What Is Hemp? Differences Between Hemp & Cannabis

1. Understanding Hemp: A Brief Overview

Hemp is a variant of the Cannabis sativa plant known for its extremely low levels of tetrahydrocannabinol (THC), the compound largely associated with psychoactive effects. While hemp and cannabis both belong to the cannabis family, hemp’s negligible THC content sets it apart, making it suitable for a wide range of everyday and industrial uses.

‍

Because hemp does not induce the “high” typically associated with cannabis, it occupies a separate space in many legal and cultural contexts. This separation has allowed hemp to flourish as a source of strong fibres, nutrient-rich seeds, and, more recently, innovative materials like bioplastics. Hemp’s non-psychoactive nature also makes it appealing to consumers seeking plant-based products without legal or recreational cannabis implications.

‍

2. A Look Back: Hemp’s Historical Significance

One of the earliest known domesticated crops, hemp has appeared in records stretching back thousands of years. It features prominently in various civilisations:

‍

• Ancient Civilisations: Archaeological findings often point to China as a hub for early hemp use, where it provided fibres for textiles and rope. Its seeds and oil may also have been part of daily diets.
• Middle East and Europe: As hemp cultivation spread westward, its robust fibres were particularly prized for maritime applications. Ropes, sails, and nets required strength and durability—properties that hemp fibres delivered effectively.
• Industrial Revolution: Hemp’s significance in the textile industry persisted, though it was eventually overshadowed by other materials and crops. Still, it never completely disappeared; smaller-scale cultivation continued in many parts of the world.

‍

Historically, hemp has thrived under different cultural and societal conditions, reflecting its adaptability. Whether used to make sturdy paper in ancient China or to outfit seafaring ships in Europe, hemp’s universal appeal arises from its versatility and ease of processing.
