Abstract
BACKGROUND Cannabis use is common in inflammatory bowel disease (IBD). Recent studies demonstrated that use of cannabis may relieve symptoms; however, it is still unclear how safe cannabis and its derivatives are for IBD patients. We performed this study to evaluate the impact of cannabis use on several key clinical outcomes in IBD. METHODS We performed a retrospective study using the TriNetX Diamond Network. Cannabis use and noncannabis use subcohorts were identified for 3 patient groups: (1) IBD, (2) Crohn's disease (CD), and (3) ulcerative colitis (UC). Baseline differences between subcohorts for each group were controlled by propensity score matching. In each group, we compared relative incidence of emergency department (ED) visits, hospitalization, corticosteroid use, opioid use, IBD-related surgery, and death between cannabis users and noncannabis users. RESULTS Inflammatory bowel disease cannabis users demonstrated an increased risk for corticosteroid use (risk ratios [R],1.095; 95% CI, 1.021-1.174; P = .011), ED visits (RR, 2.143; 95% CI, 2.034-2.257; P < .001), hospitalizations (RR, 1.925; 95% CI, 1.783-2.079; P < .001) and opioid use (RR, 1.35; 95% CI, 1.14-1.6); P < .001), but not an increased risk of IBD-related surgery or death. The CD and UC groups exhibited similar outcomes, except only CD demonstrated an increased risk for corticosteroid and opioid use. CONCLUSIONS Cannabis use in IBD patients is associated with several poor clinical outcomes, including increased risk of corticosteroid and opioid use, ED visits and hospitalization, though not IBD-related surgery or death. It is not clear what drives these risks or whether they are directly related to IBD-associated disease activity or other factors. Further prospective studies are warranted to more carefully investigate these relationships.

Abstract
BACKGROUND As far as 80% of people diagnosed with multiple sclerosis (MS) experience disabling symptoms in the course of the disease, such as spasticity and neuropathic pain. As first-line symptomatic therapy is associated with important adverse reactions, cannabinoids have become increasingly popular among patients with MS. This review intends to provide an overview of the evidence of the role of cannabinoids in treating symptoms related to MS and to encourage further research on this matter. AREAS OF UNCERTAINTY To date, the evidence supporting the role of cannabis and its derivatives in alleviating the MS-related symptoms comes only from studies on experimental models of demyelination. To the best of our knowledge, relatively few clinical trials inquired about the therapeutic effects of cannabinoids on patients with MS, with variable results. DATA SOURCES We conducted a literature search through PubMed and Google Scholar from the beginning until 2022. We included articles in English describing the latest findings regarding the endocannabinoid system, the pharmacology of cannabinoids, and their therapeutic purpose in MS. RESULTS Evidence from preclinical studies showed that cannabinoids can limit the demyelination process, promote remyelination, and have anti-inflammatory properties by reducing immune cell infiltration of the central nervous system in mice with experimental autoimmune encephalomyelitis. Moreover, it has been established that experimental autoimmune encephalomyelitis mice treated with cannabinoids experienced a significant reduction of symptoms and slowing of the disease progression. Given the complexity of human immune and nervous systems, cannabinoids did not have the anticipated effects on human subjects. However, data obtained from clinical trials showed some beneficial results of cannabinoids as a single or as add-on therapy in reducing the spasticity and pain related to MS. CONCLUSION Considering their various mechanisms of action and good tolerability, cannabinoids remain an interesting therapy for spasticity and chronic pain related to MS.

Abstract
Purpose of Review Policy implications from changes in recreational cannabis laws (RCLs) have raised public health concerns. While numerous studies have examined the impact of RCLs on cannabis use, there is less research on the risk of developing cannabis use disorder (CUD). This review summarizes the latest research on the effects of RCLs on CUD prevalence and cannabis treatment admissions. Recent Findings Nine studies were published between 2016 - 2022 that examined RCLs and CUD or treatment. Findings generally indicate an increase in CUD prevalence associated with legalization, but effects differ by age group. There was no significant association between legalization and CUD treatment admissions, and CUD admissions decreased overall during the study periods. Summary To improve policy, prevention, and treatment services, policymakers should monitor RCLs' effects on adverse public health outcomes and researchers should consider the effects on individual and community-level characteristics. We discuss methodological challenges in conducting state-level research and provide suggestions for future studies.

