Abstract Cannabis use by women has been under-researched, particularly use by marginalized women in developing societies. This article draws on qualitative research in Uyo, Nigeria, to explore how intersecting stigmas around social identity categories (e.g. gender, sex work) shapes cannabis use and contributes to health harms for marginalized women. Qualitative data were collected via in-depth interviews with street-involved female cannabis users, and transcribed, coded and analysed thematically. Initiation of cannabis use was influenced by social networks and sexual relationships. Heavy cannabis use enabled some women to perform alternative femininity thereby challenging the boundaries of appropriate gendered behaviour, while others were pressured by normative expectations...

Abstract This study was done to investigate the effect of roasting time (7, 14, and 21min) at 160 ᵒC on proximate composition, colour attributes, bioactive compounds, and fatty acids composition of hemp (Cannabis sativa L.) seeds. Roasting of the seeds for different periods significantly (P < 0.05) increased the protein, oil, total phenolic, total flavonoid, and DPPH scavenging. The lightness (L*) and yellowness (b*) of the samples were significantly (P < 0.05) decreased with roasting time but redness (a*) was increased. Moreover, phenolic acids, flavones, polyphenols, and glycosylated flavonoids were increased significantly with the roasting time. Roasting of the seed slightly affected fatty acid contents....

Previous work suggests that older adults are inclined to stick to the more “classic” and familiar, while “novel” products are more likely to appeal to younger populations. We examined cross-sectional, retrospective data to determine whether the type of cannabis products used varied according to participant age (N = 1406, 71.3% female). The extensive list of products included: loose flower, pre-rolled joints, edibles, concentrates, oil vaporizers (vape pens), dry vaporizers, tinctures, topicals, and ingestible oils. Overall, rates of use for cannabis-infused ingestible...

Abstract Cannabis and cannabinoids are implicated in multiple genotoxic, epigenotoxic and chromosomal-toxic mechanisms and interact with several morphogenic pathways, likely underpinning previous reports of links between cannabis and congenital anomalies and heritable tumours. However the effects of cannabinoid genotoxicity have not been assessed on whole populations and formal consideration of effects as a broadly acting genotoxin remain unexplored. Our study addressed these knowledge gaps in USA datasets. Cancer data from CDC, drug exposure data from National Survey of Drug Use and Health 2003–2017 and congenital anomaly data from National Birth Defects Prevention Network were used. We show that cannabis, THC cannabigerol and cannabichromene exposure...

Abstract Previous studies have demonstrated improvements in pain following short-term medical cannabis (MC) use, suggesting long-term MC treatment may alleviate symptoms associated with chronic pain. The goal of this observational and longitudinal study was to examine patients using MC to treat chronic pain pre versus post MC treatment. These interim analyses included 37 patients with chronic pain evaluated prior to initiation of MC treatment and following 3 and 6 months of MC use; pain, clinical state, sleep, quality of life, and conventional medication use were assessed. Correlation analyses examined the relationship between changes in pain and...

Abstract Cannabis is one of the most used drugs of abuse in the world. The objective of this study was to analyze the effects of smoking cannabis on vision and to relate these to those perceived by the user. Thirty-one cannabis users participated in this study. Visual function assessment was carried out in a baseline session as well as after smoking cannabis. We evaluated static visual acuity, contrast sensitivity, stereoacuity, accommodative response, straylight, night-vision disturbances (halos) and pupil size. The participants were also divided into two groups depending on whether they perceived their vision to have worsened after smoking cannabis. A logistic regression analysis...

Abstract Cannabis sativa is one of the oldest medicinal plants used by humans, containing hundreds of bioactive compounds. The biological effects and interplay of these compounds are far from fully understood, although the plant’s therapeutic effects are beyond doubt. Extraction methods for these compounds are becoming an integral part of modern Cannabis-based medicine. Still, little is known about how different methods affect the final composition of Cannabis extracts and thus, their therapeutic effects. In this study, different extraction methods were tested, namely maceration, Soxhlet, ultrasound-assisted extraction (UAE), and supercritical CO2 extraction methods. The obtained extracts were evaluated for their cannabinoid content, antioxidant properties, and in vitro bioactivity on human...

Abstract Background The use of cannabis for symptoms of endometriosis was investigated utilising retrospective archival data from Strainprint Technologies Ltd., a Canadian data technology company with a mobile phone application that tracks a range of data including dose, mode of administration, chemovar and their effects on various self-reported outcomes, including pelvic pain. Methods A retrospective, electronic record-based cohort study of StrainprintTM users with self-reported endometriosis was conducted. Self-rated cannabis efficacy, defined as a function of initial and final symptom ratings, was investigated across the included symptom clusters of cramps, pelvic pain, gastrointestinal pain, nausea, depression, and low libido. Cannabis dosage form, dose and cannabinoid ratio...

Abstract Background The opioid overdose epidemic in Canada and the United States has become a public health crisis - with exponential increases in opioid-related morbidity and mortality. Recently, there has been an increasing body of evidence focusing on the opioid-sparing effects of medical cannabis use (reduction of opioid use and reliance), and medical cannabis as a potential alternative treatment for chronic pain. The objective of this study is to assess the effect of medical cannabis authorization on opioid use (oral morphine equivalent; OME) between 2013 and 2018 in Alberta, Canada. Methods All adult patients defined as chronic opioid users who were authorized medical cannabis...

Abstract We examined knowledge and practice of harm reduction strategies among people who use cannabis attending an annual public cannabis advocacy event. We also assessed the sources from which they glean information about cannabis. Participants (n = 472) completed a brief survey assessing cannabis use, sources for information on cannabis, and harm reduction strategies. Participants’ knowledge of cannabis was based mostly on their own experiments and experiences rather than on information from health professionals. Participants generally had low accuracy in identifying effective harm reduction techniques and low rates of utilizing effective harm reduction techniques, using them at...
