Medicinal Use Of Cannabis Research Articles

Knowledge and perspectives about medicinal cannabis in nurses and nursing students in Portugal

Abstract Background The opening up of legislation on medicinal cannabis in recent years has been a determining factor in the growth of this therapy. In Europe, regulation of medicinal use is a reality in several countries. Nurses can play a leading role in its administration, helping to ensure that it is carried out more effectively and assuming a fundamental role in the success of the therapy. It is therefore pertinent to analyze the knowledge of nurses and nursing students in Portugal about medicinal cannabis. Methods Quantitative descriptive study. A self-completion questionnaire was drawn up and made available on the google forms platform. It was face-validated, content-validated and approved by the Ethics Committee. The instrument included sociodemographic data, questions about cannabis knowledge and perspectives. Descriptive statistics were analyzed. Results Out of a total of 610 responses, 318 were nurses and 292 nursing students. Medical cannabis is considered legitimate by 79.6% of nurses and 84.3% of students. When asked about the functions of the endocannabinoid system, 71.7% of nurses and 79.5% of students said they had no knowledge. 88.7% of nurses and 79.5% of students disagreed that they had sufficient knowledge to advise users on the use of medicinal cannabis. Also, 38.4% believe that their patients use cannabis illegally to manage the symptoms of illnesses. Conclusions There is a need for continuing training for nurses and for the undergraduate and postgraduate nursing curricula to include this emerging area. Key messages • The results show that this issue is a public health problem. It reinforces the need to formulate public policies in this area and to implement training for nurses and nursing students. • These measures will be fundamental in preventing the use of illegal cannabis and promoting the safe use of medicinal cannabis.

O IMPACTO DA REGULAÇÃO DO SISTEMA ENDOCANABINOIDE NA FARMACOTERAPIA DA ANSIEDADE E DO ESTRESSE

This article addresses the impact of regulation of the endocannabinoid system on the pharmacotherapy of anxiety and stress, topics of increasing relevance in neuroscience and pharmacology. The endocannabinoid system, composed of receptors, endocannabinoids and enzymes responsible for their synthesis and degradation, plays a fundamental role in modulating several physiological functions, including the regulation of stress and anxiety. Cannabidiol (CBD), a phytocannabinoid, has stood out for its anxiolytic and modulating effects on the endocannabinoid system, presenting itself as a promising therapeutic alternative for anxiety disorders. The objective of the study was to analyze the therapeutic effects of regulating the endocannabinoid system in the treatment of anxiety and stress, focusing on the benefits and limitations of using CBD. To this end, a bibliographic review of studies published between 2010 and 2024 was carried out, using databases such as PubMed, SciELO and Google Scholar. Inclusion criteria involved peer-reviewed studies that addressed the relationship between the endocannabinoid system and anxiety disorders. The results showed that CBD can significantly reduce symptoms of anxiety and stress, with few side effects. However, there are still gaps regarding optimal dosage and drug interactions, which limits its widespread clinical adoption. Regulation of the medicinal use of cannabis has also proven to be an obstacle in several countries. It is concluded that, despite the challenges, the use of cannabinoids such as CBD represents a promising approach, requiring greater investment in clinical research and adequate regulation.

Changes in Pain and Mental Health Symptoms Associated with Prescribed Medicinal Cannabis Use: A One-Year Longitudinal Study.

Chronic pain and mental health issues like depression and anxiety significantly contribute to disease burden in Western countries. While cannabinoids are suggested to have analgesic, anxiolytic and antidepressant properties, evidence, especially for long-term use, is inconclusive. This 12-month observational study evaluated the effects of prescribed medicinal cannabis for 96 patients suffering from pain, as well as sleep disturbances, depression and anxiety. Treatment outcomes for pain, depression, anxiety and sleep problems were assessed at 3, 6, and 12 months using validated instruments. Significant reductions were observed in pain scores and the interference of pain on daily functions, alongside improvements in mental health and sleep. Many patients reported notable improvements in pain severity and reduced use of pain medications in the first 6 months, with a decline at 12 months. Additionally, sustained improvements in depression, anxiety, stress and sleep were observed, with about half reporting substantial improvement. Adverse effects were common but mostly mild or moderate, most commonly dry mouth and sleepiness. These results show that prescribed medicinal cannabis treatment is associated with improvements in chronic pain and mental health symptoms, such as depression, anxiety and stress. However, findings also suggest reduced effectiveness with longer-term use, emphasizing the need for additional research.

