What Is THC? — Definition, Cannabinoid Context & UK Terminology

What Is THC?

THC, short for tetrahydrocannabinol, is a cannabinoid commonly referenced in cannabis-related education, chemistry discussions, and seed catalogue terminology.

This page provides a neutral, reference-grade definition of THC as a chemical term. It explains how the term is used in educational and catalogue contexts without offering instructions, advice, or guidance of any kind.

THC — Clear Definition

THC (tetrahydrocannabinol) is a naturally occurring cannabinoid associated with the cannabis plant. It is one of several cannabinoids referenced in scientific literature and consumer-facing terminology.

Within educational and catalogue language, THC is typically discussed as part of a broader cannabinoid profile rather than as an isolated or predictive measure.

Cannabinoid Context

THC belongs to a wider family of compounds known as cannabinoids. These compounds are often discussed collectively when describing cannabis chemistry.

  • Cannabinoids — a group of chemical compounds associated with cannabis.
  • CBD — another commonly referenced cannabinoid, often discussed alongside THC.
  • Cannabinoid profile — a descriptive term summarising reported cannabinoid emphasis.

For a structured overview of cannabinoid terminology, see the Cannabinoids & Chemistry Knowledge Index .

How the Term Is Used in Seed Catalogues

In seed catalogues, THC is commonly referenced in simplified banding language such as “high THC” or “medium THC.” These labels function as navigation and comparison tools rather than precise chemical measurements.

Reported THC emphasis may vary due to genetics, environmental factors, and reporting standards. Catalogue terminology should be understood descriptively rather than as a guarantee or outcome.

Related classification language is explained within the Seed Classification Knowledge Index .

In the United Kingdom, THC is referenced within legal and policy frameworks relating to controlled substances. Legal interpretation and enforcement depend on statute and context.

This page does not provide legal advice. Terminology-only explanations of policy language can be found in the UK Legal & Policy Terminology Knowledge Index .

  • CBD — a cannabinoid often referenced in CBD-forward catalogue categories.
  • Terpenes — aromatic compounds used in scent and flavour descriptions.
  • Cannabinoids — the broader compound family to which THC belongs.

These terms are organised and cross-referenced within the Master Knowledge Index .
