Hemp’s long history
Hemp has been cultivated for thousands of years for rope, textiles, paper, and later for seed and oil. In the 20th century, U.S. policy treated all cannabis similarly, which sharply reduced hemp production.
High-level timeline (U.S.)
- Pre‑1900s: hemp used for cordage and textiles; a common industrial fiber crop in many regions.
- 1930s–1970s: increasing restrictions on cannabis culminate in broad federal prohibition frameworks.
- 2014: research/pilot programs expand state-level hemp cultivation under the U.S. Farm Bill’s pilot provisions.
- 2018: the Farm Bill removes hemp (as defined) from the federal controlled substances list and expands lawful cultivation under approved plans.
Key point
Policy shapes markets. Modern hemp supply chains (fiber processing, grain handling, cannabinoid extraction) grew rapidly once cultivation scaled, but they still depend on consistent testing, labeling, and consumer trust.
