The 6,000-Year History of Medical Cannabis
View the high resolution version of today’s graphic by clicking here.
Since the early 20th century, the use of cannabis for any purpose fell out of favor by both regulators and Western culture at large.
In the United States, a wave of regulations made access to cannabis more difficult starting from the late 1900s, ultimately culminating in the Marihuana Tax Act of 1937, which effectively made cannabis use a federal offense. Meanwhile, prohibition in Canada lasted for 85 years until being lifted by recent developments.
Interestingly, however, this recent period of 20th century opposition is actually just a small speck in the wider 6,000-year timeline of cannabis. After all, the plant has been widely regarded for its therapeutic potential for many millennia by different cultures around the world.
6,000 Years of Medical Cannabis
Today’s infographic comes to us from MedReleaf, and it focuses on the medical uses of cannabis discovered by many cultures over time. With uses dating back to Ancient empires such as Rome, Egypt, and China, it helps to put into perspective recent legal and cultural developments regarding cannabis on a broader historical scale.
4000 BC: Pan-p’o village
Cannabis was regarded among “five grains” in China, and was farmed as a major food crop.
2737 BC: Pen Ts’ao Ching
Earliest record of cannabis as a medicinal drug. At this time, Emperor Shen-Nung recognized its treatment properties for over 100 ailments such as gout, rheumatism, and malaria.
2000-1400 BC: Scythians
Nomadic Indo-European peoples used cannabis in steam baths, and also burned cannabis seeds in burial rituals.
2000-1000 BC: Atharva Vedas
Cannabis was described as a “source of happiness”, “joy-giver”, and “bringer of freedom” in these Hindu religious texts. At this time, cannabis was smoked at daily devotional services and religious rituals.
2000-1000 BC: Ayurvedic Medicine
Open religious use of cannabis allowed for exploration of medical benefits. During this period, it was used to treat a variety of ailments such as epilepsy, rabies, anxiety, and bronchitis.
1550 BC: Ebers Papyrus
Egyptian medical papyrus of medical knowledge notes that medical cannabis can treat inflammation.
1213 BC: Ramesses II
Cannabis pollen has been recovered from the mummy of Ramesses II, the Egyptian pharaoh who was mummified after his death in 1213 BC.
900 BC: Assyrians
Employed the psychotropic effects of cannabis for recreational and medical purposes.
450-200 BC: Greco-Roman use
Physician Dioscorides prescribed cannabis for toothaches and earaches. Greek doctor Claudius Galen noted it was widely consumed throughout the empire. Women of the Roman elite also used cannabis to alleviate labor pains.
207 AD: Hua T’o
First recorded physician to describe cannabis as an analgesic. He used a mixture of cannabis and wine to anesthetize patients before surgery.
1000 AD: Treats Epilepsy
Arabic scholars al-Mayusi and al-Badri regard cannabis as an effective treatment for epilepsy.
1025 AD: Avicenna
The medieval Persian medical writer publishes “Avicenna’s Canon of Medicine”, stating that cannabis is an effective treatment for gout, edema, infectious wounds, and severe headaches. His work was widely studied from the 13th to 19th centuries, having a lasting impact on Western medicine.
1300 AD: Arab traders
Arab traders bring cannabis from India to Eastern Africa, where it spreads inland. It is used to treat malaria, asthma, fever, and dysentery.
1500 AD: Spanish Conquest
The Spanish brought cannabis to the Americas, where it was used for more practical purposes like rope or clothes. However, years later, it would be used as a psychoactive and medicinal drug.
Napoleon brought cannabis back to France from Egypt, and it was investigated for its pain relieving and sedative qualities. At this time, cannabis would be used to treat tumors, cough, and jaundice.
1839: William O’Shaughnessy
Irish doctor William O’Shaughnessy introduced the therapeutic uses of cannabis to Western medicine. He concluded it had no negative medicinal effects, and the plant’s use in a pharmaceutical context would rapidly rise thereafter.
1900: Medical Cannabis
Medical cannabis was used to treat nausea, rheumatism, and labor pain. At this point in time, it is available over-the-counter in medications such as “Piso’s cure” and “One day cough cure”.
1914: Harrison Act
Drug use was declared a crime in the U.S., under the Harrison Narcotics Tax Act in 1914.
1937: Marihuana Tax Act
The Marihuana Tax Act banned the use and sales of cannabis in the United States.
1964: Discovery of THC
The molecular structure of THC, an active component of cannabis, was discovered and synthesized by Israeli chemist Dr. Raphael Mechoulam.
1970: Classified as Schedule 1 Drug
Cannabis became categorized as a Schedule 1 Drug in the U.S., which limited further research into the plant. It was listed as having “no accepted medical use”.
1988: CBD Receptors Discovered
The CBD1 and CBD2 cannabinoid receptors were discovered. Today, we know they are some of the most abundant neuroreceptors in the brain.
2000-2018: Medical cannabis legalization
Governments, such as those of Canada and various states, begin to legalize cannabis for medical purposes from licensed producers. Recreational legalization quickly starts to follow.