An Exploration of Registered Nurses' Experiences Caring for Patients Taking Medicinal Cannabis.

This study aimed to describe nurses' experiences caring for patients who use medicinal cannabis. For the purpose of this study, the term 'medicinal cannabis' is used to describe cannabis-based products that are sourced legally or illegally. Qualitative study using thematic analysis. Eleven registered nurses explored their experiences caring for patients using medicinal cannabis in the Australian healthcare sector. Semistructured interviews were via telephone, Zoom or face to face. Transcribed interview data were analysed using the six phases of thematic analysis. The nurses' experiences of caring for patients who use medicinal cannabis were described in three themes; 'Searching for predictable processes of regulation, access and use of medicinal cannabis', 'One conundrum after another' and 'There is a lot to learn'. Overall, nurses described feeling underprepared to care for patients who use or want to use medicinal cannabis in the Australian healthcare sector. The results indicate that nurses want to have meaningful discussions with patients about the use of medicinal cannabis, yet do not always have the confidence to do so. Nurses sought their own education on how to better support patients. All participants echoed the need for education. The nurse's role in caring for and supporting patients using medicinal cannabis could improve the patient experience. Nurses play an essential role in improving the patient's experience and advocating for those using or wanting to discuss medicinal cannabis as a part of holistic care. Defining the nurse's role in effectively caring for patients can begin by providing evidence-based education to nurses. Including nurses in policy development and beginning to understand the legal and regulatory implications for nurses are important. This is the first study presenting current issues for nurses who care for patients using medicinal cannabis in Australian healthcare systems. COREQ guidelines were adhered to for this study. For this research project on the experiences of registered nurses caring for patients using medicinal cannabis, we did not engage members of the patient population or the general public.

Use of phytocanabinoids in animal models of Parkinson's disease: Systematic review

This systematic review was carried out with the aim of evaluating the use of medicinal Cannabis for the treatment of Parkinson's disease in experimental models. Furthermore, we sought to understand the main intracellular mechanisms capable of promoting the effects of phytocannabinoids on motor disorders, neurodegeneration, neuroinflammation and oxidative stress. The experimental models were developed in mice, rats and marmosets. There was a predominance of using only males in relation to females; in three studies, the authors evaluated treatments in males and females. Drugs were used as inducers of Parkinson's disease: 6-hydroxydopamine (6-OHDA), 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), lipopolysaccharide (LPS), and rotenone. Substances capable of promoting catalepsy in animals were also used: haloperidol, L-nitro-N-arginine (L-NOARG), WIN55,212–2, and reserpine. The inducing agent was injected stereotaxically or intraperitoneally. The most commonly used treatments were cannabidiol (CBD), Delta-9-tetrahydrocannabinol (Δ-9 THC) and Delta-9-tetrahydrocannabivarin (Δ-9 THCV), administered intraperitoneally, orally, subcutaneously and intramuscularly. The use of phytocannabinoids improved locomotor activity and involuntary movement and reduced catalepsy. There was an improvement in the evaluation of dopaminergic neurons, while in relation to dopamine content, the treatment had no effect. Inflammation, microglial/astrocyte activation and oxidative stress were reduced after treatment with phytocannabinoids, the same was observed in the results of tests for allodynia and hyperalgesia.

Conceptualizing problematic use of medicinal Cannabis: Development and preliminary validation of a brief screening questionnaire.

