Abstract In the present work, Cannabis sativa L. cv Futura 75 inflorescences, cultivated in the Abruzzo territory, were characterized for their volatile fraction through SPME-GC-MS. In addition, the essential oil extracted from these inflorescences was investigated for the antioxidant potentialities and for the terpenic profile. The antibacterial activity of hemp essential oil (HEO) against some pathogenic and spoilage microorganisms isolated from food was also evaluated by determining the minimal inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC). The results showed significant antioxidant capacity (DPPH: 63.38 ± 0.08 mg TE/g HEO; FRAP: 438.52 ± 6.92 mg TE/g HEO) alongside good antibacterial activity against Gram-positive...

However, we have yet to determine if this relationship is maintained when controlling for important confounding variables. The following systematic review aims to investigate if the association between cannabis use and psychotic outcomes is preserved when accounting for important confounders, and if discontinued use mitigates any potential negative impacts. Areas covered: The authors conducted an exhaustive search of the MEDLINE database and Google Scholar to identify articles pertaining to the systematic review. Thirty-three articles were retained for meeting the...

Abstract Background Amidst cannabis legalization efforts and laws, we do not fully understand how the youngest frequent cannabis users fare during young adulthood. This study aims to 1) examine the prevalence of cannabis use during adolescence, and 2) investigate links of frequent (i.e., weekly or daily) teenage cannabis use with psychopathology and functional well-being at age 20—compared to no or occasional use. Methods Data came from a prospective-longitudinal cohort study (assessments from 2004 to 2018, from ages 7–20) in an urban setting (N = 1482). Substance use was assessed with self-reports between ages 13 and 20. At age 20, participants reported on psychopathology (psychotic...

Abstract Cannabis is a complex mixture of hundreds of bioactive molecules. This provides the potential for pharmacological interactions between cannabis constituents, a phenomenon referred to as “the entourage effect” by the medicinal cannabis community. We hypothesize that pharmacokinetic interactions between cannabis constituents could substantially alter systemic cannabinoid concentrations. To address this hypothesis we compared pharmacokinetic parameters of cannabinoids administered orally in a cannabis extract to those administered as individual cannabinoids at equivalent doses in mice. Astonishingly, plasma cannabidiolic acid (CBDA) concentrations were 14-times higher following administration in the cannabis extract than when administered as a single molecule. In vitro transwell assays identified CBDA as...

Such studies do not provide information about whether individuals are substituting Cannabis for opioids at different points in time. The current study assessed the magnitude of the daily association between Cannabis and opioid use in individual adults with and without pain who use non-medical opioids. Design Prospective cohort study. Setting The greater New York area and a suburban inpatient addiction program. Participants Adults with problem substance use who use non-medical opioids, recruited from May 2016–June...

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...
