Abstract Background Cancer patients have been at the forefront of policy discussions leading to legalization of medical Cannabis (marijuana). Unfortunately, Cannabis use among those with cancer is poorly understood. Methods A diverse group of patients seeking certification for medical Cannabis in the state of Michigan were surveyed at the time of their presentation to medical dispensaries. The survey assessed demographics, employment/disability, pain, physical functioning, mental health, mode of Cannabis use, and frequency/amount of Cannabis use. Chi-square and t-tests were performed to compare those who did and did not endorse cancer diagnosis. Results Analysis of data from 1485 adults pursuing medical Cannabis certification, including 72...

Abstract Objective: Research suggests African American men use cannabis to cope with racial discrimination. This conjecture may also be true for incarcerated African American men, who report high rates of cannabis use prior to and after incarceration. However, no studies to date have examined the association between race-related stress and chronic cannabis use among incarcerated African American men. As this population encounters pervasive negative cultural stereotypes and devaluation from larger society, cultural race-related stress may predict cannabis use among this population. Therefore, the purpose of this brief report was to examine the relationship between cultural race-related stress and years of regular cannabis use among...

Abstract Introduction Despite increasing consumption rates in much of the world, the impact of cannabis use on various components of male sexual function remains poorly established. The purpose of this study was to further evaluate the relationship between cannabis use and reproductive and sexual function using a large patient cohort from a single academic andrology clinic. Methods This is a historical cohort study from a single academic center andrology clinic. Patients from 2008–2017 were included. Intake questionnaires provided baseline demographic information, as well as data regarding substance use and various sexual function parameters. Subjects were categorized as cannabis users or non-users. Cannabis users and...

Nevertheless, the evidence for cardiovascular safety of cannabis use is scarce. The aim of this study was to assess the effect of cannabis on blood pressure, heart rate, and metabolic parameters in older adults with hypertension. Methods: We conducted a prospective study of patients aged 60 years or more with hypertension and a new prescription of cannabis. We have performed the following assessments: 24-hours ambulatory blood pressure monitoring, ECG, blood tests, and anthropometric measurements prior to the initiation of cannabis therapy and 3 months...

Abstract Cannabis has certain health benefits, but some people may experience harms from use. Co-use of tobacco and cannabis is common. Smoke from cannabis contains many of the same carcinogens and toxicants as the smoke from tobacco, raising concerns that cannabis smoking may be a risk factor for cancer. With growing access to and acceptance of medical and nonmedical cannabis, there is an urgent need to understand the risks and benefits of the current modes of cannabis use and how cannabis may be associated with cancer risk. This monograph summarizes a session from a National Cancer Institute Symposium on nonmedical cannabis use and cancer...

Abstract Summary In many countries, liberalisation of the legislation regulating the use of cannabis has outpaced rigorous scientific studies, and a growing number of patients presenting for surgery consume cannabis regularly. Research to date suggests that cannabis can impact perioperative outcomes. We present recommendations obtained using a modified Delphi method for the perioperative care of cannabis-using patients. A steering committee was formed and a review of medical literature with respect to perioperative cannabis use was conducted. This was followed by the recruitment of a panel of 17 experts on the care of cannabis-consuming patients. Panellists were blinded to each other's participation and were provided with rater forms exploring...

Abstract Heavy exposure to cannabis during adolescence can cause significant neurocognitive changes. It can alter emotional responsiveness and social behavior, and cause impairments in sustained attention, learning, working memory (WM), cognitive flexibility, and the speed of information processing. It also has a significant impact on executive functions. In this study we investigated how global cognitive functions can be affected by the frequency of cannabinoid consumption in different categories of consumers (chronic, occasional, and non-users), through the evaluation of executive functions. Statistical analysis showed a significant decrease in performance in working memory tasks and processing speed by subjects using cannabis chronically (group 1) as compared...

Abstract Background Medical cannabis may be a useful tool for managing treatment-resistant epilepsy and chronic pain, which affect many patients in pediatric palliative care (PPC); however, little evidence is available in this setting. Case presentation We aimed to describe a clinical experience in a setting where high-level evidence may not be obtained. We report our clinical experience in a pediatric palliative care department in Italy. Caregivers reported changes in intensity and frequency of pain and epilepsy events. Six patients received a titrated plant extract of cannabis sativa for 1 year. Only mild and transient adverse events occurred: drowsiness, euphoria, restlessness and tachycardia; the resolution was either spontaneous...

Although there are established measures of cannabis expectancies, existing measures have psychometric limitations and/or are lengthy. Existing measures typically have a two-factor structure of positive and negative expectancies, but recent conceptualizations of alcohol expectancies support a valence- (positive vs. negative) and arousal-based (high vs. low arousal) structure. Thus, the present study sought to test a similar structure for cannabis. Cannabis expectancy items underwent 2 preliminary studies, assessing item valance/arousal (n = 233) and relevance to cannabis (n = 124). A final pool of 76...

Abstract Background The use of cannabinoids in mental health has gained strength in recent years due to emerging scientific evidence and the lifting of prohibitionist laws that prevailed for years in many countries, including Colombia. This study describes the results of a survey of Colombian psychiatrists on some aspects of medicinal cannabis, such as attitudes towards its potential use, perceived knowledge, and beliefs surrounding its regulation and safety. Methods We conducted a cross-sectional survey of 145 psychiatrists in 14 territories of Colombia between November 2019 and July 2020. The survey consisted of 28 items on topics related to medicinal cannabis, including attitudes and clinical...
