Non-medical cannabis use among Indigenous Canadians: A systematic review of prevalence and associated factors

Background: To investigate the hypothesis that cases of arteritis similar to thromboangiitis obliterans (TAO) and associated with the use of cannabis were caused by cannabis or THC (dronabinol), or that cannabis use is a co-factor of TAO. Patients and methods: A systematic review on case reports and the literature on so-called cannabis arteritis, TAO, and cardiovascular effects of cannabinoids was conducted. Results: Fifteen reports with 57 cases of an arteritis associated with the use of cannabis and two additional case series of TAO, in which some patients also used cannabis, were identified. Clinical and pathological features of cannabis-associated arteritis do not differ from TAO and the major risk factor of TAO, tobacco use, was present in most, if not in all of these cases. The proposed pathophysiological mechanisms for the development of an arteritis by cannabis use are not substantiated. Conclusions: The hypothesis of cannabis being a causative factor or co-factor of TAO or an arteritis similar to TAO is not supported by the available evidence. The use of the term cannabis arteritis should be avoided until or unless more convincing scientific support is forthcoming.

Lower Baseline

Although researchers have identified medications that relieve symptoms of multiple sclerosis (MS), none are entirely effective and some persons with multiple sclerosis (PwMS) use alternatives. Our study compared cannabis use among PwMS (N = 135) and persons diagnosed with arthritis (N = 582) or cancer (N = 622) who were age 60 and older, enrolled in the State of Illinois Medical Cannabis Program, and invited to complete a survey fielded between June and September, 2019. We used logistic regression to identify significant differences in self-reported effects of cannabis on psychological wellbeing, quality of life, and three behavioral outcomes, and we also considered effects of past year opioid use relative to these outcomes. We found that the majority of individuals from all groups used cannabis to address pain and improve quality of sleep. While PwMS reported lower baseline levels across all five outcomes, we found that the reported effects of cannabis were largely comparable across the groups. We also found that cannabis benefitted persons with sleep and digestive issues regardless of condition, whereas persons who used opioids in addition to cannabis were less likely to experience an improvement in any of the outcomes. This comparative evaluation suggests that cannabis’ effects are not specific to MS, arthritis, or cancer as much as they impact processes common among these distinct conditions. We also found evidence that cannabis may be a viable alternative to opioids for those with these conditions and experiencing pain.

Abstract Background Preconception care is the provision of biomedical, behavioural, and social health interventions provided to women and couples before conception. However, in Ethiopia, little is known and practised to support preconception care. Therefore, this study aimed to assess women’s knowledge and utilisation of preconception care and its associated factors in Ethiopia using systematic review and meta-analysis. Method In the current meta-analysis, variables were searched from different electronic database systems, which included PubMed, Google Scholar, EMBASE, HINAR, Scopus, Web of Sciences, and Grey literature. Data were extracted using a standardised data collection measurement tool. The data were analysed by using STATA 14 statistical software. I2 tests assessed heterogeneity between the studies. A random-effect model was used to forecast the pooled knowledge and utilisation of preconception care. Results Thirteen full-text studies were included. The pooled prevalence of knowledge and utilisation of preconception care among women in Ethiopia was 30.95% and 16.27% respectivelly. Secondary education (OR = 2.78, 95% CI,2.01–3.85), college and above (OR = 5.05, 95% CI,2.70–9.44), and antenatal care (OR = 3.89, 95% CI, 1.69–8.98) were significantly associated with knowledge level whereas; age (OR = 2.43, 95% CI, 1.30–4.53) and knowledge on preconception care (OR = 3.95, 95% CI,2.35–6.62) were positively associated with utilisation of preconception. Conclusions Women’s level of knowledge and utilisation of preconception care was significantly low. Educational status and antenatal care follow-up were factors shown to affect knowledge of preconception care. Age and having a sound knowledge of preconception care indicated a significant association towards utilisation of preconception care. Thus, integrating preconception care strategies and policies that can address all the components of preconception care services with other maternal and child health services will be essential when designing effective implementation strategies to improve preconception care uptake. Besides this, advocating for better education for women, awareness creation, and increasing antenatal care services are essential. Prospero registration: CRD42020218062
