Cannabis is perhaps the most fascinating and authentic plant in the world. Its seeds can be eaten or pressed into an oil with very low saturated fat content. It is also one of the world's finest natural fibers, used for weaving cloth for over 6,000 years . It was likely used in religious ceremonies thousands of years BC, and hemp cloths have been found as burial goods in tombs from Egypt to China.
In the United States, it was cultivated during the time of George Washington, and it was even used by Becky Ross (the sewer of the first American flag) to make flags. Today, cannabis is grown on every continent except Antarctica and is used to make everything from paper to everyday consumer goods. Sooner or later, you'll encounter cannabis when you look back at human history.
In recent decades, many uses of cannabis have been obscured, but this wasn't always the case. For example, Queen Victoria in the 19th century believed cannabis was the culprit behind menstrual cramps. And as early as 2700 BC, ancient China used cannabis for medicinal purposes. While 20th-century political factors transformed cannabis into a threat, for most of human history, it has been used for medicine and textiles.
The paradoxes of this plant only add to its mystery and intrigue. With an estimated 192 million users worldwide, it is the most common and widely used recreational drug in the world, yet it is illegal in almost every country on Earth. There is evidence that cannabis has genuine therapeutic effects on chronic pain. However, research shows that it also increases the risk of mental illness. To understand why cannabis has such a wide range of uses and effects, we must first understand the unique way this plant works.
Cannabis contains over 480 chemical components, some of which can have opposite effects. Take CBD, for example, a calming and anti-inflammatory compound, and the second most prevalent phenolic compound in most cannabis varieties. Unlike THC, it is inherently non-psychedelic, so it doesn't produce a noticeable high. CBD has been approved by the FDA for treating seizures in patients with Lennox-Gastaut or Dravet syndrome, but CBD proponents claim it can do much more. In fact, CBD is touted as a treatment for everything from acne to heart health. CBD-infused lattes are sold in trendy New York cafes, and health stores sell CBD lotion as a topical pain reliever.
CBD stands in stark contrast to THC, the most dangerous chemical in most cannabis varieties. THC is the primary cause of many of the most well-known effects of cannabis, and unlike CBD, THC can fundamentally alter a user's perception. Although THC and CBD are chemically similar and are often consumed together, their effects are quite different and even seem to interfere with each other. This is because CBD appears to mitigate the effects of THC.
Analyzing a plant containing two very different chemicals is difficult enough, but cannabis has nearly 500 chemicals. Other compounds, such as CBN, THCA, CBG, and so on, each have their own roles, and research is only just beginning. CBN is touted as a natural sleep aid, while THCA is thought to offer the benefits of THC without the stimulating effects. Against all the stereotypes about drugs damaging the brain, early reports claimed that CBG might even help create new brain cells. One thing is clear: despite humans cultivating cannabis for thousands of years, there is still so much to learn about this plant.
Perhaps no plant is known to the public, yet it is so little known. A significant misconception about cannabis remains on both sides of the debate. Anti-cannabis advocates link cannabis to moral depravity, regardless of its medicinal effects or value.
On the other hand, some cannabis proponents claim that because cannabis is a "natural" plant, it is harmless. This is not true; in fact, many natural things are extremely dangerous. For example, the "death cap mushroom" (Amanita phalloides) is both natural and organic, but as its name suggests, it is also extremely deadly. Cannabis is a powerful plant with various medicinal values and the potential to help many patients, but it is not a panacea, and its use can bring real risks and side effects.
The best available evidence suggests that cannabis can treat chronic pain and some symptoms associated with multiple sclerosis. Given that prescription opioids have caused tens of thousands of deaths in the United States in recent years, cannabis stands out as a potential alternative for pain sufferers. There is also some evidence that cannabis can improve problems with chronic pain, fibromyalgia, and obstructive sleep apnea.
CBD is also a promising antipsychotic drug. Some studies suggest it may have some ability to inhibit, but not cure, lung cancer, high blood pressure, and seizures, but further research is needed to confirm its many potential uses.