The use of Medicinal Cannabis (MC) for treating chronic pain is increasing, globally, yet the definition of problematic MC use remains unclear. Defining problematic use of cannabis in medical and non-medical contexts may be fundamentally different since individuals prescribed MC often experience physical dependence, which do not necessarily imply pathology. We aimed to conceptualize problematic use of MC and develop a brief questionnaire for identifying and quantifying problematic MC use. Content validation used a broad definition of problematic substance use, adapting and compiling an initial list of 36 items from various sources: (a) screening tools for assessing problematic prescription opioid medication use; (b) screening tools for problematic recreational cannabis use and (c) qualitative interviews with MC patients. 390 American self-identified chronic pain patients holding a MC card rated each item from the initial list on a 5-point frequency scale and filled out questionnaires assessing various clinical outcomes. Following initial item titration, a multi-group measurement invariance comparison strategy, using two external indicators: alcohol-related problems and depression, resulted a final eight-item list that met fit quality in a baseline model, presented excellent internal consistency reliability (α=0.929), and significantly correlated with anxiety and low quality of life. Items in the final list related predominantly to negative consequences of MC use. Problematic use of MC is characterized by negative physiological, social, emotional and functional consequences. The final eight-item list was named the Medicinal Cannabis Negative Consequences Scale (MCNCS), emerging as a brief measure for problematic MC use and demonstrating preliminary reliability and validity, which could aid clinicians and researchers.

Overview of global monitoring systems for the side effects and adverse events associated with medicinal cannabis use: a scoping review using a systematic approach

ObjectivesThe use of cannabis-based medicine (CBM) as a therapeutic has surged in Australia over the past 5 years. Historically, the United Nations Single Convention on Narcotic Drugs (1961) prohibited cannabis...

The use of medicinal cannabis as an alternative treatment for depressive disorders: integrative review

Objective: to analyze, through an integrative review, the use and applicability of medicinal cannabis as a complementary treatment in patients with depression such as unipolar disorder. Methods: the research question was “Is it effective in using medicinal cannabis as a complementary method for treating patients with depression due to unipolar disorder?”. The databases used were PubMed and Portal Capes (published between 2018-2023), with the search strategy (Depression” OR “Psychic Symptoms”) AND (“Cannabidiol” OR “Cannabis”) AND (“Young Adult” OR “Adolescent” OR “Young”). Results: there is work that supports the use of cannabis as an alternative treatment for depression; the majority, however, affirm the ineffectiveness of the compound in improving depression, with some even demonstrating its harm. Positive results ranged from 34.8% to 53% of the sample. Conclusion: there is no rigorous consensus on the benefits and harms of the medicine, and new research in the area is necessary.

California Cannabis Research Briefing, April 2023: Meeting Summary.

On April 28, 2023, the University of California Office of the President, in partnership with the California Department of Cannabis Control (DCC), hosted the California Cannabis Research Briefing. The California Cannabis Research Briefing brought together researchers and state agencies/policymakers to discuss pertinent policy issues on cannabis within the state. Researchers across six different topic areas (environment, cannabis markets, social equity matters, public health, medicinal cannabis use, and public safety) provided brief explanations of their research and its policy implications. A moderated discussion with stakeholders followed these presentations. The goals of this event were to highlight research that can inform policy issues relevant to the state, and to discuss how research can be incorporated into the cannabis policy landscape.

'The wild west of medicine': A qualitative investigation of the factors influencing Australian health-care practitioners' delivery of medicinal cannabis.

Strong patient interest in the use of medicinal cannabis to treat various clinical indications has sparked global legislative changes. Practitioners are vital in implementing regulatory changes and facilitating patient access to medicinal cannabis, however, little is currently known about the factors influencing practitioners' uptake. Recent rapid increases in practitioner applications to prescribe medicinal cannabis in Australia provides a unique backdrop to examine the current factors influencing prescribing behaviours. This qualitative study examined Australian practitioners' perspectives on prescribing medicinal cannabis to provide a comprehensive exploration of the potential factors influencing uptake in clinical practice. Seventeen semi-structured interviews were conducted with Australian health-care practitioners. Transcripts were analysed using the Framework approach to thematic analysis and cross-mapped to appropriate domains of the Theoretical Domains Framework. We identified four themes related to the barriers and facilitators to prescribing medicinal cannabis: (i) clinical capabilities needed to prescribe; (ii) prescribing an unapproved therapeutic good; (iii) negative attitudes towards prescribers in the medical community; and (iv) divergent beliefs about clinical utility. Practitioners face multiple pervasive barriers to prescribing medicinal cannabis. Beliefs about clinical utility appear to be highly influential in shaping prescribing behaviours. Moreover, our findings suggest that a medicinal cannabis 'specialisation' has emerged within the Australian medical community. Findings demonstrate that a range of complex and multifaceted factors influence practitioners' medicinal cannabis prescribing behaviours. We highlight several considerations for policy and practice to support safe and appropriate patient access to medicinal cannabis in this emerging area of clinical practice.

