It’s the single plant that can feed us, clothe us, house us, protect the environment and support human health. With more than 60,000 uses, hemp has the ability to support humankind on almost every level. So why is a plant that’s so multidimensional so misunderstood? Here is a look at the fascinating — and oftentimes rocky — history of hemp.
What is hemp?
Hemp is a variety of
L. known for its tall, stalky growth, durable fibers, and high levels of the cannabinoid known as
. Unlike its close relative
, hemp plants do not contain significant levels of the

Today, hemp is cultivated for use in many industries, including biomass to make textiles, seeds for oil and eating, and of course, CBD production. However, this was not always the case. Under recent federal legislation, hemp (defined as all parts of the plant
L. containing 0.3% THC or less) was confirmed to be excluded as a Schedule I substance from the U.S. Controlled Substances Act (CSA). This has opened up the hemp industry to domestic production and the expansion of hemp-based products in the U.S.
However, it wasn’t always that hemp was so tightly controlled and regulated. In fact, hemp has been part of human society for millenia and is widely celebrated for its seemingly endless array of uses.
The timeline of hemp in human civilization
Hemp has a rich history of use in human civilization, which dates back to 8,000 BC. Hemp has been a staple crop for so long because of its immense versatility and ease of cultivation. Let’s start from the beginning:
The first traces of hemp are found in Asia. Soon after, hemp is found in Europe, Africa and South America, with hemp seeds and oil used for pottery and food.
2000 BC-800 BC

Hemp becomes an excuse to search and deport Mexican immigrants. As a result, the word “marijuana” replaced “cannabis” as a way to directly associate the plant with the Mexican population.
Harry Anslinger, the first commissioner of the United State’s Federal Bureau of Narcotics, who was previously on record stating that cannabis use was “not a big deal,” changes his position when the ban on alcohol is lifted and tells the public that cannabis is a “devil drug” that “turned men into wild beasts that would attack women.” Anslinger contacts thirty scientists requesting evidence that cannabis is dangerous, and twenty-nine say they can’t find any valid proof. Only one expert agrees with him.
Many prominent American businessmen, including Anslinger, decide that cannabis, with no distinction between marijuana and hemp, poses a threat to their businesses. Anslinger joins forces with William Randolph Hearst, Andrew Mellon, and the DuPont family to draft the Marihuana Tax Act to begin taxing the plant. 1942
