The history of cannabis and its use dates back further than the third millennium BCE in written history, based on archaeological evidence.
Cannabis is valued for its use for fibre and rope, as food and medicine, and for its psychoactive properties for religious and recreational use.
The earliest restrictions on cannabis were reported in the Islamic world by the 14th century. In the 19th century, it began to be restricted in colonial countries, and by the middle of the 20th century, international pressure led to restrictions on cannabis throughout most of the world.
The Netherlands became the first nation to legalize cannabis, and in 2015 Uruguay became the first to legalize recreational cannabis with Canada following in 2018. South Africa decriminalise it for personal home use only in 2020.
In 2012, archaeologists created reproductions of Easter Island’s statues, trying to figure out how ancient people may have moved the iconic 9,600-lb. (4.35 metric tons) heads from their quarry. Carl Lipo proved that all that was needed was hemp rope.
In 2011, researchers from the University of Saskatchewan announced that they’d discovered the genetic alteration that allows for the psychoactive properties that differentiate cannabis plants (Cannabis sativa)from non-psychoactive industrial Hemp.
In a 2014 study in the journal Drug and Alcohol Dependence, researchers found that females were more sensitive to cannabis’ painkilling qualities, but they were also more likely to develop a higher tolerance over time.
Since the legalisation of cannabis in many parts of the world, even medicinal pet products are flooding the market.
In 2012 a study done in Italy, researchers examined the air of Rome, Bologna, Florence, Milan, Naples, Palermo, Turin and Verona for psychotropic substances, including cocaine, marijuana, nicotine and caffeine. The scientists found all of these substances in all eight cities, with Turin having the highest total concentrations and Florence and Bologna having the highest concentrations of cannabis.
In 2016, researchers measured the levels of THC in more than 38,600 samples of street pot that had been seized by the FDA over a 20 year period. They found that the levels of THC rose from about 4 percent in 1995 to about 12 percent in 2014. THC levels were 14 times the level of cannabidiol in 1995; in 2014, that ratio had grown to 80.
The “bulkiest drug seizure” of marijuana ever was 2,903 metric tons, or 6.4 million pounds, that came from a Colombian drug operation.
It’s not possible to overdose on cannabis.
Like many other plants, marijuana can trigger allergic reactions in rare cases. The pollen and smoke can cause allergies in some people. Marijuana allergies are on the rise.
There is academic debate over how many people should be considered dependent on marijuana, but according to the National Institute on Drug Abuse of America, it can be measured at about 9 percent of users.
Marijuana compounds can inhibit certain liver enzymes called cytochrome P450 enzymes, meaning Viagra won’t break down as readily in the blood of someone who’s been smoking it.
In South Africa, America and many other places, cannabis was a common ingredient in medicinal tinctures, and sellers didn’t even have to mention it on their labels 100 years ago.
Approximately 2,700 years ago, a 45-year-old man died in Xinjiang, China. His bones were interred in a cemetery in the Gobi Desert, alongside his body, someone placed a bag and a bowl of 28 ounces (789 grams) of Cannabis sativa. Around the same time that the 45-year-old man died, another man in a neighbouring cemetery had a similar burial. In October 2016, researchers reported that they’d found the grave of a 35-year-old man who’d been laid to rest under a shroud of cannabis.
Cannabis And Hops Are In The Same Family – Both plants look similar, and have pungent aromas. Both plants also contain many of the same terpenes, hence the signature smell. There is now some research being done in it’s applications in the alcohol industry.
