how was weed found

It is important to distinguish between the two familiar subspecies of the cannabis plant, Warf said. Cannabis sativa, known as marijuana, has psychoactive properties. The other plant is Cannabis sativa L. (The L was included in the name in honor of the botanist Carl Linnaeus.) This subspecies is known as hemp; it is a nonpsychoactive form of cannabis, and is used in manufacturing products such as oil, cloth and fuel. [11 Odd Facts About Marijuana]

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.

After this really long “trip” throughout the pre-modern and modern worlds, cannabis finally came to the United States at the beginning of the 20th century. It arrived in the southwest United States from Mexico, with immigrants fleeing that country during the Mexican Revolution of 1910-1911.

Cannabis plants are believed to have evolved on the steppes of Central Asia, specifically in the regions that are now Mongolia and southern Siberia, according to Warf. The history of cannabis use goes back as far as 12,000 years, which places the plant among humanity’s oldest cultivated crops, according to information in the book “Marihuana: The First Twelve Thousand Years” (Springer, 1980).

From the sites where prehistoric hunters and gatherers lived, to ancient China and Viking ships, cannabis has been used across the world for ages, and a new report presents the drug’s colorful history.

Then, it wouldn’t have taken long for it to spread throughout the northern hemisphere via the exchange routes of the early Silk Road.

The implication of this is that the people of Jirzankal either sought out cannabis plants with higher THC content, or they cultivated them. It’s impossible to know which, but it does seem probable that it’s deliberate either way.

“This is among the earliest chemical evidence of cannabis smoking.”

“I think this is a wonderful example of how closely intertwined humans are and have been with the world around them,” said archaeobotanist Robert Spengler of the Max Planck Institute for the Science of Human History.

But there was something else. The data indicated a higher concentration of THC than is usually found in wild plants.

Specifically, archaeologists have found traces of cannabinol, an oxidative metabolite of tetrahydrocannabinol (or THC) in incense burners recovered from the ancient Jirzankal Cemetery on the Pamir Plateau.

“To our excitement, we identified the biomarkers of cannabis and local chemicals related to the psychoactive properties of a plant,” archaeologist Yimin Yang of the University of Chinese Academy of Sciences said in a press conference.

With a variety of cannabis strains the potency of marijuana varies greatly. The highest concentration of cannabinoids is found in the flowers of the female marijuana plant. Marijuana is much more powerful today than it was 30 years ago. The average THC levels rose from less than 1 percent in the mid-1970’s to more than 6 percent in 2002 to 8.5 percent in 2008.

One of the first fiber plants to be cultivated, prior to the widespread use of cotton, hemp has been referenced to originate in Central Asia. In the Middle East and India hemp was largely used in religious settings; however it was also used as a natural medicine. Hemp later made its way to Europe where its use as a fiber was highly ideal in many countries. Eventually, hemp landed in the Americas where it was popular for rope, clothing and paper.

Hashish, also known as hash, is the most concentrated and potent form of cannabis containing high levels of THC. Hash is derived from the dried resin of the plants flowering tops and is compressed into a variety of forms such as balls, cakes or sticks. The Middle East, North Africa, Pakistan and Afghanistan are the main sources of hashish. Pieces of hash are broken off and placed in pipes (similar to marijuana) and smokes.

Cannabis Varieties

As cannabis strains are continually discovered and grown the potency changes as well. The differences in marijuana potency are what make various strains popular. One of the most potent early strains is sinsemillas, which is seedless marijuana from the inflorescences of the female cannabis plants. Other more current strains known for their potency include: Purple Haze, Early Girl, Big Bud and Hindu Kush.

Hash oil is the refined oily extract of the cannabis plant. Depending on the refining technique the oil can vary in color from amber to dark brown with an average THC of content of approximately 15 percent. The oil is usually mixed with tobacco or marijuana and smoked.

Cannabis sativa grows wild throughout many tropical and humid parts of the world. Its seeds have been used for animal feed, its fiber for hemp rope, and its oil as a vehicle for paint.

In a variety of vending machines it is common to find marijuana packed at maturity, marijuana candies, marijuana gum and sometimes marijuana cigarettes.