Increasing CB2 Receptor Activity after Early Life Stress Prevents Depressive Behavior in Female Rats.

Early adversity, the loss of the inhibitory GABAergic interneuron parvalbumin, and elevated neuroinflammation are associated with depression. Individuals with a maltreatment history initiate medicinal cannabis use earlier in life than non-maltreated individuals, suggesting self-medication. Female rats underwent maternal separation (MS) between 2 and 20 days of age to model early adversity or served as colony controls. The prelimbic cortex and behavior were examined to determine whether MS alters the cannabinoid receptor 2 (CB2), which has anti-inflammatory properties. A reduction in the CB2-associated regulatory enzyme MARCH7 leading to increased NLRP3 was observed with Western immunoblots in MS females. Immunohistochemistry with stereology quantified numbers of parvalbumin-immunoreactive cells and CB2 at 25, 40, and 100 days of age, revealing that the CB2 receptor associated with PV neurons initially increases at P25 and subsequently decreases by P40 in MS animals, with no change in controls. Confocal and triple-label microscopy suggest colocalization of these CB2 receptors to microglia wrapped around the parvalbumin neuron. Depressive-like behavior in MS animals was elevated at P40 and reduced with the CB2 agonist HU-308 or a CB2-overexpressing lentivirus microinjected into the prelimbic cortex. These results suggest that increasing CB2 expression by P40 in the prelimbic cortex prevents depressive behavior in MS female rats.

Levantamento do uso terapêutico do canabidiol por veterinários na região metropolitana de Belém do Pará

The present study aimed to analyze the knowledge of veterinarians in the metropolitan region of Belém do Pará regarding the use of Cannabis sativa for medicinal purposes in veterinary medicine. To this end, structured questionnaires were applied through the google forms platform. The data obtained were presented in percentages in order to collect information on this subject, which is of fundamental importance for the creation of dissemination strategies regarding the medicinal use of Cannabis. More than 40% of respondents claim to have gained knowledge on the matter through scientific articles and understand the importance of its integration into the clinical routine, and more than 90% believe that research on the use of medicinal Cannabis needs to be stimulated and have greater dissemination. The affirmation of the need for more studies on the use of cannabidiol in small animals is clear in the common opinion of the interviewees, including the need to utilize tools such as social media to bring this knowledge to people who can be both professionals in the area, as well as tutors who are interested in the subject.

Cannabis oil extracts for chronic pain: what else can be learned from another structured prospective cohort?

The use of medicinal cannabis for managing pain expands, although its efficacy and safety have not been fully established through randomized controlled trials. This structured, prospective questionnaire-based cohort was aimed to assess long-term effectiveness and safety of cannabis oil extracts in patients with chronic pain. Adult Israeli patients licensed to use cannabis oil extracts for chronic pain were followed prospectively for 6 months. The primary outcome measure was change from baseline in average weekly pain intensity, and secondary outcomes were changes in related symptoms and quality of life, recorded before treatment initiation and 1, 3, and 6 months thereafter. Generalized linear mixed model was used to analyze changes over time. In addition, "responders" (≥30% reduction in weekly pain at any time point) were identified. The study included 218 patients at baseline, and 188, 154, and 131 at 1, 3, and 6 months, respectively. At 6 months, the mean daily doses of cannabidiol and Δ9-tetrahydrocannabinol were 22.4 ± 24.0 mg and 20.8 ± 30.1 mg, respectively. Pain decreased from 7.9 ± 1.7 at baseline to 6.6 ± 2.2 at 6 months (F(3,450) = 26.22, P < 0.0001). Most secondary parameters also significantly improved. Of the 218 participants, 24% were "responders" but could not be identified by baseline parameters. "Responders" exhibited higher improvement in secondary outcomes. Adverse events were common but mostly nonserious. This prospective cohort demonstrated a modest overall long-term improvement in chronic pain and related symptoms and a reasonable safety profile with the use of relatively low doses of individually titrated Δ9-tetrahydrocannabinol and cannabidiol.

