A second psychoactive species of the plant, Cannabis indica, was identified by the French naturalist Jean-Baptiste Lamarck, and a third, uncommon one, Cannabis ruderalis, was named in 1924 by Russian botanist D.E. Janischevisky.

“It likely flourished in the nutrient-rich dump sites of prehistoric hunters and gatherers,” Warf wrote in his study.

Burned cannabis seeds have also been found in kurgan burial mounds in Siberia dating back to 3,000 B.C., and some of the tombs of noble people buried in Xinjiang region of China and Siberia around 2500 B.C. have included large quantities of mummified psychoactive marijuana.

In the report, author Barney Warf describes how cannabis use originated thousands of years ago in Asia, and has since found its way to many regions of the world, eventually spreading to the Americas and the United States.

Cannabis growth is made up of a series of stages that plants undergo during their lifecycle. Each stage during the cannabis cultivation process requires its own unique demands, including different levels of light, water, and nutrients.

People feeling the effects of marijuana are prone to what scientists call “divergent thinking,” the process of searching for solutions to a loosely defined question.

To conduct the study, Dr. Ren and his colleagues collected 82 samples, either seeds or leaves, from around the world. The samples included strains that had been selected for fiber production, and others from Europe and North America that were bred to produce high amounts of tetrahydrocannabinol (THC), the plant’s most mood-altering compound.

As hemp’s function as a global source for textiles, food and oilseed dried up in the 20th century, the use of cannabis as a recreational drug increased, the new study noted. But there are still “large gaps” in knowledge about its domestication history, it said, in large part because the plant is illegal in many countries.
