Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Chinese herbal medicine is increasingly used as complementary therapy to manage nausea and vomiting in different cultures. One such herbal recipe is the Hezhong granules, which contain classical antiemetic formulations, and are commonly used to prevent chemotherapy-induced nausea and vomiting (CINV). Modern pharmacological studies have shown that the key components of Hezhong granules, including Pinellia ternata (Thunb.), Evodia rutaecarpa (Juss.), and Zingiber officinale exhibit significant antiemetic and antitumor properties. Despite this promising evidence, controlling CINV remains a significant challenge in cancer treatment. Moreover, there is a lack of scientifically designed clinical trials to validate the efficacy and safety of classical antiemetic formulas for CINV interventions. AIMS OF THE STUDY To investigate the efficacy and safety of Hezhong granules in preventing CINV in patients with advanced colorectal cancer (CRC). METHODS This study was conducted between October 2020 and February 2022 in 12 hospital wards in Southwest China. In this multicenter, randomized controlled trial, we enrolled patients with advanced CRC who received fluorouracil-based chemotherapy. The patients were randomly assigned in a 1:1 ratio to either the Hezhong granule group (receiving a 5-HT3-receptor antagonist, dexamethasone, and Hezhong granules) or the placebo group (receiving a 5-HT3-receptor antagonist, dexamethasone, and placebo) during the first and second courses of chemotherapy. A 5-day diary was provided to all patients. Acute and delayed CINV were defined as CINV occurring within 24 h or between 24 and 120 h after the start of treatment. The primary endpoints were complete response rate (CRR, defined as the proportion of patients without nausea/vomiting) and objective response rate (ORR, defined as the proportion of patients without nausea/vomiting plus mild nausea/vomiting) for both acute and delayed CINV. Secondary endpoints were the daily rates of CINV events and Functional Living Index-Emesis (FLIE). To identify the predictors of CINV, we conducted multivariate ordered logistic regression analysis. This study was registered with the Chinese Clinical Trial, number ChiCTR2100041643. RESULTS A total of 120 participants were randomly assigned, of whom 112 (56/56) completed two cycles and were included in the full analysis. In the acute phase, there were minor improvements in the Hezhong granule group, but there were no significant differences in the CRRs for nausea and vomiting (mean difference:10.7 %, P = 0.318, 0.324), while the ORRs increased by approximately 17.5 % (mean difference:16.1 %, P = 0.051; 17.9 %, P = 0.037, respectively). In the delayed phase, significant improvements of approximately 20 % were observed in both the CRRs (mean difference:19.6 %, P = 0.053; 21.4 %, P = 0.035) and ORRs (mean difference:17.9 %, P = 0.037, 0.043) for nausea and vomiting. Additionally, the daily rate of CINV events showed a mean difference of 19 % (P < 0.05). According to FLIE scores, approximately 70 % of patients who received Hezhong granules reported an improvement in their quality of life, with CINV symptoms having"no impact on daily life (NIDL)". No serious adverse events were attributed to herbal medicine. CONCLUSIONS Hezhong granules proved to be both effective and well-tolerated in preventing CINV in patients with advanced CRC, with notable benefits in preventing delayed CINV. These promising results set the stage for subsequent phase III clinical trials and experimental research on Hezhong Granules.

Abstract
PURPOSE To guide clinicians, adults with cancer, caregivers, researchers, and oncology institutions on the medical use of cannabis and cannabinoids, including synthetic cannabinoids and herbal cannabis derivatives; single, purified cannabinoids; combinations of cannabis ingredients; and full-spectrum cannabis. METHODS A systematic literature review identified systematic reviews, randomized controlled trials (RCTs), and cohort studies on the efficacy and safety of cannabis and cannabinoids when used by adults with cancer. Outcomes of interest included antineoplastic effects, cancer treatment toxicity, symptoms, and quality of life. PubMed and the Cochrane Library were searched from database inception to January 27, 2023. ASCO convened an Expert Panel to review the evidence and formulate recommendations. RESULTS The evidence base consisted of 13 systematic reviews and five additional primary studies (four RCTs and one cohort study). The certainty of evidence for most outcomes was low or very low. RECOMMENDATIONS Cannabis and/or cannabinoid access and use by adults with cancer has outpaced the science supporting their clinical use. This guideline provides strategies for open, nonjudgmental communication between clinicians and adults with cancer about the use of cannabis and/or cannabinoids. Clinicians should recommend against using cannabis or cannabinoids as a cancer-directed treatment unless within the context of a clinical trial. Cannabis and/or cannabinoids may improve refractory, chemotherapy-induced nausea and vomiting when added to guideline-concordant antiemetic regimens. Whether cannabis and/or cannabinoids can improve other supportive care outcomes remains uncertain. This guideline also highlights the critical need for more cannabis and/or cannabinoid research.Additional information is available at www.asco.org/supportive-care-guidelines.

Abstract
OBJECTIVE Recreational cannabis legalization (RCL) is expanding rapidly. RCL's effects on mental health issues are of particular concern because cannabis use is more frequent among people receiving psychiatric care and is associated with several psychiatric disorders. The authors conducted a scoping review to examine the evidence and discern gaps in the literature concerning the effects of RCL on mental health and to assess the factors responsible for an observed heterogeneity in research results. METHODS This scoping literature review followed PRISMA guidelines. Five databases-MEDLINE, CINAHL, Embase, APA PsycInfo, and Web of Science-were searched for English- or French-language reports published between January 1, 2012, and April 30, 2023. RESULTS Twenty-eight studies from the United States and Canada were found. The studies were classified by category of the study's data (patients receiving psychiatric care [k=1], death records [k=4], emergency department or hospital records [k=10], and the general population [k=13]) and by the diagnosis (schizophrenia or psychoses, mood disorders, anxiety disorders and symptoms, suicide or suicidal ideation, or other mental health issues) examined. The review findings revealed a paucity of research and indicated mixed and largely inconclusive results of the studies examined. Research gaps were found in the examination of potential changes in cannabis use patterns among people receiving psychiatric care and in the availability of longitudinal studies. CONCLUSIONS Clinicians, researchers, and policy makers need to collaborate to address the research gaps and to develop evidence-based policies that reflect a thorough understanding of the effects associated with RCL.

Abstract
In this review, we discuss the potential role of cannabis and cannabinoids in the management of cancer-related symptoms. There is limited evidence demonstrating the effectiveness of cannabis-based products in treating cancer-related pain and gastrointestinal symptoms such as nausea, vomiting, and loss of appetite. Regarding the role of cannabis-based products in the treatment of insomnia and mood disorders, most studies looked at these symptoms as secondary outcomes with mixed results. Cannabis-based products have adverse effects, ranging from neuropsychiatric to systemic effects to potential drug interactions.

Abstract
INTRODUCTION The non-intoxicating plant-derived cannabinoid, cannabidiol (CBD), has demonstrated therapeutic potential in a number of clinical conditions. Most successful clinical trials have used relatively high (≥300 mg) oral doses of CBD. Relatively few studies have investigated the efficacy of lower (<300 mg) oral doses, typical of those available in over-the-counter CBD products. METHODS We present a protocol for a randomised, double-blind, placebo-controlled, parallel-group clinical trial investigating the effects of a low oral dose (150 mg) of CBD on acute psychosocial stress, situational anxiety, motion sickness and cybersickness in healthy individuals. Participants (n=74) will receive 150 mg of CBD or a matched placebo 90 min before completing three virtual reality (VR) challenges (tasks) designed to induce transient stress and motion sickness: (a) a 15 min 'Public Speaking' task; (b) a 5 min 'Walk the Plank' task (above a sheer drop); and (c) a 5 min 'Rollercoaster Ride' task. The primary outcomes will be self-reported stress and nausea measured on 100 mm Visual Analogue Scales. Secondary outcomes will include salivary cortisol concentrations, skin conductance, heart rate and vomiting episodes (if any). Statistical analyses will test the hypothesis that CBD reduces nausea and attenuates subjective, endocrine and physiological responses to stress compared with placebo. This study will indicate whether low-dose oral CBD has positive effects in reducing acute psychosocial stress, situational anxiety, motion sickness and cybersickness. ETHICS AND DISSEMINATION The University of Sydney Human Research Ethics Committee has granted approval (2023/307, version 1.6, 16 February 2024). Study findings will be disseminated in a peer-reviewed journal and at academic conferences. TRIAL REGISTRATION NUMBER Australian New Zealand Clinical Trials Registry (ACTRN12623000872639).

