" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

Dr. Mamta Gupta,
"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

The exploration of cannabis, particularly its legitimisation and multifaceted uses, is pivotal in understanding its historical significance, chemical composition, therapeutic potential, and societal implications. This narrative review traverses millennia of cannabis usage for medicinal, recreational, and spiritual purposes, juxtaposed with contemporary legislative shifts, notably in the United States. As perceptions evolve, especially with state-level legalisation contrasting federal prohibition, the review scrutinises the burgeoning use of cannabis products, particularly among youth, and the evolving regulatory frameworks. Neurological effects of cannabis use, including impacts on brain structure and function, are examined alongside potential benefits and risks in various medical contexts. Challenges in conducting rigorous clinical research, primarily due to legal and pharmaceutical constraints, are outlined. The review delves into the complexities of cannabis usage during pregnancy and the conflicting scientific data, presenting challenges in advising expectant mothers. Cannabis’ diverse applications in treating various disorders, ranging from chronic pain to neurological conditions, are explored, shedding light on the potential benefits and limitations. The review highlights the pharmacological dynamics and clinical implications of cannabis-based therapies, emphasising the need for further research to elucidate their efficacy and long-term safety comprehensively. Moreover, the review discusses the pros and cons of CB therapy with high-Cannabidiol (CBD) medicinal cannabis, addressing challenges such as product quality, safety concerns, potential psychoactive effects, drug interactions, and limited research. It underscores the importance of informed decision-making and personalised guidance in navigating the complexities of CB therapy. In conclusion, while cannabis exhibits a wide range of potential medical applications, further research is essential to fully comprehend its therapeutic potential and weigh the associated risks. The review contributes to informed discourse and evidence-based policymaking, emphasising the need for continued research to unlock the full potential of cannabis in healthcare.

Introduction
Marijuana, or cannabis, contains several chemicals, especially Delta-9-Tetrahydrocannabinol (Δ9-THC) and CBD, that may have therapeutic and medical uses. Cannabis sativa has been used for medicinal, recreational, and spiritual purposes for thousands of years. The class of chemicals known as phytocannabinoids is present in the cannabis plant, which is well known for its euphoric and psychoactive properties. The Δ9-THC is the primary psychoactive component of cannabis (1). With the legalisation of cannabis for medical and recreational purposes at the state level in the United States and the nationwide legalisation of the drug for recreational purposes in Canada and Uruguay throughout the past 25 years, perceptions toward the drug have drastically changed (2).

Consequently, there has been a significant rise in the use of cannabis products, especially among young people. Over the past fifty years, states have experimented with marijuana legalisation policies, even though federal law has outlawed the use and distribution of marijuana in the United States since 1937 (3). The 1970s saw the enactment of state decriminalisation measures, the 1990s saw the adoption of patient medical access laws, and more recently, several jurisdictions have started experimenting with legalising recreational markets. As a result, there is a range of marijuana liberalisation laws in the US that are frequently overlooked or underappreciated when assessing more recent legislative initiatives. Research on structural neuroimaging has consistently demonstrated that individuals who use cannabis display irregularities in the volume and density of their hippocampus (2). Since white matter contains a high concentration of Cannabinoid-1 (CB1) receptors, there is also compelling evidence in the literature that cannabis usage damages this area of the brain (4). One way to interpret the term “medical marijuana” is as a marketing ploy meant to lower the perceived danger associated with drug use (5).

From this angle, the misconception that marijuana is safe for medical usage has led to the perception in the general unconscious that it is beneficial to health. The female marijuana plant has the most significant levels of over 100 cannabinoids, whereas both the male and female varieties of the plant have over 400 chemical substances in total (6). The primary component in cannabis that has psychoactive properties is Δ9-THC, and this compound’s effects are linked to problems with memory, learning, attention, and motor coordination (7). Although there are pharmacological grounds for the possibility that cannabinoids have positive benefits, there is insufficient data from clinical trials to make certain judgments. Studies have shown that pure Δ9-THC is beneficial in increasing appetite, managing nausea and vomiting, and reducing spasticity in those with Multiple Sclerosis (MS) (1),(5),(6),(8).

