The Jirzankal cannabis features higher levels of mind-altering compounds than have yet been found at any ancient site, suggesting that people could have been intentionally cultivating certain strains of cannabis for a potent high, or selecting wild plants known to produce that effect.
Wild strains of cannabis growing at higher altitudes, for instance, can have a higher THC content. Robert Spengler , director of paleoethnobotany laboratories at the Max Planck Institute for the Science of Human History and study co-author, says that the constant stream of people moving across the Pamir Plateau—an important crossroads connecting Central Asia and China with southwest Asia—could have resulted in the hybridization of local cannabis strains with those from other areas.
According to Spengler, this new study demonstrates that already 2, years ago, humans were potentially targeting specific plants for their chemical production.
The discovery at Jirzankal also provides the first direct evidence that humans inhaled combusted cannabis plants in order to obtain its psychoactive effects. No evidence of smoking pipes or similar apparatus has been found in Asia before contact with the New World in the modern era, but the inhalation of cannabis smoke from a heat source is described by the fifth-century B. The Scythians howl in their joy at the vapor-bath.
Mark Merlin , an ethnobotanist and cannabis historian at the University of Hawaii at Manoa, says the wide diversity in cannabis around the world today is a testament to how long people have been involved with the plant and harnessed its many uses.

We established a similar evolutionary symbiosis with an animal species, the canids, which also helped us to colonize the planet.
The dispersal of cannabis over Eurasia from a central point is reflected by the fact that the plant is designated by related words in most languages of this huge landmass. Reflecting the long association of cannabis and humans, some myths in India have cannabis emerge, as a divine ingredient, in the earliest stages of cosmogony, known as the churning of the ocean. Under names such as Vijaya , cannabis has been used for thousands of years in ayurvedic medicine to reduce pain, nausea, and anxiety, improve appetite and sleep, relax muscles, and produce a feeling of euphoria.
The global dissemination of cannabis came to a finale when the plant reached Africa, and ultimately America.
China can boast some of the earliest records of the medicinal use of cannabis. Because of him, it has been claimed that the discovery of medicinal cannabis dates back to two millennia bc. This character has the same meaning and usage in Japanese.
The topical application of cannabis for inflammation is mentioned in the Ebers papyrus, written in Egypt in about bc. The medicinal use of cannabis has been reported on Assyrian clay tablets. Herodotus c.
Herodotus remarks that hemp either grows spontaneously or is sown and cultivated by the Scythians. Only the latter discussed the psychoactive effects. The Naturalis Historia by Pliny the Elder c ad , the oldest extant encyclopedia from the Graeco-Roman world, is an exhaustive compilation of the knowledge available at the time. In Book 20, Pliny discussed the medicinal uses of cannabis, differentiating cultivated cannabis and a wild variety growing in forests probably, Althaea cannabina , a different plant.
Pliny indicated antalgic and anti-inflammatory properties: a decoction of the roots in water relieves arthritis and cures gout and similar maladies radix articulos contractos emollit in aqua cocta, item podagras et similes impetus. Pliny did not mention the intoxicating or euphoriant properties. The Greek physician Dioscorides c. As cited by Brunner, 14 Galen remarked that the seeds create a feeling of warmth, and if consumed in large amounts, affect the head by emitting a warm and toxic vapor.
Periods of tolerance already alternated visibly with periods of repression; for example, in , an emir decided that the teeth of those who consumed hashish would be extracted. Moreau quoted the report of Louis Aubert-Roche on the use of hashish to treat the plague in Egypt.
Moreau noticed that hashish produced pure bliss, but also disorganization of ideas and temporal distortions. He hoped that studying the effects of cannabis on the mind would help him to elucidate the mechanisms of madness and delusions. Moreau wrote about the psychoses and abulia induced by cannabis. Cannabis became persona grata in Western medicine in the late 19th, early 20 th century.
Queen Victoria took cannabis for painful menses, and Empress Elisabeth Sissi of Austria took it for cough, and possibly also to stimulate the appetite. Sissi was generally wary of medicines and appreciated that cannabis was a natural remedy. In several medical indications, cannabis was displaced by the discovery of other sedative and analgesic drugs such as aspirin. Throughout the 20 th century, a series of obstacles restricted the use of cannabis, particularly in the United States.
These successive measures were the Marihuana Tax Act in ; the removal of cannabis from the American pharmacopeia a few years later; and the United Nations Single Convention on Narcotic Drugs that placed cannabis under the strictest control regime Schedule IV along with heroin.
The Golden Age of cannabis came to a definite end in when it was declared a Schedule 1 drug in the USA, and research into the effects of cannabis was practically made impossible. Psychiatrists had additional reasons to be wary of cannabis when a year follow-up in a cohort of 45 Swedish conscripts established that cannabis is an independent risk factor for schizophrenia.
CBD was first isolated from marijuana in , and its structure was reported in The structure of the main psychoactive phytocannabinoid, THC, was determined in Israel by Mechoulam and Gaoni in He managed to obtain 5 kg of seized cannabis from the police, separated several compounds on a column, and identified one of these compounds as psychoactive by testing it on monkeys. Subsequently, Devane et al characterized a first cannabinoid receptor CB 1 R in rat and human brains. The long association of humans with cannabis made sense now that it was shown that our brain produced its own cannabinoid, although anandamide is entirely different from cannabis by its chemical class.