Abstract
BACKGROUND Natural and synthetic cannabinoids are being used worldwide to treat various symptoms in cancer patients. This study aims to map the therapeutic benefits and adverse effects associated with the use of cannabis-based drugs in these outcomes. METHODS Following Joanna Briggs Institute guidelines a scoping review was conducted. The study protocol was available in the Open Science Framework public repository. An extensive search strategy involving databases like Cochrane Library, Embase, CINAHL, Medline/PubMed, Lilacs, Google Scholar, and Open Gray for gray literature analysis was executed by a skilled librarian. The inclusion criteria were primary studies (observational and randomized) that evaluated the efficacy and safety of cannabinoids in cancer patients. The review encompassed studies of diverse designs, publication years, and types, as long as they addressed cannabinoids' impact in oncology. RESULTS Twenty-nine (82.86%) out of total of 35 were randomized and 6 (14.14%) were non-randomized. About 57.1% of studies utilized registered products as interventions, with THC being the most natural cannabinoid cited in variable doses and administration routes. Moreover, 62.85% of studies specified the cancer types (breast, lung, sarcomas, hematological and reproductive system), while only one study detailed cancer staging. The evaluated outcomes encompassed nausea and vomiting (77.14%), appetite (11.43%), pain (8.57%), and tumor regression (2.86%) across different proportions of studies. CONCLUSION Cannabinoids show promise in managing pain, emesis, and anorexia/cachexia linked to cancer progression. New randomized clinical trials with a larger number of participants and observational studies on long-term safety are crucial to affirm their medicinal utility for cancer patients unresponsive to conventional drugs.

Abstract
To test the hypothesis that genetic and pharmacological modulation of the classical cannabinoid type 1 (CB1) and 2 (CB2) receptors attenuate cancer-induced bone pain, we searched Medline, Web of Science and Scopus for relevant skeletal and non-skeletal cancer studies from inception to July 28, 2022. We identified 29 animal and 35 human studies. In mice, a meta-analysis of pooled studies showed that treatment of osteolysis-bearing males with the endocannabinoids AEA and 2-AG (mean difference [MD] - 24.83, 95% confidence interval [95%CI] - 34.89, - 14.76, p < 0.00001) or the synthetic cannabinoid (CB) agonists ACPA, WIN55,212-2, CP55,940 (CB1/2-non-selective) and AM1241 (CB2-selective) (MD - 28.73, 95%CI - 45.43, - 12.02, p = 0.0008) are associated with significant reduction in paw withdrawal frequency. Consistently, the synthetic agonists AM1241 and JWH015 (CB2-selective) increased paw withdrawal threshold (MD 0.89, 95%CI 0.79, 0.99, p < 0.00001), and ACEA (CB1-selective), AM1241 and JWH015 (CB2-selective) reduced spontaneous flinches (MD - 4.85, 95%CI - 6.74, - 2.96, p < 0. 00001) in osteolysis-bearing male mice. In rats, significant increase in paw withdrawal threshold is associated with the administration of ACEA and WIN55,212-2 (CB1/2-non-selective), JWH015 and AM1241 (CB2-selective) in osteolysis-bearing females (MD 8.18, 95%CI 6.14, 10.21, p < 0.00001), and treatment with AM1241 (CB2-selective) increased paw withdrawal thermal latency in males (mean difference [MD]: 3.94, 95%CI 2.13, 5.75, p < 0.0001), confirming the analgesic capabilities of CB1/2 ligands in rodents. In human, treatment of cancer patients with medical cannabis (standardized MD - 0.19, 95%CI - 0.35, - 0.02, p = 0.03) and the plant-derived delta-9-THC (20 mg) (MD 3.29, CI 2.24, 4.33, p < 0.00001) or its synthetic derivative NIB (4 mg) (MD 2.55, 95%CI 1.58, 3.51, p < 0.00001) are associated with reduction in pain intensity. Bioinformatics validation of KEGG, GO and MPO pathway, function and process enrichment analysis of mouse, rat and human data revealed that CB1 and CB2 receptors are enriched in a cocktail of nociceptive and sensory perception, inflammatory, immune-modulatory, and cancer pathways. Thus, we cautiously conclude that pharmacological modulators of CB1/2 receptors show promise in the treatment of cancer-induced bone pain, however further assessment of their effects on bone pain in genetically engineered animal models and cancer patients is warranted.

Abstract
PURPOSE Limited studies have described the utilization of cannabinoids among patients with cancer. This survey study aimed to characterize utilization patterns and perceptions of cannabinoid use for treatment-related side effects among patients receiving radiation treatment. METHODS AND MATERIALS This was an anonymous survey study of patients who were undergoing or recently completed radiation treatment at a comprehensive cancer center. Data on cannabinoid use during cancer treatment, reasons for the use of cannabinoids, perceived effects of cannabinoids, and formulations of usage were collected and summarized using descriptive statistics. RESULTS Of the 431 respondents, 111 (25.8%) patients reported cannabinoid use since their cancer diagnosis. Among the cannabinoid users, a majority (73.9%) experienced improvement in symptoms; 38.7% had better relief of cancer-treatment symptoms from cannabinoids in comparison to their prescription medications, and 16.2% lowered the amount of prescription pain medications needed after using cannabinoids. Cannabinoids appeared to be most effective in helping patients manage sleep (76.6%) and anxiety (72.1%). When asked about whether physicians should be discussing cannabinoid use, 45.1% of cannabinoid users wanted to speak with their doctors regarding its utilization. For patients who did not report cannabinoid use, a large majority (83.1%) never had discussions with their doctors regarding its utilization as part of their cancer care, and 34.8% wanted to learn more about cannabinoids from their doctors. CONCLUSIONS About 1 in 4 patients with cancer reported cannabinoid use to assist in symptom control. A majority had subjective alleviation of treatment-related symptoms from cannabinoid use. Regardless of cannabinoid use, a sizable percentage of patients never had any discussions about cannabinoids with their oncologists, with some expressing interest in learning more. Guidelines are needed to assist radiation oncologists on how cannabinoids may play a role in caring for patients.

Abstract
The side effects of cancer therapy continue to cause significant health and cost burden to the patient, their friends and family, and governments. A major barrier in the way in which these side effects are managed is the highly siloed mentality that results in a fragmented approach to symptom control. Increasingly, it is appreciated that many symptoms are manifestations of common underlying pathobiology, with changes in the gastrointestinal environment a key driver for many symptom sequelae. Breakdown of the mucosal barrier (mucositis) is a common and early side effect of many anti-cancer agents, known to contribute (in part) to a range of highly burdensome symptoms such as diarrhoea, nausea, vomiting, infection, malnutrition, fatigue, depression, and insomnia. Here, we outline a rationale for how, based on its already documented effects on the gastrointestinal microenvironment, medicinal cannabis could be used to control mucositis and prevent the constellation of symptoms with which it is associated.

Abstract
Cannabis has been used as an herbal remedy for thousands of years, and recent research indicates promising new uses in medicine. So far, some studies have shown cannabinoids to be safe in helping mitigate some cancer-associated complications, including chemotherapy-induced nausea and vomiting, cancer-associated pain, and tumor growth. Researchers have been particularly interested in the potential uses of cannabinoids in treating cancer due to their ability to regulate cancer-related cell cycle pathways, prompting many beneficial effects, such as tumor growth prevention, cell cycle obstruction, and cell death. Cannabinoids have been found to affect tumors of the brain, prostate, colon and rectum, breast, uterus, cervix, thyroid, skin, pancreas, and lymph. However, the full potential of cannabinoids is yet to be understood. This review discusses current knowledge on the promising applications of cannabinoids in treating three different side effects of cancer-chemotherapy-induced nausea and vomiting, cancer-associated pain, and tumor development. The findings suggest that cannabinoids can be used to address some side effects of cancer and to limit the growth of tumors, though a lack of supporting clinical trials presents a challenge for use on actual patients. An additional challenge will be examining whether any of the over one hundred naturally occurring cannabinoids or dozens of synthetic compounds also exhibit useful clinical properties. Currently, clinical trials are underway; however, no regulatory agencies have approved cannabinoid use for any cancer symptoms beyond antinausea.