Additionally, CBD is beneficial in treating paediatric epilepsy disorders. The federal laws governing high-THC cannabis in the USA and the reluctance of big pharmaceutical companies to fund clinical trials that won’t result in a prescription medicine with patent protection are the main obstacles to research on cannabis, cannabis extracts, and CBD oil (9). Cannabis exposes foetuses and neonates since it crosses the placenta and enters breast milk (10). Many pregnant women provide medical justifications for using marijuana, including chronic pain, anxiety, and pregnancy-related nausea and vomiting (6). Due to conflicting scientific data on marijuana use during pregnancy, professionals are unsure how to advise expectant mothers about the hazards associated with marijuana usage.

In this review, the authors aim to explore the multi-faceted landscape surrounding marijuana, or cannabis, shedding light on its historical significance, chemical composition, therapeutic potential, and societal implications. By delving into the rich history of cannabis usage spanning thousands of years for medicinal, recreational, and spiritual purposes, the authors set the stage for a comprehensive examination of its modern-day complexities. With the shifting legal landscape, particularly in the United States, where state-level legalisation contrasts with federal prohibition, understanding the implications of these policies becomes paramount. This present review also scrutinises the burgeoning use of cannabis products, especially among youth, and the evolving regulatory frameworks that attempt to navigate this cultural and medical phenomenon. Furthermore, the authors here delve into the scientific literature to explore the neurological effects of cannabis use, including its impact on brain structure and function, as well as its potential benefits and risks in various medical contexts. By addressing the challenges in conducting rigorous clinical research due to legal and pharmaceutical constraints, as the aim of this review was to provide a nuanced understanding of the complexities surrounding cannabis use and its potential therapeutic applications. This review helps to contribute to informed discourse and evidence-based policymaking in this rapidly evolving field.

Literature Search

A comprehensive review of scholarly databases, medical literature, and reliable sources was conducted to learn about the legal developments, historical uses, and potential medical benefits of cannabis. A few of the most crucial search terms, including “cannabis,” “medical marijuana,” “CB,” “THC,” “CBD,” and “neurological disorders,” An extensive evaluation of research papers, reviews, and clinical trials was done to summarise the topic comprehensively. The exclusion criterion ensured that redundant or non-peer-reviewed materials were excluded, while the inclusion criteria concentrated on relevance to the research topic. By integrating varied viewpoints, endeavoured to offer an all-encompassing and empirically grounded investigation of the diverse facets of cannabis consumption.

Cannabis: Origins, Components, and Therapeutic Applications

Often known as marijuana or weed, cannabis is a psychoactive drug extracted from the cannabis plant. Cannabis naturally comes from the same class of drugs that people use regularly, including tobacco, alcohol, and coffee (11). The cannabis plant, native to Central or South Asia, has long been used in traditional remedies and as a recreational and entheogenic narcotic (3). THC, one of the plant’s 483 identified compounds, is the main psychoactive component of cannabis. Atleast 65 other cannabinoids, such as CBD, are also present (12). Overuse of marijuana has been linked to several adverse health impacts as well as socio-economic consequences (13). Preventing kids from experimenting with and routinely consuming marijuana has emerged as a significant public health problem.

Cannabis can be consumed as an extract, smoked, vaped, or added to food. In addition to treating chronic pain, headaches, migraines, anxiety, and post-traumatic stress disorder, medicinal cannabis is recommended for the treatment of numerous other illnesses’ symptoms (14). The active components of cannabis, THC and CBD, influence the symptoms of the patient. The endo-cannabinoid system represents these substances that reduce nociception and the frequency of symptoms (5). Rimonabant, an inverse agonist of the CB1 receptor, substantially decreased body weight, enhanced tolerance to glucose, and reduced other cardiovascular risk factors (15).