Abstract
INTRODUCTION Reddit hosts a large active community of members dedicated to the discussion of cannabinoid hyperemesis syndrome. We sought to describe common themes discussed and the most frequently mentioned triggers and therapies for cannabinoid hyperemesis syndrome exacerbations in the Reddit online community. METHODS Data collected from six subreddits were filtered using natural language processing to curate posts referencing cannabinoid hyperemesis syndrome. Based on a manual review of posts, common themes were identified. A machine learning model was trained using the manually categorized data to automatically classify the themes for the rest of the posts so that their distributions could be quantified. RESULTS From August 2018 to November 2022, 2683 unique posts were collected. Thematic analysis resulted in five overall themes: cannabinoid hyperemesis syndrome-related science; symptom timing; cannabinoid hyperemesis syndrome treatment and prevention; cannabinoid hyperemesis syndrome diagnosis and education; and health impacts. Additionally, 447 trigger and 664 therapy-related posts were identified. The most commonly mentioned triggers for cannabinoid hyperemesis syndrome episodes included: food and drink (n = 62), cannabinoids (n = 45), mental health (e.g., stress, anxiety) (n = 27), and alcohol (n = 22). Most commonly mentioned cannabinoid hyperemesis syndrome therapies included: hot water/bathing (n = 62), hydration (n = 60), antiemetics (n = 42), food and drink (n = 38), gastrointestinal medications (n = 38), behavioral therapies (e.g., meditation, yoga) (n = 35), and capsaicin (n = 29). DISCUSSION Reddit posts for cannabinoid hyperemesis syndrome provide a valuable source of community discussion and individual reports of people experiencing cannabinoid hyperemesis syndrome. Mental health and alcohol were frequently reported triggers within the posts but are not often identified in the literature. While many of the therapies mentioned are well documented, behavioral responses such as meditation and yoga have not been explored by the scientific literature. CONCLUSIONS Knowledge shared via online social media platforms contains detailed information on self-reported cannabinoid hyperemesis syndrome disease and management experiences, which could serve as valuable data for the development of treatment strategies. Further longitudinal studies in patients with cannabinoid hyperemesis syndrome are needed to corroborate these findings.

Abstract
INTRODUCTION Cannabinoid hyperemesis syndrome (CHS) is a clinical diagnosis characterized by symptoms of recurrent nausea, vomiting, and severe abdominal pain in the setting of chronic cannabis use. Symptoms of CHS are frequently unresponsive to standard antiemetic therapy. Topical capsaicin applied to the abdomen has been cited as a potential effective agent for CHS however robust evidence is lacking. METHODS This was a single-center retrospective cohort study to evaluate the efficacy of topical capsaicin in pediatric and adult patients presenting to the emergency department (ED) with suspected or confirmed CHS. The primary outcome assessed was if utilization of capsaicin for CHS resulted in more patients achieving an "efficacious" result, defined as only requiring ≤1 rescue medication for symptom relief after receiving capsaicin or after administration of the first agent in patients who did not receive capsaicin during their ED course. Secondary outcomes included total ED length of stay, time to discharge after administration of the reference agent (RA), proportion of patients requiring admission, total number of medication doses given for symptom relief, change in pain score and episodes of emesis, and proportion of patients returning to the ED within 24 h for the same complaint. Additional analyses were also performed to explore patient characteristics that may be predictive of capsaicin efficacy. RESULTS 201 patients were included in the final analysis of which 25 were <21 years old and seen in the pediatric ED. A greater proportion of patients in the capsaicin group achieved the primary outcome of efficacy as compared to patients who did not receive capsaicin (55% vs 21%, p < 0.001, unadjusted OR 1.44 [95% CI 0.586-0.820]). There were no differences in secondary outcomes except for time to discharge after administration of the RA which was shorter in the capsaicin group (3.72 vs 6.11 h, p = 0.001). CONCLUSION Significantly more patients in the capsaicin group experienced efficacy compared to patients who did not. Time to discharge after administration of the reference agent was shorter for those who received capsaicin compared to patients who did not. Administration of capsaicin did not influence patients' total number of medications received or total ED length of stay. Future research is needed to determine capsaicin's efficacy when utilized earlier in therapy, ideally upon initial diagnosis of CHS, and before additional adjunct medications are administered.

