Ancient Hemp: The First Cultivated Crop

Cannabis sativa L. is one of humanity's oldest cultivated crops. Archaeological evidence places hemp cultivation in Europe as early as 5,500 BCE, with hemp fibre imprints found on pottery from the Linear Pottery culture in modern-day Germany. By the Bronze Age, hemp was widely cultivated across Europe for cordage, textiles, and sailcloth.

The plant's utility made it strategically important. Hemp fibre produced stronger, more rot-resistant rope and sailcloth than any alternative available before synthetic materials. The Age of Sail — from the 15th through 19th centuries — was powered by hemp. A single first-rate Royal Navy ship of the line required over 80 tonnes of hemp fibre for its rigging and sails. European maritime powers including Britain, France, Spain, and the Netherlands all mandated or heavily subsidised domestic hemp cultivation as a matter of national security.

Hemp was also essential for paper production. The Gutenberg Bible, the first major book printed with movable metal type in Europe around 1455, was printed on hemp paper. The United States Declaration of Independence was drafted on hemp paper. Until the mid-19th century, when wood-pulp paper production became commercially viable, hemp and flax rags were the primary raw materials for European papermaking.

The 20th Century: Prohibition and Its Consequences

The prohibition of cannabis in the 20th century was driven by complex political, racial, and economic forces. The 1925 Geneva Opium Convention, organised by the League of Nations, was the first international treaty to impose controls on cannabis. Egypt, backed by Italy and the United States, successfully pushed for the inclusion of cannabis in the convention, arguing that its use caused insanity and violence — claims rooted in colonial-era prejudice rather than scientific evidence.

The United States Marihuana Tax Act of 1937 effectively criminalised cannabis cultivation nationwide, and the subsequent 1961 UN Single Convention on Narcotic Drugs classified cannabis and cannabis resin under the strictest control schedules, alongside heroin and cocaine. Throughout this period, the distinction between industrial hemp (low-THC Cannabis sativa cultivars grown for fibre and seed) and drug-type cannabis (high-THC cultivars grown for psychoactive use) was largely erased. Most countries either banned hemp cultivation outright or imposed licensing requirements so stringent as to be effectively prohibitive.

Europe was not immune. While countries like France and Spain maintained small-scale hemp fibre production through World War II (when blockades cut off imported fibres), most European nations severely restricted or banned hemp cultivation in the post-war decades. By the 1970s, the ancient European hemp tradition had been reduced to a few isolated regions — notably in France, where hemp fibre production for specialty paper and textiles persisted at a small scale.

The European Regulatory Renaissance (1990s–Present)

The modern era of European hemp began in the 1990s, driven by agricultural diversification policies and the rediscovery of hemp's environmental benefits. The EU's Common Agricultural Policy reforms of the 1990s allowed member states to subsidise hemp cultivation as an arable crop, subject to THC limits. Early adopter countries — notably France, Germany, the Netherlands, and the United Kingdom — established licensed hemp cultivation programmes.

Key regulatory milestones include: Regulation (EEC) 1308/70, which first established the EU framework for hemp subsidies; Regulation (EC) 1251/1999, which set the THC limit at 0.2% for eligible hemp varieties; Regulation (EU) 1308/2013, which maintained the 0.2% limit; and Regulation (EU) 2021/2115, which raised the limit to 0.3% effective 2023 while allowing stricter national limits. The 2019 European Commission determination that CBD extracts are novel foods — requiring pre-market safety authorisation — created the regulatory framework within which the current CBD market operates.

The 2020 Kanavape ruling by the Court of Justice of the European Union (Case C-663/18) was the single most important legal development for the CBD industry. The ruling established that CBD is not a narcotic, that member states cannot prohibit the marketing of CBD lawfully produced in another member state, and that the free movement of goods applies to CBD products. This ruling has been called the Magna Carta of the European CBD industry.

The Czech Hemp Tradition and Heffernan's Hemp

The Czech Republic has a distinctive place in European hemp history. The region — Bohemia and Moravia — was a significant hemp-growing area in the Austro-Hungarian Empire, producing fibre for textiles, cordage, and paper. While hemp cultivation declined in the communist era, the post-1989 period saw a rapid revival, driven by both agricultural entrepreneurship and a relatively permissive regulatory environment.

Today, the Czech Republic is one of Europe's most CBD-friendly markets, with a well-established domestic hemp industry supporting both outdoor and indoor cultivation. Heffernan's Hemp operates an indoor cultivation facility in the Czech Republic, where temperature, humidity, photoperiod, and soil biology are precisely controlled to optimise cannabinoid and terpene expression. This controlled environment produces consistent, pharmaceutical-grade biomass harvest after harvest — a fundamentally different approach from outdoor mass-market hemp farming.

Our choice of the Czech Republic as our cultivation base is deliberate. The country combines a centuries-deep hemp tradition, a supportive regulatory environment, and the technical expertise required for the kind of quality-controlled indoor cultivation that produces superior full-spectrum extracts. Every bottle of Heffernan's Hemp CBD oil is a product of that tradition and that commitment.

How long has hemp been cultivated in Europe?

Archaeological evidence places hemp cultivation in Europe at least 7,500 years ago (5500 BCE), with hemp fibre imprints found on Neolithic pottery in modern-day Germany. Hemp has been continuously cultivated in Europe for millennia.

Why was hemp banned in the 20th century?

Hemp prohibition was driven by political forces that conflated industrial hemp with drug-type cannabis. The 1961 UN Single Convention classified all cannabis under strict controls, and most countries banned hemp cultivation outright or imposed prohibitive licensing requirements throughout the mid-20th century.

When did hemp cultivation return to Europe?

The modern European hemp renaissance began in the 1990s, driven by EU agricultural policy reforms. France, Germany, the Netherlands, and the UK were early adopters. The EU now permits hemp cultivation for varieties with ≤0.3% THC (2023+), with an eligible variety catalogue.
