Abstract Purpose To characterize cannabis use among cancer patients, we aimed to describe 1) patterns of cannabis use across multiple cancer sites; 2) perceived goals, benefits, harms of cannabis; and 3) communication about cannabis. Methods Patients with 9 different cancers treated at Memorial Sloan Kettering Cancer Center between March and August 2021 completed an online or phone survey eliciting cannabis use, attitudes, and communication about cannabis. Multivariable logistic regression estimated the association of cancer type and cannabis use, adjusting for sociodemographic characteristics and prior cannabis use. Results Among 1258 respondents, 31% used cannabis after diagnosis, ranging...

Furthermore, we sought to assess efficacy of medical cannabis for the treatment of pain, nausea, anorexia, insomnia and anxiety in elderly cancer patients. Background Medical cannabis use is growing for symptom management in cancer patients, but limited data exists on the safety or efficacy of use in elderly patients. Methods A retrospective chart review assessing changes in numerical symptom scores reported at clinic visits before and after medical cannabis initiation. Results There was no statistically significant difference in pain,...

Abstract Objectives:  Cancer patients are using medical cannabis (MC) to address symptoms; however, little data exist to guide clinicians when counseling patients. We seek to define the patterns of MC use among cancer patients, as well as efficacy and safety of MC. Materials and Methods:  Cancer patients attending oncology office visits at Beaumont Hospital, Michigan from July to December 2018 were anonymously surveyed. The survey included data regarding demographics, diagnosis, treatment, symptom burden, and MC use. Patients who reported MC use since their cancer diagnosis completed a section on patterns of use, efficacy, and safety. Results: ...

Abstract Background National studies reporting the prevalence of cannabis use have focused on individuals with a history of cancer without distinction by their treatment status, which can impact symptom burden. While pain is a primary motivation to use cannabis in cancer, the magnitude of its association with cannabis use remains understudied. Methods We examined cannabis use and pain management among 5523 respondents of the Behavioral Risk Factor Surveillance System with a cancer history. Survey-weighted prevalence proportions of respondents’ cannabis use are reported, stratified on cancer treatment status. Regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs) of cancer-related pain and cannabis use....

Recent legislative changes in Australia have increased access to medicinal cannabis, but the views of people with cancer on this topic are poorly understood. The aim of this study was to explore the prevalence of the use of and attitudes towards medicinal cannabis among people with cancer. Methods A cross-sectional study was performed using an anonymous, 15-item study-specific paper-based survey. The survey was administered over a 2-week period in August 2017 in the waiting rooms of a specialist cancer hospital. Results In all, 339...

Objectives The study sought to assess factors contributing to the demand for MC among patients with cancer. Methods Patients applying for a permit to receive MC at a pain and palliative clinic of a university-affiliated cancer center in Israel in 2020–2021 were asked to complete self-report questionnaires assessing attitudes, knowledge, and expectations regarding MC use. Findings were compared between first-time and repeat applicants. Repeat applicants were asked to report their indications for requesting MC, patterns of use, and treatment effect. Results The cohort included 146...

Abstract Background As more states legalize cannabis for medical and recreational use, people increasingly use cannabis to treat medical conditions and associated symptoms. The prevalence and utility of cannabis for cancer-related symptoms may be clarified by examining cannabis use among patients with a common cancer diagnosis. We aimed to determine the prevalence of cannabis use among colorectal cancer (CRC) survivors and its associations with quality of life (QoL) and cancer-related symptomatology. Methods A cross-sectional survey of patient-reported QoL outcomes and behaviors, including cannabis use, was conducted within the Patient Outcomes To Advance Learning network’s (PORTAL) CRC Cohort. The cohort included a population-based sample of...

Abstract Symptoms such as pain, nausea, and anxiety are common in individuals with cancer. Treatment of these issues is often challenging. Cannabis products may be helpful in reducing the severity of these symptoms. While some studies include data on the prevalence of cannabis use among patients with cancer, detailed data remain limited, and none have reported the prevalence of cannabidiol (CBD) use in this population. Adult patients with cancer attending eight clinics at a large, NCI-designated Comprehensive Cancer Center completed a detailed, cannabis-focused questionnaire between 2021 and 2022. Eligible participants were diagnosed with invasive cancer and treated in the past 12 months. Summary statistics...

Abstract Objectives: To examine the proportion of individuals using cannabis for medical purposes who reported nonmedical use of cannabis after it became legal to do so. Materials and Methods: We acquired data from the Population Assessment for Tomorrow's Health, the Cannabis Legalization Surveillance Study on a subpopulation of participants residing in Hamilton, Ontario, Canada, who reported using cannabis for medical purposes. Specifically, we acquired data 6 months before, and again 6 months after, legalization of cannabis for nonmedical purposes. We constructed a logistic regression model to explore the association between potential explanatory factors and endorsing exclusively nonmedical use after...

Abstract Introduction: This study examines age, time period and birth cohort trends in cannabis use intention and weekly use in Australia over a period in which medicinal cannabis was legalised. Methods: Hierarchical age-period-cohort models were used to analyse the National Drug Strategy Household Survey between 2001 and 2019, including 158,395 participants aged 18-79 years. Results: The hierarchical age-period-cohort model demonstrated a decrease in likelihood of intending to try cannabis as age increases. Similar age effects were found in intending to use cannabis as often or less often. There was broad-based shift in attitudes for people wanting to try cannabis (2007: b = -0.51 [-0.82, -0.21]; 2019: b...
