Overview
Hemp was not merely tolerated in colonial America — it was required. The Virginia Assembly passed legislation in 1619 ordering every farmer to grow hemp, and similar mandates followed in Massachusetts and Connecticut. The British Crown demanded hemp production from its colonies to supply the Royal Navy with rope and sail canvas, making it a strategically vital crop.
George Washington grew hemp at Mount Vernon and documented his cultivation practices in detailed diary entries. Thomas Jefferson grew hemp at Monticello, and the Declaration of Independence was drafted on hemp paper. Benjamin Franklin owned a hemp paper mill. These founding fathers viewed hemp as essential to American agricultural independence.
Hemp remained a major American crop through the 19th century, with Kentucky becoming the nation's leading producer. The crop was used for rope, textiles, paper, and lamp oil. It was not until the early 20th century that hemp's association with marijuana would lead to its decline as a mainstream agricultural commodity.
01
The Jamestown colony established hemp as a foundational American crop in 1611, just four years after its founding. By 1619, the Virginia Assembly had made hemp cultivation compulsory, requiring every settler to grow a minimum number of plants. The law reflected hemp's strategic importance: the Royal Navy consumed enormous quantities of hemp rope and canvas, and Britain's colonies were expected to supply this critical material.
02
Colonial hemp mandates spread rapidly. Connecticut and Massachusetts enacted similar requirements in the 1630s, and Maryland followed in 1639. Hemp could even be used to pay taxes in Virginia, Pennsylvania, and Maryland — a testament to its value as a commodity. These policies established hemp as one of the most widely cultivated crops in early American agriculture, alongside tobacco and cotton.
03
George Washington's diaries contain numerous references to hemp cultivation at Mount Vernon between 1765 and 1795. He experimented with different planting techniques and expressed particular interest in the quality of hemp fiber. In a famous 1794 diary entry, Washington wrote about separating male from female plants, which some historians interpret as interest in the plant's medicinal or psychoactive properties, though this remains debated.
04
Thomas Jefferson championed hemp as a rotation crop and even invented an improved hemp brake for processing the plant's fibers. He grew hemp at his Monticello plantation and, while serving as Ambassador to France, allegedly smuggled high-quality hemp seeds from China back to America — risking severe penalties — because he believed the Chinese varieties produced superior fiber.
05
Kentucky emerged as the hemp capital of America during the 19th century. By 1850, the state was producing 40,000 tons of hemp annually, primarily for rope and bagging used in the cotton industry. Hemp plantations, like cotton plantations, relied heavily on enslaved labor. The industry thrived until the Civil War disrupted Southern agriculture and cheaper imported fibers began to erode hemp's market position.
06
The decline of American hemp farming accelerated in the late 1800s as steam-powered ships reduced demand for hemp rope and canvas. Imported jute and manila hemp from Asia undercut domestic producers on price. By the early 20th century, hemp was a niche crop — making it vulnerable to the prohibitionist campaigns that would soon target all forms of cannabis.

Historical Significance
Hemp was a mandatory crop in colonial America and a cornerstone of early American agriculture and industry, grown by founding fathers and used for rope, paper, and textiles that built the new nation.
Frequently Asked Questions
Did George Washington grow cannabis?
Yes, George Washington grew hemp at Mount Vernon from at least 1765 to 1795. His diaries document planting schedules, fiber processing, and experimentation with cultivation techniques. Hemp was a common and legal agricultural crop during this period.
Was hemp really mandatory in colonial America?
Yes. Virginia passed a law in 1619 requiring all farmers to grow hemp. Connecticut and Massachusetts enacted similar mandates in the 1630s. Hemp could even be used to pay taxes in several colonies due to its strategic and economic importance.
What was hemp used for in early America?
Colonial hemp was used primarily for rope, sail canvas, textiles, paper, and lamp oil. It was a strategic military material essential for naval operations. The first two drafts of the Declaration of Independence were written on hemp paper.
Why did American hemp farming decline?
Hemp farming declined due to the shift from sailing ships to steam power (reducing rope demand), competition from cheaper imported fibers like jute, the disruption of Southern agriculture after the Civil War, and ultimately the prohibition of cannabis in the 20th century.
