Historical Importance of Medical Cannabis
The history of medical cannabis is rich and varied, stretching back thousands of years and spanning numerous cultures and regions. This section studies the significant milestones and developments that have shaped the understanding and use of cannabis in medicine.
Ancient Origins
The origins of cannabis can be traced back to the ancient world, with extensive evidence indicating its use over 5,000 years ago. Archaeological findings suggest that cannabis was cultivated in what is now modern-day Romania. It was used for both its psychoactive properties and its potential medicinal benefits.
- Ancient China and India: In ancient China, cannabis was used as a treatment for various ailments. The earliest recorded use is attributed to Emperor Shen Nung in 2737 BC. He documented its effectiveness in treating gout, rheumatism, malaria, and poor memory. Cannabis was also a key component of traditional Indian medicine. Known as “bhang,” it was used in Ayurvedic medicine for pain relief, digestive issues, and stress reduction. “Bhang” is still used in India to create a drink during the Holi festival.
- Egypt and the Middle East: Ancient Egyptians utilized cannabis for its anti-inflammatory and pain-relieving properties. It was found in the tomb of Pharaoh Ramses II, who died in 1213 BC. This discovery suggests the importance of cannabis in ancient Egyptian medicine. Similarly, in the Middle East, cannabis was used to treat epilepsy and as an anesthetic.
Medieval and Renaissance Europe
- Medieval Applications: In medieval Europe, cannabis continued to be used medicinally. Manuscripts from this period describe its application in treating ailments such as coughs, jaundice, and colic. Hildegard of Bingen, a German herbalist (12th century), recommended cannabis treatments for conditions like migraines and joint pain.
- Renaissance Rediscovery: During the Renaissance, the resurgence of interest in science and herbal medicine led to renewed attention to cannabis. Notable physicians like Garcia de Orta and Li Shizhen wrote extensively about the plant’s medicinal properties. Their works helped spread knowledge of cannabis’s potential benefits across Europe and Asia.
19th and Early 20th Century in the United States
- Patent Medicines: In the United States, cannabis was widely used as a patent medicine during the 19th and early 20th centuries. It was an ingredient in numerous over-the-counter remedies, marketed for everything from pain relief to anxiety reduction. Cannabis was so common in these medicines that it was included in the United States Pharmacopoeia in 1850.
- Medical Acceptance: Prominent physicians of the time, such as Sir William Osler, considered cannabis an effective treatment for migraines. Cannabis tinctures were commonly prescribed and were readily available in pharmacies across the country.
Medical Cannabis: Federal Restrictions and Legal Challenges
- The Marijuana Tax Act of 1937: The tide began to turn against cannabis in the 20th century with the introduction of the Marijuana Tax Act of 1937. This act imposed heavy taxes and regulations on the sale and use of cannabis. Taxes made it difficult for physicians and pharmacists to continue using it as a treatment. The act marked the beginning of federal restrictions on cannabis. It was driven largely by political and social factors rather than medical evidence.
- The Controlled Substances Act of 1970: Three decades later, the Controlled Substances Act of 1970 classified marijuana as a Schedule 1 drug, the most restrictive category. Cannabis shared this category with drugs like heroin and LSD! Needless to say, marijuana was considered to have a high potential for abuse and no accepted medical use. This legislation effectively outlawed marijuana for any purpose, including medical use, and severely hindered research into its medicinal properties.
- Impact on Research: The classification of marijuana as a Schedule 1 drug created significant barriers for researchers. Obtaining approval and funding to study the medical benefits of cannabis became incredibly challenging. As a result, what followed was a decades-long stagnation in scientific research.

Legalization of Medical Cannabis
The journey towards the legalization of medical marijuana in the United States has been long and complex. This section explores the key milestones and legislative changes that have paved the way for the current landscape of medical cannabis use.
The Controlled Substances Act of 1970
The Controlled Substances Act (CSA) of 1970 marked a significant turning point in the legal status of marijuana. By classifying marijuana as a Schedule 1 drug, the CSA indicated that cannabis had a high potential for abuse. Also, it was deemed no accepted medical use, and a lack of accepted safety for use under medical supervision. This federal classification effectively outlawed marijuana, creating substantial obstacles for its medical use and research.
The First Steps Towards Legalization
- California’s Compassionate Use Act of 1996: More than 25 years after the CSA, California became the first state to challenge the federal stance on medical marijuana. The enactment of Proposition 215, known as the Compassionate Use Act of 1996, allowed patients and their primary caregivers to possess and cultivate marijuana for medical purposes with a physician’s recommendation. This groundbreaking legislation set a precedent and sparked a national conversation about the potential medical benefits of cannabis.
- The Movement Gains Momentum: Following California’s lead, other states began to consider similar measures. By the early 2000s, states such as Oregon, Washington, and Alaska had passed their own medical marijuana laws. Early adopters faced significant federal pushback, but their persistence laid the groundwork for broader acceptance and further legislative efforts.
Expansion and Acceptance of Medical Cannabis
- The 2010s – A Decade of Change: The 2010s saw a dramatic shift in public opinion and state legislation regarding medical marijuana. Colorado and Washington legalized recreational marijuana in 2012, which indirectly bolstered the case for medical marijuana. As more states observed the economic benefits and manageable public health impacts, medical marijuana legislation gained traction.
- Medical Marijuana in the Majority: By 2016, a significant number of states had legalized medical marijuana. This momentum continued! Today, 36 US states, four territories, and the District of Columbia have laws permitting the use of medical cannabis. These laws vary in scope and regulation. Some states allow a broad range of conditions to be treated with cannabis. On the other hand, others have more restrictive lists of qualifying conditions.
Federal Stance and Ongoing Challenges
- Federal Prohibition: Despite widespread state-level legalization, marijuana remains illegal at the federal level under the CSA. This federal prohibition creates numerous challenges for patients, providers, and researchers. This situation has created a lack of access to banking for cannabis businesses. Entrepreneurs find it difficult to conduct comprehensive research due to funding and approval barriers. And then, there are the overarching legal risks associated with cannabis use and distribution.
- The Rohrabacher-Farr Amendment: A significant development at the federal level was the passage of the Rohrabacher-Farr Amendment in 2014. It prohibits the Justice Department from using federal funds to interfere with the implementation of state medical marijuana laws. While not a full legalization, it provided some protection for medical marijuana programs. Also, it reduced the risk of federal crackdowns in states where medical marijuana is legal.
Current Landscape and Future Directions
- State-Level Innovations: States continue to innovate and expand their medical marijuana programs. Recent trends include the inclusion of more qualifying conditions, the development of comprehensive regulatory frameworks, and efforts to ensure patient access and product safety. Some states are also exploring the integration of medical marijuana into broader healthcare systems, aiming to reduce stigma and improve patient outcomes.
