Hemp was a major colonial crop β George Washington and Thomas Jefferson both grew it. Cannabis was widely used in patent medicines throughout the 1800s.
The Marihuana Tax Act of 1937 effectively banned cannabis, driven by racial prejudice and industrial interests. The counterculture of the 1960s brought mass recreational use, and the War on Drugs led to mass incarceration.
California's Proposition 215 in 1996 launched the modern medical cannabis movement. Colorado and Washington legalized recreational use in 2012, opening the floodgates for state-level reform.
The United States has the most diverse and advanced cannabis cultivation scene in the world. The Emerald Triangle β Humboldt, Mendocino, and Trinity counties β is the most famous cannabis-growing region on Earth.
Modern legal operations range from craft micro-cultivators to industrial-scale facilities spanning hundreds of thousands of square feet.
The US pioneered modern cannabis extraction. BHO, CO2 extraction, rosin pressing, live resin, diamonds, sauce β American extractors have pushed the boundaries of concentrate technology.
California and Colorado lead global innovation in extraction.
Cannabis remains federally illegal (Schedule I). As of 2025, 24 states have legalized recreational use and 38 have medical programs.
Federal reform β including the SAFE Banking Act and potential rescheduling β is ongoing.