Rimonabant and its Adverse Effects: Unveiling Pharmacological Dynamics and Clinical Implications

Although rimonabant was approved in Europe, it was later taken off the market due to reports of depression and suicide. It is significant to remember that a drug that lowers a receptor’s activity below the baseline level is referred to in pharmacology as an inverse agonist. In contrast, a neutral antagonist raises the receptor’s activity to the baseline level (3). Given that euphoria and increased appetite are recognised effects of marijuana, it is not surprising that an inverse agonist causes anorexia, depression, and weight loss (9). Current recommended medications, such as pregabalin, gabapentin, duloxetine, and other tricyclic anti-depressants, provide meaningful pain relief for over fifty percent of patients; this suggests that there is a clinical need that is not being satisfied for the treatment of neuropathic pain (7). Medical Cannabis (MC) and Cannabis-based Medicines (CbMs) have been proposed as potential treatments for people who experience chronic neuropathic pain (16). The CbMs/MC come in a variety of forms: legal pharmaceuticals or medical goods (plant-derived and synthetic products like THC or CBD); medicinal applications of cannabis plant derivatives with defined molecular content, like dronabinol (THC); and natural cannabis with defined levels of THC and CBD along with additional active ingredients (phytocannabinoids in addition to CBD/THC, aromatic compounds, and flavonoids) (6),(11),(13). CB1 in medical treatment is represented in (Table/Fig 1).

Recreational Cannabis Legalisation: Unveiling Health Concerns and Historical Perspectives

Cannabis usage for recreational purposes is now legal in Colourado and Washington, thanks to recent laws reflecting shifts in public opinion. Unfortunately, the discussion surrounding the legalisation of marijuana for recreational purposes has not focused much on the drug’s detrimental health effects (17). These detrimental effects are frequently more noticeable in teenagers. Based on the detrimental consequences on the health of adults and adolescents, a strong case can be made to veer away from the path that society is taking in favour of legalising marijuana for recreational use (8),(14). However, given that cannabis exposure may have long-term effects on this population, children and adolescents may be more susceptible to cannabis infection than adults (18). In the US, marijuana usage was mainly restricted to specific demographics until it was legalised. The 1960s counter-culture saw a sharp rise in marijuana use before the Controlled Substances Act of 1970 (19). These included anti-war demonstrators, college staff and students, and “hippies” in the mid-1960s (3). Medical marijuana patients use the drug for things like pain, epileptic fits, vomiting, desire to eat, and psychological problems have become more and more apparent (20).

Medical Marijuana: Diverse Applications and Complex Considerations in Treatment

The use of medical marijuana is limited to treating a variety of disorders, such as extreme pain, muscular spasms, and terminal illnesses. Still, it can also be used to treat cancer, HIV/AIDS, epilepsy, glaucoma, and other conditions (21). It includes everything from mental health diseases like post-traumatic stress disorder to neurological conditions like Alzheimer’s and MS (2). Medical marijuana and its related substances may help treat a variety of ailments, such as behaviour and development problems in kids and teenagers (22). Marijuana’s potential applications in treating behavioural and developmental disorders, including Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD) (8). Natural CBD is effective for a limited range of children’s seizures in rigorous scientific testing (23). Known adverse effects of that medicine include drowsiness, liver impairment, and suicidal thoughts and actions (23).

It is challenging to treat Cystic Fibrosis (CF) with marijuana because the drug is frequently smoked or vaporised, and it is not advised for those with chronic lung diseases to breathe in marijuana smoke or vapour (24). There is no proof that using vaporisation or other alternate delivery methods is safer than smoking. The complexity of ASD makes it extremely difficult to identify a suitable treatment, necessitating numerous drug adjustments or trials of treatment throughout a patient’s lifetime (23). Medical cannabis in diverse health conditions is represented in (Table/Fig 2).

Medical Cannabis (MC): Addressing Varied Symptoms and Conditions through Cannabinoid (CB) Therapy

Patients and symptoms seek different degrees of safety, tolerability, and efficacy with commonly prescribed drugs. Some of the most often reported adverse effects are aggression, anxiety, irritability, and a detrimental impact on cognition, which are also thought to be the most concerning symptoms associated with ASD (2). As a result, many patients stop using the medication because the side effects exceed the benefits. The potential efficacy, safety, and tolerance of using medicinal cannabis high in CBD for treating ASD symptoms, including irritability and sleep disturbances, have been demonstrated by recent case reports and retrospective investigations (25).

