Hemp and Marijuana: Definitions

What is Hemp?

Hemp refers to the varieties of Cannabis sativa that contain 0.3% or less THC (tetrahydrocannabinol) by dry weight. This low THC level means that hemp does not produce a psychoactive effect or “high.” Hemp is cultivated for its industrial and nutritional uses, which range from clothing and paper to food products and biofuel.

What is Marijuana?

Marijuana is a term used for Cannabis plants (primarily Cannabis sativa and Cannabis indica) that have higher THC content, typically above 0.3%. This higher THC concentration is responsible for the psychoactive effects that make marijuana popular for both medicinal and recreational use.

Botanical Classification

The Cannabis Plant Family

Both hemp and marijuana belong to the Cannabis genus, which includes various species and subspecies. The primary species are Cannabis sativa, Cannabis indica, and Cannabis ruderalis. The distinction between hemp and marijuana is not based on these species but rather on their THC content and uses.

Differences in Species and Varieties

Hemp and marijuana can come from the same species, Cannabis sativa, but are cultivated differently to enhance certain characteristics. Hemp is bred to maximize fibre, seed, and CBD (cannabidiol) content, while marijuana is bred to increase THC levels for psychoactive effects.

Chemical Composition

Cannabinoids Explained

Cannabinoids are chemical compounds found in the Cannabis plant. The most well-known are THC and CBD. THC is psychoactive, while CBD is non-psychoactive and has been associated with various health benefits.

THC Content in Hemp

By definition, hemp contains 0.3% or less THC. This minimal amount ensures that hemp products do not produce a “high.”

THC Content in Marijuana

Marijuana contains higher levels of THC, usually between 5% and 30%, depending on the strain. This high THC content is what gives marijuana its psychoactive properties.

CBD in Hemp vs. Marijuana

Both hemp and marijuana can contain CBD, but hemp typically has higher concentrations. CBD is prized for its potential therapeutic effects, including anti-inflammatory, anti-anxiety, and seizure-reducing properties.

Legal Status

Hemp Legalization

In many parts of the world, including the United States, hemp has been legalized for industrial use. The 2018 Farm Bill in the U.S. legalized hemp, allowing it to be grown and sold as an agricultural commodity.

Marijuana Legalization

Marijuana’s legal status varies widely. Some countries and states have legalized it for medicinal use, recreational use, or both, while others still classify it as an illegal substance.

Differences in Regulations

Hemp and marijuana are subject to different regulations. Hemp’s legal framework focuses on its low THC content, whereas marijuana is heavily regulated due to its psychoactive effects.