While cannabis has important medical benefits, like any drug, it also has side effects. These include anxiety, confusion, drowsiness, nausea, paranoia, and hallucinations. Furthermore, cannabis appears to increase the risk of mental illnesses such as depression and schizophrenia in users.
Despite its promising future, cannabis is illegal in almost every country on Earth, yet this hasn't stopped it from being the world's most popular illicit narcotic. Cannabis is the most produced, trafficked, and consumed narcotic in the world.
According to UN estimates, in 2017, 3.9% of the world's population aged 15 to 64 used cannabis. From 2009 to 2014, more than 129 countries reported cannabis cultivation, although the majority of the world's cannabis is grown in the United States and Mexico, with significant hydroponic cannabis cultivation taking place in Canada, where it is grown indoors in nutrient-rich water. Morocco and Afghanistan produce substantial amounts of cannabis resin, much of which is subsequently smuggled to Europe, Pakistan, and Iran. Cannabis use is prevalent in both low- and high-income countries, but less so in middle-income countries.
Despite the promises made by medical marijuana, it remains illegal across the United States under federal law. In late 2018, the U.S. passed an agricultural bill that legalized industrial hemp, but FDA Commissioner Scott Gottlieb dismissed any speculation that CBD products are now legal, stating in a press release, “Selling unapproved products with unproven claims of therapeutic efficacy not only violates the law but could also put patients at risk, as these products have not yet been proven safe or effective.” As long as marijuana remains illegal at the federal level, users and businesses should be aware of the risk of prosecution.
On the other hand, cannabis-related businesses continue to be severely restricted by cannabis's status as a continuing illicit drug. Banks refuse to fund cannabis businesses due to concerns about federal drug charges, forcing them to operate in cash. Major retailers do not stock cannabis products, and investors are hesitant to invest in companies that are strictly involved in the illegal drug trade.
Of course, current policies cannot last forever. Cannabis is classified as a Schedule I drug (Note: UN Convention on the Law of the Sea 1961), meaning it has no "recognized medical use." However, CBD, a cannabinoid and one of the most common compounds in cannabis, is approved by the FDA. State-level cannabis legalization is a $7 billion industry, but technically every transaction violates federal law. Approximately 50% of Americans will have tried cannabis in their lifetime, and 85% support medical marijuana, which is currently legal under state laws in most states. Changes to cannabis legalization are imminent, but it's unclear exactly when.
As revealed in the National Geographic special issue, the cannabis plant contains over 480 chemical compounds. Its complex chemical profile, coupled with its vast yet controversial medical prospects, makes "how to safely and accurately extract active ingredients" the key to bridging the gap between science and commerce. In the face of the immense potential of non-psychoactive components like CBD (cannabidiol) in areas such as anti-seizure and anti-inflammatory treatments, alongside the strict regulatory requirement to avoid risky substances like THC (tetrahydrocannabinol), CBD oil extraction equipment is no longer just simple processing machinery. It has become the core safeguard for ensuring the safety and efficacy of medical-grade products.
Modern CBD extraction equipment (such as supercritical CO2 extraction systems, cryogenic ethanol extraction systems, and molecular distillation equipment) utilizes precise temperature and pressure control, along with closed-loop solvent recovery technology. This enables the targeted separation and high-purity refinement of target compounds without degrading heat-sensitive terpenes and active molecules. This not only physically eliminates the risks of residual solvents and excessive impurities associated with traditional extraction methods, but also meets the stringent pharmaceutical-grade safety standards demanded by regulatory bodies like the FDA. Furthermore, it provides solid technical support for the cannabis industry's transition from a "gray area" into a standardized, modern medical and wellness sector. Ultimately, it is the continuous evolution of these cutting-edge extraction technologies that allows this ancient plant, fraught with paradoxes and mysteries as described by National Geographic, to truly shed its controversial exterior and be transformed into health and well-being for humanity.
