An Introduction to CBD

Cannabidiol (CBD) is one of over 100 known cannabinoids found in Cannabis sativa. It’s among the most prominent active compounds inside cannabis plants, and its therapeutic potential has rapidly gained recognition as a preferred choice for those seeking natural wellness solutions. Recent scientific investigations continue to reveal CBD’s wide-ranging benefits, particularly through its interaction with the endocannabinoid system (ECS). The ECS functions as a complex biological network of cannabinoid receptors that help maintain homeostasis throughout the body, regulating crucial functions like sleep, mood, appetite, and immune response.

The ECS, in layman terms, is essentially a biological network of cannabinoid receptors which aid the human body in maintaining its overall health and wellness. 

On This Page This guide covers the fundamentals of CBD, including its sources, different product types, and key terminology. Whether you’re considering CBD for the first time or looking to deepen your understanding, you’ll find clear explanations about extraction methods, product formulations, and how to determine which options might best suit your needs.

CBD Basics

So What Exactly is CBD?

CBD is predominantly extracted from industrial hemp plants specifically cultivated for their high cannabidiol content and minimal THC levels.  While Hemp and Marijuana plants both come from the same species (Cannabis), CBD is usually extracted from hemp, and is grown with the goal of containing minimal levels of THC. According to federal law, industrial hemp must contain less than 0.3 percent THC. Hemp-derived CBD products offer the properties of the entire hemp plant (CBD, other cannabinoids, terpenes…) without the presence of the high-inducing THC.!

CBD is a type of phytocannabinoid. Phytocannabinoids are different than endocannabinoids, but both are cannabinoids. Endocannabinoids are produced naturally in the human body. Phytocannabinoids are organically synthesized in plants. Both Endo- and phytocannabinoids react to the same type of receptors in our bodies.

The extraction process typically involves using solvents (like CO2, ethanol, or hydrocarbon) to separate cannabinoids from plant material. Advanced extraction methods can isolate specific compounds or preserve the full spectrum of beneficial elements found naturally in the plant.

CBD vs. THC: Key Differences

While both CBD and THC originate from cannabis plants, they interact with your body in fundamentally different ways:

• Psychoactivity: THC produces the characteristic “high” associated with marijuana use. CBD does not cause intoxication.
• Legal Status: Hemp-derived CBD containing less than 0.3% THC is federally legal, while THC remains federally controlled (though legal in many states).
• Receptor Binding: THC binds directly to CB1 receptors in the brain, triggering psychoactive effects. CBD works indirectly, modulating receptor activity without strong binding.
• Side Effects: THC may cause temporary cognitive impairment, anxiety, or paranoia in some users. CBD generally produces minimal side effects, with some users reporting mild drowsiness or changes in appetite.
• Medical Applications: Both compounds show therapeutic potential, but for different conditions and through different mechanisms.

The Endocannabinoid System

The endocannabinoid system (ECS) represents one of the body’s most widespread signaling networks. Discovered in the early 1990s, this system plays a critical role in maintaining physiological balance across multiple functions.

The ECS consists of three core components:

1. Endocannabinoids: Naturally produced compounds (like anandamide) that serve as chemical messengers
2. Receptors: Primarily CB1 (concentrated in the brain and central nervous system) and CB2 (predominantly found in peripheral organs and immune cells)
3. Enzymes: Specialized proteins that synthesize and break down endocannabinoids

When the ECS functions optimally, it helps regulate sleep cycles, stress responses, inflammatory pathways, and numerous other processes essential to health. Phytocannabinoids like CBD can supplement this system, potentially addressing deficiencies or imbalances in natural endocannabinoid production.

Types of CBD Products

Full Spectrum vs. Broad Spectrum vs. Isolate

CBD products fall into three main categories based on their cannabinoid content:

Full Spectrum CBD contains all naturally occurring compounds found in the cannabis plant, including terpenes, flavonoids, and trace amounts of THC (up to 0.3%). Many users prefer full spectrum products for their “entourage effect”—the synergistic interaction between multiple cannabis compounds that may enhance therapeutic benefits.

Broad Spectrum CBD maintains most of the plant’s beneficial compounds but undergoes additional processing to remove THC. This option appeals to those who want multiple cannabinoid benefits without any THC exposure.

CBD Isolate is pure cannabidiol, typically exceeding 99% purity. All other plant compounds are removed through intensive filtration. Isolate products work well for those seeking CBD’s specific effects without other cannabis compounds.

CBD Product Types – or “Vessels”

Oils and Tinctures CBD oils consist of cannabidiol suspended in a carrier oil (typically MCT, hemp, or olive oil). Administered sublingually (under the tongue), this format offers relatively rapid absorption and precise dosing through graduated droppers. Effects typically begin within 15-30 minutes and may last 4-6 hours.

