pinene has been indicated in recent studies as a bronchodilator, meaning it may help in opening up the lungs. This is important to those suffering from disorders that block passages in the lungs such as asthma and bronchitis. Pinene may also be able to balance out some of the cognitive effects of THC.

Linalool

Linalool has a strong aromatic profile. It is found in plants like lavender, which is a popular scent in many products on the market. Linalool is said to have anti-convulsant effects as well as anti-inflammatory properties.

Humulene

Humulene is a terpene that many people use to manage their weight. While some other terpenes support appetite increase, this terpene may help to decrease appetite. It can be found in plants like basil and clove. It is also often taken as a pain reliever and can be consumed orally, topically and even via aerosol.

Delta-III Carene

Delta III Carene is found in several plants, like rosemary, basil, bell peppers, and pine. It has a sweet and woody aroma while boasting a beneficial medical benefit: it may be able to heal broken bones. Patients suffering from fragile bone syndromes, including osteoporosis may be able to utilize this terpene.

It may also spur memory retention as well as point to a cure for Alzheimer’s disease.

Eucalyptol

Eucalyptol is an aromatic that has a minty, cool profile. It is often used in mouthwashes and cough suppressants. It is also known as cineole and can be found in plants such as the eucalyptus tree.

It has some tremendous medicinal benefits but doesn’t make up a huge portion of most strains. Some estimate that less than .06% of dry weight is made up of eucalyptol. It may not only stop the growth of dangerous bacteria and fungi, but it may also have some anti-inflammatory properties.

Terpenes Summary

It wouldn’t be relevant to label either terpenes or cannabinoids as being any better or worse than the other – in truth, it’s actually believed that they work in sync with one another rather than producing distinct, individualistic effects. 

What is widely believed to be true, however, is that terpenes – due to their influence on THC activity in the central nervous system – are actually what gives marijuana its distinct highs and varying psychoactive effects from strain to strain.

While we don’t know exactly the specific role that cannabis terpenes play in human physiology, we do know that without them, the medical, therapeutic, and psychoactive effects of cannabinoids like THC and CBD would not be nearly as relevant as they are.
