What is hemp

The hemp plant is noticeable for its many uses and its special legal status. Knowing what hemp is means looking at its past, how it grows, and the laws around it.

Definition of hemp

Hemp, or Cannabis sativa, is different from marijuana. It’s known for its many uses. People have grown hemp for its fibre since 2800 BCE in China. It spread across Europe in the Middle Ages. It became key in making things like ropes and textiles. Nowadays, we use it for eco-friendly plastics and biofuels too.

Legal distinction from marijuana

The law sees hemp and marijuana differently because of their effects when used. Even though they’re both from Cannabis sativa, hemp has very little THC. THC is what makes marijuana give a ‘high’. Ernest Small introduced this idea in his book titled “The Species Problem in Cannabis: Science & Semantics” in 1979. It’s crucial to laws like in the U.S. Agricultural Act of 2018. This act helps separate hemp from marijuana.

The 0.3 percent rule

Setting hemp apart legally means looking at its THC levels. The current rule is that hemp must have 0.3 percent THC or less. This rule makes sure hemp doesn’t make people high. It’s an important rule for hemp to be used legally. It’s why we can use hemp for fibres, seeds, and oils without worry. Farmers plant it close together to grow tall and with fewer branches.

History of hemp cultivation

The cultivation of hemp, also known as cannabis sativa, has a long history. It dates back to ancient times. It’s been key in many cultures, playing a big role in their everyday life and traditions.

Ancient uses of hemp

Ancient people found many uses for hemp. They first started using it to make fibre about 50,000 years ago. The early Chinese made paper from it around 150 BC. This shows how important hemp was for new inventions. In India, it helped make textiles, ropes, and even for healing.

The early Greeks used hemp to heal, and the Vikings used it for their ships’ ropes and sails.

Hemp in modern times

Hemp cultivation saw big steps forward during the Industrial Revolution. European countries, with France in the lead, began producing lots of hemp. They used it to make textiles, paper, and even building materials, boosting their economies.

Nowadays, laws around growing hemp have changed, mainly in North America and Europe. This has led to more hemp being grown for many different uses. People make biofuels, bioplastics, and eco-friendly construction materials from it.

The story of hemp isn’t just in the past. It’s making a comeback today. People are again seeing its value for industry and farming in ways that are good for the planet.

EraPrimary uses of hemp
Ancient timesFibres, textiles, ropes, paper, medicinal uses
Early industrial eraTextiles, paper, ropes
Modern timesBiofuels, bioplastics, construction materials, textiles

Cannabis sativa’s story has always been full of change and progress. From old times to now, its uses in industry have grown a lot. Its future looks just as exciting as its past was.

Hemp plant characteristics

Getting to know the botanical features of hemp helps us understand its many uses. Hemp has a long history, going back to 2800 BCE in China for its fibre. It can grow up to 5 meters tall in cooler areas, showing its strength and ability to thrive.

Botanical features

Hemp is known for its tall stalks that yield strong fibres. These fibres are longer and less flexible than those from flax, often over 1.8 meters long. This makes hemp perfect for making clothes and other materials.

Its seeds are also very valuable, with about 30% of them being oil. They are high in protein, fibre, and key minerals like magnesium. They’re known as hemp hearts and are popular in healthy foods, and added to salads or smoothies.

Differences from marijuana plants

Hemp and marijuana come from the same plant, Cannabis sativa, but they are quite different. The key is in the debate of hemp vs. marijuana and their uses. Hemp is grown for fibre and seeds, often very close together to grow taller for better fibre. Marijuana, on the other hand, is spaced out to grow its potent flowers.

Another big difference is in what they contain. Hemp has tiny amounts of THC, the part that makes you high, in contrast to marijuana. That’s why hemp won’t make you high, but some marijuana can.

The benefits of hemp

Hemp has many advantages for us and the world. It has a big positive effect on the environment. Also, it’s very nutritious and has medical uses, especially through hemp-derived CBD. More and more people are seeing these benefits, which is why hemp is becoming popular again.

The United States

The 2018 Farm Bill changed the game for hemp in the US by allowing its growth. It says hemp must have 0.3% THC or less by weight to be legal. This makes CBD products from hemp okay nationwide, but states can add their own rules. It opened big doors for the hemp business, offering clear legal steps for those involved.


In Europe, hemp farming is part of a carefully managed system tied to the EU’s rules. Each country may have its own way of doing things, but if hemp has over 0.2% THC, it’s not allowed. Places like France, the Netherlands, and Germany are big in Europe’s hemp scene. The area aims for sustainable ways of growing hemp, helping it boom as a key crop again.


Asia handles hemp laws in various ways. China, for example, has been growing hemp for thousands of years and still finds it very useful. But places like Japan and South Korea have very strict rules. They’re starting to ease these rules. In India, there’s interest in changing laws to get economic benefits from hemp. This mix across Asia shows a blend of old traditions and new rules.

Challenges in hemp cultivation

Growing hemp is full of hurdles that need careful handling to get a good harvest. You must deal with both rules and how to grow the plant well. It’s not easy but worth it.

Regulatory hurdles

Rules about growing hemp differ a lot from place to place. This makes it hard for farmers because they need to know local and even global laws. Even though the US made hemp legal in 2018, each state has its own rules. This can slow down a farmer’s growth.