Abstract
Introduction: Cancer patients report nausea as a side effect of their chemotherapy treatment. Using the pre-clinical rodent model of acute nausea-lithium chloride (LiCl)-induced conditioned gaping-our group has demonstrated that exogenous cannabinoids may have antinausea potential. Materials and Methods: With the goal of evaluating the role of sex as a factor in pre-clinical research, we first compared the conditioned gaping reactions produced by varying doses of LiCl in male and female rats using the taste reactivity test (Experiment 1). Results: LiCl produced dose-dependent conditioned gaping similarly in male and female rats with the highest dose (127.2 mg/kg) producing robust conditioned gaping, with this dose used in subsequent experiments. Next, we examined the antinausea potential of THC (Experiment 2), CBD (Experiment 3), cannabidiolic acid (CBDA; Experiment 4) and oleoyl alanine (OlAla; Experiment 5) in both male and female rats. THC, CBD, CBDA, and OlAla dose dependently reduced conditioned gaping in both male and female rats in a similar manner. Conclusions: These results suggest that cannabinoids may be equally effective in treating nausea in both males and females.

Abstract
In 2016, the Australian Government legislated to allow cannabis to be prescribed to patients as an unapproved medicine under the special access provisions of the Therapeutic Goods Act. This paper compares the Australian regulatory approach with other national approaches, outlines the main provisions of the Special Access Scheme for medical cannabis, describes how the program has evolved since 2017, includes an analysis of adverse events reported to the Therapeutic Goods Administration, and discusses the barriers that remain for patients who wish to access medical cannabis. It assesses how well the Australian program has addressed the challenges of providing patients with easier access to medical cannabis while ensuring that high-quality products are used safely and effectively under medical guidance.

Abstract
BACKGROUND A minority of oncologists feel qualified to advise adults with cancer on issues pertaining to medicinal cannabis. Adults with cancer frequently access medicinal cannabis information from non-medical sources such as cannabis dispensaries. We explored dispensary personnel's views and experiences regarding oncologic cannabis and the counsel they extend individuals with cancer. METHODS Snowball sampling in this qualitative study facilitated recruitment across 13 states (N = 26). Semi-structured phone interviews ceased with thematic saturation. A multi-stage thematic analysis combined inductive and deductive codes. RESULTS Of the 26 dispensary personnel interviewed, 54% identified as female and 19% as non-white. Median age was 40 years. A consensus emerged among participants concerning the botanical's efficacy for cancer-related symptoms; less so regarding its antineoplastic potential. Principles for serving those with cancer included provision of client-centered, symptom-based, and trial-and-error approaches. Non-inhalation modes of administration were generally recommended. No consensus was reached as to whether delta-9-tetrahydrocannabinal (THC)- or cannabidiol-predominant products were preferable in this population. Challenges in oncologic advising included successfully identifying individuals with cancer at the dispensary counter, financial toxicity, the special treatment required for the THC-naïve, and operating in the absence of standardized guidelines. CONCLUSIONS These informed assertions suggest that members of the oncologic community should grapple with the extent to which they feel comfortable with both the nature and degree of counsel adults with cancer receive through dispensaries.

Abstract
Chemotherapy-induced nausea and vomiting (CINV) and radiotherapy-induced nausea and vomiting (RINV) strongly affect the quality of life of patients with cancer. Inadequate antiemetic control leads to the decline of patients' quality of life, increases rescue interventions, and may even compromise adherence to cancer treatment. Although there are international recommendations for controlling CINV and RINV, these recommendations focus mainly on pharmacological management, with scarce information on additional measures that patients may adopt. Moreover, the prophylaxis and management of CINV/RINV are not always applied. Thus, we identified the need to systematize the strategies for preventing and managing CINV/RINV and the associated risk factors to implement and promote effective prophylactic antiemetic regimens therapy in patients with cancer. This review sought to create a set of practical recommendations for managing and controlling CINV/RINV, according to the current international recommendations for antiemetic therapy and the main risk factors. Conclusively, we intended to produce a patient-centered guidance document for health care professionals focused on the awareness, monitoring, and treatment of CINV/RINV.

Abstract
Objective To evaluate the effects of tetrahydrocannabinol (THC):cannabinoid (CBD) (1:1) oil in reducing chemotherapy-induced nausea and vomiting (CINV) in gynecologic cancer patients who received moderate-to-high emetogenic chemotherapy. Material and Method This was a randomized, double-blinded, crossover and placebo-controlled trial. The study was conducted at the Gynecologic Oncology Units, Bhumibol Adulyadej Hospital (BAH), Royal Thai Air Force, Bangkok, Thailand, between August and November 2022. Participants had gynecologic cancer and received moderate-to-high emetogenic chemotherapy. Subjects were randomized and divided into two groups (A and B) based on the block of four randomization method. In the first cycle, groups A and B received THC:CBD extract oil 1:1 (TCEO) and placebo before chemotherapy administration. In the second cycle, groups A and B received placebo and TCEO before chemotherapy administration. Both groups received per protocol antiemetic medication during chemotherapy. Nausea score and side effects were recorded. Results A total of 60 cases were recruited. After exclusion, 54 cases were included in the study. The mean age of participants was 54.4 years. The mean body mass index (BMI) was 26.5 kg/m2. Fifty-nine (21/54) percent cases were the advanced stages of cancer. The nausea score of TCEO and placebo groups were 2.11 and 2.99, respectively (P < 0.05). More than half of the participants (36/54) reported dizziness and sedation side effects. Dry mouth, confusion, anxiety, and palpitation of both groups were comparable. Conclusion The cannabinoid extract (THC:CBD) was an appropriate adjuvant agent to reduce CINV in patients with gynecologic cancer who received high-emetogenic chemotherapy. Dizziness and sedation were the major side effects.

Abstract
Cannabis enjoyed a "golden age" as a medicinal product in the late 19th, early 20th century, but the increased risk of overdose and abuse led to its criminalization. However, the 21st century have witnessed a resurgence of interest and a large body of literature regarding the benefits of cannabinoids have emerged. As legalization and decriminalization have spread around the world, cancer patients are increasingly interested in the potential utility of cannabinoids. Although eager to discuss cannabis use with their oncologist, patients often find them to be reluctant, mainly because clinicians are still not convinced by the existing evidence-based data to guide their treatment plans. Physicians should prescribe cannabis only if a careful explanation can be provided and follow up response evaluation ensured, making it mandatory for them to be up to date with the positive and also negative aspects of the cannabis in the case of cancer patients. Consequently, this article aims to bring some clarifications to clinicians regarding the sometimes-confusing various nomenclature under which this plant is mentioned, current legislation and the existing evidence (both preclinical and clinical) for the utility of cannabinoids in cancer patients, for either palliation of the associated symptoms or even the potential antitumor effects that cannabinoids may have.

Abstract
Cannabis-derived therapies are gaining popularity in the medical world. More and more perfect forms of cannabinoids are sought, which could be used in the treatment of many common diseases, including metabolic syndrome, whose occurrence is also increasing. The purpose of this review was to investigate the usefulness of cannabinoids, mainly cannabidiol (CBD), in individuals with obesity, impaired glucose and lipid metabolism, high blood pressure, and non-alcoholic fatty liver disease (NAFLD). We summarised the most recent research on the broad topic of cannabis-derived influence on metabolic syndrome components. Since there is a lot of work on the effects of Δ9-THC (Δ9-tetrahydrocannabinol) on metabolism and far less on cannabidiol, we felt it needed to be sorted out and summarised in this review. The research results on the use of cannabidiol in obesity are contraindicatory. When it comes to glucose homeostasis, it appears that CBD maintains it, sensitises adipose tissue to insulin, and reduces fasting glucose levels, so it seems to be a potential target in this kind of metabolic disorder, but some research results are inconclusive. CBD shows some promising results in the treatment of various lipid disorders. Some studies have proven its positive effect by decreasing LDL and increasing HDL as well. Despite their probable efficacy, CBD and its derivatives will likely remain an adjunctive treatment rather than a mainstay of therapy. Studies have also shown that CBD in patients with hypertension has positive effects, even though the hypotensive properties of cannabidiol are small. However, CBD can be used to prevent blood pressure surges, stabilise them, and have a protective effect on blood vessels. Results from preclinical studies have shown that the effect of cannabidiol on NAFLD may be potentially beneficial in the treatment of the metabolic syndrome and its components. Nevertheless, there is limited data on CBD and NAFLD in human studies. Because of the numerous confounding factors, the conclusions are unclear, and more research in this field is required.

