  • The growing acceptance and regulation of cannabis worldwide have led to the expansion of both hemp and marijuana industries in various markets.

Historical Context and Legal Framework

Legal Milestones and the 2018 Farm Bill

The legal history of hemp and marijuana in the United States has been shaped by a series of milestone events. One of the earliest was the Marihuana Tax Act of 1937, which imposed restrictive tax measures on the cannabis industry. This act marked the beginning of the prohibition era for cannabis, including both hemp and marijuana.

In 1970, the Controlled Substances Act (CSA) was enacted, classifying marijuana and its derivatives as Schedule I controlled substances. Schedule I substances are considered to have a high potential for abuse and no accepted medical use. Hemp, although genetically distinct from marijuana, was also grouped under the CSA due to its association with the cannabis plant.

The 2018 Farm Bill, formally known as the Agriculture Improvement Act of 2018, brought about a significant change in the legal status of hemp. Under the Act, hemp was defined as cannabis containing 0.3% or less tetrahydrocannabinol (THC) by dry weight, effectively removing it from the CSA. This reclassification allowed for the cultivation, processing, and sale of industrial hemp under federal law.

From Prohibition to Legalization Trends

The legal landscape of cannabis has evolved over the past several decades, with an increasing number of states moving toward the loosening of restrictions on both hemp and marijuana.

The 1990s marked the beginning of a trend toward medical cannabis legalization, with California becoming the first state to legalize marijuana for medical use in 1996. Since then, a growing number of states have followed suit, allowing access to medical marijuana for qualifying patients.

In recent years, the push for recreational marijuana legalization has also gained momentum. Adult-use recreational marijuana is now legal in a significant number of states, with others actively considering legislation or ballot measures to achieve the same.

Parallel to these shifts in marijuana legislation, the hemp industry has experienced a resurgence following the passage of the 2018 Farm Bill. This has opened the door for a wide range of commercial applications for industrial hemp, from textiles and construction materials to food and health products, leading to an increasing interest in hemp cultivation and processing throughout the United States.

Botanical Distinctions

Species Differentiation

Both hemp and marijuana belong to the same species of plant, Cannabis sativa. However, they are distinct varieties with differing chemical compositions and uses. The primary differentiation between hemp and marijuana lies in the concentration of the psychoactive compound THC. Hemp typically contains less than 0.3% THC by dry weight, whereas marijuana contains a more significant amount of THC, ranging from 5% to 30% or more1.

Comparing Physical Characteristics

When examining the leaves, flowers, and seeds of hemp and marijuana, some notable distinctions can be observed:

  • Leaves: Hemp plants typically have skinnier leaves with more spacing between the leaflets. In contrast, marijuana plants generally have broader leaves with a denser arrangement2.
  • Flowers: Hemp plants produce smaller, scattered flowers, while marijuana plants grow larger, denser flowers that are often found in clusters2.
  • Seeds: Both hemp and marijuana plants produce seeds, but the seeds produced by hemp plants are typically larger and more viable for industrial and nutritional purposes3.

The physical differences in the appearance of hemp and marijuana plants are essential not only for plant identification but also for their contrasting applications. Hemp is grown primarily for its long stalks, which are rich in fibers suitable for industrial purposes such as textiles and rope4, while marijuana is cultivated for its flowers and leaves, which are the primary sources of THC and other psychoactive compounds5.

Chemical Composition and Uses

THC vs. CBD: Understanding Cannabinoids

The main distinction between hemp and marijuana lies in their chemical compositions, particularly the concentration of tetrahydrocannabinol (THC) and cannabidiol (CBD), which are both cannabinoids found in the cannabis plant. THC is a psychoactive compound that produces the ‘high’ associated with marijuana use, while CBD is non-psychoactive and is known for its potential health benefits.

Hemp 0.3% or less by dry weight High concentration
Marijuana 25% or more by dry weight Lower concentration

Hemp plants typically contain 0.3% or less THC by dry weight, allowing them to be legally classified as such in many countries and states. In contrast, marijuana plants usually have a higher THC concentration of 25% or more, making them the preferred choice for recreational and medicinal cannabis users seeking psychoactive effects.

Industrial and Medicinal Applications

Hemp: As a versatile plant with a long history of industrial use, hemp offers a wide variety of applications. Some popular uses for hemp include:

  • Production of strong fibers for making rope, clothing, and textiles

  • Hemp seeds as a nutritional food source rich in protein, healthy fats, and essential nutrients

Marijuana: The medicinal and therapeutic benefits of marijuana stem from its cannabinoids, particularly THC and CBD. Some of the medical uses for these compounds include:

  • Pain management for conditions like arthritis, migraines, and muscle spasms
  • Alleviation of anxiety, depression, and PTSD symptoms
  • Reduction of inflammation and promotion of overall well-being

Marijuana-derived products can come in various forms, including full spectrum oils, tinctures, edibles, and topical creams. In recent years, other cannabinoids like CBG have also gained attention for their potential therapeutic benefits, opening up new avenues for research and medical applications.