Abstract
BACKGROUND Cannabis Hyperemesis Syndrome (CHS) is a clinical disorder characterized by abdominal pain and intractable vomiting among patients with chronic marijuana use. We sought to assess the efficacy of capsaicin to determine whether it could reduce ED length of stay in patients with CHS. METHODS his retrospective observational study was conducted among patients with CHS. Patients were classified based on whether they received capsaicin, which was pseudorandomized and dependent on the pharmacist available. Outcomes included time to discharge, number of medications given, bounceback rate, and admission rate. Statistical analyses included t-tests, survival analyses, and cox regressions. RESULTS 55 patients (35 capsaicin, 20 no capsaicin) met inclusion criteria. There was no difference in time to discharge between the experimental and control groups (4.46 h vs 3.52 h, p = 0.10), rounds of medications given (2.60 vs 3.54, p = 0.09), bounceback rate within 24 h (0.11 vs 0.10, p = 0.43), or admission rate to the hospital (0.19 vs 0.05, p = 0.07). A survival analysis and cox regression showed no difference in time to discharge. A subgroup analysis between patients who received capsaicin within their first two rounds of treatment had statistically significantly shorter length of stays than patients who received capsaicin afterwards, (4.83 h vs 7.09 h, p = 0.01). CONCLUSION Topical capsaicin was not associated with shorter length of stays than no capsaicin. When given earlier during an ED visit, it is associated with a shorter length of stay than when given later.

Abstract
BACKGROUND Cannabis is the most prevalent illegal drug used and the second most common cause of ED drug-related complaints in the USA. Recently, newer more potent strains, concentrated THC products, and consumption methods have become available. OBJECTIVE Our first objective was to define cannabis use in the USA and provide a summary background on its current preparations, pharmacokinetics, vital sign and physical exam findings, adverse effects, and laboratory testing. Our second objective, using the aforementioned summary as relevant background information, was to present and summarize the care and treatment of the most commonly reported cannabis-related topics relevant to ED physicians. METHODS We first performed an extensive literature search of peer-reviewed publications using New PubMed and Cochrane Central Register of Controlled Trials to identify the most commonly reported cannabis-related topics in emergency care. Once the six topic areas were identified, we undertook an extensive narrative literature review for each section of this paper using New PubMed and Cochrane Central Register of Controlled Trials from the inception of the databases to September 30, 2020. RESULTS The six subject areas that were most frequently reported in the medical literature relevant to cannabis-related ED care were acute intoxication/overdose, pediatric exposure, cannabinoid hyperemesis syndrome, cannabis withdrawal, e-cigarette or vaping product use-associated lung injury (EVALI), and synthetic cannabinoids. CONCLUSION As cannabis becomes more widely available with the adoption of state medical cannabis laws, ED-related cannabis visits will likely rise. While cannabis has historically been considered a relatively safe drug, increased legal and illegal access to newer formulations of higher potency products and consumption methods have altered the management and approach to ED patient care and forced physicians to become more vigilant about recognizing and treating some new cannabis-related life-threatening conditions.

Abstract
Cannabinoid hyperemesis syndrome is a condition characterized by cyclic severe nausea, vomiting, and abdominal pain associated with frequent, long-term marijuana use. The condition resolves with cessation of cannabis but may be temporarily relieved by bathing in hot water. Topical capsaicin cream may also alleviate symptoms, perhaps through antiemetic effects produced by activation of TRPV1 receptors, similar to that of hot water bathing. This review summarizes the epidemiology, clinical presentation, diagnosis, pathophysiology, and management of cannabinoid hyperemesis syndrome, focusing on treatment with topical capsaicin.

Role of the stress response and the endocannabinoid system in Δ 9-tetrahydrocannabinol (THC)-induced nausea. Psychopharmacology (Berl) 2020; 237:2187-2199.

