Glossary & Learning Center

Welcome to THC-Free CBD Hub’s Glossary & Learning Center. This page is a practical, plain‑English guide to key terms you’ll encounter when shopping for or learning about THC-free CBD products.

Use this thc free cbd glossary to get quick definitions and context around labels, lab reports, and product types—especially concepts like “ND,” LOQ/LOD, and what “THC-free” generally means in the market.

Quick-start guide to common terms

  • THC-free: A product marketed to contain non-detectable (ND) or negligible amounts of THC per its Certificate of Analysis (COA). “THC-free” is a marketing description; always verify with the latest batch COA.
  • CBD isolate: Purified cannabidiol with other cannabinoids and terpenes removed. Commonly used for THC-free products.
  • Broad-spectrum: Hemp extract containing multiple cannabinoids and terpenes but refined to remove detectable THC. Verify with the COA.
  • Full-spectrum: Hemp extract that includes trace THC within legal hemp limits; typically not considered THC-free.
  • Hemp (U.S. federal): Cannabis with no more than 0.3% delta‑9 THC by dry weight. Local rules may vary.
  • COA (Certificate of Analysis): A third‑party lab report showing potency, purity, and safety results for a specific batch.
  • LOD (Limit of Detection): The smallest amount a lab method can detect as present.
  • LOQ (Limit of Quantitation): The smallest amount a lab method can measure and report with confidence. Results below LOQ may appear as “ND.”
  • ND (Non-detect): The analyte is below the method’s LOQ; it does not guarantee absolute zero.
  • Total THC: Often calculated as delta‑9 THC + (THCA × conversion factor). Some programs use “total THC” for compliance.
  • Potency vs. concentration: Potency commonly refers to mg of cannabinoid per serving or per container; concentration often refers to mg/mL or % by weight.
  • Serving size: The labeled amount per use (for example, 1 mL or 1 gummy). Follow the product label’s instructions.
  • Carrier oil: An oil (e.g., MCT, hemp seed oil) used to deliver CBD in tinctures.
  • Bioavailability: The proportion of CBD that enters circulation and can be used by the body; varies by format and individual factors.
  • Batch/Lot number: Identifier linking your product to its specific COA.

Lab report basics for THC-free shoppers

Reading a COA helps confirm whether a product meets your THC-free preference. Look for:

  • THC line items: Delta‑9 THC and Total THC should show ND or near-zero values relative to the LOQ.
  • LOQ context: ND means “below the lab’s LOQ,” not necessarily absolute zero.
  • Batch match: The COA’s batch/lot number should match your product’s label.
  • Date and lab: Recent testing from an accredited, independent lab is best practice.

For detailed definitions of every panel and abbreviation, see the COA Glossary.

Cannabinoids and terpenes at a glance

CBD is one of many cannabinoids found in hemp, and terpenes are aromatic compounds that contribute flavor and scent. Broad-spectrum products aim to retain a range of these compounds while removing detectable THC; isolates contain only CBD. For in‑depth terms and examples, visit the Cannabinoid Glossary and Terpene Glossary.

THC, testing, and drug screening

Workplace and athletic drug tests typically screen for THC metabolites, not CBD. While THC-free products are designed to minimize THC exposure, no product can guarantee a particular test outcome. Factors like trace levels, serving size, frequency of use, and individual metabolism may influence results. Manufacturing controls and third‑party testing help reduce risk.

For terminology around testing methods, cutoffs, and metabolite names, see the THC & Testing Glossary.

A–Z sampler of helpful terms

  • Certificate of Conformity (CoC): Statement that a product meets specified requirements; not a substitute for a COA.
  • Decarboxylation: Heating that converts cannabinoid acids (e.g., CBDA) into their neutral forms (e.g., CBD).
  • Distillate: Refined hemp extract containing concentrated cannabinoids; can be made into broad‑spectrum or isolate products.
  • Emulsion/Water‑soluble: Formulations that disperse cannabinoids in water-based products to aid consistency and absorption.
  • Entourage effect (theory): The idea that cannabinoids and terpenes may work better together than alone; evidence is still developing.
  • GMP/cGMP: Good Manufacturing Practice standards for consistent, quality-controlled production.
  • Microbials/Residual solvents/Heavy metals: Safety panels on a COA that screen for contaminants.
  • Matrix: The product type tested (e.g., oil, gummy). Results apply to that specific matrix and batch.
  • Trace THC: Very small amounts that may be present or below LOQ; “trace” is not the same as zero.
  • Tincture: A liquid CBD product intended to be taken by mouth (often with a dropper for measured servings).
  • Winterization: A process that removes fats and waxes from extracts to improve clarity and consistency.
  • Zero‑THC (marketing): Often used interchangeably with THC‑free; still confirm via COA and LOQ values.

FAQ

Is “THC-free” the same as 0.00% THC?

No. In practice, THC-free usually means THC is non-detectable (ND) relative to the lab’s LOQ. ND does not guarantee absolute zero.

What does ND mean on a COA?

Non-detect. The lab did not quantify the compound above its LOQ. Different labs may use different LOQs.

Will THC-free CBD show up on a drug test?

It’s unlikely to cause a positive result, but no product can promise outcomes. Factors include trace amounts, frequency of use, and individual metabolism.

Is CBD isolate better than broad-spectrum for avoiding THC?

Isolate products are typically the most straightforward for avoiding THC. Some broad-spectrum products also test ND for THC; always verify with the COA.

How do I verify a product is THC-free?

Match the batch number on your product to a third‑party COA, check delta‑9 and total THC values, and confirm ND relative to the LOQ.