The quality of life of patients is significantly impacted by inadequate management of neuropathic and chronic pain related to cancer. Alternative therapeutic options are necessary for patients who do not respond well to opioid analgesics or who experience severe adverse effects from using standard analgesics (4). Medical cannabis may be able to help this patient population manage cancer pain (26). Marijuana use can help control sickle cell disease, although more research is required for the same (27). THC and its derivatives are psychotropic. Δ9-THC is used to treat Chemotherapy-Induced Nausea and Vomiting (CINV) (28). Marijuana laws have been extended to cover the following common medical conditions: illnesses such as MS and muscle spasms, immunodeficiency syndrome, carcinoma, Crohn’s disorder, Amyotrophic Lateral Sclerosis (ALS), cachexia, glaucoma, epileptic seizures, hepatitis C virus, and MS (29). Following therapy with medical marijuana, a notable improvement can be shown in the neurologic symptoms of spasms, tremors, spasticity, chorea, and sleep quality (30). The interactions between cannabinoids and the CB1 and CB2 receptors, found in many locations throughout the human body, produce the pharmacological effects of cannabinoids (1). Cannabis is a medicinal substance used to alleviate emesis and discomfort (30).

Pros of Cannabinoid (CB) Therapy with High-CBD Medicinal Cannabis

Cannabinoid (CB) therapy, mainly using high-CBD medicinal cannabis, has emerged as a promising avenue for addressing diverse health concerns. CBD, the non-psychoactive compound found in cannabis, offers a range of potential benefits. Firstly, its analgesic properties provide hope for individuals coping with chronic pain conditions, potentially offering relief where other treatments have fallen short (2). Additionally, CBD’s anti-inflammatory effects hold the potential for managing conditions characterised by inflammation, such as arthritis and inflammatory bowel diseases, offering a natural alternative to traditional anti inflammatory medications (25),(31).

Moreover, research suggests that CBD may play a role in anxiety and depression management, acting as an anxiolytic and anti-depressant, thereby enhancing mental well-being (27). Furthermore, the neuroprotective properties of CBD present opportunities for combating neurodegenerative diseases like Alzheimer’s and Parkinson’s by reducing inflammation and oxidative stress in the brain, potentially slowing disease progression (25). Lastly, the FDA approval of CBD for certain types of epilepsy underscores its anti-seizure effects, providing hope for individuals with treatment-resistant forms of epilepsy to achieve better seizure control (29),(30),(31).

Cons of Cannabinoid (CB) Therapy with High-CBD Medicinal Cannabis

However, despite the potential benefits, Cannabinoid (CB) therapy, especially with high-CBD medicinal cannabis, presents notable challenges. The lack of regulation in the cannabis industry raises concerns regarding product quality, potency, and safety, leaving consumers vulnerable to exposure to contaminants or mislabeled products (2),(3),(31). Additionally, while CBD itself is non-psychoactive, high-CBD cannabis products may contain trace amounts of THC, potentially leading to unwanted psychoactive effects, particularly in individuals sensitive to THC or when consumed at higher doses (25),(31). Furthermore, CBD can interact with certain medications, altering their metabolism and efficacy, necessitating caution and close monitoring, especially for individuals on multiple medications (27).

Although generally well-tolerated, CBD may induce side effects such as fatigue, diarrhoea, and changes in appetite or weight, affecting the overall tolerability of CB therapy (3),(5),(30),(31). Lastly, despite growing interest, research on CB like CBD is still in its early stages, with limited conclusive evidence regarding their efficacy and long-term safety for various conditions, highlighting the need for further research and clinical trials to elucidate their therapeutic potential and risks comprehensively (28),(30). Thus, while CB therapy offers promise for addressing various health issues, it’s essential for individuals to carefully weigh the potential benefits against the risks and consult with healthcare professionals for personalised guidance and monitoring (31).
Conclusion
In summary, the extensive historical usage of cannabis for medicinal, recreational, and spiritual purposes has led to recent changes in legislation, most notably the legalisation of marijuana in several states for both medical and recreational purposes. The two main psychotropic ingredients, CBD and Δ9-THC, have received the most attention from scientists. The review underscores the historical and recent shifts in cannabis legislation, noting its multi-faceted usage and the attention CBD and THC receive from researchers. Concerns about cognitive effects in cannabis users are raised, alongside critiques of the term “medical marijuana” for potentially downplaying risks. While acknowledging its medical potential, caution is urged due to known adverse effects, particularly in conditions like MS and cancer symptoms. Challenges in cannabis research and complexities in US legalisation are highlighted, emphasising the need for further research to fully grasp its medical applications.