Which Asian Economies Have the Most Sustainable Trade Policies?
The Sustainable Trade Index ranks 19 Asian economies and the U.S. across three categories of trade sustainability.
Which Asian Economies Have the Most Sustainable Trade Policies?
To say that Asia has benefited from international trade is an understatement. By opening its economies to the rest of the world, the region has become a leading exporter in many of today’s most important industries.
Trade has also improved Asia’s quality of life, lifting over one billion people out of poverty since 1990. Without the proper controls, however, such rapid growth could have harmful effects on Asia’s environment and society.
In this infographic from The Hinrich Foundation, we break down the results of their 2020 Sustainable Trade Index (STI). Since 2016, this index has ranked 19 Asian economies and the U.S. across three categories of trade sustainability: economic, social, and environmental.
What Exactly is Sustainable Trade?
International trade is an important source of economic growth, enabling domestic businesses to expand, reach new customers, and gain exposure to foreign markets.
At the same time, countries that focus too heavily on exports put themselves at greater long-term risk. For example, an aggressive expansion into manufacturing is likely to impair the quality of a country’s air, while overdependence on a single product or sector can create an economy that is susceptible to demand shocks.
“The primary principle which underpins sustainable trade is balance. Trade cannot be pursued solely for economic gains, without considering environmental and social outcomes.”
– Merle A. Hinrich
Thus, sustainable trade supports not only economic growth, but also environmental protection and strengthened social capital. It involves finding a balance between short-term incentives and long-term resilience.
Measuring Sustainable Trade
The Sustainable Trade Index (STI) is based on three underlying pillars of trade sustainability. Every economy in the STI receives a score between 0 and 100 for each pillar.
|Pillar||Number of Indicators||Examples of Indicators|
The economic pillar measures a country’s ability to to grow its economy through trade, while the social pillar measures a population’s tolerance for trade expansion, given the costs and benefits of economic growth.
Last but not least, the environmental pillar measures a country’s proficiency at managing climate-related risks. Individual pillar scores are then aggregated to arrive at an overall ranking, which also has a maximum possible score of 100.
The Sustainable Trade Index 2020: Overall Rankings
For the first time in the STI’s history, Japan and South Korea have tied for first place. Both countries have placed in the top five previously, but 2020 marks the first time for either to take the top spot.
|1 (tied)||🇯🇵 Japan||75.1|
|1 (tied)||🇰🇷 South Korea||75.1|
|4||🇭🇰 Hong Kong||68.3|
|10||🇱🇰 Sri Lanka||50.4|
|15 (tied)||🇮🇳 India||46.9|
|15 (tied)||🇻🇳 Vietnam||46.9|
Advanced economies like Singapore, Hong Kong, and Taiwan were also strong performers, each scoring in the high 60s. At the other end of the spectrum, developing countries such as India and Vietnam were tightly packed within the 40 to 50 range.
To learn more, here’s how each country performed in the three underlying pillars.
1. Economic Pillar Rankings
Hong Kong topped the economic pillar for the first time thanks to its low trade costs and well-developed financial sector. Financial services have increased their contribution to Hong Kong’s GDP from 13% in 2004 to 20% in 2018.
The region’s recently initiated national security law—which has resulted in greater political instability—may have a negative effect on future rankings.
|1||🇭🇰 Hong Kong||69.6|
|4||🇰🇷 South Korea||63.3|
|5 (tied)||🇲🇾 Malaysia||61.2|
|5 (tied)||🇺🇸 U.S.||61.2|
|9 (tied)||🇯🇵 Japan||58.6|
|9 (tied)||🇵🇭 Philippines||58.6|
|13||🇱🇰 Sri Lanka||54.7|
China was also a strong performer, climbing to third for the first time. Asia’s largest economy benefits from a well-diversified group of trading partners, meaning it doesn’t rely too heavily on a single market.
The bottom five countries—India (16th), Myanmar (17th), Thailand (18th), Pakistan (19th) and Laos (20th)—suffered from issues such as payment risk, which is measured as the difficulty of getting money in and out of a country. This risk is especially damaging to trade because it discourages foreign direct investment.
2. Social Pillar Rankings
The social pillar features the highest average score, but also the largest gap from top to bottom. This gap has expanded over recent years, growing from 43.9 points in 2018 to 52.3 in 2020.
|3||🇰🇷 South Korea||86.9|
|8||🇭🇰 Hong Kong||57.8|
|18||🇱🇰 Sri Lanka||46.1|
Taiwan claimed the top spot for the second time, solidifying its reputation as Asia’s leader in human capital development. It performed well in the educational attainment indicator, with 93.6% of its population receiving a tertiary education.
China, despite its success in other pillars, only managed 16th. This was partly due to the effects of its now defunct one-child policy, which has been responsible for creating gender imbalances and a shrinking population.
