Marijuana History: The Cannabis Timeline

The history of cannabis in America has been fraught with criminal penalties, government-sanctioned production, and a whirlwind of other contradictory laws at the federal and state level.

First Mentions of Marijuana in History

The history of marijuana dates to the earliest human contact, around 12,000 years ago in central Asia. According to the history of weed, cannabis seeds were discovered in the remains of migrating nomadic peoples. Archaeologists have uncovered paraphernalia relating to marijuana dating to the first millennium BC throughout Assyria, Africa, India, and china.

The history of weed can be found throughout the medicinal cannabis records of China, Egypt, and Greece. Herodotus mentions the use of medicinal marijuana in Ancient Greece. Galen, Dioscorides, and Pliny the Elder mention the use of medical marijuana throughout Ancient Rome.

Throughout the 19th century, when Western Physicians came into contact with Indian and Muslim cultures, they found the use of medical marijuana widely practiced. Many Western Physicians brought cannabis back to Europe for medicinal use. But the history of cannabis in the United States can be broken down into the original agricultural account involving hemp and the introduction of recreational marijuana around the same time in the 19th century.

Cannabis was also used to improve sleep and improve cognition. In Indian culture, cannabis has many spiritual ties. Ancient Hindu scriptures state that the cannabis plant originated from a drop of heavenly nectar that fell to the sky. That drop led to the growth of the cannabis plant. Throughout the scriptures, cannabis was referred to as an anxiety treatment.

The History Of Marijuana In The US

The history of cannabis in the United States dates back to the Colonial era. It wasn’t used medicinally or for recreational purposes at this time, but it was still a government-sanctioned crop. Colonists regularly grew the cannabis plant for economic purposes.


  • The 1600s: The cannabis history timeline begins in the United States with the production of the cannabis plant or hemp plant encouraged by the government. Hemp was used for clothing manufacturing and the production of rope and sails for boats. Virginia passed a law in 1619 requiring every farmer in the Virginian Colony to grow hemp. It was so popular that hemp was a legitimate form of currency in Maryland, Pennsylvania, and Virginia.
  • The 1800s: The history of cannabis in America grows weaker after the Civil War for material products, but the marijuana timeline around the 19th century sees marijuana as a popular medicinal ingredient sold in pharmacies for medicinal purposes.
  • 1906: The Food and Drug Act required any cannabis-containing products to be labeled as such. At this stage in the history of cannabis, over-the-counter medicinal remedies were regularly sold.
  • 1910: The marijuana timeline gets another boost after the Mexican Revolution, where recreational marijuana was brought into the United States by Mexican immigrants. Around the same time, weed history facts show that anti-drug campaigns started popularizing discrimination and attempts to criminalize marijuana, then called the “Marijuana Menace.”

The History Of Marijuana In The US - Introduction


  • 1930: During the Great Depression, there was fear that unemployment and increased access to marijuana would result in a drug epidemic. So 29 states criminalized the use of the cannabis plant in any form. It was during this time that the Federal Bureau of Narcotics was created.
  • 1932: In 1932, the Federal Bureau of Narcotics encouraged state governments to take individual control over marijuana use in their territories through the Uniform State Narcotic Act.
  • 1936: “Reefer Madness” was a propaganda film that initiated a ban by the Motion Picture Association of America on any narcotics in Hollywood films.

  • The 1940s: The New York Academy of Medicine produced scientific reports concluding that marijuana was not addictive, nor did it induce violence or result in insanity. The US Department of Agriculture began to increase hemp production for military gear, parachutes, and cords. 375,000 acres of hemp were registered in the United States under the “Hemp for Victory” program.

President Nixon rejected the idea. However, 11 states began decriminalizing the use of state Marijuana while others reduced the severity of the penalties for cannabis use. It was in 1973 that the US Drug Enforcement Agency was created after merging the Office of Drug Abuse Law Enforcement and the Bureau of Narcotics and Dangerous Drugs.