Today, the ECS is understood as comprising a few known endocannabinoids principally, AEA and 2-arachidonoylglycerol [2-AG] , and the two primary cannabinoid receptors CB 1 R, present mainly in the central nervous system, and also in digestive organs, and CB 2 R, implicated in the regulation of immunity and inflammation.
AEA and 2-AG are produced in the postsynaptic neuron and released into the synaptic space, then travel in a retrograde direction to the presynaptic terminal to interact with CB 1 Rs, which leads to a decrease in neurotransmitter release by the presynaptic neuron. An ancient Greek historian named Herodotus described the Scythians—a large group of Iranian nomads in Central Asia—inhaling the smoke from smoldering cannabis seeds and flowers to get high.
Hashish a purified form of cannabis smoked with a pipe was widely used throughout the Middle East and parts of Asia after about AD. Its rise in popularity corresponded with the spread of Islam in the region. The Quran forbid the use of alcohol and some other intoxicating substances, but did not specifically prohibit cannabis. Immigrants from Mexico to the United States during the tumultuous years of the Mexican Revolution introduced the recreational practice of smoking marijuana to American culture.
The Marijuana Tax Act of was the first federal U. The Act imposed an excise tax on the sale, possession or transfer of all hemp products, effectively criminalizing all but industrial uses of the plant. Fifty-eight-year-old farmer Samuel Caldwell was the first person prosecuted under the Act.
Caldwell was sentenced to four years of hard labor. Industrial hemp continued to be grown in the United States throughout World War II , when its domestic cultivation was encouraged after the Philippines—a major source of imported hemp fiber—fell to Japanese forces. The last U. It was identified in anti-drug programs like D. California , in the Compassionate Use Act of , became the first state to legalize marijuana for medicinal use by people with severe or chronic illnesses.
Washington , D. As of June , eleven states and Washington, D. Colorado and Washington became the first states to do so in Cannabis is still illegal under U.
As a young person, I remember being taught by my parents that the only person who could guide me was a woman who would not commit any crime, but what can her parents provide for us is love, attention, friendship and respect from their child?
While increased awareness about the potential impacts of marijuana use has emerged over the years, the increasingly popular culture and the films that cater to the seemingly irrepressible desire to binge have not diminished the overarching difficulties associated with cannabis use.
The pot was presented as an entryway to more dangerous drugs. President Theodore Roosevelt made a law in that the name of the drug and the amount contained in the bottle must be written on each container that contains the drug, and the Washington City Council implemented this law. Over the past year, public outrage has grown in the US due to the new laws. Following the Mexican Revolution, which saw almost one million Mexican immigrants venture to the United States, [16] there was a substantial decrease in public use of marijuana, which was charged to anti-Mexican sentiments, which supported the notion that Mexicans were highly accustomed to using cannabis recreationally.
A further consequence of the economic depression was that immigrants became jobless [17] , and the situation became further aggravated as they competed for employment. As a result of the Marijuana act [19] , domestic possession or transfer was made illegal in the United States, except if the possession or trafficking was for either medical or industrial purposes.
The National Narcotics Control Board, led by Harry Anslinger [20] , led by a movement against cannabis after discovering that there were high amounts of morphine and other psychoactive substances.
The government immediately broke this law, which was seen as an immediate drop in marijuana use in the United States. The primary aim of these acts was to curb marijuana abuse.
There are certain sentences associated with marijuana-related offences and other related drugs [23] that have been mandated to those convicted of these offences. At the beginning of the 20th century, there was an explosion in the use of marijuana for recreational purposes [26]. This can be traced to a boom in marijuana use between and During the same period, many thought L. Several years before the Comprehensive Drug Abuse Prevention and Control Act of was passed, President Lyndon Johnson signed the law that reduced the penalties for possessing cannabis.
That same year, a law was passed ruling marijuana did not assist with vaccinations and could be dangerous if abused. According to information gathered by President Richard Nixon in , on September 22, , the United States declared war on drugs, declaring that drug use was against the law and was thereby used against the country. As early as , the Drug Enforcement Administration D.
During the Cold War, his state passed the law against marijuana, and cocaine became one of the most abused drugs nationally [31] , which led to the emergence of anti-drug sentiments. However, these anti-drug programs were often ineffective and often moved youths to use drugs instead. AIDS was also spreading like wildfire all around the world during this period. The same benefits could also be extended to cancer patients on chemotherapy.
In , D. Francis Young held a hearing into the possibility of moving marijuana into Schedule II, limiting limited medical use. He concluded: [35]. Still, they are also discovering that medical marijuana is effective and safe, and a significant number of patients suffering from severe ill health have obtained their medical cannabis prescribes.
Several states joined California in [36] , and in the following years, five more joined it. As a result, a contest broke out between state and federal governments over marijuana. Were it is strictly forbidden on a federal level, would states be able to circumvent the federal law to enforce medical cannabis regulations for themselves? As a result, the Food and Drug Administration, the Department of Energy, and the National Institute on Drug Abuse exist to protect American consumers from the dangers posed by untested substances and keep them safe by regulating the legalization of new drugs.
Yet, many voters in Vermont believed that these groups were obstructing the legalization of marijuana.