Abstract
Colorectal tumors often create an immunosuppressive microenvironment that prevents them from responding to immunotherapy. Cannabidiol (CBD) is a non-psychoactive natural active ingredient from the cannabis plant that has various pharmacological effects, including neuroprotective, antiemetic, anti-inflammatory, and antineoplastic activities. This study aimed to elucidate the specific anticancer mechanism of CBD by single-cell RNA sequencing (scRNA-seq) and single-cell ATAC sequencing (scATAC-seq) technologies. Here, we report that CBD inhibits colorectal cancer progression by modulating the suppressive tumor microenvironment (TME). Our single-cell transcriptome and ATAC sequencing results showed that CBD suppressed M2-like macrophages and promoted M1-like macrophages in tumors both in strength and quantity. Furthermore, CBD significantly enhanced the interaction between M1-like macrophages and tumor cells and restored the intrinsic anti-tumor properties of macrophages, thereby preventing tumor progression. Mechanistically, CBD altered the metabolic pattern of macrophages and related anti-tumor signaling pathways. We found that CBD inhibited the alternative activation of macrophages and shifted the metabolic process from oxidative phosphorylation and fatty acid oxidation to glycolysis by inhibiting the phosphatidylinositol 3-kinase-protein kinase B signaling pathway and related downstream target genes. Furthermore, CBD-mediated macrophage plasticity enhanced the response to anti-programmed cell death protein-1 (PD-1) immunotherapy in xenografted mice. Taken together, we provide new insights into the anti-tumor effects of CBD.

Abstract
Cannabis, commonly known as marijuana, is a drug extracted from the Cannabis plant known for its psychotropic and medicinal properties. It has been used for healing purposes during ancient times, although its psychoactive components led to its restricted use in medicine. Nonetheless, cannabis is found to have modulatory effects on the endocannabinoid system exhibiting its medicinal role in the gastrointestinal (GI) system. Emerging animal and human studies demonstrate the influential effects of cannabis on a variety of GI diseases including inflammatory bowel disease, motility disorders and GI malignancies. It also has a regulatory role in GI symptoms including nausea and vomiting, anorexia, weight gain, abdominal pain, among others. However, both its acute and chronic use can lead to undesirable side effects such as dependency and addiction, cognitive impairment and cannabinoid hyperemesis syndrome. We will discuss the role of cannabis in the GI system as well as dosing strategies to help guide gastroenterologists to assess its efficacy and provide patient counseling before prescription of medical marijuana.

Abstract
Purpose of review Substance use disorders are becoming increasingly prevalent in the geriatric population, necessitating an updated understanding of the existing literature. This review aims to describe the epidemiology, special considerations, and management of substance use disorders in older adults. Recent findings PubMed, Ovid MEDLINE, and PsychINFO databases were searched from their inception through June 2022 using the following keywords: "substance use disorder," "substance abuse," "abuse," "illicit substances," "illicit drugs," "addiction," "geriatric," "elderly," "older adults," "alcohol," "marijuana," "cannabis," "cocaine," "heroin," "opioid," and "benzodiazepine." Our findings suggest an increasing trend in substance use in older adults despite medical and psychiatric consequences when using such substances. The majority of older patients admitted to substance abuse treatment programs were not referred by healthcare providers, suggesting room for improvement in the screening and discussion of substance use disorders. Our review also suggests that there should be careful consideration of COVID-19 and racial disparities when screening, diagnosing, and treating substance use disorders in the older population. Summary This review provides updated information on epidemiology, special considerations, and management of substance use disorders in older adults. As substance use disorders become more prevalent in older adults, primary care physicians must be prepared to recognize and diagnose substance use disorders as well as collaborate with and refer patients to geriatric medicine, geriatric psychiatry, and addiction medicine.

Abstract
Chemotherapy-induced nausea and the subsequent vomiting (CINV) are adverse effects of cancer treatment associated with considerable burden for the patient. CINV has a significant negative impact on quality of life. The consequent loss of fluids and electrolytes can lead to impaired renal function or weight loss, which may lead to hospitalization. If CINV later results in anticipatory vomiting, this complicates both CINV prophylaxis and further chemotherapy, which can endanger the continuation of cancer treatment. The introduction of high-dose dexamethasone as well as 5‑HT3 and NK1 receptor antagonists has led to a significant improvement of CINV prophylaxis since the 1990s. Recommendations on CINV prophylaxis are in available in guidelines. Adherence to these guidelines results in better outcomes.

Abstract
There have been significant advances in the treatment of cancer in the past decade. However, patients continue to suffer from significant side effects of antineoplastic agents that greatly affect their quality of life (QOL), including chemotherapy-induced nausea and vomiting (CINV), chemotherapy-induced peripheral neuropathy (CIPN), and chemotherapy-induced alopecia (CIA). This review aims to provide an updated overview of emerging strategies for the management and prevention of these immediate and long-lasting side effects. The use of integrative medicine including cannabis continues to evolve in the realm of CINV and cancer-related anorexia. Although no pharmaceutical agent has been approved for the prevention of CIPN, cryotherapy, compression therapy and, more recently, cryocompression therapy have shown benefit in small trials, but there are concerns with tolerability especially related to cryotherapy. More data are necessary to determine an effective and tolerable option to prevent CIPN in large, randomized studies. Scalp cooling (SC), which has a similar mechanism to cryotherapy and compression therapy for CIPN prevention, has proven to be an effective and tolerable approach in randomized studies and has significantly limited CIA, an entity that definitively affects the QOL of patients living with cancer. Taken together, cannabis, cryotherapy, compression and cryocompression therapy, and SC all strive to improve the QOL of patients living with cancer by minimizing the side effects of chemotherapeutic agents.

Abstract
Objective The primary objective of this study was to estimate the prevalence of cannabis use in patients with gynecologic malignancies and to describe patterns of cannabis use. Secondary objectives included identifying sources of cannabis information used by patients. Methods This is a single institution cross sectional survey conducted in Calgary, Alberta. Patients with a current or prior gynecologic cancer diagnosis were considered for inclusion. Planned analysis included descriptive statistics of patient demographics, and the patterns of cannabis use were described using frequencies and proportions. Results Forty-six patients participated in the survey. The most common disease sites were ovarian cancer and uterine cancer, with the majority of patients receiving chemotherapy as part of their treatment (n = 35). Seventeen participants were current cannabis users (37%). The most common symptoms participants used cannabis for were pain (9/17), anxiety (9/17), and insomnia (9/17).Most patients using cannabis did not have a prescription and obtained their cannabis from a recreational dispensary (11/17). Many participants using cannabis had not talked to their doctor about cannabis (9/17). Instead, the most common sources of information about cannabis were cannabis retailers (20/46), and friends/family (20/46). Over 50% of patients would be interested in discussing cannabis if their physician broached the subject (26/46). Conclusions The results from this survey indicate that patients would like to talk to their oncologist about cannabis. Further research is needed to inform physician training and direct patient education to ensure that patients have access to unbiased, evidence-based information to make decisions about cannabis use.

Abstract
Supercritical carbon dioxide (CO2) extraction techniques meet all-new consumer market demands for health-promoting phytochemical compound-rich extracts produced from green and sustainable technology. In this regard, this review is dedicated to discussing is the promise of integrating high-pressure CO2 technologies into the Cannabis sativa L. processing chain to valorize its valuable pharmaceutical properties and food biomass. To do this, the cannabis plant, cannabinoids, and endocannabinoid system were reviewed to understand their therapeutic and side effects. The supercritical fluid extraction (SFE) technique was presented as a smart alternative to producing cannabis bioproducts. The impact of SFE operating conditions on cannabis compound extraction was examined for aerial parts (inflorescences, stems, and leaves), seeds, and byproducts. Furthermore, the opportunities of using non-thermal supercritical CO2 processing on cannabis biomass were addressed for industrial hemp valorization, focusing on its biorefinery to simultaneously produce cannabidiol and new ingredients for food applications as plant-based products.

