Introduction to the Legal and Medical Cannabis Landscape
The cannabis industry transitioned from a prohibited, stigmatized, and illegal substance to become legalized for its medical benefits. Over the past few decades, many U.S. states have legalized medical use, but there is limited federal guidance regarding its public health impact.
The Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) tasked the National Academies with assessing cannabis use across the U.S. According to the consensus study report, public health must be inclusive in medical cannabis regulations. Continue reading to know more about the historical perspective, complex legal landscape, and the medical cannabis debate.
Medical Cannabis Overview
Medical cannabis means the therapeutic use of cannabis to alleviate the symptoms of various medical conditions. Patients with a valid registration from healthcare providers can access medicinal cannabis products. In many states and countries, medical cannabis has been legalized after the recognition of its therapeutic benefits.
Key Components: THC and CBD
The cannabis plant contains more than 500 components, with 80 naturally occurring cannabinoids. THC and CBD cannabinoids are the most recognized components of medicinal cannabis products. These cannabinoids interact with the endocannabinoid system of the body and help ease symptoms associated with chronic pain, arthritis, fibromyalgia, etc.
How Medical Cannabis is Used?
THC, being the psychoactive compound, is used for nausea reduction, pain relief, and increasing appetite. However, CBD products are used for reducing inflammation, anxiety, pain, and alleviating symptoms of certain diseases like epilepsy. CBD-derived medication, Epidiolex, has been approved to treat some forms of epilepsy, including Lennox-Gastaut Syndrome and Dravet Syndrome.
Historical Perspective of Medical Cannabis
The origin of cannabis dates back 5000 years, to the ancient world. The early use of medical cannabis was seen in the 16th century in Ebers Papyrus, an Egyptian medical papyrus of herbal knowledge. Cannabis was first used for medical purposes in 400BC. In the U.S., the use of cannabis as a patient medicine started during the 19th and early 20th century.
The federal government restricted the cannabis consumption and sale through the Marihuana Tax Act in 1937. Evolving through the prohibition era, social stigma, and complex legal frameworks, medical use of cannabis under physician supervision was first legalized in California in 1996 under the Compassionate Use Act. Literary references showed that cannabis was widely used in the twentieth century for medical purposes. Research studies show that medical cannabis has been used historically and supported by modern research to ease various women’s health conditions, such as labor pain.
The Legal and Regulatory Landscape
The legal and regulatory landscape of medical cannabis is complex and varies significantly across different regions. At the federal level, cannabis or marijuana is categorized as a Schedule I substance and not allowed for medical use. However, hemp and its derivatives have been removed from Schedule I and legalized. At the state level, as of June 26, 2025, forty states, the District of Columbia, and three territories allowed the use of medicinal cannabis products.
State regulations vary from one another in terms of cannabis consumption, cultivation, licensing processes, and quality control measures. The 1961 UN Single Convention on Narcotic Drugs provides the International framework for all countries, but countries can implement specific regulations regarding medical cannabis. Countries like the Netherlands and Germany have established their medical cannabis program, while Japan restricts it.
Therapeutic Benefits & Clinical Application
Cannabis is now widely recognized for its therapeutic benefits and helps in the treatment of various medical conditions. The clinical trials have proved that the cannabinoids have analgesic properties that help with chronic non-cancer pain conditions, such as fibromyalgia, neuropathic pain, rheumatoid arthritis, and mixed chronic pain. The fifteen clinical trials conducted showed a significant analgesic effect of cannabinoids compared to placebo.
Dronabinol, a synthetic form of delta-9 THC, is approved by the U.S. Food and Drug Administration for the treatment of nausea and vomiting related to cancer chemotherapy and the treatment of HIV-induced anorexia in patients.
Product Variations & Safe Use
-
Product Forms
The medical cannabis products are available in various forms, including tinctures, capsules, edibles, and inhalation products. The key differences in these product forms include delivery methods, desired effects & duration, and the cannabinoids. The inhalation method includes dried flowers and vaping cartridges; the oral ingestion includes capsules, gummies, chocolates, and ingestible oils; the sublingual method involves tinctures; and the topical method includes creams, balms, lotions, and transdermal patches.
-
Quality Control & Safe Dosage
The most important factor in cannabis legalization and consumption is proper quality control by manufacturers and safe usage by consumers. Standard quality control measures include the regulated concentration of THC and CBD, accurate labeling and packaging, Good Manufacturing Practices (GMP), and third-party lab testing. For the safe consumption of medical cannabis, consumers must take the prescribed dosage as per the physician’s instructions.
Medicinal Cannabis Debate: Ethics and Concern
The medicinal cannabis debate revolves around the potential therapeutic benefits of cannabis, with opponents concerned about possible health risks. Moreover, there is ongoing confusion among doctors about prescribing medical cannabis due to varying laws and regulations. They are in conflict between their professional obligations to reduce patient suffering and varying legal regulations.
The other concern in the debate is the lack of large-scale randomized trials to ensure the efficacy and safety of cannabis use. Proponents argue that the evidence supports the botanical medicinal cannabis in treating various medical conditions. THC and CBD cannabis products are relatively safe and inexpensive, with fewer adverse effects compared to pharmaceutical agents. Researchers and clinicians must know all the implications of medical cannabis use and ensure responsible prescribing and consumption.
Future of Medical Cannabis Use
The evolution of cannabis dates back in history. Continuous scientific research is uncovering more therapeutic benefits of cannabis, predicting a future of more comprehensive cannabis laws. The future of medical cannabis shows an increase in investment in research, improved patient access, and prioritizing public health, making the way for responsible consumption and innovative therapies.
Individuals interested in medical cannabis consumption must stay informed of all cannabis updates. The future of medical cannabis might be patient supportive with open-door policies regarding medical cannabis.
Medical Cannabis: Shift from Prohibition to Legalization
Cannabis regulations have gone through the era of prohibition, to social stigma, to legalization for medical use. Still, many states and countries do not allow the medical use of cannabis. Future research and advancements in the cannabis industry might lead to more comprehensive cannabis regulations that prioritize responsible consumption and public health.
