Quick answer

Quick Answer: What Are Cannabinoids?

Direct answer

Cannabinoids are chemical compounds that interact with the body’s endocannabinoid system or are structurally related to compounds found in cannabis and hemp. Some cannabinoids come from plants, some are made naturally by the body, and some are synthetic.

Simple answer: CBD and THC are cannabinoids. CBD is non-intoxicating, while THC is the primary intoxicating cannabinoid in cannabis. Full-spectrum CBD products may contain CBD plus other hemp compounds and trace THC.

Important caution: Cannabinoid research is still developing. Bluegrass Hemp Oil products are not intended to diagnose, treat, cure, or prevent disease.

Definition

What Are Cannabinoids?

Cannabinoids are part of the plant science and product-label vocabulary around hemp, cannabis, CBD, THC, and full-spectrum CBD products.

Cannabinoids are compounds associated with hemp, cannabis, and the body’s endocannabinoid system. In hemp and cannabis, cannabinoids are part of the plant’s natural chemistry. In the human body, endocannabinoids are signaling molecules that help the endocannabinoid system communicate.

Cannabinoids

A broad term for compounds related to the cannabis plant and the endocannabinoid system.

Phytocannabinoids

Cannabinoids produced by hemp and cannabis plants, such as CBD, THC, CBG, CBN, and CBC.

Endocannabinoids

Cannabinoid-like compounds made naturally by the body, such as anandamide and 2-AG.

Synthetic cannabinoids

Cannabinoid-like compounds made in a lab. Some synthetic or chemically converted products may carry extra safety and legal concerns.

Core categories

Three Main Categories of Cannabinoids

Understanding the categories helps explain why CBD oil labels, scientific articles, and legal discussions can use the word “cannabinoid” in different ways.

Category Plain-language meaning Examples Important context
Phytocannabinoids Cannabinoids made by hemp and cannabis plants. CBD, THC, CBG, CBN, CBC, CBDA, THCA These are the cannabinoids most often listed on CBD product COAs.
Endocannabinoids Cannabinoid-like signaling molecules made by the body. Anandamide, 2-AG These are part of the body’s endocannabinoid system.
Synthetic cannabinoids Cannabinoid-like compounds created in a lab or through chemical conversion. Synthetic research compounds, chemically converted intoxicating cannabinoids These require extra caution because safety, legality, and product quality can vary.

CBD vs THC

Major Cannabinoids: CBD and THC

CBD and THC are the most familiar cannabinoids, but they have different intoxication profiles and different product-label considerations.

Topic CBD cannabinoid THC cannabinoid
Full name Cannabidiol Tetrahydrocannabinol
Common source Hemp and cannabis Cannabis and some hemp products in trace amounts
Intoxication CBD is generally described as non-intoxicating. THC is the primary intoxicating cannabinoid in cannabis.
Product label role Usually listed as CBD, total CBD, or cannabidiol on a COA. Usually listed as Δ9-THC, THCA, total THC, or related THC entries on a COA.
Shopper takeaway CBD products may still carry side effects and medication-interaction concerns. THC exposure may matter for intoxication, drug testing, travel, workplace rules, and legal considerations.

CBD product caution

CBD is not risk-free, and most retail CBD products are not FDA-approved medicines. Talk with a qualified healthcare professional before using CBD, especially if you take medication, are pregnant or nursing, manage a medical condition, or are subject to drug testing.

Minor cannabinoids

Minor Cannabinoids: CBG, CBN, CBC, Acidic Cannabinoids, and Others

Minor cannabinoids are important for product identification, but this page does not make health-benefit claims for CBG, CBN, CBC, or other minor cannabinoids.

The phrase “minor cannabinoids” usually refers to cannabinoids that appear in smaller amounts than CBD or THC. They may be listed on a full-spectrum CBD certificate of analysis when the lab tests for them.

Cannabinoid What it is What to avoid claiming
CBG Cannabigerol, a phytocannabinoid sometimes discussed as a precursor molecule in cannabis chemistry. Do not turn CBG into a health-outcome claim.
CBN Cannabinol, a cannabinoid often discussed in relation to THC oxidation and product age or composition. Do not turn CBN into a sedating-positioned or proven-outcome claim.
CBC Cannabichromene, another naturally occurring phytocannabinoid that may be included on some cannabinoid panels. Do not turn CBC into a symptom or condition claim.
CBDA and THCA Acidic cannabinoids that can convert into CBD or THC through heat and time. Do not treat acidic cannabinoids as medical-treatment claims.
CBDV, THCV, and others Additional cannabinoids that may appear in research or advanced lab reports. Do not imply proven outcomes from presence on a COA.

Research context

Cannabinoid research is developing. A cannabinoid appearing on a lab report does not prove that a product treats, cures, prevents, manages, relieves, or improves any disease or symptom. For a focused explanation of acidic cannabinoids, read what CBDA is and how it differs from CBD.

Body science

Endocannabinoid System Overview

The endocannabinoid system is often shortened to ECS. Keep the concept educational and avoid claims that CBD “balances,” “restores,” or “optimizes” the ECS.

The endocannabinoid system is a signaling system discussed in relation to endocannabinoids, cannabinoid receptors, enzymes, and biological communication. Researchers continue to study how this system works and how plant-derived cannabinoids interact with it.