3. Environmental Pillar Rankings
The environmental pillar has the lowest average score of the three. Japan, Singapore, Hong Kong, and South Korea were the only countries to score above 75.
|3||🇭🇰 Hong Kong||77.4|
|4||🇰🇷 South Korea||75.2|
|8||🇱🇰 Sri Lanka||50.4|
The top four performed well in areas such as air quality and water pollution, and with the exception of Hong Kong, have all introduced carbon pricing schemes in the past decade. This doesn’t mean these countries are without their flaws, however.
Land-constrained Singapore, for instance, ranked 16th in the deforestation indicator. The city-state is one of the densest population centers in the world, and has cut down forests to clear space for further settlement and urbanization.
Building Back Better From COVID-19
Despite the damage that COVID-19 has caused, there are some silver linings. This includes the environmental benefits experienced by China, where lockdowns reduced carbon emissions by 200 million tonnes in a single month. It’s been estimated that after two months, China’s reduced pollution levels saved the lives of 77,000 people.
These temporary improvements are an explicit reminder of the environmental and social costs associated with economic growth. In response, governments in Asia are taking steps to ensure the long-term sustainability of their nations. Japan and South Korea both announced their commitments to achieving carbon neutrality by 2050, while China set a similar goal for 2060.
Mapping the World’s Key Maritime Choke Points
Ocean shipping is the primary mode of international trade. This map identifies maritime choke points that pose a risk to this complex logistic network.
Mapping the World’s Key Maritime Choke Points
Maritime transport is an essential part of international trade—approximately 80% of global merchandise is shipped via sea.
Because of its importance, commercial shipping relies on strategic trade routes to move goods efficiently. These waterways are used by thousands of vessels a year—but it’s not always smooth sailing. In fact, there are certain points along these routes that pose a risk to the whole system.
Here’s a look at the world’s most vulnerable maritime bottlenecks—also known as choke points—as identified by GIS.
What’s a Choke Point?
Choke points are strategic, narrow passages that connect two larger areas to one another. When it comes to maritime trade, these are typically straits or canals that see high volumes of traffic because of their optimal location.
Despite their convenience, these vital points pose several risks:
- Structural risks: As demonstrated in the recent Suez Canal blockage, ships can crash along the shore of a canal if the passage is too narrow, causing traffic jams that can last for days.
- Geopolitical risks: Because of their high traffic, choke points are particularly vulnerable to blockades or deliberate disruptions during times of political unrest.
The type and degree of risk varies, depending on location. Here’s a look at some of the biggest threats, at eight of the world’s major choke points.
Because of their high risk, alternatives for some of these key routes have been proposed in the past—for instance, in 2013 Nicaraguan Congress approved a $40 billion dollar project proposal to build a canal that was meant to rival the Panama Canal.
As of today, it has yet to materialize.
A Closer Look: Key Maritime Choke Points
Despite their vulnerabilities, these choke points remain critical waterways that facilitate international trade. Below, we dive into a few of the key areas to provide some context on just how important they are to global trade.
The Panama Canal
The Panama Canal is a lock-type canal that provides a shortcut for ships traveling between the Pacific and Atlantic oceans. Ships sailing between the east and west coasts of the U.S. save over 8,000 nautical miles by using the canal—which roughly shortens their trip by 21 days.
In 2019, 252 million long tons of goods were transported through the Panama Canal, which generated over $2.6 billion in tolls.
The Suez Canal
The Suez Canal is an Egyptian waterway that connects Europe to Asia. Without this route, ships would need to sail around Africa, which would add approximately seven days to their trips. In 2019, nearly 19,000 vessels, and 1 billion tons of cargo, traveled through the Suez Canal.
In an effort to mitigate risk, the Egyptian government embarked on a major expansion project for the canal back in 2015. But, given the recent blockage caused by a Taiwanese container ship, it’s clear that the waterway is still vulnerable to obstruction.
The Strait of Malacca
At its smallest point, the Strait of Malacca is approximately 1.5 nautical miles, making it one of the world’s narrowest choke points. Despite its size, it’s one of Asia’s most critical waterways, since it provides a critical connection between China, India, and Southeast Asia. This choke point creates a risky situation for the 130,000 or so ships that visit the Port of Singapore each year.
The area is also known to have problems with piracy—in 2019, there were 30 piracy incidents, according to private information group ReCAAP ISC.
The Strait of Hormuz
Controlled by Iran, the Strait of Hormuz links the Persian Gulf to the Gulf of Oman, ultimately draining into the Arabian Sea. It’s a primary vein for the world’s oil supply, transporting approximately 21 million barrels per day.
Historically, it’s also been a site of regional conflict. For instance, tankers and commercial ships were attacked in that area during the Iran-Iraq war in the 1980s.
The Bab el-Mandeb Strait
The Bab el-Mandeb Strait is another primary waterway for the world’s oil and natural gas. Nestled between Africa and the Middle East, the critical route connects the Mediterranean Sea (via the Suez Canal) to the Indian Ocean.
Like the Strait of Malacca, it’s well known as a high-risk area for pirate attacks. In May 2020, a UK chemical tanker was attacked off the coast of Yemen–the ninth pirate attack in the area that year.
Due to the strategic nature of the region, there is a strong military presence in nearby Djibouti, including China’s first ever foreign military base.
