The History of Cannabis

The Long Game: A History of Cannabis from Ancient Remedy to Modern Industry

Cannabis has been a pillar of global trade and medicine for more than 5,000 years. Its journey—from ancient ritual and industrial necessity to modern industry—is one of the most complex regulatory stories in human history.

Ancient Roots and Early Medicinal Frameworks

By 2727 BCE, Emperor Shen Nung documented the plant, noting that it may support the management of malaria and rheumatism. While China pioneered the use of hemp fiber for textiles and paper, Indian Vedic texts (dating between 2000 and 1400 BCE) categorized bhang as a formal resource. Ayurvedic practitioners were among the first to integrate the plant into a standardized health framework, which may support those experiencing chronic pain and anxiety. By 500 BCE, nomadic Scythian tribes were utilizing controlled inhalation in ritualistic settings, marking an early milestone in human interaction with the plant’s psychoactive properties.

Hemp as the Engine of Exploration

During the Classical era, scholars like Dioscorides and Galen documented the plant’s application, suggesting it may support the reduction of inflammation and mood regulation. Later, during the Islamic Golden Age, medical scholars codified its use, noting it may support those experiencing epilepsy and nausea.

In the West, the plant’s primary value remained industrial. Throughout the Age of Discovery, hemp was the backbone of global naval logistics. Every major power relied on hemp-based rope and sails to power their fleets; it was the essential material of the maritime economy long before it was viewed through the lens of domestic intoxication.

The Pharmaceutical Boom and Political Erasure

The shift toward clinical integration peaked in 1839, when William O’Shaughnessy introduced cannabis into Western practice. For the next several decades, pharmaceutical tinctures were a staple of the American and European apothecary.

This progress hit a wall in the early 20th century. The 1937 Marijuana Tax Act effectively shuttered the domestic supply chain, fueled by a campaign of social hysteria. The 1936 film Reefer Madness became the face of a new era, trading evidence for fear-based propaganda. By the time the 1961 UN Single Convention on Narcotic Drugs codified this prohibition globally, and the 1970 Controlled Substances Act labeled cannabis a Schedule I substance, the plant’s history had been effectively removed from mainstream legal consciousness.

The Path to Modern Normalization

The tide began to turn in the 1970s. Oregon’s 1973 decriminalization effort was the first crack in the foundation, though the "War on Drugs" in the 1980s stalled momentum for nearly two decades.

The modern era of legalization arguably began with California’s 1996 Proposition 215. This was the first time a state framework challenged the federal narrative. The sector shifted in 2012, when Colorado and Washington moved beyond medical use to legalize adult-use markets, rebranding the plant as an engine for state tax revenue.

Current Global Realities

Canada’s national legalization in 2018 set a new standard for institutional market structures, and Germany’s 2024 decision to legalize adult-use signaled a pivot in the European Union.

As of 2025, 24 U.S. states have fully legalized adult-use cannabis, with another 14 maintaining medical-only programs. Despite this, the industry remains in a state of regulatory limbo. Federal rescheduling is the final barrier to interstate commerce and standardized banking. Today, the competitive edge lies in supply chain transparency, rigorous compliance, and the ability to navigate the gap between state-level retail success and federal stagnation.