Endocannabinoids

Signaling molecules made by the body, including anandamide and 2-AG.

Receptors

Proteins such as CB1 and CB2 that are discussed in cannabinoid signaling.

Enzymes

Proteins that help create, move, or break down endocannabinoid signals.

Research status

The ECS is complex and still being studied. Retail CBD labels should not turn ECS science into disease claims.

Important language note

This page explains the ECS as a science topic. It does not claim that CBD, full-spectrum CBD, Genesis Blend, or any cannabinoid product balances the body or produces medical outcomes.

Receptor basics

CB1 and CB2 Receptors: A Simple Explanation

CB1 and CB2 are commonly discussed cannabinoid receptors, but the endocannabinoid system involves more than two switches.

Receptor Where it is commonly discussed Simple explanation
CB1 Often discussed in relation to the nervous system and brain. CB1 receptors are commonly associated with how cannabinoids can affect signaling in the nervous system.
CB2 Often discussed in relation to immune tissues and peripheral systems. CB2 receptors are commonly associated with immune and peripheral signaling.
Other pathways Researchers also study non-CB1 and non-CB2 pathways. The ECS is complex and still being researched.

Plant chemistry

Cannabinoids vs Terpenes

Cannabinoids and terpenes are both found in hemp and cannabis, but they are not the same thing.

Feature Cannabinoids Terpenes
What they are Compounds such as CBD, THC, CBG, CBN, and CBC. Aromatic compounds that contribute to plant scent and flavor.
Product label role Shown in cannabinoid profiles on COAs. May be shown in terpene profiles if tested.
Examples CBD, THC, CBG, CBN, CBC. Myrcene, limonene, beta-caryophyllene, pinene, linalool.
Common confusion People often confuse cannabinoid profiles with terpene profiles. Terpenes do not replace cannabinoid testing.

Lab reports

How to Read a Cannabinoid Profile on a COA

A certificate of analysis, or COA, helps verify what cannabinoids are present in a product.

A good COA should show CBD content, THC content, batch information, and contaminant testing. It helps shoppers compare what the label says with what a third-party lab reported for a specific batch.

A cannabinoid COA should help answer:

  • How much CBD is in the product?
  • How much THC is in the product?
  • Are minor cannabinoids listed?
  • Is the COA batch-specific?
  • Does the batch number match the product?
  • Was the product tested by a third-party lab?
  • Was it tested for heavy metals?
  • Was it tested for pesticides?
  • Was it tested for residual solvents?
  • Was it tested for microbes or contaminants?
  • Are results current?
  • Does the label match the lab report?

Safety first

Cannabinoid Safety: What to Know Before Using CBD Products

CBD products are not risk-free. Safety review matters before using CBD or comparing cannabinoid products.

FDA and CDC identify potential CBD risks, including liver-related concerns, medication interactions, drowsiness or sleepiness, digestive symptoms, appetite changes, and mood changes.

Safety topic Why it matters What to do
Medication interactions CBD may affect how some medications work. Talk with a qualified healthcare professional or pharmacist before use.
Liver-related concerns CBD may carry liver-related safety concerns. Ask whether CBD is appropriate if you have liver concerns or take medications.
Drowsiness and alertness CBD may cause drowsiness or changes in alertness. Do not drive or operate machinery until you know how a product affects you.
Alcohol and sedatives CBD with alcohol or sedating medications may increase sedation risk. Do not combine without professional guidance.
Pregnancy and nursing CBD use during pregnancy or nursing is not recommended. Talk with a qualified healthcare professional.
Children and pets Keep cannabinoid products away from children and pets. Use only appropriate products and professional guidance when relevant.

Professional guidance matters

Talk with a qualified healthcare professional before using CBD, especially if you take medication, are pregnant or nursing, manage a medical condition, or are subject to drug testing.

THC clarity

THC, Drug Testing, and Legal Caution

Full-spectrum CBD products may contain trace THC. THC exposure may carry drug-test risk.

Full-spectrum CBD products may contain trace THC. THC exposure may carry drug-test risk for people subject to workplace, legal, athletic, medical, military, or school testing.

Hemp and cannabinoid laws vary by state and may change. Do not assume cannabinoids or CBD products are legal in all states. Shoppers should check current state and local rules before buying or traveling with cannabinoid products.

Review THC content before buying if you:

  • Are subject to drug testing
  • Drive or operate machinery
  • Work in a regulated industry
  • Are in the military
  • Play competitive sports
  • Have legal or probation-related testing
  • Are sensitive to THC
  • Want to avoid intoxication

Extra caution

Synthetic and Intoxicating Cannabinoids: Why Extra Caution Matters

Not all cannabinoids sold online or in stores have the same safety profile.

Synthetic, chemically converted, or intoxicating cannabinoids may carry additional safety, legal, and testing concerns. Product labels can also be confusing when items are marketed as hemp while containing intoxicating THC-like compounds.

Use a higher caution standard

Review labels, COAs, state laws, and professional guidance before using intoxicating or synthetic cannabinoid products. Be especially cautious when a product’s labeling, testing, or ingredients are unclear.