Abstract
The application of cannabis products in oncology receives interest, especially from patients. Despite the plethora of research data available, the added value in curative or palliative cancer care and the possible risks involved are insufficiently proven and therefore a matter of debate. We aim to give a recommendation on the position of cannabis products in clinical oncology by assessing recent literature. Various types of cannabis products, characteristics, quality and pharmacology are discussed. Standardisation is essential for reliable and reproducible quality. The oromucosal/sublingual route of administration is preferred over inhalation and drinking tea. Cannabinoids may inhibit efflux transporters and drug-metabolising enzymes, possibly inducing pharmacokinetic interactions with anticancer drugs being substrates for these proteins. This may enhance the cytostatic effect and/or drug-related adverse effects. Reversely, it may enable dose reduction. Similar interactions are likely with drugs used for symptom management treating pain, nausea, vomiting and anorexia. Cannabis products are usually well tolerated and may improve the quality of life of patients with cancer (although not unambiguously proven). The combination with immunotherapy seems undesirable because of the immunosuppressive action of cannabinoids. Further clinical research is warranted to scientifically support (refraining from) using cannabis products in patients with cancer.

Abstract
Cannabinoid CB2 receptor (CB2R) agonists are investigated as therapeutic agents in the clinic. However, their molecular mode-of-action is not fully understood. Here, we report the discovery of LEI-102, a CB2R agonist, used in conjunction with three other CBR ligands (APD371, HU308, and CP55,940) to investigate the selective CB2R activation by binding kinetics, site-directed mutagenesis, and cryo-EM studies. We identify key residues for CB2R activation. Highly lipophilic HU308 and the endocannabinoids, but not the more polar LEI-102, APD371, and CP55,940, reach the binding pocket through a membrane channel in TM1-TM7. Favorable physico-chemical properties of LEI-102 enable oral efficacy in a chemotherapy-induced nephropathy model. This study delineates the molecular mechanism of CB2R activation by selective agonists and highlights the role of lipophilicity in CB2R engagement. This may have implications for GPCR drug design and sheds light on their activation by endogenous ligands.

Abstract
BACKGROUND The legalization of cannabis in several states has led to increased documented use in the population. Bariatric surgery patients are no exception with estimates of anywhere from 6 to 8%. Cannabis is known to be associated with increased appetite, mood disorders, hyperphagia, and rarely, hyperemesis, which can potentially affect post-surgical weight loss. We aim to study the differences in bariatric surgery outcomes between cannabis users and non-users. METHODS A retrospective review identified patients undergoing bariatric surgery. Patients were divided into two groups, cannabis users (CU) and non-cannabis users (non-CU). Cannabis users (defined as using at least once weekly) and a group of non-users were called to obtain additional information. Primary outcome was weight loss. Secondary outcomes included incidence of post-operative nausea and vomiting (PONV), length of stay (LOS), readmission, and need for additional intervention. RESULTS A cohort of 364 sleeve gastrectomy patients met inclusion criteria, 31 (8.5%) CU and 333 (91.5%) non-CU. There was no difference in EWL between CU and non-CU at 1 week, 1 month, 3 months, 6 months, 9 months, 1 year, and 2 years. However, the CU group trended towards greater EWL at 3 years (52.9% vs. 38.1%, p = 0.094) and at 5 years (49.8% vs. 32.7%, p = 0.068). There were no significant differences between CU and non-CU with respect to either incidence or severity of PONV at one year after surgery or longer follow-up. CONCLUSION Cannabis users did not experience inferior weight loss after bariatric surgery despite common assumptions that appetite stimulation can lead to suboptimal weight loss outcomes. Our findings add to other work challenging this dogma. Larger, long-term, multicenter studies are warranted.

Abstract
The management of visceral pain in patients with disorders of gut-brain interaction, notably irritable bowel syndrome, presents a considerable clinical challenge, with few available treatment options. Patients are increasingly using cannabis and cannabinoids to control abdominal pain. Cannabis acts on receptors of the endocannabinoid system, an endogenous system of lipid mediators that regulates gastrointestinal function and pain processing pathways in health and disease. The endocannabinoid system represents a logical molecular therapeutic target for the treatment of pain in irritable bowel syndrome. Here, we review the physiological and pathophysiological functions of the endocannabinoid system with a focus on the peripheral and central regulation of gastrointestinal function and visceral nociception. We address the use of cannabinoids in pain management, comparing them to other treatment modalities, including opioids and neuromodulators. Finally, we discuss emerging therapeutic candidates targeting the endocannabinoid system for the treatment of pain in irritable bowel syndrome.

Abstract
Introduction Sleep disorders are the third most common indication for the prescription of medical cannabis products in Australia, after pain and anxiety. While the use of cannabis for medical purposes is growing in Australia, underlying consumer behaviours and patterns of use, particularly around sleep disorders, are poorly understood. Methods We conducted a subanalysis of the cross-sectional "Cannabis as Medicine Survey" 2020-2021 (CAMS-20) (N = 1600), to explore the characteristics of a sample of Australians who were using prescribed and/or illicit medical cannabis to treat a self-reported sleep disorder. Results When asked to specify up to seven different conditions they were treating with medical cannabis, a total of 1030 (64%) respondents [mean (SD) 44.9 (13.6) years] selected a sleep disorder, with "insomnia disorder" (85.5%), 'sleep-related movement disorders' (26%) and 'sleep-related breathing disorders' (11.1%) the most common subtypes. Only 165 (16.8%) respondents selected a self-reported sleep disorder as the main health condition being treated. Relative to other health conditions, use of medical cannabis for a self-reported sleep disorder was associated with younger age, increased likelihood of using both prescribed and illicit forms of medical cannabis, inhaled routes of administration, and THC-dominant products. Most respondents reported a reduction in the use of benzodiazepines and alcohol since starting medical cannabis. Binary logistic regression showed that respondents who predominantly used inhaled routes of administration, and concomitant use of medical cannabis for pain, mental health and/or substance use disorder, or a gastrointestinal disorder, were significantly more likely to also use medical cannabis to treat a self-reported sleep disorder. Conclusion Overall, these results suggest that self-reported sleep disorders are often being treated with medical cannabis alongside other health conditions (often pain or a mental health disorder) and that use of inhaled methods, THC-dominant products, and illicit sources of medical cannabis are common among people with self-reported sleep disorders in Australia.

Abstract
ZusammenfassungDie medizinische Verwendung von Cannabis hat in den letzten Jahren in Europa und Nordamerika an Popularität gewonnen. Cannabinoide sind sowohl als Fertigarzneimittel als auch in Blüten- und Extraktform verfügbar. Der vorliegende Artikel legt den Fokus auf die supportive Therapie onkologischer Patienten. Mögliche Indikationen sind Schmerzen, Chemotherapie-bedingte Übelkeit und Erbrechen, Appetitlosigkeit und Geschmacksveränderungen. Trotz des enormen Hypes um Cannabis als Medizin ist die Evidenz für dessen Anwendung bei onkologischen Patienten unzureichend. Palliativpatienten mit refraktären Symptomen könnten jedoch geeignete Kandidaten für einen Therapieversuch darstellen. Der entscheidende Parameter für die Auswahl eines Cannabis-Arzneimittels ist die THC/CBD-Ratio. Orale Einnahmeformen bieten sich gerade für Cannabis-naive und ältere Patienten an. Psychische und kardiovaskuläre Nebenwirkungen sind nicht zu unterschätzen.

Abstract
The endocannabinoid system (ECS) dynamically regulates many aspects of mammalian physiology. ECS has gained substantial interest since growing evidence suggests that it also plays a major role in several pathophysiological conditions due to its ability to modulate various underlying mechanisms. Furthermore, cannabinoids, as components of the cannabinoid system (CS), have proven beneficial effects such as anti-inflammatory, immunomodulatory, neuromodulatory, antioxidative, and cardioprotective effects. In this comprehensive review, we aimed to describe the complex interaction between CS and most common age-related diseases such as neuro-degenerative, oncological, skeletal, and cardiovascular disorders, together with the potential of various cannabinoids to ameliorate the progression of these disorders. Since chronic inflammation is postulated as the pillar of all the above-mentioned medical conditions, we also discuss in this paper the potential of CS to ameliorate aging-associated immune system dysregulation.

