Zera Hemp Labs 101: Glossary Of Terms

Since the 2018 Farm Bill, the distribution of hemp has become federally legal. Hemp’s dominant compound cannabidiol (CBD) continuously trends within the market, and as the years go by, the influence of hemp and CBD increases along with the need for information.

However, there is more to this industry beyond hemp and CBD. There is much to learn about the structures, compounds, and complexities of the plant. We believe these resources are helpful for people interested in expanding their knowledge and awareness of the hemp industry.

Here is our comprehensive glossary of common concepts and terms that one may encounter when learning about the cannabis plant:




2-AG is the most prevalent endocannabinoid in the body. Also known as 2-Arachidonoylglycerol, this endocannabinoid is a part of a group of molecules that play an essential role in several bodily processes like immunity and inflammation.

2-AG is known to regulate appetite, immune system function, and pain management by interacting with the body’s endocannabinoid system receptors.


An ingredient or product is activated once it has undergone heating, also referred to as decarboxylation. This procedure transforms the component from its natural form to its activated state and becomes more beneficial for the user.


Aeroponics is a cultivation technique where plants are grown in an environment that is dependent on air instead of soil. In this process, seeds are planted in foam then placed into tiny pots that hold the stem. The plants are nurtured with light and a mist enriched with nutrients.

Agricultural hemp

Agricultural hemp is a variety that contains less than 0.3% of THC concentration per dry weight of the plant. 

Alcohol extraction 

Alcohol extraction is done to extract cannabinoids from cannabis plants. The cannabis is first soaked in alcohol, such as ethanol, to remove the plant material. The alcohol is removed through evaporation.


Anandamide is a major endocannabinoid naturally found in the body. Like 2-AG, anandamide is a part of the body’s endocannabinoid system, altering functions like memory, cognition, mood, learning, and various motor functions. THC produces psychoactive effects and alters these functions in the body by how it mimics the way anandamide interacts with the endocannabinoid system.


Aroma pertains to the variety of scents for each strain. Some examples of strain aromas are citrusy, musky, or earthy. 



Bioavailability refers to the rate at which the body’s system absorbs a drug. It is an important measurement tool as it determines the proper dosage for non-intravenously administered drugs. 


Broad-spectrum products fall between full-spectrum and isolate products. Broad-spectrum products offer some benefits of the entourage effect (the combined therapeutic effect of cannabinoids and terpenes) because they contain both terpenes and cannabinoids, except for THC.

For people who cannot have or do not want traces of THC in their system, broad-spectrum products are a more suitable choice than isolates. However, they are not as effective as full-spectrum products.


A bud is an embryonic plant shoot, also known as the flower of a mature cannabis plant. The buds are harvested as they contain the highest concentration of active cannabinoids.


Cannabichromene (CBC)

Cannabichromene is one of the 120 cannabinoids found in the cannabis plant. CBC is a non-psychoactive cannabinoid, meaning it does not evoke a high sensation.

Cannabidiol is one of the most prevalent cannabinoids in cannabis. Cannabidiol (CBD) is renownedly known to treat and relieve a vast array of medical complications. Research also suggests that it is helpful for the treatment of anxiety, inflammation, and pain.

Cannabidiol extract (CBD extract)

Farmers extract CBD from the plant, which ensures the absence of any THC. Void of any psychoactivity, CBD extract is derived from the hemp plant and can be used for various health and wellbeing purposes.

CBD extract comes in oil form and can range from full-spectrum (all cannabinoids and terpenes), broad-spectrum (all terpenes and cannabinoids except THC), and isolate (pure CBD).

Cannabidiol isolate (CBD isolate)

CBD isolate is a powder that is created from a single CBD molecule. In its powder form, the isolate takes on a crystal-like consistency. The process also removes other cannabinoids, terpenoids, and plant materials to create a compound that is an active ingredient in various CBD products.

Cannabidiol oil (CBD oil)

CBD oil is made from extracting CBD from the hemp plant, then diluting it with a carrier oil like hemp seed oil or coconut oil. CBD oil is commonly used as an ingredient in cannabis tinctures, vaporizers, topicals, capsules, edibles, and other products.


Any of the several naturally occurring chemical constituents of cannabis or hemp, including some that possess intoxicating properties, such as THC, THCV, and CBN.

Cannabinoid 1 (CB1) receptor 

CB1 receptors help regulate biological function. CB1 receptors are found in several regions of the brain and spinal cord. These receptors regulate the effects of cannabinoids on these body organs.

Cannabinoid 2 (CB2) receptor 

CB2 receptors are present in the white blood cells and the immune system. CB2 receptors regulate the effect of cannabinoids on these cells and body organs.

Cannabinoid profile 

A cannabinoid profile is shown on a Certificate of Analysis (COA), depicting the concentration of active cannabinoids in a product or sample.