Abstract
RATIONALE Dysregulation of the endocannabinoid (eCB) system by high doses of Δ9-tetrahydrocannabinol (THC) is hypothesized to generate a dysfunctional hypothalamic-pituitary-adrenal (HPA) axis contributing to cannabinoid hyperemesis syndrome (CHS). OBJECTIVES AND METHODS Using the conditioned gaping model of nausea, we aimed to determine if pre-treatments that interfere with stress, or an anti-emetic drug, interfere with THC-induced nausea in male rats. The corticotropin-releasing hormone (CRH) antagonist, antalarmin, was given to inhibit the HPA axis during conditioning. Since eCBs inhibit stress, MJN110 (which elevates 2-arachidonylglycerol (2-AG)) and URB597 (which elevates anandamide (AEA)) were also tested. Propranolol (β-adrenergic antagonist) and WAY-100635 (5-HT1A antagonist) attenuate HPA activation by cannabinoids and, therefore, were assessed. In humans, CHS symptoms are not alleviated by anti-emetic drugs, such as ondansetron (5-HT3 antagonist); however, benzodiazepines are effective. Therefore, ondansetron and chlordiazepoxide were tested. To determine if HPA activation by THC is dose-dependent, corticosterone (CORT) was analyzed from serum of rats treated with 0.0, 0.5, or 10 mg/kg THC. RESULTS Antalarmin (10 and 20 mg/kg), MJN110 (10 mg/kg), URB597 (0.3 mg/kg), propranolol (2.5 and 5 mg/kg), WAY-100635 (0.5 mg/kg), and chlordiazepoxide (5 mg/kg) interfered with THC-induced conditioned gaping, but the anti-emetic ondansetron (0.1 and 0.01 mg/kg) did not. THC produced significantly higher CORT levels at 10 mg/kg than at 0.0 and 0.5 mg/kg THC. CONCLUSIONS Treatments that interfere with the stress response also inhibit THC-induced conditioned gaping, but a typical anti-emetic drug does not, supporting the hypothesis that THC-induced nausea, and CHS, is a result of a dysregulated stress response.

Abstract
The sale of cannabis for adult recreational use has been made legal in nine US states since 2012, and nationally in Uruguay in 2013 and Canada in 2018. We review US research on the effects of legalization on cannabis use among adults and adolescents and on cannabis-related harms; the impact of legalizing adult recreational use on cannabis price, availability, potency and use; and regulatory policies that may increase or limit adverse effects of legalization. The legalization of recreational cannabis use in the US has substantially reduced the price of cannabis, increased its potency, and made cannabis more available to adult users. It appears to have increased the frequency of cannabis use among adults, but not so far among youth. It has also increased emergency department attendances and hospitalizations for some cannabis-related harms. The relatively modest effects on cannabis use to date probably reflect restrictions on the number and locations of retail cannabis outlets and the constraints on commercialization under a continued federal prohibition of cannabis. Future evaluations of legalization should monitor: cannabis sales volumes, prices and content of tetrahydrocannabinol; prevalence and frequency of cannabis use among adolescents and adults in household and high school surveys; car crash fatalities and injuries involving drivers who are cannabis-impaired; emergency department presentations related to cannabis; the demand for treatment of cannabis use disorders; and the prevalence of regular cannabis use among vulnerable young people in mental health services, schools and the criminal justice system. Governments that propose to legalize and regulate cannabis use need to fund research to monitor the impacts of these policy changes on public health, and take advantage of this research to develop ways of regulating can-nabis use that minimize adverse effects on public health.

Abstract
Introduction: Cannabinoid hyperemesis syndrome (CHS) is a disorder of cyclic and recurrent nausea, vomiting, and abdominal pain associated with high-frequency and extended-duration marijuana use. Standard antiemetic therapy is often ineffective; however, capsaicin, an agonist of transient receptor potential vanilloid 1 (TRPV1), has shown promise in treating CHS.Methods: This retrospective cohort analysis evaluated the safety and efficacy of topical capsaicin for patients presenting with CHS. The primary outcome was to assess if utilization of capsaicin for ED management of CHS decreased ED length of stay (LOS) as compared to a visit without capsaicin. Secondary outcomes included a cost analysis, use of rescue therapies, and adverse events.Results: Forty-three patients met the inclusion criteria within the study period. ED LOS was reduced with capsaicin by a median of 22 minutes (201 vs. 179 min, p = 0.33). Patients received fewer additional medications if capsaicin was utilized (4 vs. 3 doses, p = 0.015), and 67% of visits where capsaicin was utilized required no further treatment prior to discharge. Additionally, opioid usage was less when utilizing capsaicin (166.5 vs. 69 mg OME). Forty-two percent of patients did not have a repeat CHS presentation to the ED after receiving capsaicin for an additional three months after the study period ended. Total medication cost was minimally more expensive (median difference of $3.26) in the capsaicin group. There were no significant adverse events reported with capsaicin.Conclusion: There was no significant difference in ED LOS when capsaicin was utilized for CHS. However, there was a decrease in total medications administered and a reduction in opioid requirements. While medication costs for capsaicin visits were minimally more expensive, the utility of capsaicin as an over-the-counter (OTC) product may empower at home therapy with OTC products, decreasing potentially unnecessary healthcare encounters and costs.