Edibles and Gummies These popular, pre-dosed products mask CBD’s natural taste while providing consistent amounts per piece. Digestion means slower onset (45-90 minutes) but potentially longer-lasting effects (6-8 hours). Ideal for those who prioritize convenience and discretion.

Topicals Creams, balms, and lotions infused with CBD deliver targeted relief to specific areas. Applied directly to the skin, these products interact with local cannabinoid receptors without entering the bloodstream significantly. Topicals work well for addressing localized concerns and typically begin working within minutes of application.

Capsules and Softgels Pre-measured CBD in convenient pill form offers consistent dosing without taste considerations. Like edibles, they pass through the digestive system, resulting in delayed onset but extended duration. Particularly suited for those incorporating CBD into existing supplement routines.

Vape Products Inhalation provides the fastest delivery method, with effects often noticeable within minutes. However, this rapid onset typically means shorter duration. Recent health concerns regarding vaping have led many users toward alternative consumption methods.

How to Choose the Right CBD Product

Consider Your Wellness Goals

Identifying your specific objectives is the first step in selecting the appropriate CBD product. Different formulations and delivery methods may be better suited for your particular needs:

• For overall wellness and balance: Full or broad spectrum tinctures taken daily often provide comprehensive support for the endocannabinoid system.
• For localized physical discomfort: Topical formulations allow for direct application to specific areas of concern, with minimal systemic absorption.
• For sleep support: Products combining CBD with complementary ingredients like melatonin, terpenes like myrcene, or minor cannabinoids like CBN may offer enhanced relaxation properties.
• For stress management: Fast-acting sublingual oils or tinctures can be beneficial when seeking more immediate effects during demanding situations.
• For digestive wellness: Oral products that pass through the digestive tract may provide more targeted support for gastrointestinal concerns.

The key is matching the product’s properties with your individual needs, rather than simply choosing based on a product’s current popularity or price point.

Understanding Potency and Dosage

CBD products vary dramatically in concentration, typically measured in milligrams of CBD per serving or container. When evaluating potency:

• Start low and go slow: Particularly for beginners, it’s advisable to begin with lower concentrations (10-25mg per serving) and gradually increase as needed.
• Calculate cost-per-milligram: Divide the price by total CBD content to determine value. Higher potency products often offer better value despite higher upfront costs.
• Consider your body weight: Generally, higher body weight may require higher concentrations for noticeable effects.
• Account for metabolism: Individual biochemistry significantly influences how CBD interacts with your system. Some people experience effects at very low doses, while others require substantially more.
• Be consistent: Daily use over several weeks often yields more pronounced results than occasional consumption.

Quality Indicators

Not all CBD products meet the same standards. Key quality markers include:

• Third-party laboratory testing: Reputable manufacturers provide comprehensive Certificates of Analysis (COAs) from independent laboratories verifying cannabinoid content, terpene profiles, and confirming the absence of contaminants like pesticides, heavy metals, and residual solvents. Read up on our COA explanations in full.
• Extraction method: CO₂ extraction generally produces the cleanest products, while ethanol extraction balances efficiency with quality. Avoid products using hydrocarbon extraction unless rigorous testing confirms solvent removal.
• Cultivation practices: Organic, regenerative, or sustainable farming methods minimize environmental impact and reduce potential contaminant exposure. Hemp’s nature as a bioaccumulator makes growing conditions particularly important.
• Company transparency: Look for brands that openly share their sourcing, manufacturing processes, and testing protocols rather than relying heavily on marketing claims.
• Product reviews and reputation: While subjective, consistent positive feedback from verified purchasers often indicates reliable quality.

Reading Labels

Understanding CBD product labels helps ensure you’re getting what you expect. Key elements to identify include:

• Total CBD content: Look for clear indication of total CBD per container AND per serving.
• Serving size information: Understand what constitutes a single dose (e.g., 1 dropper, 1 gummy).
• Type of CBD: Labels should specify whether the product contains full spectrum, broad spectrum, or isolate CBD.
• Carrier oils/ingredients: Quality carriers like MCT oil, hemp seed oil, or olive oil enhance absorption. For edibles and topicals, check for natural ingredients versus artificial additives.
• Batch/lot numbers: These allow traceability to specific test results and production runs.
• QR codes or links: Many premium products feature scannable codes linking directly to corresponding lab results.
• Usage instructions: Clear guidance on how to use the product properly.
• Warning statements: Legitimate products include appropriate cautions regarding use during pregnancy, potential medication interactions, or other relevant considerations.