Cannabinol is a crystalline, mildly intoxicating cannabinoid found in small quantities in the cannabis plant. Cannabinol is a product of THC, meaning it has a strong sedating effect.


Cannabis refers to the three varieties of plants: Cannabis sativa, Cannabis indica, and Cannabis ruderalis. Cannabis contains more than 120 cannabinoids, which are the chemical components found in the plant.

Cannabis indica 

Also known as marijuana. Cannabis indica is a strain of cannabis known for its higher concentrations of THC. The strain is most known for its sedative properties. Because it contains high concentrations of THC, it is famous as a recreational and psychoactive strain.

Cannabis sativa

Also known as hemp. This herbaceous plant has been harvested throughout human history. It is farmed for marijuana and hemp. Additionally, hemp seed oil and hemp fiber are derived and gathered from different parts of this plant.


Capsules are one of the delivery methods for CBD oils and extracts, known for their convenience in being easy to consume. 


CBDA is the raw and acidic form of CBD. This acidic form is in its natural state and has not been altered in any manner.

Certificate of Analysis (COA)

A COA is a document from an accredited laboratory certifying the number of cannabinoids in a sample or product. The report exists to benefit the consumer as much as the producer. It guarantees quality assurance for both parties.

Having a valid COA helps to avoid mislabeled, low-quality, or fake products. A reputable company and laboratory will always provide one.

CO2 extraction

The carbon dioxide extraction process utilizes changes in pressure and temperature to create changes in carbon dioxide, drawing out the plant’s components. The result is a clean and safe oil with a long shelf life.

Concentrates (or extracts) 

Cannabis concentrates are significantly more potent than standard cannabis buds or flowers. They are processed to maintain only the most therapeutic compounds while removing excess plant material. Concentrates are usually developed for medical applications.


Cross-breeding is the process of breeding various cannabis plants to produce a new strain. After cross-breeding, the new strain adopts traits from both parent plants, ranging from potency, flavor profile, appearance, and more.

A cultivator is an individual who grows cannabis plants (hemp or marijuana), usually with a focus on soil quality and plant health.


A process that preserves the cannabis plant and retains its terpenes and therapeutic properties. Curing entails removing moisture from the flowers under controlled environmental conditions.



Dabs are concentrated doses of cannabis formulated by extracting CBD or THC using a solvent like butane; the result is reminiscent of wax. CBD dabbing is known for its immediate therapeutic effects.

Delivery method

Delivery methods pertain to how a drug enters the body to produce the desired therapeutic effects. The delivery method of a drug affects how quickly it starts to work. Some delivery methods include ingestible capsules, gummies, and tinctures, as well as topical lotions, salves, and lip balms.

Delta-9 tetrahydrocannabinol

Known the most for its abbreviation of THC, this is a primary cannabinoid found in cannabis. THC is responsible for psychoactive effects. It affects endocannabinoid receptors in the brain and spinal cord. Some do not prefer the high feeling or other side effects of the compound and prefer hemp-based products which contain less than 0.3% of THC.


Dispensaries are designed to give people a safe and secure location to gather information and purchase cannabis products. Laws regarding access vary by state.


Dosing is the quantity of medicine that is prescribed for an application. Dosing depends on therapeutic goals, as well as how it is ingested and applied.



Edibles are food that contains some form of hemp or medical cannabis. Edibles come in many forms: candy, coffee, baked goods, martinis, butter, and cooking oil.

Endocannabinoid enhancer 

An endocannabinoid enhancer is a drug that enhances the activity of the endocannabinoid system.

Endocannabinoid receptors 

Endocannabinoid receptors are found throughout the body and interact with the compounds in cannabis. There are two types of endocannabinoid receptors: CB1 receptors and CB2 receptors.

Endocannabinoid system

Also known as the ECS, the primary function of this mammalian system is to maintain bodily homeostasis or keep the body balanced even when the environment changes.

Scientists believe that cannabis is effective because phytocannabinoids mimic endocannabinoids. Endocannabinoid receptors are found throughout the body, and the system plays a role in many of the body’s processes, including appetite, sleep, stress, pain, memory, and immune function.

Entourage effect

The entourage effect is all about teamwork. It results from the many components in the cannabis plant interacting together with the human body to produce a more substantial effect than any single component on its own.

Full-spectrum CBD products incorporate CBD with other naturally occurring terpenes and cannabinoids to be more effective than their isolate states.

Ethanol extraction

Ethanol extraction is the method of using high-grade alcohol to gently pull the active compounds from the plant, resulting in pure hemp oil. Oils extracted using this method are further extracted with chromatography to remove the remaining traces of ethanol.

Extraction is the process of attaining CBD oil from hemp. There are various methods of extracting CBD from cannabis plants, including CO2 and cold ethanol extraction.