Abstract
Objective: Cannabinoid hyperemesis syndrome (CHS) is characterized by cyclic vomiting, abdominal pain, and alleviation of symptoms via hot showers in chronic cannabinoid users. Capsaicin is recommended as a reasonable first-line treatment approach for CHS despite limited clinical evidence regarding its use. The objective of this study is to systematically review the efficacy data for capsaicin in CHS. Data Sources: A literature search using keywords related to cannabinoids, emesis, and capsaicin was performed in MEDLINE, CINAHL, and EMBASE from inception through March 31, 2019. Study Selection and Data Extraction: Studies and published abstracts in which capsaicin was used for CHS and clinical outcomes were reported were eligible for inclusion. Data Synthesis: A total of 241 articles were screened, of which 5 full-text articles and 6 conference abstracts were included. Full-text case reports (n = 3) and case series (n = 2) found capsaicin to be effective in a total of 18 patients. Published abstracts were in the form of case reports (n = 1), case series (n = 3), and retrospective cohort studies (n = 2). Relevance to Patient Care and Clinical Practice: Capsaicin use was described as beneficial in all case series and case reports; however, both retrospective cohort studies were unable to find a significant benefit for capsaicin on primary outcomes (emergency department length of stay). Conclusion: Current data for capsaicin efficacy in CHS is of low methodological quality. However, the limited data on alternative antiemetic therapies and capsaicin’s favorable risk-benefit profile make it a reasonable adjunctive treatment option.

Abstract
Background. Chronic cannabis use has become prevalent with decriminalization, medical prescription, and recreational legalization in numerous US states. With this increasing incidence of chronic cannabis use a new clinical syndrome has become apparent in emergency departments and hospitals across the country, termed Cannabinoid Hyperemesis (CH). CH has been described as cyclical vomiting and abdominal pain in the setting of chronic cannabis use, which is often temporarily relieved by hot showers. CH presents a diagnostic challenge to clinicians who do not have a high clinical suspicion for the syndrome and can result in high costs and resource utilization for hospitals and patients. This study investigates the expenditures associated with delayed CH evaluation and delayed diagnosis. Methods. This is a retrospective observational study of 17 patients diagnosed with CH at three medical centers in the United States from 2010 to 2015, consisting of two academic centers and a community hospital. Emergency department (ED) costs were calculated and analyzed for patients eventually diagnosed with CH. Results. For the 17 patients treated, the total cost for combined ED visits and radiologic evaluations was an average of $76,920.92 per patient. On average these patients had 17.9 ED visits before the diagnosis of CH was made. Conclusion. CH provides a diagnostic challenge to clinicians without a high suspicion of the syndrome and may become increasingly prevalent with current trends toward cannabis legalization. The diagnosis of CH can be made primarily through a thorough history and physical examination. Awareness of this syndrome can save institutions money, prevent inappropriate utilization of healthcare resources, and save patients from unnecessary diagnostic tests.

Abstract
Cannabinoid hyperemesis syndrome (CHS) is a paradoxical condition in which a long-term cannabis user suffers an episode of intractable vomiting that may last days separated by longer asymptomatic periods of weeks or months. Cannabinoids are often utilized for their antiemetic properties, so CHS can be a puzzling condition, and the diagnosis of CHS may be disputed by patients. Unlike other cyclic vomiting syndromes, CHS can be relieved by hot showers or topical capsaicin. Abstinence from cannabinoids causes CHS to resolve, sometimes in a matter of days or hours. Marijuana users as well as many clinicians are not aware of CHS, and patients may undergo unnecessary tests, scans, and other procedures to get an accurate diagnosis. Symptoms may be severe enough to require hospitalization. With liberalization of marijuana laws and favorable public opinion about the healing properties of cannabis, CHS may be more frequently observed in clinical practice.
