The Origins of Marijuana

Today, growers cultivate marijuana, also known as cannabis and hemp, on farms equipped with cutting-edge technology designed to help boost the potency of their crops. Long before growers began experimenting with strains to create hybrids, marijuana grew wild in Central Asia. You may still find it growing there, but before booking a plane ticket and hotel, remember it’s probably nothing like the hybrid strains you’re used to!

Experts say marijuana evolved 28 million years ago on the Tibetan Plateau. It’s tough to know exactly when people started using cannabis, but archaeologists can make a pretty good guess, thanks to research.

Early Marijuana Use

Early Marijuana Use

So, when was marijuana discovered? The first documented case of marijuana use dates back to 2,800 B.C. when it was listed in Emperor Shen Nung’s pharmacopeia. This compendium, titled Divine Husbandman’s Materia Medica, includes 365 medicines from plants, animals, and minerals.

You may see Shen Nung referred to as the father of Chinese medicine, and for good reason. He introduced the technique of acupuncture and taught people how to cultivate grains for food. He also tasted medical herbs to test them until one of those herbs killed him from a toxic overdose.

Archaeologists know people burned marijuana for rituals about 5,000 years ago but that it had very low levels of tetrahydrocannabinol (THC), so they are not likely to have used it for its mind-altering properties. Researchers found evidence of cannabis with higher THC levels in the Pamir Mountains of Western China. It’s thought that people started using cannabis recreationally about 2,500 years ago.