Abstract
Introduction: Opioid use disorder (OUD) is a major public health crisis worldwide. Patients with OUD inevitably experience withdrawal symptoms when they attempt to taper down on their current opioid use, abstain completely from opioids, or attempt to transition to certain medications for opioid use disorder. Acute opioid withdrawal can be debilitating and include a range of symptoms such as anxiety, pain, insomnia, and gastrointestinal symptoms. Whereas acute opioid withdrawal only lasts for 1-2 weeks, protracted withdrawal symptoms can persist for months after the cessation of opioids. Insufficient management of opioid withdrawal often leads to devastating results including treatment failure, relapse, and overdose. Thus, there is a critical need for cost-effective, nonopioid medications, with minimal side effects to help in the medical management of opioid withdrawal syndrome. We discuss the potential consideration of cannabidiol (CBD), a nonintoxicating component of the cannabis plant, as an adjunctive treatment in managing the opioid withdrawal syndrome. Materials and Methods: A review of the literature was performed using keywords related to CBD and opioid withdrawal syndrome in PubMed and Google Scholar. A total of 144 abstracts were identified, and 41 articles were selected where CBD had been evaluated in clinical studies relevant to opioid withdrawal. Results: CBD has been reported to have several therapeutic properties including anxiolytic, antidepressant, anti-inflammatory, anti-emetic, analgesic, as well as reduction of cue-induced craving for opioids, all of which are highly relevant to opioid withdrawal syndrome. In addition, CBD has been shown in several clinical trials to be a well-tolerated with no significant adverse effects, even when co-administered with a potent opioid agonist. Conclusions: Growing evidence suggests that CBD could potentially be added to the standard opioid detoxification regimen to mitigate acute or protracted opioid withdrawal-related symptoms. However, most existing findings are either based on preclinical studies and/or small clinical trials. Well-designed, prospective, randomized-controlled studies evaluating the effect of CBD on managing opioid withdrawal symptoms are warranted.

Abstract
The endocannabinoid system is located throughout the central and peripheral nervous systems, endocrine system, gastrointestinal system, and within inflammatory cells. The use of medical cannabinoids has been gaining traction as a viable treatment option for varying illnesses in recent years. Research is ongoing looking at the effect of cannabinoids for treatment of common otolaryngologic pathologies. This article identifies common otolaryngologic pathologies where cannabinoids may have benefit, discusses potential drawbacks to cannabinoid use, and suggests future directions for research in the application of medical cannabinoids.

Abstract
BACKGROUND Cannabis products, including the cannabinoids CBD and THC, are rising in popularity and increasingly used for medical purposes. While there is some evidence that cannabinoids improve cancer-associated symptoms, understanding regarding appropriate use remains incomplete. PURPOSE To describe patient experiences with medical cannabis with focus on use contexts and patients' reported benefits and harms. METHODS A standardized intake form was implemented in a dedicated medical cannabis clinic at an NCI-designated cancer center; data from this form was abstracted for all initial visits from October 2019 to October 2020. We report descriptive statistics, chi-square analysis, and multivariate logistic regression. RESULTS Among 163 unique new patients, cannabis therapy was commonly sought for sleep, pain, anxiety, and appetite. Twenty-nine percent expressed interest for cancer treatment; 40% and 46% reported past use of CBD and THC, respectively, for medical purposes. Among past CBD users, the most commonly reported benefits were less pain (21%) or anxiety (17%) and improvement in sleep (15%); 92% reported no side effects. Among those with past THC use, reported benefits included improvement in appetite (40%), sleep (32%), nausea (28%), and pain (17%); side effects included feeling "high." Seeking cannabis for anti-neoplastic effects was associated with receipt of active cancer treatment in both univariate and multivariate analysis. CONCLUSION Cancer patients seek medical cannabis to address a wide variety of concerns despite insufficient evidence of benefits and harms. As more states move to legalize medical and recreational cannabis, cancer care providers must remain aware of emerging data and develop knowledge and skills to counsel their patients about its use.

Abstract
Cannabis is one of the most commonly used and abused illicit drugs in the world today. The United States (US) currently has the highest annual prevalence rate of cannabis consumption in the world, 17.9% in individuals aged 12 or older, and it is on the rise. With increasing cannabis use comes the potential for an increase in abuse, and according to the Substance Abuse and Mental Health Services Administration (SAMHSA), approximately 5.1% of Americans had Cannabis Use Disorder (CUD) in 2020. Research has shown that genetics and epigenetics play a significant role in cannabis use and CUD. In fact, approximately 50–70% of liability to CUD and 40–48% of cannabis use initiation have been found to be the result of genetic factors. Cannabis usage and CUD have also been linked to an increased risk of psychiatric disorders and Reward Deficiency Syndrome (RDS) subsets like schizophrenia, depression, anxiety, and substance use disorder. Comprehension of the genetic and epigenetic aspects of cannabinoids is necessary for future research, treatment plans, and the production of pure cannabinoid compounds, which will be essential for FDA approval. In conclusion, having a better understanding of the epigenetic and genetic underpinnings of cannabis use, CUD, and the endocannabinoid system as a whole will aid in the development of effective FDA-approved treatment therapies and the advancement of personalized medicine.

Abstract
To explore the efficacy of low-frequency electric pulse therapy (LFEPT) combined with 2 antiemetics in the prevention and treatment of cisplatin-based chemotherapy-induced nausea and vomiting (CINV) in patients with lung adenocarcinoma. A total of 82 patients with lung adenocarcinoma who received cisplatin-based chemotherapy were randomly divided into the experimental group (n=41) and control group (n=41) by random numerical table method. The experimental group was treated with LFEPT combined with 2 antiemetic drugs (tropisetron hydrochloride and dexamethasone hydrochloride), while the control group was treated with the same 2 antiemetic drugs. Revised index of nausea and vomiting and retching (R-INVR) and Functional Living Index-Emesis (FLIE) scale were used to quantitatively evaluate the symptoms of nausea and vomiting after chemotherapy, and the effect of LFEPT in the prevention and treatment of CINV was observed. The baseline characteristics had no statistical difference between the 2 groups. The degree of nausea reaction, vomiting, and dry retching were similar in 2 groups on the first day after chemotherapy. However, the degree of nausea reaction, vomiting, and dry retching were significantly improved in the experimental group than that of the control group on 2 to 5 days with all P<.05. The score of FLIE had no difference between the 2 groups on the first day after chemotherapy (84.05 vs 82.69, P=.30), and the score was significantly higher in experiment group on day 6 compared with the control group (103.71 vs 89.38, P=.02). The side effects had no difference between the 2 groups. The LFEPT can significantly ameliorate CINV in patients with lung adenocarcinoma, which is worthy of clinical application.

Abstract
BACKGROUND Medical cannabinoids differ in their pharmacology and may have different treatment effects. We aimed to conduct a pharmacology-based systematic review (SR) and meta-analyses of medical cannabinoids for efficacy, retention and adverse events. METHODS We systematically reviewed (registered at PROSPERO: CRD42021229932) eight databases for randomized controlled trials (RCTs) of dronabinol, nabilone, cannabidiol and nabiximols for chronic pain, spasticity, nausea /vomiting, appetite, ALS, irritable bowel syndrome, MS, Chorea Huntington, epilepsy, dystonia, Parkinsonism, glaucoma, ADHD, anorexia nervosa, anxiety, dementia, depression, schizophrenia, PTSD, sleeping disorders, SUD and Tourette. Main outcomes and measures included patient-relevant/disease-specific outcomes, retention and adverse events. Data were calculated as standardized mean difference (SMD) and ORs with confidence intervals (CI) via random effects. Evidence quality was assessed by the Cochrane Risk of Bias and GRADE tools. RESULTS In total, 152 RCTs (12,123 participants) were analysed according to the type of the cannabinoid, outcome and comparator used, resulting in 84 comparisons. Significant therapeutic effects of medical cannabinoids show a large variability in the grade of evidence that depends on the type of cannabinoid. CBD has a significant therapeutic effect for epilepsy (SMD - 0.5[CI - 0.62, - 0.38] high grade) and Parkinsonism (- 0.41[CI - 0.75, - 0.08] moderate grade). There is moderate evidence for dronabinol for chronic pain (- 0.31[CI - 0.46, - 0.15]), appetite (- 0.51[CI - 0.87, - 0.15]) and Tourette (- 1.01[CI - 1.58, - 0.44]) and moderate evidence for nabiximols on chronic pain (- 0.25[- 0.37, - 0.14]), spasticity (- 0.36[CI - 0.54, - 0.19]), sleep (- 0.24[CI - 0.35, - 0.14]) and SUDs (- 0.48[CI - 0.92, - 0.04]). All other significant therapeutic effects have either low, very low, or even no grade of evidence. Cannabinoids produce different adverse events, and there is low to moderate grade of evidence for this conclusion depending on the type of cannabinoid. CONCLUSIONS Cannabinoids are effective therapeutics for several medical indications if their specific pharmacological properties are considered. We suggest that future systematic studies in the cannabinoid field should be based upon their specific pharmacology.

