What is International Hemp Day?

International Hemp Day is held every year on April 21 and is observed worldwide. The day celebrates the versatility of the hemp plant and its contribution to sustainability, agriculture, and innovation. Hemp is a variety of the cannabis plant grown specifically for industrial purposes and contains little or no THC. Its fibers, seeds, and oils are used in a wide range of products, including textiles, building materials, food, and cosmetics.

The purpose of International Hemp Day is to raise awareness about the environmental benefits of hemp and to encourage broader use across industries. In the Netherlands, the day is marked by sustainable brands, farmers, and advocacy groups who highlight hemp’s ecological value and economic potential.

History and Origin

The cultivation and use of hemp dates back thousands of years. It was first grown in ancient China, where it was used to make fabric, rope, paper, and even medicinal preparations. In Europe, hemp became a key crop during the Middle Ages, especially valued for ship sails and clothing. Over time, global regulations against cannabis also affected hemp, despite its non-psychoactive nature.

In the 1990s and 2000s, interest in industrial hemp grew again due to its environmental benefits. International Hemp Day emerged as a way to promote this renewed interest and to encourage better public understanding of the plant. The day helps to separate fact from stigma and to support hemp as a legitimate, valuable resource.

Why is International Hemp Day important?

International Hemp Day is important because it helps reintroduce a plant that offers real solutions to some of today’s ecological and industrial challenges. Hemp is biodegradable, requires little water, and grows quickly without the need for heavy pesticides. It can be used to make sustainable textiles, building materials, and packaging. By drawing attention to these applications, the day encourages investment in better alternatives.

It also plays a key role in shifting public perception. Hemp has long been misunderstood due to its relation to cannabis, yet it holds none of the psychoactive effects associated with marijuana. International Hemp Day provides space to clear up that confusion and to reframe the conversation around environmental and social impact. It empowers consumers, producers, and policymakers to look forward and choose greener paths.