Stigma, risks, and benefits of medicinal cannabis use among Australians with cancer.

People with cancer who use medicinal cannabis do so despite risks associated with limited clinical evidence, legalities, and stigma. This study investigated how Australians with cancer rationalise their medicinal cannabis use despite its risks. Ten adults (5 males and 5 females; mean age of 53.3) who used cannabis medicinally for their cancer were interviewed in 2021-2022 about how they used and accessed the substance, attitudes and beliefs underpinning their use, and conversations with others about medicinal cannabis. Participants had cancer of the bowel, skin, oesophagus, stomach, thyroid, breast, and Hodgkin lymphoma for which they were receiving treatment (n = 5) or under surveillance (n = 5), with most (n = 6) encountering metastatic disease. Cannabis was used to treat a variety of cancer-related symptoms such as pain, poor sleep, and low mood. Cannabis was perceived as natural and thus less risky than pharmaceuticals. Participants legitimised their medicinal cannabis use by emphasising its natural qualities and distancing themselves from problematic users or riskier substances. Cost barriers and a lack of healthcare professional communication impeded prescription access. Similarly, participants navigated medicinal cannabis use independently due to a lack of guidance from healthcare professionals. Findings highlight the need for robust data regarding the harms and efficacy of medicinal cannabis and dissemination of such information among healthcare professionals and to patients who choose to use the substance. Ensuring healthcare professionals are equipped to provide non-judgmental and evidence-based guidance may mitigate potential safety and legal risks.

Medicinal cannabis use among young adults during California’s transition from legalized medical use to adult-use: a longitudinal analysis

ABSTRACT Background: In 2016, California transitioned from legalized medical cannabis use to adult-use. Little is known about how this policy change affected medicinal cannabis use among young adults. Objectives: To identify longitudinal groups of medicinal cannabis users and concurrent changes in health- and cannabis use-related characteristics among young adults in Los Angeles between 2014 and 2021. Methods: Cannabis users (210 patients and 156 non-patients; 34% female; ages 18–26 at baseline) were surveyed annually across six waves. Longitudinal latent class analysis derived groups from two factors – cannabis patient status and self-reported medicinal use. Trajectories of health symptoms, cannabis use motives, and cannabis use (daily/near daily use, concentrate use, and problematic use) were estimated across groups. Results: Three longitudinal latent classes emerged: Recreational Users (39.3%) – low self-reported medicinal use and low-to-decreasing patient status; Recreational Patients (40.4%) – low self-reported medicinal use and high-to-decreasing patient status; Medicinal Patients (20.3%) – high self-reported medicinal use and high-to-decreasing patient status. At baseline, Medicinal Patients had higher levels of physical health symptoms and motives than recreational groups (p < .05); both patient groups reported higher level of daily/near daily and concentrate use (p < .01). Over time, mental health symptoms increased in recreational groups (p < .05) and problematic cannabis use increased among Recreational Patients (p < .01). Conclusions: During the transition to legalized adult-use, patterns of medicinal cannabis use varied among young adults. Clinicians should monitor increases in mental health symptoms and cannabis-related problems among young adults who report recreational – but not medicinal – cannabis use.