Abstract
Simple Summary Mesothelioma is a deadly disease with few treatment options. Phytocannabinoids derived from the cannabis plant are garnering interest for their anti-cancer properties, however very little is known about their effects in mesothelioma. We aimed to assess whether phytocannabinoids have anti-cancer effects in mesothelioma and potential modes of action. We showed that several phytocannabinoids inhibited growth of mesothelioma cells, with two phytocannabinoids, cannabidiol (CBD) and cannabigerol (CBG), being the most potent. CBD and CBG also inhibited mesothelioma cell migration and invasion. Gene expression analysis highlighted signalling pathways that play a role in how CBD and CBG may exert their anti-cancer effects. CBD and CBG were unable to increase survival in a rat model of mesothelioma but this may be due to limitations in the drug delivery method. Abstract Mesothelioma is an aggressive cancer with limited treatment options and a poor prognosis. Phytocannabinoids possess anti-tumour and palliative properties in multiple cancers, however their effects in mesothelioma are unknown. We investigated the anti-cancer effects and potential mechanisms of action for several phytocannabinoids in mesothelioma cell lines. A panel of 13 phytocannabinoids inhibited growth of human (MSTO and H2452) and rat (II-45) mesothelioma cells in vitro, and cannabidiol (CBD) and cannabigerol (CBG) were the most potent compounds. Treatment with CBD or CBG resulted in G0/G1 arrest, delayed entry into S phase and induced apoptosis. CBD and CBG also significantly reduced mesothelioma cell migration and invasion. These effects were supported by changes in the expression of genes associated with the cell cycle, proliferation, and cell movement following CBD or CBG treatment. Gene expression levels of CNR1, GPR55, and 5HT1A also increased with CBD or CBG treatment. However, treatment with CBD or CBG in a syngeneic orthotopic rat mesothelioma model was unable to increase survival. Our data show that cannabinoids have anti-cancer effects on mesothelioma cells in vitro and alternatives of drug delivery may be needed to enhance their effects in vivo.

Abstract
Autism spectrum disorder (ASD) is often associated with debilitating sleep disturbances. While anecdotal evidence suggests the positive effect of cannabinoids, randomized studies are lacking. Here, we report the effects of cannabinoid treatment on the sleep of 150 children and adolescents with ASD, as part of a double-blind, placebo-controlled study that assessed the impact of cannabinoid treatment on behavior (NCT02956226). Participants were randomly assigned to one of the following three treatments: (1) whole-plant cannabis extract, containing cannabidiol (CBD) and Δ9-Tetrahydrocannabinol (THC) in a 20:1 ratio, (2) purified CBD and THC extract in the same ratio, and (3) an oral placebo. After 12 weeks of treatment (Period 1) and a 4-week washout period, participants crossed over to a predetermined, second 12-week treatment (Period 2). Sleep disturbances were assessed using the Children’s Sleep-Habit Questionnaire (CSHQ). We found that the CBD-rich cannabinoid treatment was not superior to the placebo treatment in all aspects of sleep measured by the CSHQ, including bedtime resistance, sleep-onset delay, and sleep duration. Notably, regardless of the treatment (cannabinoids or placebo), improvements in the CSHQ total score were associated with improvements in the autistic core symptoms, as indicated by the Social Responsiveness Scale total scores (Period 1: r = 0.266, p = 0.008; Period 2: r = 0.309, p = 0.004). While this study failed to demonstrate that sleep improvements were higher with cannabinoids than they were with the placebo treatment, further studies are required.

Abstract
PURPOSE Despite the inconclusiveness regarding health effects of cannabinoids among cancer patients, studies from non-European countries suggest that the medical-intended consumption of such products by this patient group is significant. The current study analyses cannabinoid usage among oncology patients receiving systemic treatment in the Netherlands. METHODS The current study included adult patients receiving intravenous systemic therapy at Maastricht Comprehensive Cancer Centre, for a solid malignancy. Participants were asked to complete an anonymous questionnaire including questions on demographic variables, clinical variables and cannabinoid consumption. RESULTS A total of 153 patients with solid cancer were included in this study. Almost 25% reported usage of cannabinoids for medical purposes, with 15% of the patients currently using the substance. Additionally, 18% of non-users considered future medical usage. In 48% of the cases, consumption was reported by the oncologist. The proposed anti-cancer effect was reported by 46% of the users as motivation for consumption. Current users were mainly palliative patients and 54% of the users were undergoing immunotherapy. Intention of treatment and type of therapy were predictive factors for consumption. Cannabinoid-oil was the most frequently used way of consumption. CONCLUSION This study underlines the high number of cannabinoid users among oncology patients in the Netherlands in presumed absence of clinical guidance. It highlights the essence of a pro-active role of the clinician, assessing cannabinoid usage and educating the patients on the most recent evidence regarding its potential benefits and risks. Further studies on clinical decision making and efficacy of cannabinoids are recommended, to improve clinical guidance.

Abstract
The medical use of Cannabis has gained popularity in Europe and Northern America in recent years. Cannabinoids are available as finished pharmaceuticals, flowers and extracts. This article focuses on supportive medicine for oncological patients. Possible indications are pain, chemotherapy-induced nausea and vomiting, loss of appetite and altered taste perception. Despite the enormous cannabis hype in medicine, the evidence for its use in oncology patients is insufficient. However, palliative patients with refractory symptoms could be candidates for a therapeutic trial. The key parameter for choosing a cannabis medicinal product is the THC/CBD ratio. Oral forms of administration are particularly suitable for cannabis-naive and older patients. Mental and cardiovascular side effects should not be underestimated.

Abstract
PURPOSE This study explored whether symptom relief differs by sex in patients with cancer receiving medical cannabis (MC) therapy. METHODS This is an analysis of data collected from patients with cancer enrolled in the Quebec Cannabis Registry. MC was initiated for the therapeutic management of cancer symptoms. Patients completed the revised Edmonton Symptom Assessment System (ESAS-r) questionnaire at baseline and 3-month follow-up. We examined the interaction between sex and time on each ESAS-r symptom and the interaction between time and tetrahydrocannabinol:cannabidiol (THC:CBD) ratios for each sex on total symptom burden. RESULTS The analysis included 358 patients (M: 171). There were no sex differences in baseline ESAS-r scores. Three months of MC therapy led to significant improvements in pain (M: - 1.4 ± 0.3, p < 0.001; F: - 1.1 ± 0.3, p < 0.01), tiredness (M: - 1.7 ± 0.4, p < 0.001; F: - 1.2 ± 0.4, p < 0.05), anxiety (M: - 1.1 ± 0.4, p < 0.05; F: - 1.2 ± 0.4, p < 0.001), and well-being (M: - 1.2 ± 0.4, p < 0.05; F: - 1.4 ± 0.4, p < 0.01) in both sexes. Only F perceived improved drowsiness (- 1.1 ± 0.4, p < 0.05), nausea (- 0.9 ± 0.3, p < 0.05), lack of appetite (- 1.7 ± 0.4, p < 0.001), and shortness of breath (- 0.9 ± 0.3, p < 0.05). From baseline to 3-month follow-up, THC-dominant MC significantly reduced pain (- 1.52 ± 0.52, p < 0.05) in M, whereas in F it diminished nausea (- 2.52 ± 0.70, p < 0.01) and improved well-being (- 2.41 ± 0.79, p < 0.05). THC:CBD-balanced products significantly reduced pain (- 1.48 ± 0.49, p < 0.05), tiredness (- 1.82 ± 0.62, p < 0.05), anxiety (- 1.83 ± 0.54, p < 0.05), and improved well-being (- 2.01 ± 0.56, p < 0.01) in M. CBD-dominant products did not offer significant symptom relief in either sex. CONCLUSION The perceived relief of cancer symptoms from MC differs between sexes. More randomized controlled trials are needed to confirm our findings.

