Abstract Session 2 of the National Cancer Institute’s Cannabis, Cannabinoids, and Cancer Research Workshop opened with testimony from a lymphoma survivor who detailed medicinal cannabis-related improvements in nausea, low appetite, insomnia, and mental health and the limited clinical counsel she received regarding cannabis use. Discussion next turned to the evolution of the legal landscape of cannabis in the United States, one in which state and federal laws frequently conflict and the Controlled Substance Act renders cannabis Schedule I. This legal climate creates conundrums for US medicinal cannabis researchers who contend with limited funding opportunities, avenues to source trial drug, and procedural red tape and...

Abstract Background The relevance of medical cannabis (MC) increases; and, educating those who are at the forefront of patient care is imperative. Yet, research on medical students’ expertise and opinions is still scarce. Objective This study set out to evaluate Austrian medical students’ knowledge about and attitudes towards MC and compare them with other academic disciplines. Additionally, gender was controlled for. Methods An online survey was conducted with N = 404 students enrolled in (1) medical studies, (2) studies with a medical background and (3) studies without a medical background. Results In contrast to non-medical students, 64 % of medical students said they learnt about MC...

Design Population-based, retrospective cohort study. Setting California, USA. Participants A total of 4.83 million mothers who delivered a live singleton birth during 2001 to 2012 and their paired infants.

Abstract Background Despite increases in cannabis use generally and for pain management, data regarding cannabis use in patients undergoing surgery are lacking. This study examined the prevalence of cannabis use among patients undergoing elective surgery and explored differences in clinical characteristics and surgical outcomes between cannabis users and non-cannabis users. Methods This prospective study included 1335 adults undergoing elective surgery. Participants completed self-report questionnaires preoperative and at 3-month and 6-month postsurgery to assess clinical characteristics and surgical outcomes. Results Overall, 5.9% (n=79) of patients reported cannabis use (53.2% medical, 19.0% recreational and 25.3% medical and recreational). On the day...

Abstract Aim Cannabis-based medicinal products (CBMPs) are prescribed with increased frequency, despite a paucity of high-quality randomized controlled trials. The aim of this study is to analyze the early outcomes of the first series of patients prescribed CBMPs in the UK with respect to effects on health-related quality of life and clinical safety. Methods A prospective case series was performed using the UK Medical Cannabis Registry. Primary outcomes were change in patient-reported outcomes measures (EQ-5D-5L, General Anxiety Disorder-7 (GAD-7) and Single-Item Sleep Quality Scale (SQS)) at 1 and 3 months from baseline. The secondary outcome was the incidence of adverse events. Statistical significance was defined...

Abstract The outbreak of e-cigarette or vaping product use-associated lung injury (EVALI) has been cause for concern to the medical community, particularly given that this novel illness has coincided with the COVID-19 pandemic, another cause of severe pulmonary illness. Though cannabis e-cigarettes tainted with vitamin E acetate were primarily associated with EVALI, acute lung injuries stemming from cannabis inhalation were reported in the literature prior to 2019, and it has been suggested that cannabis components or additives other than vitamin E acetate may be responsible. Despite these concerning issues, novel cannabis vaporizer ingredients continue to arise,...

The objective was to evaluate the association of a cannabis-related diagnosis (CRD) in pregnancy and adverse maternal and infant outcomes. Methods We queried an administrative birth cohort of singleton deliveries in California between 2011–2017 linked to maternal and infant hospital discharge records. We classified pregnancies with CRD from International Classification of Disease codes. We identified nicotine and other substance-related diagnoses (SRD) in the same manner. Outcomes of interest included maternal (hypertensive disorders) and infant (prematurity, small for gestational age, NICU...

This study examined changes in cannabis use over the following year in a sample of general community adults. A secondary aim was to examine forecasted cannabis use following legalization in relation to actual post-legalization cannabis use. Methods Participants were 1502 community adults (61 % female; age M = 34.60 ± 13.95), with approximately half reporting any cannabis use in the six months prior to legalization (Cannabis+ group [48 %]/Cannabis− group [52 %]). Self-report assessments were conducted in the month before cannabis legalization, 6-months post-legalization and 12-months...

Abstract Background The legalization of cannabis is expanding across the USA, and its use has increased significantly, including among Veterans. Although the Veterans Health Administration (VHA) abides by the classification of cannabis as a Schedule I substance, it recently recommended that clinicians discuss cannabis with their patients. Little is known about VHA clinicians’ perspectives on and knowledge of cannabis. Objective We sought to better understand clinicians’ attitudes, beliefs, knowledge and communication with patients regarding cannabis. Methods We conducted semi-structured phone interviews with 14 VHA clinicians. Interviews were audio-recorded, transcribed verbatim and analysed using qualitative thematic analysis. Results VA clinicians described ambivalence towards cannabis for...

Abstract Hemp (Cannabis sativa L.) is a herbaceous anemophilous plant that belongs to the Cannabinaceae family. The cannabis seed (hemp) has long been utilized as a food source and is commercially important as an edible oil source. In this review, the positive and negative health effects of cannabis, the relationship between cannabis and various diseases, and the use of cannabis in various food products have been discussed. In addition, the scientific literature on the potential use of cannabis and its derivatives as a dietary supplement for the prevention and treatment of inflammatory and chronic degenerative diseases in animals and humans has been reviewed. Cannabis is...