Cannabis sativa: A therapeutic medicinal plant-global marketing updates

Cannabis has been used for thousands of years for recreational, medicinal, or religious purposes and the therapeutic potential of medicinal Cannabis was demonstrated in various medical conditions. The legalization of Cannabis is an important source of economic growth as it contributes to the growing revenue tax, and the creation of new workplaces. The maturity of the Cannabis market varies across the globe mainly due to differing legal environments and public attitudes towards Cannabis. Some countries such as Canada and the United States have adopted fully regulated frameworks that allow the cultivation, consumption, and retail distribution of various Cannabis products. Uruguay became the first country in the world to legalize the production, distribution and consumption of cannabis in 2013. The Cannabis market in Canada and the USA is experiencing rapid growth due to the country's legalization of recreational use. Regulations can also differ regarding how cannabis is used. However, the use, cultivation, and marketing of Medical Cannabis sativa (drug or Marijuana type ) is banned and prohibited in India due to the presence of high levels of psychoactive principle THC (Narcotic drug). On the other hand, Industrial Cannabis sativa (seed or fiber type) Hemp was legalized in 2021 by The Food Safety and Standards Authority of India (FSSAI), Government of India, New Delhi. In Azerbaijan, Cannabis is not available for medical or recreational use. Recreational Cannabis and medical marijuana are illegal in Azerbaijan. Marijuana is illegal for medical and recreational purposes in China. There is still a huge prejudice in society about medical Cannabis due to its recreational use. However, this scenario is changing, and the social resistance is decreasing for the medicinal use of Cannabis. The Cannabis (Hemp) market in India is predicted to experience a substantial revenue growth, with projections indicating that it will reach ₹US$100.80m by 2024. The Cannabis market worldwide is projected to reach a revenue of US$60.79bn in 2024. The global legal marijuana market size is expected to reach USD 73.6 billion by 2027 and is anticipated to expand at a CAGR of 18.1% during the forecast period.

Detection of Δ9 -tetrahydrocannabinol (THC) in oral fluid using two point-of-collection testing devices following oral administration of a THC and cannabidiolcontaining oil.

Point-of-collection testing (POCT) devices are widely used in roadside and workplace drug testing to identify recent cannabis use by measuring the presence of Δ9 -tetrahydrocannabinol (THC) in oral fluid (OF). However, the performance of POCT devices with oral medicinal cannabis products remains poorly described. In a randomised, double-blinded, crossover trial, adults with insomnia disorder (n= 20) received a single (2mL) oral dose of oil containing 10mg THC + 200 mg cannabidiol, or placebo, prior to sleep. Participants were tested with the Securetec DrugWipe® 5S (10ng/mL THC cut-off) and Dräger DrugTest® 5000 (25 ng/mL THC cut-off) POCT devices at baseline (pre-treatment) and then at 0.5, 10, and 18 h post-treatment. An OF sample, taken at each time point, was also analysed using liquid chromatography-tandem mass spectrometry. Large individual variability in OF THC concentrations was observed 0.5h post-treatment (range: 0-425 ng/mL; mean (SD) 48.7(107.5)ng/mL). Both the Securetec DrugWipe® 5S and DrugTest® 5000 demonstrated poor sensitivity to THC at 0.5h post-treatment (25% and 50%, respectively). At 10 and 18 h post-treatment, all participant OF THC concentrations were below screening cut-offs, and all test results were negative. These findings highlight the relatively poor sensitivity of both devices in detecting recent use of an oral medicinal cannabis product. They also suggest a low probability of obtaining a positive THC result the morning after ('one-off') use. Further research is required to establish the probability of obtaining a positive THC result with regular medicinal cannabis use.

Patterns of cannabis use, perception of harm, and perceived impact of legislative change in an online sample of young adults from Lebanon: insight on recreational users versus dual motive users