Abstract
A regulatory framework allowing legal access to medicinal cannabis (MC) products has operated in Australia since November 2016. MC prescribing by healthcare practitioners (HCPs) is primarily conducted through the Special Access Scheme - Category B (SAS-B) pathway, through which prescribers apply to the Therapeutic Goods Administration (TGA–the federal regulator) for approval to prescribe a category of product to an individual patient suffering from a specific indication. The dataset collected by the TGA provides a unique opportunity to examine MC prescribing trends over time in the Australian population. Here we analysed this TGA SAS-B dataset since inception with respect to age, gender, product type (e.g., oil, flower, etc.), CBD content, indication treated, and prescriber location. Results are presented descriptively as well as being analysed using non-linear regression models. Relationship between variables were explored via correspondence analyses. Indications were classified with reference to the International Statistical Classification of Diseases and Related Health Problems (10th Revision). As of 31 August 2021, a total of 159,665 SAS-B approvals had been issued for MC products, 82.4% of were since January 2020. Leading indications for approvals were for pain, anxiety, and sleep disorders. Oil products were the most popular product type, while CBD-dominant products (≥98% CBD) accounted for 25.1% of total approvals. Approvals for flower products increased markedly during 2020–2021, as did approvals involving younger age groups (18–31 years old), male patients, and non-CBD dominant products. A disproportionate number of SAS-B MC applications (around 50%) came from HCPs in the state of Queensland. Associations between patient gender and age and/or indication with product type were found. For example, approvals for oil products were commonly associated with approvals for pain. While, overall prescribing increased dramatically over the last 2 years of analysis, stabilization of approval numbers is evident for some indications, such as pain. Current prescribing practices do not always reflect provided TGA guidance documents for MC prescribing. While acknowledging some limitations around the SAS-B dataset, it provides a unique and valuable resource with which to better understand current prescribing practices and utilisation of MC products within Australia.

Abstract
Simple Summary Emerging evidence suggests positive outcomes from the use of CBD as a cancer treatment. CBD can relieve cancer pain and ease the side effects of chemotherapy; however, there is less research about the mechanism of CBD’s anticancer effects. In this article, recent studies on the efficacy and mechanisms of CBD’s anticancer effects in cell- and animal-based models and human clinical studies are reviewed. Abstract Cannabis sativa L. (Cannabis) and its bioactive compounds, including cannabinoids and non-cannabinoids, have been extensively studied for their biological effects in recent decades. Cannabidiol (CBD), a major non-intoxicating cannabinoid in Cannabis, has emerged as a promising intervention for cancer research. The purpose of this review is to provide insights into the relationship between CBD and cancer based on recent research findings. The anticancer effects of CBD are mainly mediated via its interaction with the endocannabinoid system, resulting in the alleviation of pain and the promotion of immune regulation. Published reviews have focused on the applications of CBD in cancer pain management and the possible toxicological effects of its excessive consumption. In this review, we aim to summarize the mechanisms of action underlying the anticancer activities of CBD against several common cancers. Studies on the efficacy and mechanisms of CBD on cancer prevention and intervention in experimental models (i.e., cell culture- and animal-based assays) and human clinical studies are included in this review.

Abstract
Cannabis has long been regarded as a recreational substance in the Western world. The recent marketing authorization of some medicinal products of industrial origin and the introduction onto the market of inflorescences for medical use mean that medical doctors can now prescribe Cannabis-based medicines in those countries which allow it. Nevertheless, there is still considerable controversy on this topic in the scientific community. In particular, this controversy concerns: the plant species to be used; the pathologies that can be treated and consequently the efficacy and safety of use; the routes of administration; the methods of preparation; the type and dosage of cannabinoids to be used; and, the active molecules of interest. As such, although medical Cannabis has been historically used, the results of currently completed and internationally published studies are inconclusive and often discordant. In light of these considerations, the aim of this work is to analyse the current legislation in countries that allow the use of medical Cannabis, in relation to the impact that this legislation has had on clinical trials. First of all, a literature search has been performed (PubMed and SciFinder) on clinical trials which involved the administration of Cannabis for medical use over the last 3 years. Of the numerous studies extrapolated from the literature, only about 43 reported data on clinical trials on medical Cannabis, with these mainly being performed in Australia, Brazil, Canada, Denmark, Germany, Israel, Netherlands, Switzerland, the United Kingdom and the United States of America. Once the reference countries were identified, an evaluation of the legislation in relation to Cannabis for medical use in each was carried out via the consultation of the pertinent scientific literature, but also of official government documentation and that of local regulatory authorities. This analysis provided us with an overview of the different legislation in these countries and, consequently, allowed us to analyse, with greater awareness, the results of the clinical trials published in the last 3 years in order to obtain general interest indications in the prosecution of scientific research in this area.

Abstract
BACKGROUND Nausea and vomiting are common and distressing side effects of tumor therapy. Despite prophylaxis, 40-50% of patients suffer from nausea, and 20-30% from vomiting. Antiemetic prophylaxis and treatment are therefore of great importance for improving patients' quality of life and preventing sequelae such as tumor cachexia. METHODS The recommendations presented here are based on international and national guidelines, updated with publications retrieved by a selective search in the PubMed and Cochrane Library databases, with special attention to randomized controlled trials and meta-analyses that have appeared in the past 5 years since the German clinical practice guideline on supportive therapy was published. RESULTS Risk-adjusted prevention and treatment is based on the identification of treatment-related and patient-specific risk factors, including female sex and younger age. Parenteral tumor therapy is divided into four risk classes (minimal, low, moderate, high), and oral tumor therapy into two (minimal/low, moderate/high). In radiotherapy, the radiation field is of decisive importance. The antiemetic drugs most commonly used are 5-HT3-RA, NK1-RA, and dexamethasone; olanzapine has proven beneficial as an add-on or rescue drug. The use of steroids in patients being treated with drug combinations including checkpoint inhibitors is discussed controversially because of the potentially reduced therapeutic response. Benzodiazepines, dimenhydrinate, and cannabinoids can be used as backup antiemetics. Acupuncture/acupressure, ginger, and progressive muscle relaxation are pos - sible alternative methods. CONCLUSION Detailed, effective, risk profile-adapted algorithms for the prevention and treatment of nausea and vomiting are now available for patients undergoing classic chemotherapy regimens or combined radiotherapy and chemotherapy. Optimal symptom control for patients undergoing oral tumor therapy over multiple days in the outpatient setting remains a challenge.

Abstract
Although new drugs are being developed for cancer treatment, classical chemotherapeutic agents are still front-line therapies, despite their frequent association with severe side effects that can hamper their use. Cannabinoids may prevent or palliate some of these side effects. The aim of the present study is to review the basic research which has been conducted evaluating the effects of cannabinoid drugs in the treatment of three important side effects induced by classical chemotherapeutic agents: nausea and vomiting, neuropathic pain and cognitive impairment. Several published studies have demonstrated that cannabinoids are useful in preventing and reducing the nausea, vomits and neuropathy induced by different chemotherapy regimens, though other side effects can occur, such as a reduction of gastrointestinal motility, along with psychotropic effects when using centrally-acting cannabinoids. Thus, peripherally-acting cannabinoids and new pharmacological options are being investigated, such as allosteric or biased agonists. Additionally, due to the increase in the survival of cancer patients, there are emerging data that demonstrate an important cognitive deterioration due to chemotherapy, and because the cannabinoid drugs have a neuroprotective effect, they could be useful in preventing chemotherapy-induced cognitive impairment (as demonstrated through studies in other neurological disorders), but this has not yet been tested. Thus, although cannabinoids seem a promising therapeutic approach in the treatment of different side effects induced by chemotherapeutic agents, future research will be necessary to find pharmacological options with a safer profile. Moreover, a new line of research awaits to be opened to elucidate their possible usefulness in preventing cognitive impairment.

Abstract
OPINION STATEMENT Cannabinoids have been purported as having a wide range of therapeutic uses although currently, there is minimal evidence to support these claims. Patients with advanced cancer experience many distressing symptoms, with some turning to medicinal cannabis to help alleviate these. Focus has fallen on cannabidiol (CBD) as a potential treatment for a variety of symptoms in advanced cancer due to the lack of psychoactive side effects and the potential molecular mechanisms of action associated with this cannabinoid. Many cannabinoid products are easily available in the community, and more countries are legalizing or allowing over the counter products. Studies show that CBD is generally well tolerated, but there are many potential drug interactions that have not been well studied. Few studies have specifically looked at the role of CBD in treating cancer symptoms, with most focusing on combination cannabinoid products. There are currently many unknowns associated with CBD, including which symptoms it might be best for, appropriate dosing, and route of administration. This is especially important in advanced cancer where patients often have significant organ dysfunction and frailty that could impact on the pharmacology of CBD. A small pilot study has shown promise for a role of CBD in the psychological symptoms associated with advanced cancer. Further research is currently underway to further clarify the role of CBD in this setting and to understand how best it might help our patients. Currently we advocate that CBD be used in supervised clinical trials, so that efficacy and adverse effects can be closely monitored.
