Abstract Introduction Cannabis consumption during pregnancy increases the risk of pregnancy and neonatal complications. Since the underlying mechanism is unknown, the purpose of this study is to evaluate the changes in maternal and fetal blood flow in pregnancies exposed to cannabis, Δ9-tetrahydrocannabinol (THC). Material and methods A case–control study between 2013 and 2020, included women with continued cannabis exposure during the pregnancies, defined by qualitative detection of THC in urine (Cannabis Group), and low-risk pregnancy women divided into tobacco smokers (Tobacco Group), and non-tobacco smokers (Control Group). We evaluated the association between cannabis consumption and maternal and fetal blood flow parameters measured by Doppler...

Abstract Cannabis and cannabis-derived products are increasingly used for recreational and medical purposes including anxiety and epilepsy and are often concurrently used with other types of conventional medications. The concomitant use of cannabis with other therapeutic drugs has been shown to increase the likelihood of deleterious drug-drug interactions. Oxazepam is a well-known benzodiazepine used in clinical practice as an anxiolytic, sedative, and anticonvulsant agent. Oxazepam is a racemic mixture of the S-and R-enantiomers and is primarily metabolized via glucuronidation in an enantiomeric-specific manner, where S-oxazepam is mainly glucuronidated by UDP-glucuronosyltransferase (UGT) 2B15 and R-oxazepam is glucuronidated...

Abstract Cannabis (marijuana) is the most commonly used illicit product in the world and is the second most smoked plant after tobacco. There has been a rapid increase in the number of countries legalizing cannabis for both recreational and medicinal purposes. Smoking cannabis in the form of a joint is the most common mode of cannabis consumption. Combustion of cannabis smoke generates many of the same chemicals as tobacco smoke. Although the impact of tobacco smoke on respiratory health is well-known, the consequence of cannabis smoke on the respiratory system and, in particular, the inflammatory response is unclear. Besides the combustion products present in...

Abstract Cannabis is one of the most widely consumed recreational drugs among reproductive aged adults around the globe. It is known that Δ-9-tetrahydrocannabinol (THC), the psychoactive component of cannabis, can interact with the endocannabinoid system (ECS) via cannabinoid receptor 1. Components of the ECS are highly involved in regulating mammalian reproductive processes such as oocyte, sperm, and embryo development by modulating gene expression, apoptosis, and several intracellular pathways. Previous research in our lab demonstrated that THC exposure to bovine oocytes, the ideal translational model for human, was detrimental to in vitro maturation, increased apoptosis in blastomeres and altered gene expression (Misner et al., 2021)....

Abstract Background Neuropathic pain and other pain disorders have received attention as potential indications for use of cannabis-based medicines or medical cannabis (CBM/MC). Evidence regarding the efficacy and safety of CBM/MC for pain disorders is, however, insufficient. Denmark introduced a pilot programme of medical cannabis in January 2018. We aimed to evaluate efficacy, safety, and non-specific effects of CBM/MC used under the pilot programme compared with controls. Methods We conducted a nationwide register-based cohort study in Denmark, identifying all individuals redeeming at least one prescription for CBM/MC for either neuropathic pain (n = 1817) or other and unspecified...

Please use this link to access this publication. Purpose of review This review aims to summarize recent updates in the area of cannabis use for insomnia. Recent findings Cannabis products have continued to become more potent, particularly in regard to delta-9- tetrahydrocannabinol (THC) concentration. Additionally, the use of cannabis has continued to become more accepted with less legal restrictions. The reported use of cannabis for relief of symptoms in sleep disorders appears to be increasing, however the specific effects of cannabinoids on sleep varies with cannabinoid type and concentration. Some evidence supports claims of efficacy of cannabinoids in sleep disorders such as insomnia, while...

Abstract Inflammation often develops from acute, chronic, or auto-inflammatory disorders that can lead to compromised organ function. Cannabis (Cannabis sativa) has been used to treat inflammation for millennia, but its use in modern medicine is hampered by a lack of scientific knowledge. Previous studies report that cannabis extracts and inflorescence inhibit inflammatory responses in vitro and in pre-clinical and clinical trials. The endocannabinoid system (ECS) is a modulator of immune system activity, and dysregulation of this system is involved in various chronic inflammations. This system includes cannabinoid receptor types 1 and 2 (CB1 and CB2), arachidonic acid-derived endocannabinoids, and enzymes involved in endocannabinoid metabolism. Cannabis produces...

Abstract Nonmedical (“recreational”) cannabis use and cannabis laws have changed over the past two decades in the United States (1) and the rest of the world (2). Increasing use, especially among the young, coupled with the increasing potency of cannabis (higher delta-9-tetrahydrocannabinol [THC] content) during this period (3), has raised concerns about the long-term health impact of cannabis exposure, especially among adolescents and young adults. There is recognition of an association between cannabis use and psychosis, but whether the relationship is causal continues to be debated. One rebuttal raised in this debate is that if cannabis caused psychosis, then the increases in the rates...

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...

Abstract Introduction: As cannabis use continues to increase in popularity, it is important to investigate how it impacts public health in all sectors of the population, including patients undergoing anesthetic management. This retrospective study focuses on the orthopedic trauma population presenting through an emergency department (ED) and receiving a urine drug screen (UDS) with subsequent urgent surgical intervention. We aimed to evaluate differences in response to general anesthesia in patients with exposure to THC, a major cannabinoid, compared to controls that screened negative for THC. Materials and Methods: All ED visits at UC Irvine, a level 1 trauma center between November 4, 2017 and January 7,...
