The historical use of Cannabis for both medicinal and recreational purposes suggests it to be a friendly plant. However, whether the misuse of Cannabis and the cannabinoids derived from it can hamper normal body physiology is a focus of ongoing research. On the one hand, there is enough evidence to suggest that misuse of marijuana can cause deleterious effects on various organs like the lungs, immune system, cardiovascular system, etc. and also influence fertility and cause teratogenic effects. However, on the other...

ABSTRACT Objectives: The principal objective of our study was to document the short-term impact of the legalization of recreational cannabis on active cannabis use, cannabis use disorder, and various psychotic disorders. Methods: We carried out a retrospective observational study of patients who were at least 12 years old and who had visited a psychiatrist in the emergency unit of the Centre hospitalier universitaire de Sherbrooke (CHUS). We included all the consultations of this type over a 5-month period, immediately following the legalization of recreational cannabis in Canada. We then divided our population into an adult (over 18) and teenager group (12 to 17) compared the data...

The aim of this exploratory observational study was to compare rates of cannabis use, cigarette smoking, alcohol consumption, and the use of any street drugs during the preconception period and in pregnancy in two convenience samples of pregnant persons in British Columbia, Canada, before and after the legalization of cannabis. Methods Any pregnant person residing in British Columbia, aged >19 years, at any gestational age was eligible to participate. Pre- and post-legalization study participants were recruited between May and...

Abstract Background: Cannabis use is increasing among young adults, but its effects on cardiovascular health are poorly understood. We aimed to assess the association between recent cannabis use and history of myocardial infarction (MI) in young adults (aged 18–44 yr). Methods: We performed a cross-sectional study using pooled data from the 2017 and 2018 cohorts of the American Behavioral Risk Factor Surveillance System survey of US adults. We analyzed the association between any recent cannabis use and history of MI using a weighted logistic regression model that adjusted for demographic factors, socioeconomic factors, health-related behaviours, concomitant substance use and other comorbidities. We also assessed this association...

Abstract Background Legalization of medical and recreational cannabis in US states has been accompanied by increases in availability, acceptability, and diversity in methods of cannabis use, as well as an increase in devices and methods for cannabis-tobacco co-use. Updated and specific survey measures of cannabis and cannabis-tobacco co-use are needed. Methods We employed a mixed-methods approach to identify sources of specification and measurement error in cannabis and cannabis-tobacco co-use measures. We surveyed and interviewed 36 young adult (age 18–29) cannabis and tobacco co-users in California (2017-2018), triangulated with document analysis of online cannabis websites and forums. We investigated how survey reports of cannabis use...

ABSTRACT Objectives: Although the rate of cannabis use by older adults is increasing more quickly than all other age groups, little is known about the reasons older adults use cannabis and the outcomes they experience. With this research, we investigated older adults’ perceptions and experiences of medical cannabis use to treat and/or manage chronic conditions, specifically as a substitute for prescription drugs. Methods: Researchers relied on qualitative inquiry in the form of semi-structured, one-on-one interviewing to investigate the phenomenon of medical cannabis use for the management of chronic conditions. Results: Our findings suggest that older adults...

This study examined the prevalence and correlates of self-reported MCU among adolescents. Methods Secondary school students (grades 9–12; N = 3,221) completed a cross-sectional survey in classrooms across Ontario, Canada, in 2016–2017. Participants reported on cannabis use behavior, cannabis dependence, other drugs use, and general health and sleep. Participants reporting cannabis use in the past year were grouped based on whether they reported MCU or not (i.e., recreational cannabis use only [RCU-only]). Results An estimated 6.89% (95% confidence interval 5.48%–8.63%) of students reported MCU, representing one quarter of the students reporting current...

Abstract Objectives To evaluate medical marijuana patients’ perceptions of therapeutic benefits for self-reported medical conditions. Design The study was a concurrent mixed methods study with adult medical marijuana patients. Survey data were collected using a web-based survey, and interviews were conducted in person or over the phone. Setting The study recruited 196 medical marijuana patients to complete surveys and 13 patients to participate in qualitative interviews in Florida. Measures A validated patient survey was distributed via Florida medical marijuana social media groups to examine the therapeutic benefits of the cannabis plant for medical conditions and overall well-being. Concurrently, qualitative interviews were conducted to understand...