BackgroundLebanon remains as one of the major sources of cannabis worldwide. In 2020, its government passed a legislation enabling the cultivation of local medicinal cannabis. This first study following the legislative change examines the overlapping use of cannabis for recreational/medicinal purposes and characteristics of the distinct cannabis user types.MethodsA total of 1230 young adults (18–24 years) filled an anonymous online survey in early 2020.ResultsYoung adults in the sample were distributed as follows: 33% 18–20 years; 60% males; 94% Lebanese; 75% students; and 89% living with family. The older young adults (21–24), males, those employed, living with non-family members, and who perceived themselves as being a little/lot richer than most were statistically significantly more present in the cannabis user subtypes (recreational only or recreational/medicinal) than non-cannabis users. When dual recreational/medicinal users are compared to recreational users only, the latter seemed to have a more conservative profile of behaviours, attitudes, and perceptions and acts of harm. The prevalence ratio comparing the prevalence of users supporting consuming cannabis “once or twice” in dual motive users vs. recreational users only was 1.13 for “once or twice”, 1.25 for “occasionally”, 1.64 for “regularly”, and 2.4 for “daily”. Any other illicit drug use was reported by 1% of the non-cannabis users, 36% of the recreational users only, and 58% of the recreational/medicinal users (p-value < 0.01). Similarly, any prescription drug use was reported by 3% of the non-cannabis users, 16% of the recreational users only, and 28% of both recreational/medicinal users (p-value < 0.01).ConclusionThe interface between recreational and medicinal cannabis use is complex. Dual motive users may warrant special attention as a subpopulation of cannabis users. This is relevant to contexts experiencing medicinal cannabis legislation changes, such as Lebanon, as policymakers and implementers should be sensitized to the emerging evidence for more data-informed policy changes.

Differences in prescribed medicinal cannabis use by cannabinoid product composition: Findings from the cannabis as medicine survey 2020 (CAMS-20) Australia-wide study.

Prescribed medicinal cannabis (MC) is an increasingly common prescription in Australia for treating pain, anxiety, and sleep disorders. Prescribed MC products generally contain tetrahydrocannabinol (THC) and/or cannabidiol (CBD) in a variety of dose levels and forms. It is unclear whether THC and CBD products are used by patients with different characteristics and for different conditions. To examine consumer experiences of using THC- and CBD-containing prescribed MC products to better understand how they are being used within the Australian context. We utilised data collected from an online anonymous cross-sectional survey of individuals (CAMS-20 survey), consisting of Australian residents using cannabis for therapeutic reasons. We focused on a subgroup of participants (N = 546) receiving prescribed MC products. We utilised linear, logistic, and multinomial regression modelling to analyse responses to survey questions based on the cannabinoid profile of the prescribed product. Participants prescribed THC-dominant MC products were statistically more likely to be younger, male, and to prefer inhaled routes of administration than participants using CBD-dominant products who were older, female, and preferred oral routes of administration. Pain and mental health were the most common reasons for all types of prescribed MC, but were more likely to be treated with THC than CBD despite the significantly higher risk of mild to severe drowsiness, dry mouth and eye irritation. Consumer reported effectiveness of prescribed MC was very positive, particularly for THC-containing products. Consumers on opioids and antipsychotics were statistically more likely to be prescribed THC-containing products than products containing CBD only, despite the greater risk of impairment. This Australia-wide study found clear differences in consumer-reported experiences of prescribed THC- and CBD-containing products. Current prescriptions of these products do not always align with relevant clinical guidance. Educating prescribers around cannabinoid products is essential to ensure optimal prescribing practices and to prevent avoidable drug side effects and interactions.

Got the Munchies for an Egg Sandwich? The Effects of Cannabis on Bowel Motility and Beyond.

The use of medicinal cannabis has a long history dating back thousands of years. Recent discoveries have shed light on its mechanism of action with the identification of cannabinoid receptors and endocannabinoids, which make up the body's endocannabinoid system. Cannabinoid receptors, particularly the cannabinoid 1 and 2 receptors, play a crucial role in modulating the gut-brain axis and serve as potential therapeutic targets for gastrointestinal motility and inflammatory disorders. With increasing legalization of cannabis and a rising number of users, understanding the effects of cannabis on gut motility is essential for nuclear medicine providers. Although tetrahydrocannabinol, the principal psychoactive constituent of cannabis, may decrease gut motility in experimental settings, it appears to paradoxically improve symptoms in gastroparesis. Treatment effects are difficult to measure given the large number of variables that could significantly alter outcomes, such as cannabinoid type, potency, and route of intake. Another consideration is the highly personalized gut microbiome, which directly interacts with the endocannabinoid system. Further research is required to delineate these multifaceted, complex cannabinoid interactions. The goal of this article is to explore the knowns and unknowns of the impact of cannabis on the alimentary system.
