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.
“The idea that this is an evil drug is a very recent construction,” and the fact that it is illegal is a “historical anomaly,” Warf said. Marijuana has been legal in many regions of the world for most of its history.
Where did pot come from?
“Many early prejudices against marijuana were thinly veiled racist fears of its smokers, often promulgated by reactionary newspapers,” Warf wrote in his report. “Mexicans were frequently blamed for smoking marijuana, property crimes, seducing children and engaging in murderous sprees.”
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.
Cannabis came to the Middle East between 2000 B.C. and 1400 B.C., and it was probably used there by the Scythians, a nomadic Indo-European group. The Scythians also likely carried the drug into southeast Russia and Ukraine, as they occupied both territories for years, according to Warf’s report. Germanic tribes brought the drug into Germany, and marijuana went from there to Britain during the 5th century with the Anglo-Saxon invasions. [See map of marijuana’s spread throughout the world.]
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.
Americans laws never recognized the difference between Cannabis sativa L. and Cannabis sativa. The plant was first outlawed in Utah in 1915, and by 1931 it was illegal in 29 states, according to the report.
If you find a larger quantity of processed marijuana buds in your home, someone either has an expensive habit or they are selling weed to their friends.
Marijuana buds are higher in THC than other parts of the plant and are sold at a premium. As marijuana has been increasingly bred to produce more buds, you may find this type of marijuana in your home. It is probably much more potent than the average street-grade weed.

You may find a small amount of marijuana your child has acquired for personal use to smoke. It is probably readily available in your community.
Plastic Bag Full of Marijuana
If your child is using marijuana, you may be likely to find rolled joints of marijuana cigarettes. You may also find rolling papers. Your child may claim that these are hand-rolled tobacco cigarettes, which would also be a concern.
If you look closely at a marijuana bud, you will see the fine "hairs" and leaves that make up the bud after it is dried.
