Cannabis has been intertwined with human civilization for thousands of years — as medicine, fiber, food, and sacrament. Its journey from ancient pharmacopeia to global prohibition and back to mainstream acceptance is one of the most remarkable stories in the history of any plant.
The earliest documented use of cannabis dates to 2700 BC in China, where Emperor Shen Nung's pharmacopoeia listed cannabis as a treatment for gout, rheumatism, malaria, and "absentmindedness." The Chinese used both hemp fiber for textiles and rope and cannabis flower for medicine.
In India, cannabis held sacred status. The Atharva Veda (c. 1500 BC) listed cannabis among five sacred plants and described it as a source of happiness and liberation. Bhang, a cannabis-infused milk drink, has been consumed in Hindu religious ceremonies for millennia and remains legal in India today.
The Egyptians used cannabis for inflammation and pain, as documented in the Ebers Papyrus (c. 1550 BC). The Scythians, a nomadic Central Asian people, inhaled cannabis vapor in enclosed tent ceremonies — a practice confirmed by archaeological discoveries of charred cannabis seeds in burial sites.
Hemp arrived in the Americas with European colonists. The Virginia Assembly passed legislation in 1619 requiring every farmer to grow hemp — it was that valuable for rope, sails, and clothing. George Washington grew hemp at Mount Vernon, and early drafts of the Declaration of Independence were written on hemp paper.
By the 1800s, cannabis extracts were widely available in American pharmacies. Companies like Eli Lilly, Parke-Davis, and Squibb sold cannabis tinctures for pain, nausea, and insomnia. It was listed in the U.S. Pharmacopeia from 1851 to 1942 as a recognized medicine.
The early 20th century brought a dramatic shift. Anti-cannabis sentiment grew, fueled by xenophobia (the drug was associated with Mexican immigrants and Black jazz musicians), yellow journalism, and industrial lobbying. The term "marihuana" was deliberately used to make the familiar plant sound foreign and dangerous.
The Marihuana Tax Act of 1937 effectively criminalized cannabis at the federal level by imposing prohibitive taxes and regulations on its sale. Harry Anslinger, head of the Federal Bureau of Narcotics, led a public campaign linking cannabis to violence, insanity, and moral decline — claims that were unsupported by scientific evidence.
Cannabis became a symbol of the 1960s counterculture movement. Usage surged among college students, artists, and anti-war activists. In response, the Nixon administration launched the War on Drugs in 1971, and the Controlled Substances Act of 1970 classified cannabis as Schedule I — the most restrictive category.
The 1980s brought mandatory minimum sentences and "Just Say No" campaigns under the Reagan administration. Cannabis arrests skyrocketed, disproportionately affecting communities of color despite similar usage rates across racial groups. By the 1990s, the U.S. was incarcerating more people for drug offenses than any other country in the world.
California's Compassionate Use Act of 1996 (Proposition 215) was the turning point. It made California the first state to legalize medical cannabis, allowing patients with serious illnesses to use cannabis with a doctor's recommendation. Other states followed: Oregon, Washington, and Maine passed medical cannabis laws in 1998.
The recreational legalization wave began in 2012 when Colorado and Washington became the first states to legalize adult-use cannabis through ballot initiatives. The dominoes fell rapidly: Alaska and Oregon in 2014, California and Massachusetts in 2016, Michigan and Illinois in the late 2010s, and a steady stream of states through the 2020s.
As of 2026, the majority of Americans live in states where cannabis is legal in some form. The industry generates billions in tax revenue, employs hundreds of thousands of people, and continues to grow. Federal reform discussions around rescheduling and banking access continue to advance.
The history of cannabis is ultimately a story about how societies grapple with science, culture, race, and politics. After nearly a century of prohibition, the plant is returning to its historical role as a mainstream part of human life.
